What Is Periodontitis?
Periodontitis is a chronic inflammatory disease affecting the supporting structures of the teeth—primarily the gums, periodontal ligament, and alveolar bone.

The Hidden Power of Flossing: More Than Just Clean Teeth

The Foundation of Your Dental Structure
Your teeth may seem like standalone structures, but they rely on a complex network of tissues to stay firmly anchored in your jaw.

Often overlooked in discussions about dental anatomy, the PDL is a delicate yet resilient connec...
Understanding Cementum: A Vital Component of Your Teeth
Cementum is a specialized calcified tissue that plays a crucial role in anchoring your teeth securely within the alveolar bone.

The Vital Core of Your Teeth: What Is Dental Pulp?
Dental pulp is the innermost layer of a tooth, containing a network of nerves, blood vessels, and connective tissue.

Without it, your teeth w...
The Science Behind Enamel: Your Teeth’s Hardest Tissue
Enamel is the outermost layer of your teeth, a biomineralized tissue composed primarily of hydroxyapatite crystals embedded in an organic matrix.

The Primary Function of Molars: More Than Just Chewing
Molars are the unsung heroes of your mouth—large, multi-cusped teeth designed for grinding, crushing, and breaking down food into manageable, swallowable pieces.

Thei...
Why Incisors Are More Than Just "Front Teeth"
Incisors—the eight sharp, chisel-shaped teeth at the front of your mouth—are often overlooked despite their critical functions.

Understanding Primary Dentition: The Foundation of Oral Health
Children’s teeth, known as primary (deciduous) dentition , play a crucial role in speech development, chewing, and establishing proper alignment for permanent teeth. Unlike adults, who typically have 32 teeth , children begin life with a complete set of 20 primary teeth —10 in the upper arch and 10 in the lower. These teet...
The Short Answer: A Healthy Adult Smile Has 32 Teeth
Most adults have a full set of 32 permanent teeth , including four wisdom teeth (third molars).

This prospective observational multicenter study demonstrated successful functional and esthetic outcomes of the study implant restorations (single tooth restoration, fixed partial dentures) with reliable peri-implant hard and soft tissue stability and high patients’ satisfaction. The results are comparable with the outcome of already published controlled randomized clinical studies and retrospe...
In recent years, patients’ needs have increased in terms of the esthetic and functional outcome of the dental restoration. PROMs have been reported in several studies and represent a well-described non-invasive method to measure patient’s satisfaction with these needs; however, they might present a lack of standardization [39, 40] due to the very subjective view on esthetics or functionality o...
Changes in crestal bone level are well-documented in the literature. Bone remodeling is reported to take place between surgery and loading. The reported changes are generally around 0.5 mm [17, 27, 30] but can reach more than 1 mm [31] in randomized or observational trials. The present study is well in accordance with these findings with its bone remodeling of − 0.52 ± 0.55 mm. Nearly 45%...
Endosseous dental implants are a commonly accepted treatment procedure and showed high survival and success rates as well as good functional performance in numerous clinical trials and retrospective analyses, also for Conelog implants as for their specific implant surface [17, 23, 26]. However, in general, one could argue that results of controlled clinical studies do not reflect the real situatio...
Table 3 shows the mean bone level changes of the implants with available radiographs from insertion to 5-year post-loading. Bone remodeling around the implant was noticeable from surgery to loading, presenting a mean value of − 0.52 ± 0.55 mm. From loading to the 5-year follow-up, the mean change in crestal bone remained clinically stable (−0.09 ± 0.43 mm) (Fig. 3).

The study was started with 94 patients with 130 implants. At the end of the study (5-year post-loading), 76 patients with 104 implants were considered for analysis. Dropouts were distributed over the time of the study as described in Table 1. The majority of dropouts occurred early in the study phase. The reasons for the dropouts were variable as described in Fig. 1.

The study data, soft and hard tissue parameters as well as the PROMs were descriptively analyzed using IBM SPSS V25.0 (IBM Corp., Armonk, NY, USA): Categorical variables were shown with frequencies and mean values were used for continuous variables. Survival analysis was performed using Kaplan–Meier method. Time of loading was the study baseline as per protocol, and the statistical unit was the ...
Patients were scheduled to follow-ups at 6 months, 1-, 2-, 3-, 4-, and 5-year post-loading for the assessment of the study parameter (Fig. 1). Depending on the investigators’ standard post-operative protocol, follow-up appointments were scheduled slightly differently: One center skipped the control visits at 6 months. Additionally, due to the observational character of the study and the pati...
This is an observational multicenter clinical study, approved by the ethics committee of the Freiburg ethics commission international (feci 010/1833).

A minimum of 90 to 100 patients were planned to be included...
Features of the chosen implant system for a study may also influence the outcome of the treatment: The degree of the manufacturer’s tolerances of implants with a conical implant-abutment connection heightens the risk of a mispositioning of the abutment, which cannot be corrected by repeated torqueing. Platform switching (PS) implants tend to have a protective effect on hard implant tissue outcom...
Many randomized controlled clinical trials have been published about dental implants. They have demonstrated long-term success in the rehabilitation of edentulous patients [1, 2] as well as patients with single or multiple teeth replacements [3, 4].
While this type of trials have an indispensable place in establishing a new product or a new operation technique regarding safety and efficacy, the r...
The interpretation of the results of randomized clinical trials is often questioned in relation with daily circumstances in practices. This prospective observational multicenter study was instigated to reflect the need for information in real-life situations with dental implants with internal conical implant-abutment connection (Conelog implant system). The implants were followed up at least 5-yea...

This survey served to clarify the current status of implant prosthodontics, issues, and considerations in their fabrication, and the status of prosthetic complications and preventive initiatives, all from a laboratory perspective.
Concerning implant treatment, it was concluded that dentists either play the leading role or work in collaboration with technicians, including in the formulation of tre...
Finally, technicians gave voice to the several requests for dentists, who are their customers, as a result of their daily experiences accomplishing implant laboratory procedures (Q14) (Figure 9). These included asking dentists to use suitable implant location and orientation (31.8%), to allow technicians to participate and consult with technicians from the treatment planning stage (28.3%), to imp...
The questionnaire revealed several creative steps, based on laboratory considerations, being taken to prevent veneer chipping and fractures, a frequent and problematic prosthetic complication (Q12) (Figure 7). Technicians were taking into account metal (including zirconia) coping designs (36.3%), covering only the distal-most part of the molar region with metal (24%), using veneering composite re...
Looking at repair requests (i.e., complications) involving the superstructures of fixed implant prostheses (Q11) (Figure 6), facing damage and chipping accounted for more than half of all requests (54.5%). Generally speaking, there are many reports that indicate a high incidence of complications related to fixed prostheses involving abutment screw loosening, detachment of cement-retained crowns, ...
Bar and clip attachments were most commonly used for IODs, followed by magnet, ball, and socket, and Locator attachments (Q8) (Figure 4). It is noteworthy among the questionnaire results that magnetic attachment use is highest in Asian countries, including Japan [43]. Additionally, it is thought that the low use of Locators (5.2%) is strongly influenced by Japan’s strict pharmaceutical regulati...
Concerning the types of prostheses used in the posterior region (Q6) (Figure 3), PFM design accounts for about 40% of the total, although the questionnaire also revealed a trend (in 9.1% of all cases) toward metal occlusal designs to avoid fracture and chipping of the veneer material. The same trend is evident in indirect composite facing crowns, where metal occlusal designs are used in about 35%...
Next, concerning the types of abutments used with cement-retained prostheses (Q4) (Figure 1), CAD/CAM abutments accounted for about one third of the total (titanium, 19.7%; zirconia, 12.1%), and custom UCLA-type abutments made from cast gold alloy accounted for about the same proportion. It is likely that this breakdown is because, in many cases, implant systems using fabricated crowns are not su...
Dentists play a leading role in 39.3% of the time in implant treatment planning and prosthetic design, and dental technicians are consulted concerning cases and part usage 34.7% of the time, suggesting the approach to implants is driven by prosthetic considerations (by dentists) to some degree. However, because dental technicians indicated that they take the initiative 15% of the time, it is impos...
Out of 120 surveys sent, 74 technicians responded, resulting in a response rate of 61.6%. A summary of the responses is provided in Tables 1, 2, 3, and 4 and Figures 1, 2, 3, 4, 5, 6, 7, 8, and 9.
Because implant treatment (implant prostheses) requires a significant amount of specialized, high-precision laboratory procedures, this area of dental care exhibits slightly different trends than pros...
This cross-sectional questionnaire survey was performed among the certified dental technicians of JSOI from September to December in 2011.

To facilitate coverage of a broad range of topics, the survey classified content into the following four ca...
This survey consists of a questionnaire targeting the certified dental technicians of the Japanese Society of Oral Implantology (JSOI) [32] who are primarily involved in fabricating dental implant restorations. It was formulated to clarify the current status of implant prostheses from a prosthetic and technician-oriented standpoint through questions addressing current trends among dental implant t...
Currently, dental implant treatment is evaluated on the basis not only of restoring masticatory function, but also a variety of other factors, including the implant and superstructure survival rate and psychological impacts [1-3]. Numerous factors must be taken into account, to offer highly predictable implant treatment, and there is no doubt that prosthetic-related factors such as the type and co...
There are many implant cases in which dental technicians take initiative with regard to the design of implant prostheses, and to a certain extent, this area of care is one in which dentists do not necessarily play the leading role. Moreover, inadequate communication between dental technicians and dentists and insufficient instructions for technicians has been highlighted as issues in the past. The...

In the present study, which aimed to verify the biomechanical effects of offset placement on peri-implant bone, we created multiple finite element models and models where implants were actually placed. We compared the compressed displacement as well as the strain and stress distribution in the peri-implant bone between both kinds of models, and the results can be summarized as follows:
Central lo...
Concentration of stress in the loading-side peri-implant bone was observed in all placements and for both the experimental and the FEA models. Considerable stress was also found to be concentrated in the no. 36 peri-implant bone in buccal loading with buccal offset and lingual loading with lingual offset. Similar to the strain results, stress was observed in a large range under conditions where th...
Similar trends were observed in the direction and magnitude of displacement between placements. Buccal loading exhibited considerable motion towards the buccal rotation/tilting of the implant bodies, and lingual loading exhibited little motion towards lingual displacement. This corresponds to the fact that there was more compressed displacement during buccal loading than during lingual loading.
I...
Moreover, considering the possibility of error while using an implant placement guide, we created many FEA models for each placement to compare the accuracy between the same placement models used with different FEA models.
Most studies verifying the usefulness of offset placement used a single technique for analysis [8–19]. Therefore, the results regarding the usefulness of offset placement var...
Reported studies verifying the effects of offset placement include ones where implant bodies were embedded in rectangular experimental models [11–14], ones where rectangular bone models were constructed with FEA models [15, 16], and ones where FEA models were constructed from CT data on human mandibles [17, 18]. The artificial mandible models used in the present study were type II in the Lekholm...
Figure 11 and Table 4 show the strain, by loading site, in the implant part corresponding to the first molar in the experimental models during the application of a 100-N vertical load.
Considerable compressive strain was observed with the load-side strain gauges in all placements, and similar trends were observed between placements. As much as about 4500 με of compressive strain was observed...
Figures 8 and 9 and Tables 2 and 3 show the results for the compressed displacement of the implants, by loading site, during the application of a 100-N vertical load in each of the models.
In all placements, the compressed displacement in the experimental models and FEA models was greatest with buccal loading and smallest with central loading at the three loading points. For both the experiment...
The places on the experimental models where the strain gauges were applied were represented as coordinate points on the FEA models, and the strain in the FEA models was calculated by dividing the change in length between before and after loading by the length of the strain gauges.
An equivalent stress occurring in the peri-implant bone during loading was observed and assessed in a buccolingual cr...
Implant displacement under loading conditions was measured using an Instron-type universal testing machine (Instron-5500R®, Instron Japan, Kanagawa, Japan) for the experimental model. The experimental models were placed on the worktable of an Instron-type universal testing machine, and compression tests were performed using a conical jig. A vertical load was applied at a rate of 0.5 mm/s on the ...
Four two-wire strain gauges (KFR-02N-120-C1-11, Kyowa Electronic Instruments, Tokyo, Japan) were applied to the no. 36 peri-implant bone surface [21]. The surface of the measurement site was polished with no. 320 sandpaper and then wiped clean with acetone, following which they were adhered with a special adhesive (CC-33A, Kyowa Electronic Instruments, Tokyo, Japan). The strain gauges were applied...

Bone remodeling to maintain osseointegration between the bone and implant is absolutely essential to ensure favorable results and long-term stability in implant treatment [1, 2]. Bone remodeling requires that various stresses generated around the bone caused by the occlusal load applied to the implant be within an appropriate range. The concentration of stress at the bone-implant interface, caused...
Offset placement may not necessarily be more biomechanically effective than straight placement in edentulous posterior mandibles.
Proper implant placement is very important for long-term implant stability. Recently, numerous biomechanical studies have been conducted to clarify the relationship between implant placement and peri-implant stress. The placement of multiple implants in the edentulous posterior mandible has been studied by geometric analysis, three-dimensional finite element analysis (FEA), model experimentation, ...

In this limited study, there was a significant correlation between neuroticism character and diastolic blood pressure or mean blood pressure rising in patients who received implant surgery.
On the other hand, there was no correlation between SBP and neuroticism character. For this reason, it is thought that the range of SBP is usually wide compared to DBP. However, there are some reports about the correlation between SBP and patients’ personality trait [20]. Besides, the excessive rise in SBP during the operation may adversely affect the condition of the patients. Therefore, a furt...
The blood pressure is considered to be affected by many factors, including physical and psychological stress in dental treatment. From a physical aspect, there are many reports about the relationship between blood pressure and local anesthesia or pain [8–11].
In fact, Tsuchihashi et al. reported that there was a correlation between increased blood pressure and infiltrated anesthesia amount [12]...
Ten females and five males (mean 55.5 ± 10.6 years) were evaluated in this study (Table 1). Tables 2 and 3 show the patients’ blood pressure, pulse rate, and NEO-FFI scores. Average values of blood pressure and pulse rate at the first visit were 121.2 mmHg; SBP, 74.9 mmHg; DBP, 90.4 mmHg; MBP, 81.6 bpm; PR, RPP, 9791 bpm × mmHg and 143.0 mmHg; SBP, 87.1 mmHg; DBP, 105.7 mmHg...
Fifteen patients were recruited for the present study. All the patients had never received implant treatment in the past.

Implant prosthesis has already become one of the treatment options for missing teeth. In addition, under the appropriate maintenance therapy, its longevity is equal or higher compared to the other prosthetic treatments. On the other hand, patients who want to receive the implant treatment cannot avoid the insertion surgery. In addition, if there are hard or soft tissue defects at the planned site,...

To overcome the shortcomings of this case reports, prospective, multicenter, and controlled studies must follow to affirm a potential relationship between vitamin D deficiency, osteoimmunology, and the early failure of dental implants. Currently, a general recommendation for a standardized vitamin D screening in dental implantology cannot be stated due to lack of evidence.
Nevertheless, the vitamin D deficiency prevalence in the European population indicates that a vitamin D deficiency is probably not a sole causative factor for early implant failure; otherwise, the early implant failure rate would be significantly higher. However, a synergistic effect with other factors is conceivable. Some authors stated that implant osseointegration is not simply a wound healing ...
Local and systemic factors can affect the survival rate of dental implants [30–33]. The causes of early implant failure are not fully clarified and an association between vitamin D and dental implant osseointegration has not been investigated properly [8, 13–16]. Some recent animal studies in rodents demonstrated a relationship between vitamin D supplementation and an increased bone to implant...
In this 51-year-old male patient, no grafting procedure was performed as vertical and horizontal alveolar ridge dimension was adequate for implant placement. The implant placement in regions 36 and 37 was performed as guided surgery (Fig. 2a, Table 1). The implant placement was uneventful and the bone appeared clinically healthy. A cortical bone profiling was performed during implant placement. ...
The medical history of this 48-year-old male patient showed a high blood pressure; otherwise, the patient was healthy. A successfully completed periodontal therapy was done before implant therapy. The patient demonstrated stable marginal bone levels. Autologous retromolar bone grafting using local anesthesia was performed in the left mandible (see Fig. 1a). This patient received a postoperative o...

Long-term stable osseointegrated implants are the primary goal in dental implantology. Although dental implants have proven clinical reliable in the long term, the failure of implants at a very early stage of osseointegration has been described [1, 2]. The pursuit to identify the mechanisms leading to early implant failure is ongoing to date and include the following: tobacco usage, diabetes, wear...
An association between vitamin D deficiency and early dental implant failure is not properly verified, but its role in osteoimmunology is discussed. This article illustrates two case reports with vitamin D deficiency and early implant failure. Prior to implant placement, the first patient received crestal bone grafting with autologous material. Both patients received dental implants from different...

Under the ideal conditions of the study herein, the application of a 30-Ncm reverse torque at the time of the stage 2 surgery, before the prosthetic restoration, allowed the clinical identification of the stability of 40 dental implants.
Primary stability depends on the micro and macroscopic characteristics of the dental implant. Thus, after the application of a 30-Ncm reverse torque, both implan...
In order to exclude risk factors, as there are no previous researches on reverse torque in humans, the research was made following a conventional protocol, only on lower jaw implants, with implants of treated surface, which have benefits that greatly compensate for the risks, allowing for faster osseointegration levels because the rugosity increases the contact surface between the implant and the ...
The reverse torque technique proposed by Roberts in 1984 to evaluate dental implants integration proved to be successful. The most recent researches are aimed at evaluating current results. Thus, the objective of this research was to evaluate, by means of the 30 Ncm reverse torque test, 40 dental implants on the lower jaw, during the stage 2 surgery, as a mechanical and clinical, non-invasive tre...
This study reports on the clinical behavior of 40 dental implants placed on the lower jaw, on ideal bone, and under ideal surgical and systemic conditions, subjected to a 30-Ncm reverse torque during the stage 2 surgery, on 17 patients.
The patients evaluated only showed normal signs and symptoms of post-operatory swelling. According to the distribution of the implants on the mandibular region, 2...
On the data collection table, the existence of any peri-implant radiolucency radiographic images previous to the stage 2 surgery was recorded. After the application of the 30 Ncm reverse torque, the presence or absence of dental implant movement was recorded, as well as any incidence of symptomatology (pain), or presence of any clinical signs.
A clinical trial was carried out, in which 17 patients treated with implants at the School of Dentistry of the Santa Maria University and which had had 40 dental implants placed from two different commercial brands, with NanoTec™ and Vellox® surfaces, on the lower jaw, with the approval of the Bioethics Committee of the Santa Maria University (Fig. 1).

The reverse torque test proposed by Roberts et al. in 1984, and developed by Johansson and Albrektsson in 1987 [6], is considered as a special advantage in stage 2 surgery, because it represents a definitive clinical verification of initial integration of the dental implant with the bone surface. The torque level required is commonly expressed in Newton centimeters (Ncm) [7, 8].

Primary stability has been reestablished as a previous clinical requirement to achieve osseointegration.

The analysis for the ratio of access-hole with or without marginal staining at the time of T = 12 M showed that the results in group CR (12/16) and in group M4M (12/16) were the same. For this reason, the marginal discrepancy pattern, different in both groups did not influence the aesthetical result. The occlusal contact point (A, B, or C) was compared to the marginal staining rate. Among the...
Focusing on numbers of access-hole showing a disappearance of the overfilling in an early period (up to T = 3 M), groups CR and M4M exhibited 82% (23/28) and 39.3% (11/28), respectively (Table 4). This can be explained by the differences of mechanical properties of both materials. The elastic moduli of M4M and CR are 1.9 and 7.9 MPa, respectively. Flexural strength of M4M is 66 MPa which i...
The in vivo evaluation is quite different from that of the in vitro analysis. In the previous study, all the specimens were calibrated to a flat surface with 2.5 mm diameter. In present study, each access hole had a different dimension and configuration. The filling surfaces were often ø3 to 4 mm in diameter. Access-holes located in the occlusal groove area or in the inclined cusp surface induc...
Nowadays, implant screw-retained prosthesis becomes a popular mode of implant supra-structure restoration. Cement retained implant restoration has issues including irretrievability and difficulty of controlling the cement excess beyond the abutment joint. The cement excess can be a major cause of peri-implantitis [13,14,15]. Screw-retained implant restoration has also some disadvantages including ...
Among the 56 access holes, no filling was dislodged during 12 months, and no complaint was registered from the patients regarding functional and aesthetical aspects.
The results for surface areas changes of access-hole fillings at respective intervals were summarized in Table 3 and Fig. 6. The mean values of the change from T = 1 M to T = 12 M were 77.1 ± 13.1% for group M4M and...
The marginal depth of the access-hole filling at T = 0, T = 1 M, T = 3 M, and T = 6 M could not be defined successfully because of the overfilling phenomenon which disrupted the measurement of marginal gap depth and angle (Fig. 3a–e). Only the marginal depth and angle at T = 12 M could be measured with the same digital microscope, and the mean value for each group was ca...
Patients who received a metal framed ceramic screw retained implant crown or bridge were included in this study. These access holes were delimited only by ceramic.

The retention of implant-supported prostheses is provided by the use of a screw or cement. Recently, it was demonstrated that cement-retained prostheses had a higher rate of technical and biological complications [1], despite a better passive fit than the screw-retained restorations [2]. The CAD/CAM development of the implant-supported prostheses allows a better passively fit with screw-retained p...
Screw retained implant prostheses seem to be an efficient restorative method to prevent peri-implantitis caused by cement excess around the abutment. The drawback of the screw-retained prostheses is the difficulty to realize an efficient access-hole filling functionally and aesthetically. Up to now, few in vitro and in vivo studies were reported in the literature. The aim of this study was to eval...

This study is an attempt to identify patient satisfaction with mini-implant overdentures compared to standard diameter implant-supported overdentures in completely edentulous patients. Implant-supported overdentures have been reported to offer many advantages like decreased bone resorption, reduced prosthesis movement, better esthetics, better occlusion and tooth positioning, improved occlusal loa...

Implants have been considered to improve treatment outcomes of completely edentulous patients with anatomical challenges compromising the retention and stability. The root form dental implants which are 3–5 mm in diameter are considered standard diameter implants while less than 3 mm diameter implants are termed mini-implants [1]. Initially, mini-implants were used as a temporary measure, with...

Within the limitations of this in vitro study, the following conclusions could be drawn:
Implant design, superstructure material, and load direction significantly affect peri-implant microstrains.
The recorded compressive and tensile microstrains for the tested designs were within the physiologic loading range, as they did not exceed the compressive or tensile strength of the bone-implant interf...
Regarding the effect of superstructure material on induced microstrains, generally, different implant designs supporting Lava Ultimate crowns showed higher mean microstrain values(1927.3 ± 1536.6 μɛ), in comparison with those supporting metal crowns (1313.7 ± 973.1 μɛ).Theoretical considerations [44, 45] and in vitro experiments [46,47,48,49] suggest that an occlusal material with ...
Regarding the effect of direction of loading on induced microstrains, it was shown that changing the position of occlusal loading had a considerable effect on the amount of distribution of stresses where axial loading generated even distribution of load around the implant in comparison to off-axial loading where stresses were more pronounced in the area of load application. This might be due to th...
Previous studies have shown that direct correlations exist between microstrain magnitudes and bone stability/instability conditions. This has been summarized by Frost, when bone is loaded below about 2000 microstrains, bone can easily repair what little microdamage occurs. Yet, when pathologic overloading occurs (over 4000 microstrains), stress and strain gradients exceed the physiologic tolerance...
To replace a missing lower molar in compromised ridge, different treatment options were suggested, using either a standard size implant with surgical procedures, short-wide implant, or two mini implants. Concerning the use of mini implant, splinted multiple implants increase the surface area that interfaces with the bone to lessen the per square millimeters of force borne by the bone [11]. The imp...
Results revealed that standard implant showed the statistically significantly highest mean microstrain values (3362.4 ± 757.4 μɛ). Double mini implant showed statistically significantly lower mean microstrain values (801.6 ± 251.4 μɛ), while short-wide implant showed the statistically significantly lowest mean microstrain values (697.6 ± 79.7 μɛ), with a P value
Data were presented as mean and standard deviation (SD) values. Data were explored for normality by checking data distribution and histograms, calculating mean and median values, and finally using Kolmogorov-Smirnov and Shapiro-Wilk tests of normality. Stress data showed non-parametric distribution, so the Kruskal-Wallis test was used to compare between the types of implants. The Mann-Whitney U te...
Each crown was cemented to its corresponding implant-abutment assembly using temporary cement (Cavex Temporary Cement, Cavex, Holland).
Each implant received 4 strain gauges (Kowa strain gages, Japan) placed on the mesial, distal, buccal, and lingual surfaces of the epoxy resin adjacent to the implants. At these selected sites, the thickness of the epoxy resin surrounding each implant was reduced...
In the present study, the following materials were used: titanium root form endosseous implants of standard diameter and length (4-mm platform, 3.8-mm diameter,12-mm length, fixture bevel 0.2 mm, Super Line System, Dentium, USA), short-wide implant (7-mm platform, 5.8-mm diameter, 7-mm length, Super Line System, Dentium, Seoul, Korea) with 1.5-mm machined surface and 5.5-mm threaded surface that ...
There are several factors that affect force magnitudes in peri-implant bone. The application of functional forces induces stresses and strains within the implant prosthesis complex and affect the bone remodeling process around implants [8, 9].
While there are several methods of measuring strain, the most common is with a strain gauge, a device whose electrical resistance varies in proportion to t...
The molars are one of the first teeth to be lost over lifetime; thus, their replacement is frequently needed. Implantation is generally the preferred choice to replace a missing single tooth avoiding vital teeth preparation and bridge fabrication [1].
The mandibular bone loss occurs as knife-edge residual ridge where there is marked narrowing of the labiolingual diameter of the crest of the ridge...
The aim of this study was to evaluate the biomechanical response of the peri-implant bone to standard, short-wide, and double mini implants replacing missing molar supporting either hybrid ceramic crowns (Lava Ultimate restorative) or full-metal crowns under two different loading conditions (axial and off-axial loading) using strain gauge analysis.

Within the limits of this prospective cohort study, narrow-diameter implants (2.75 to 3.25 mm) can be successfully used as a minimally invasive alternative to horizontal bone augmentation in posterior mandible up to 1 year of function. This outcome could be related to the fact that these implants have been all splinted to other implants by a fixed prosthesis. These preliminary results must be co...
On the one hand, due to the small sample size of this study and moreover, the short follow-up (only 1 year after loading), it would be hazardous to conclude that the placement of NDIs to support fixed prostheses in posterior mandible is a predictable treatment modality. In order to draw more reliable conclusions, we need to wait for longer follow-ups, since it may be possible that after several y...
Dental implants with a reduced diameter are commonly used where bone width is narrow or in cases of restricted mesiodistal anatomy such as laterally maxillary and mandibular incisors. They could also be a viable alternative to bone augmentation especially in challenging situations such as the posterior regions of the mandible. While it has been shown that it is possible to horizontally augment bon...

Forty-eight patients were screened for eligibility, but six subjects were not included for the following reasons: five patients (10.4%) were hesitant to receive implant treatment, and one patient (2.1%) was treated with intravenous amino-bisphosphonates. Forty-two patients were then considered eligible and were consecutively enrolled in the study. All patients were treated according to the allocat...
Primary outcome measures were as follows:
Implant failure: evaluated as implant mobility and removal of stable implants dictated by progressive marginal bone loss or infection. The stability of each implant was measured manually by tightening the abutment screw with a wrench delivering a torque of 20 Ncm. Implant stability assessment was performed at delivery of definitive crowns (3 months afte...
The present prospective study was conducted at a private practice (Tommaso Grandi, Modena) in Italy between October 2014 and January 2016.

The aim of this cohort study was to evaluate the outcome of narrow-diameter implants (2.75 and 3.25 mm diameter) used as definitive implants in patients with insufficient bone ridge thickness for placing standard-diameter implants in posterior regions of the mandible. The present study reports the clinical outcome up to 1 year after loading. It is planned to follow up this patients’ cohort to ...
Historically, implants have been used and documented mainly with diameters between 3.7 and 4.3 mm. Employing these diameters for numerous indications, scientifically substantiated treatment protocols with excellent long-term results have been established [1]. One disadvantage of a standard-diameter implant is the fact that, in clinical use, the available horizontal crestal dimensions of the alveo...

We examined clinical parameters in patients receiving long-term implant maintenance. There were significant differences between the H and HP groups in age at the time of maintenance, number of natural teeth at the beginning of implant treatment, total number of extracted teeth, and maintenance. The prevalence of implant-based peri-implantitis was 10.8% of all the implants. All implants with peri-i...
A correlation between the PPD of the peri-implant tissue and lesion progression has been reported, similar to that seen with periodontitis [27]. Probing around the implant is useful for evaluating soft tissue inflammation and is considered reproducible [36]. Examination of peri-implant bleeding is reported to have higher diagnostic accuracy than probing around natural teeth [37]. However, because ...
BoP has been used to evaluate inflammatory conditions of periodontal tissue [33] and can also be an important evaluation item for peri-implant tissues. To avoid diagnosing bleeding resulting from strong probing as a false positive, we set the probing pressure to 0.15 N [34]. BoP values were low, with no significant difference between the groups (H group, 0.30; HP group, 0.28). This result was sim...
All the implants with peri-implantitis came from the HP group, not the H group, thus supporting the view that a history of periodontitis is a risk indicator for peri-implantitis. In the diagnosis of periodontitis within the HP group, it is notable that peri-implantitis increased as periodontitis become more severe. This supports the findings of a previous study that reported that the survival rate...
In this study, we reviewed the clinical parameters of 130 implants in 55 patients during ongoing long-term maintenance. We focused on the history of periodontitis and compared the parameters in two groups classified according to a history of periodontitis. A previous study on the prevalence of periodontitis revealed that moderate or severe periodontitis was observed in 64% of people over 65 years...
Because normality and homoscedasticity were not obtained for each clinical parameter between the two groups, a statistical study was conducted using the nonparametric test (Mann–Whitney U test) for the difference test between the two groups. PPD was recognized to be significantly greater (p
Of the 55 subjects, 25 were male and 30 were female (H group: 8/10, HP group: 17/20, respectively). A total of 130 implants (H group 39, HP group 91) were included in the analysis (Table 2). The mean maintenance period was 6 years and 6 months. The average number of natural teeth at the first visit and at the beginning of implant treatment were 25.3 ± 2.9 and 22.4 ± 4.5, respectively. Com...
At the time of optional maintenance, the following parameters were measured for each implant. Data collection and analysis were conducted by two operators who were blind to the research purpose and methods. One operator statistically analyzed the final data set.

This study enrolled 55 patients (25 men, 30 women; mean age, 63.53 ± 10.51 years) who visited Nihon University School of Dentistry Dental Hospital for implant maintenance from April to September 2016. The inclusion criteria were treatment at the same hospital with two-stage implant placement before 2015, and ongoing maintenance at 3–6-month intervals after superstructure placement. Patients ...
Peri-implant diseases are the main biological complication of implant treatment and greatly influence treatment success [1]. Risk indicators for peri-implantitis include a history of periodontitis, poor oral hygiene, and smoking [2,3,4]. Peri-implantitis is often encountered clinically, occurring in 12 to 43% of implants and 28 to 47% of implant patients [5,6,7,8]. Similarities between the patholo...
The pathophysiology and pathology of peri-implantitis remain unclear; however, its similarity to periodontitis has been described. The evaluation of peri-implant tissue and the diagnostic criteria of peri-implant disease are not currently standardized as they are for periodontitis. In this study, we evaluated clinical parameters during the implant maintenance period to determine significant correl...

Under the ideal conditions of the study herein, the application of a 30-Ncm reverse torque at the time of the stage 2 surgery, before the prosthetic restoration, allowed the clinical identification of the stability of 40 dental implants.
Primary stability depends on the micro and macroscopic characteristics of the dental implant. Thus, after the application of a 30-Ncm reverse torque, both implan...
In order to exclude risk factors, as there are no previous researches on reverse torque in humans, the research was made following a conventional protocol, only on lower jaw implants, with implants of treated surface, which have benefits that greatly compensate for the risks, allowing for faster osseointegration levels because the rugosity increases the contact surface between the implant and the ...
The reverse torque technique proposed by Roberts in 1984 to evaluate dental implants integration proved to be successful. The most recent researches are aimed at evaluating current results. Thus, the objective of this research was to evaluate, by means of the 30 Ncm reverse torque test, 40 dental implants on the lower jaw, during the stage 2 surgery, as a mechanical and clinical, non-invasive tre...
This study reports on the clinical behavior of 40 dental implants placed on the lower jaw, on ideal bone, and under ideal surgical and systemic conditions, subjected to a 30-Ncm reverse torque during the stage 2 surgery, on 17 patients.
The patients evaluated only showed normal signs and symptoms of post-operatory swelling. According to the distribution of the implants on the mandibular region, 2...
On the data collection table, the existence of any peri-implant radiolucency radiographic images previous to the stage 2 surgery was recorded. After the application of the 30 Ncm reverse torque, the presence or absence of dental implant movement was recorded, as well as any incidence of symptomatology (pain), or presence of any clinical signs.
A clinical trial was carried out, in which 17 patients treated with implants at the School of Dentistry of the Santa Maria University and which had had 40 dental implants placed from two different commercial brands, with NanoTec™ and Vellox® surfaces, on the lower jaw, with the approval of the Bioethics Committee of the Santa Maria University (Fig. 1).

Since the study herein is not found in humans [5, 9], last phase of study, and counting on previous results from in vitro and in vivo researches with animal models on long bones (femur, tibia, mandibles) in dogs, pigs, baboons, rabbits, and even in mastoid bones [6, 9–16], which provide necessary information to design human trials, this mechanical test was performed on dental implants in humans,...
The reverse torque test proposed by Roberts et al. in 1984, and developed by Johansson and Albrektsson in 1987 [6], is considered as a special advantage in stage 2 surgery, because it represents a definitive clinical verification of initial integration of the dental implant with the bone surface. The torque level required is commonly expressed in Newton centimeters (Ncm) [7, 8].
This way, a clini...
Primary stability has been reestablished as a previous clinical requirement to achieve osseointegration. The presence of movements between the surface of the implant and the bone tissue induces a bone resorption that produces fibrointegration, in which the implant is surrounded by an interphase of soft or connective tissue, and not bone tissue [1, 2].
Strategies used to improve bone response incl...
On bone implantology, stability of a dental implant is an essential clinical tool during osseointegration evaluation, as it is a reflection of the structural and functional connection between the bone and the implant.

Within the limitation of the study, it was concluded that:
The null-hypothesis “superficial and marginal deterioration of M4M and CR would not be significantly different” was accepted.
The M4M (modified 4-META/MMA-TBB resin) and CR (composite resin) combined with a ceramic primer showed comparable characteristics (marginal integrity and wear behavior) in an access hole filling.
The esthetic...
The analysis for the ratio of access-hole with or without marginal staining at the time of T = 12 M showed that the results in group CR (12/16) and in group M4M (12/16) were the same. For this reason, the marginal discrepancy pattern, different in both groups did not influence the aesthetical result. The occlusal contact point (A, B, or C) was compared to the marginal staining rate. Among the...
Focusing on numbers of access-hole showing a disappearance of the overfilling in an early period (up to T = 3 M), groups CR and M4M exhibited 82% (23/28) and 39.3% (11/28), respectively (Table 4). This can be explained by the differences of mechanical properties of both materials. The elastic moduli of M4M and CR are 1.9 and 7.9 MPa, respectively. Flexural strength of M4M is 66 MPa which i...
The in vivo evaluation is quite different from that of the in vitro analysis. In the previous study, all the specimens were calibrated to a flat surface with 2.5 mm diameter. In present study, each access hole had a different dimension and configuration. The filling surfaces were often ø3 to 4 mm in diameter. Access-holes located in the occlusal groove area or in the inclined cusp surface induc...
Nowadays, implant screw-retained prosthesis becomes a popular mode of implant supra-structure restoration. Cement retained implant restoration has issues including irretrievability and difficulty of controlling the cement excess beyond the abutment joint. The cement excess can be a major cause of peri-implantitis [13,14,15]. Screw-retained implant restoration has also some disadvantages including ...
Among the 56 access holes, no filling was dislodged during 12 months, and no complaint was registered from the patients regarding functional and aesthetical aspects.
The results for surface areas changes of access-hole fillings at respective intervals were summarized in Table 3 and Fig. 6. The mean values of the change from T = 1 M to T = 12 M were 77.1 ± 13.1% for group M4M and...
The marginal depth of the access-hole filling at T = 0, T = 1 M, T = 3 M, and T = 6 M could not be defined successfully because of the overfilling phenomenon which disrupted the measurement of marginal gap depth and angle (Fig. 3a–e). Only the marginal depth and angle at T = 12 M could be measured with the same digital microscope, and the mean value for each group was ca...

The retention of implant-supported prostheses is provided by the use of a screw or cement. Recently, it was demonstrated that cement-retained prostheses had a higher rate of technical and biological complications [1], despite a better passive fit than the screw-retained restorations [2]. The CAD/CAM development of the implant-supported prostheses allows a better passively fit with screw-retained p...
Screw retained implant prostheses seem to be an efficient restorative method to prevent peri-implantitis caused by cement excess around the abutment. The drawback of the screw-retained prostheses is the difficulty to realize an efficient access-hole filling functionally and aesthetically. Up to now, few in vitro and in vivo studies were reported in the literature. The aim of this study was to eval...

The root form dental implants which are 3–5 mm in diameter are considered standard diameter implants while less than 3 mm diameter implants are termed mini-implants [1]. Initially, mini-implants were used as a temporary measure, with...
Mini-implants have certain advantages over standard size implants which are being tested in various randomized controlled trials. This systematic review and meta-analysis aims to compare conventional implant overdentures to mini-implant-retained overdentures as regards to patient satisfaction. Electronic databases were searched for eligible studies data required were extracted. The extracted data ...

Within the limitations of this in vitro study, the following conclusions could be drawn:
Implant design, superstructure material, and load direction significantly affect peri-implant microstrains.
The recorded compressive and tensile microstrains for the tested designs were within the physiologic loading range, as they did not exceed the compressive or tensile strength of the bone-implant interf...
Regarding the effect of superstructure material on induced microstrains, generally, different implant designs supporting Lava Ultimate crowns showed higher mean microstrain values(1927.3 ± 1536.6 μɛ), in comparison with those supporting metal crowns (1313.7 ± 973.1 μɛ).Theoretical considerations [44, 45] and in vitro experiments [46,47,48,49] suggest that an occlusal material with ...
Regarding the effect of direction of loading on induced microstrains, it was shown that changing the position of occlusal loading had a considerable effect on the amount of distribution of stresses where axial loading generated even distribution of load around the implant in comparison to off-axial loading where stresses were more pronounced in the area of load application. This might be due to th...
Previous studies have shown that direct correlations exist between microstrain magnitudes and bone stability/instability conditions. This has been summarized by Frost, when bone is loaded below about 2000 microstrains, bone can easily repair what little microdamage occurs. Yet, when pathologic overloading occurs (over 4000 microstrains), stress and strain gradients exceed the physiologic tolerance...
To replace a missing lower molar in compromised ridge, different treatment options were suggested, using either a standard size implant with surgical procedures, short-wide implant, or two mini implants. Concerning the use of mini implant, splinted multiple implants increase the surface area that interfaces with the bone to lessen the per square millimeters of force borne by the bone [11]. The imp...
Results revealed that standard implant showed the statistically significantly highest mean microstrain values (3362.4 ± 757.4 μɛ). Double mini implant showed statistically significantly lower mean microstrain values (801.6 ± 251.4 μɛ), while short-wide implant showed the statistically significantly lowest mean microstrain values (697.6 ± 79.7 μɛ), with a P value
Data were presented as mean and standard deviation (SD) values. Data were explored for normality by checking data distribution and histograms, calculating mean and median values, and finally using Kolmogorov-Smirnov and Shapiro-Wilk tests of normality. Stress data showed non-parametric distribution, so the Kruskal-Wallis test was used to compare between the types of implants. The Mann-Whitney U te...
Each crown was cemented to its corresponding implant-abutment assembly using temporary cement (Cavex Temporary Cement, Cavex, Holland).
Each implant received 4 strain gauges (Kowa strain gages, Japan) placed on the mesial, distal, buccal, and lingual surfaces of the epoxy resin adjacent to the implants. At these selected sites, the thickness of the epoxy resin surrounding each implant was reduced...
In the present study, the following materials were used: titanium root form endosseous implants of standard diameter and length (4-mm platform, 3.8-mm diameter,12-mm length, fixture bevel 0.2 mm, Super Line System, Dentium, USA), short-wide implant (7-mm platform, 5.8-mm diameter, 7-mm length, Super Line System, Dentium, Seoul, Korea) with 1.5-mm machined surface and 5.5-mm threaded surface that ...
There are several factors that affect force magnitudes in peri-implant bone. The application of functional forces induces stresses and strains within the implant prosthesis complex and affect the bone remodeling process around implants [8, 9].
While there are several methods of measuring strain, the most common is with a strain gauge, a device whose electrical resistance varies in proportion to t...
The molars are one of the first teeth to be lost over lifetime; thus, their replacement is frequently needed. Implantation is generally the preferred choice to replace a missing single tooth avoiding vital teeth preparation and bridge fabrication [1].
The mandibular bone loss occurs as knife-edge residual ridge where there is marked narrowing of the labiolingual diameter of the crest of the ridge...
The aim of this study was to evaluate the biomechanical response of the peri-implant bone to standard, short-wide, and double mini implants replacing missing molar supporting either hybrid ceramic crowns (Lava Ultimate restorative) or full-metal crowns under two different loading conditions (axial and off-axial loading) using strain gauge analysis.

We examined clinical parameters in patients receiving long-term implant maintenance. There were significant differences between the H and HP groups in age at the time of maintenance, number of natural teeth at the beginning of implant treatment, total number of extracted teeth, and maintenance. The prevalence of implant-based peri-implantitis was 10.8% of all the implants. All implants with peri-i...
A correlation between the PPD of the peri-implant tissue and lesion progression has been reported, similar to that seen with periodontitis [27]. Probing around the implant is useful for evaluating soft tissue inflammation and is considered reproducible [36]. Examination of peri-implant bleeding is reported to have higher diagnostic accuracy than probing around natural teeth [37]. However, because ...
BoP has been used to evaluate inflammatory conditions of periodontal tissue [33] and can also be an important evaluation item for peri-implant tissues. To avoid diagnosing bleeding resulting from strong probing as a false positive, we set the probing pressure to 0.15 N [34]. BoP values were low, with no significant difference between the groups (H group, 0.30; HP group, 0.28). This result was sim...
All the implants with peri-implantitis came from the HP group, not the H group, thus supporting the view that a history of periodontitis is a risk indicator for peri-implantitis. In the diagnosis of periodontitis within the HP group, it is notable that peri-implantitis increased as periodontitis become more severe. This supports the findings of a previous study that reported that the survival rate...
In this study, we reviewed the clinical parameters of 130 implants in 55 patients during ongoing long-term maintenance. We focused on the history of periodontitis and compared the parameters in two groups classified according to a history of periodontitis. A previous study on the prevalence of periodontitis revealed that moderate or severe periodontitis was observed in 64% of people over 65 years...
Because normality and homoscedasticity were not obtained for each clinical parameter between the two groups, a statistical study was conducted using the nonparametric test (Mann–Whitney U test) for the difference test between the two groups. PPD was recognized to be significantly greater (p
Of the 55 subjects, 25 were male and 30 were female (H group: 8/10, HP group: 17/20, respectively). A total of 130 implants (H group 39, HP group 91) were included in the analysis (Table 2). The mean maintenance period was 6 years and 6 months. The average number of natural teeth at the first visit and at the beginning of implant treatment were 25.3 ± 2.9 and 22.4 ± 4.5, respectively. Com...
At the time of optional maintenance, the following parameters were measured for each implant. Data collection and analysis were conducted by two operators who were blind to the research purpose and methods. One operator statistically analyzed the final data set.
Plaque adhesion (modified Plaque Index: mPI) on the superstructure of the implant was measured on a 4-point scale (0, no plaque; 1, plaq...
This study enrolled 55 patients (25 men, 30 women; mean age, 63.53 ± 10.51 years) who visited Nihon University School of Dentistry Dental Hospital for implant maintenance from April to September 2016. The inclusion criteria were treatment at the same hospital with two-stage implant placement before 2015, and ongoing maintenance at 3–6-month intervals after superstructure placement. Patients ...
Peri-implant diseases are the main biological complication of implant treatment and greatly influence treatment success [1]. Risk indicators for peri-implantitis include a history of periodontitis, poor oral hygiene, and smoking [2,3,4]. Peri-implantitis is often encountered clinically, occurring in 12 to 43% of implants and 28 to 47% of implant patients [5,6,7,8]. Similarities between the patholo...
The pathophysiology and pathology of peri-implantitis remain unclear; however, its similarity to periodontitis has been described. The evaluation of peri-implant tissue and the diagnostic criteria of peri-implant disease are not currently standardized as they are for periodontitis. In this study, we evaluated clinical parameters during the implant maintenance period to determine significant correl...

Bleeding on probing
Plaque index
Pocket probing depth
The oscillating-rotating toothbrush can be used for the plaque and bleeding control around both natural teeth and dental implants. It has also been shown how the toothbrush head designed for dental implant can be effective in plaque removing of the peri-implant tissues.
At the end of the present study, electric toothbrush groups showed plaque and bleeding values lower (PI and BoP on teeth) or at least without significative differences (BoP on implants) than the control group. These data may suggest how the use of electric toothbrush, associated to the dedicate heads, can be an effective method for plaque and bleeding reduction.
This 3-month study aimed to demonstrate the efficacy of an electric toothbrush in reducing plaque and gingival inflammation around dental implants and natural teeth. To better understand the different data collected around two different anatomical structures, we decided to collect data separately. Analyzing our results, it is possible to observe how the mean values for probing, bleeding, and plaqu...

Dental implants became one of the most accepted treatments for the rehabilitation of partial or complete edentulism [1]. However, inflammatory processes may still occur due to the presence of the implant itself [2]. It is well known that peri-mucositis and peri-implantitis are strictly related to the presence of plaque on the surface of the implant-prosthetic complex, which lead respectively to th...
The aim of this randomized clinical trial was to assess the efficacy of an oscillating-rotating toothbrush in reducing plaque and inflammation around dental implants.

The appearance of poorer oral hygiene later in the study also appears to correspond with the drop in follow-up attendance, which again supports the importance of follow-up. All other complications could be resolved and were not persisting. Furthermore, patients selected for inclusion in this study were optimal candidates for dental implants. Though the inclusion criteria predestinate the patient s...
At 5-year follow-up, the overall SBI was 0.32 ± 0.49, reflective of no bleeding given that 0 equals no bleeding and 1 equals isolated bleeding spots visible [27]. The PPD initially decreased within the first 6 months from which point it significantly increased to 2.34 ± 1.18 mm at 5-year follow-up.
Nevertheless, the measured mean PPD still reflects the norm for conventionally placed i...
On the one hand, the variety of bone level changes in this study may be explained by different vertical soft tissue thicknesses, but cannot be validated due to these missing data. On the other hand, there are multiple confounding factors influencing the change in bone level, such as the size of the platform (mismatch), occlusal loading, and the microgap. Additional to the standard success criteria...
Over the 5-year study period, we report
At 3-year follow-up, bone loss was noted in one patient (reclassified as peri-implantitis at the 4-year follow-up) and an important bone loss (due to poor oral hygiene and bruxism; two implants) in a patient with psychosocial issues who could not be treated during the study. Such a patient would not have been included in an RCT.
Consequently, three implants were lost based on the bone loss criter...
Discussion and conclusions
This large, multicenter study provides real-life long-term data on 285 implants placed in 196 patients. The results show that the placement of CAMLOG SCREW-LINE implants with platform-matching or platform-switching abutments results in high survival and success in the long term. The overall success rate for implants was 97.1% at 5-year post-loading, and 97.4% and 96.2...

The primary stability of the implant was assessed during surgery. Implant success and survival were evaluated in the group of implants restored with abutments [5, 29] at both placements of the provisional and definitive prostheses and at each follow-up visit thereafter. Implants were deemed successful in accordance with the criteria for implant success laid down by Albrektsson et al. [30]. Implan...
Assessments
Throughout the study, only radiographs consistent with standard implant procedures were taken. Bone level changes were assessed based on available and evaluable standardized periapical radiographs with a film-holder using parallel-technique or panoramic radiographs (depending on the standard in the study centers). Baseline was defined as the time of the first prosthetic installati...
The treatment indications were single or multiple tooth replacement in the maxilla or mandible without the use of simultaneous augmentation or membrane, of which the implants were to be restored with either fixed single crown or fixed partial denture restorations.

In the present study, CAMLOG SCREW-LINE implants with the Promote plus surface (sandblasted and acid-etched surface) were used. These implants in combination with platform-matching abutments have been shown to have high long-term success rates ranging from 97.8 to 100% at 5-year to 10-year follow-up [9,10,11,12,13]. They can be restored with either platform-matching or platform-switching abutments...
Background
Success and survival rates of endosseous implants are well-documented in a number of controlled clinical trials and systematic reviews [1,2,3]. Generally, controlled trials evaluate endosseous implants in specific clinical situations; thus, the patient population is subjected to rigorous inclusion criteria and follow-up. Accordingly, controlled clinical trials do not reflect th...

Discussion
Dental implants with a reduced diameter are commonly used where bone width is narrow or in cases of restricted mesiodistal anatomy such as laterally maxillary and mandibular incisors. They could also be a viable alternative to bone augmentation especially in challenging situations such as the posterior regions of the mandible. While it has been shown that it is possible to horizo...
Results
Forty-eight patients were screened for eligibility, but six subjects were not included for the following reasons: five patients (10.4%) were hesitant to receive implant treatment, and one patient (2.1%) was treated with intravenous amino-bisphosphonates. Forty-two patients were then considered eligible and were consecutively enrolled in the study. All patients were treated according to ...
Secondary outcome measures were as follows:
Peri-implant marginal bone level changes: evaluated on intraoral radiographs taken with the paralleling technique at implant placement, 6 months and 1 year after loading. All measurements were taken by an independent assessor (LS). Radiographs were scanned, digitized in JPG format, converted to TIFF format with a 600 dpi resolution, and stored in...

Background
Historically, implants have been used and documented mainly with diameters between 3.7 and 4.3 mm. Employing these diameters for numerous indications, scientifically substantiated treatment protocols with excellent long-term results have been established [1].

However, a synergistic effect with other factors is conceivable.

Background
Long-term stable osseointegrated implants are the primary goal in dental implantology. Although dental implants have proven clinical reliable in the long term, the failure of implants at a very early stage of osseointegration has been described. The pursuit to identify the mechanisms leading to early implant failure is ongoing to date and include the following: tobacco usage, diabete...
Abstract
An association between vitamin D deficiency and early dental implant failure is not properly verified, but its role in osteoimmunology is discussed. This article illustrates two case reports with vitamin D deficiency and early implant failure. Prior to implant placement, the first patient received crestal bone grafting with autologous material. Both patients received dental implants fr...

In addition, there was not a significantly less strain site by offset placement. Anitua et al. have reported that offset placement did not affect marginal bone loss around the implant in the oral cavity of the living body. Overloading of the peri-implant bone has been reported to result in bone resorption, and the concentration of considerable stress in the load-side peri-implant bone observ...
Thus, compressed displacement exhibited the same trend in the experimental models and FEA models. The results of both models may be reliable. When the effects of offset placement are considered, there is the concept of the load-supporting area (Fig. 15) put forth by Sato. The load-supporting area is the area surrounded by the lines connecting the implant peripheries, and if a loading point falls w...
In previous studies verifying the usefulness of offset placement, one set of FEA models was created and analyzed by changing the conditions or settings. Few studies used different FEA models with the same placement models. In the present study, we carried out the same experiments with both the models to verify the validity of each analysis.
Moreover, considering the possibility of error while usi...
Strain in the FEA models also exhibited considerable compressive strain on the loading side, similar to the experimental models. In terms of quantitative data for comparison with the experimental models, the length of the places where the strain gauges were applied was measured on the FEA models and the strain was calculated from the length before and after loading and compared with the expe...
Discussion
Experimental models
Reported studies verifying the effects of offset placement include ones where implant bodies were embedded in rectangular experimental models, ones where rectangular bone models were constructed with FEA models, and ones where FEA models were constructed from CT data on human mandibles. The artificial mandible models used in the present study were type II in the ...

A strain gauge (2630-100, Instron Japan, Kanagawa, Japan) was attached between the worktable and jig, and the change in the distance between the worktable and jig was measured under the assumption that it would be the same as the implant displacements under loading conditions (Fig. 6). Measurements were taken five times at each loading site, and the mean of the five measurements was considered the...
FEA software (Mechanical Finder®, Research Center of Computational Mechanics, Tokyo, Japan) was used to construct three-dimensional FEA models from the resulting CT data. The mesh was constructed of tetrahedral elements, and the total numbers of nodes and elements were approximately 260,000 and 1,400,000, respectively. FEA models were prepared with appropriate physical properties (Table 1) determ...
Preparation of the superstructure
Using the anatomical crown width as a reference, it was determined that the occlusal surface view of the superstructure would be trapezoidal with a 7-mm buccolingual width in the mesial first premolar section, a 10-mm buccolingual width in the distal first molar section, and a 26-mm mesiodistal width (Fig. 4). The vertical dimension was 8 mm; the upper 4 mm was t...

Background
Bone remodeling to maintain osseointegration between the bone and implant is absolutely essential to ensure favorable results and long-term stability in implant treatment. Bone remodeling requires that various stresses generated around the bone caused by the occlusal load applied to the implant be within an appropriate range. The concentration of stress at the bone-implant interface,...

This survey served to clarify the current status of implant prosthodontics, issues, and considerations in their fabrication, and the status of prosthetic complications and preventive initiatives, all from a laboratory perspective.
Concerning implant treatment, it was concluded that dentists either play the leading role or work in collaboration with technicians, inc...
While the literature includes reports of frequent IOD-related prosthetic complications such as attachment-related compromised retention, detachment or fracturing of denture teeth, relining, and attachment damage, this survey showed a somewhat different trend. It can be inferred that these results differ from actual complication trends because they constitute responses to cases sent to ...
The questionnaire revealed several creative steps, based on laboratory considerations, being taken to prevent veneer chipping and fractures, a frequent and problematic prosthetic complication (Q12) (Figure 7). Technicians were taking into account metal (including zirconia) coping designs (36.3%), covering only the distal-most part of the molar region with metal (24%), using veneering composi...
Looking at repair requests (i.e., complications) involving the superstructures of fixed implant prostheses (Q11) (Figure 6), facing damage and chipping accounted for more than half of all requests (54.5%). Generally speaking, there are many reports that indicate a high incidence of complications related to fixed prostheses involving abutment screw loosening, detachment of cement-retained cro...
This number was lower than in any of the other nine countries, and future changes in IOD use in Japan are a topic that remains interesting.

According to Papaspyridakos et al., indicators such as implant level (the relationship between the implant and bone) and the state of soft tissue around the implant are the most frequently used indices of implant s...
There is also a greater possibility of direct (in-mouth) repair of failed veneering materials and greater shock-absorbing potential relative to occlusal force in comparison with porcelain. The trend to adhere resin materials instead of porcelain, from Brånemark and colleagues’ recommendations for acrylic resin as an occlusal surface material in the early 1980s, also cannot be ignored. All...
There is a low risk of facing damage and chipping for prostheses in the anterior region. Nonetheless, the questionnaire revealed the unexpected result that indirect composite facing crowns accounted for 21.3% of the total. This may be because there are many indirect composite resins (Estenia, Ceramage, etc.) available in Japan, and crowns and bridges in the anterior region (natural abutment ...
Our questionnaire indicated a distribution of 61.4% cement-retained versus 38.6% screw-retained prostheses (Q3), suggesting that cement retention is used more frequently in Japan. Unfortunately, the fabrication-oriented focus of this survey prevented clarification of the types of cement used for cement retention and the breakdown between provisional and definitive cement.

Background
Currently, dental implant treatment is evaluated on the basis not only of restoring masticatory function, but also a variety of other factors, including the implant and superstructure survival rate and psychological impacts. Numerous factors must be taken into account, to offer highly predictable implant treatment, and there is no doubt that prosthetic-related factors such as the typ...

Conclusion
Titanium is used in many fields in addition to being used in dental implants. As the use of titanium increases, concerns over safety are increasing as well. In recent years, studies with regard to titanium toxicity have been on the rise. Although they have mainly been focused on environmental and basic fields, studies are now expanding into the medical field. Thus, there is a need fo...
Alternative methods of implant materials are under investigation for the risk of titanium. Typically, these include zirconia and polyetheretherketone (PEEK) dental implants. These materials are considered to be alternatives to the hypersensitivity of titanium and are aimed at improving esthetics. Currently, zirconia is a clinically applied material for dental implants. There have been many s...
The next issue involves looking at the potential threats of titanium. Titanium is currently used in a wide range of fields. As such, there are many studies with regard to environment safety in the field and basic science. Such titanium is primarily used as titanium oxide nanoparticles. Animal experiments, especially in rodents, are being conducted to study the effects of titanium oxide nanop...
Titanium is known to yield fewer allergic reactions than other metals such as nickel and palladium. However, as mentioned in the "Results" section, titanium allergy symptoms have been reported in some cases. These symptoms can occur systemically with inflammation of the mouth, erythema, etc. Therefore, any history or suspicion of a titanium allergy would be considered prior to dental implan...
The absorbed titanium can accumulate in other organs in the body as shown in the animal and cultured cell experiments. In addition, Feng et al. reported that nanoparticles can pass through the blood-brain barrier (BBB) and may be toxic to the central nervous system (CNS). The testing methods still have limitation and further studies need to be performed, but the neurotoxic nanoparticles incl...
This is defined as a tribosystem which has three interrelated components: tribology (friction, wear, and lubrication), corrosion (material and environmental factors), and biochemistry (interactions between cells and protein). The wear and corrosion in the contacting surface of implant fixture and implant abutment can cause the failure of dental implant system, and the wear debris and metalli...
Discussion
Titanium is presently used in a variety of applications including dental implants, orthopedic prostheses, industrial cosmetics, drugs, confections, and paints. Due to its extensive usage, issues related to stability need to be discussed. Titanium dental implants possess many advantages and are now widely used with high rates of success. However, we need to look at the aforementio...
There are numerous reports showing the association between titanium and yellow nail syndrome in addition to the above reports. In 2015, Decker et al. reported a case of a 67-year-old female patient who had lost her claws 18 months prior and had changes in bronchitis, sinusitis, and nails within the last 5 years. Inhaled corticosteroids were used for initial continuous cough symptoms but were no...
At least 10 of 20 patients were reported to show an improvement in symptoms after 6 months of continuous vitamin E1 administration at 200 IU/day; however, there was a continuous debate regarding the medication details.
Efforts to elucidate the pathogenesis of yellow nail syndrome are currently underway. In 2001, D’Alessandro et al. reported that the protein content of pleural effusions was...
Titanium-related diseases
It has been reported that systemic disease can occur due to titanium. According to a study by Berglund and Carlmark in 2011, titanium can be attributed to the cause of “yellow nail syndrome.” In 30 patients with yellow nail syndrome, energy-dispersive X-ray fluorescence (EDXRF) was used to measure the titanium content in the nails of patients; the titanium content w...
All metal prostheses except the implant screw and abutment were removed, and the eczema reaction was reduced to 30%; the symptoms still remained. The removal of the titanium implant screw and abutment in 2014 led to a full recovery. In Korea, allergy condition has also been reported after the installation of titanium implants. In 2012, a 70-year-old woman exhibited a stomatitis that appeared to be...
They are the releasing due to the friction between implant and bone surface during installation, the wear during debridement at maintenance visits, and the corrosion. Fretwurst et al. reported the metal particle in peri-implant soft tissue along with M1 macrophages and the increasing in titanium concentration with lymphocytes detection. In association with the metal particle releasing, the damage ...
Recently, there are more studies working on the linking of titanium implants and implant complication or failure. Wachi et al. reported that Ti ions may be involved in the deteriorating effects of peri-implant mucositis, which can develop into peri-implantitis accompanied by alveolar bone resorption. Olmedo et al. reported two cases of reactive lesions of peri-implant mucosa associated with titani...
Maritini et al. compared implantation of titanium powder plasma-spray-coated titanium screws (TPS-Ti) and fluorohydroxyapatite-coated titanium screws (FHA-Ti). Authors reported the evidence of titanium dispersion inside the medullary spaces when TPS-Ti was implanted, which was the result of friction occurring at the implant surface-host bone interface, leading to loss of integration in the coating...
In the presence of both H2O2 and albumin, there was a very much higher rate of metal release from Ti6Al4V compared to the presence of albumin and H2O2 alone. Furthermore, in a recent study, Zhang et al. continuously worked on the synergistic effect of albumin and H2O2 on corrosion of Ti6Al4V in physiological saline with electrochemical method and showed the time-dependent dissolution of Ti6Al4V. ...
In 1993, Haynes et al. performed experiments using titanium-aluminum-vanadium (Ti-Al-V) and cobalt-chromium (Co-Cr) particles of similar size range and concentration similar to those found in failed hip prostheses. In the abdominal macrophage experiments of rats, Co-Cr yielded a high toxic response while Ti-Al-V increased the release of inflammation-inducing mediators such as prostaglandin E2, int...
The interaction between TiO2-NP and inflammatory cytokines, including CXCL8, a clinically relevant pro-inflammatory chemokine, was also investigated by Batt et al.. The authors found that the TiO2-NP could preferentially adsorb CXCL8 (and IFN-γ), which leads to the disruption of neutrophil chemotaxis and modifies local inflammatory mediator concentration and might result in hampered inflammatory ...
Recently, Kim et al. reported an in vitro experiment regarding the expression of mucin genes in human airway epithelial cells. The authors confirmed that TiO2-NP initiated the TLR4-dependent pathway, leading to the MUC5B overproduction, which relates to the inflammatory response in human airway. In Suarez-Lopez del Amo et al. experiment, the TiO2 particles derived following implantation were colle...
Valentini et al. investigated the toxicity of TiO2-NP to the cortical neuron cultures and in the brain of rats, reported the clear impact of TiO2-NP on the neuronal cells and rat brain, and indicated the new evidences of TiO2-NP toxicity in CNS.
While there have been reports of titanium toxicity in animal models, Fabian et al. and Warheit et al. reported that the risk of titanium toxicity was no...
The toxicity of TiO2 (titanium dioxide) nanoparticles (TiO2-NP) in rodents has been reported. Many authors studied the serum biochemical parameters, pathology changes, and the biodistribution of TiO2-NP in the liver, kidneys, lung, spleen, and brain tissue by facilitating a variety of methods including blood biomarker assays, histopathological examination, etc. The dependence of experiment results...

Background
Titanium is one of the most widely used materials for dental implants due to its mechanical strength, biocompatibility, and a long history of use. Current titanium dental implants possess a high success rate; however, failures are still being reported. Cause of these implant failures can be poor oral hygiene, uncontrolled deposition of plaque, and calculus around the implant which ca...
Abstract
Background
Titanium is a commonly used inert bio-implant material within the medical and dental fields. Although the use of titanium is thought to be safe with a high success rate, in some cases, there are rare reports of problems caused by titanium. In most of these problematic reports, only individual reports are dominant and comprehensive reporting has not been performed. This comp...

Conclusions
Within the limitation of the present study, it can be concluded that the restoration design affected the failure load of ceramics. Monolithic design had a statistically significant effect on the failure load of two different ceramics (LDS > ZLS). Veneer application had opposite effects on two different ceramics which increased the failure load of ZLS and reduced it for LDS witho...
Zheng et al. compared the stress distribution of the same veneering ceramic on different cores and concluded that the zirconia core was clearly different from other materials with higher tensile stresses at the veneer core interface because the increasing differences between the elasticity modulus of the core and the veneer transmitted higher stress concentrations to the cores. Con...
Veneer application provided additional strength to the ZLS crowns in contrast to the LDS crowns. The higher failure load of the veneered ZLS crowns (2202.55 N; group L-V 2077.37 N) may be associated with the higher flexural strength of the veneering porcelain VM-11 (100 MPa; emax Ceram 90 MPa). These veneered groups had a statistically significant difference from the monoli...
Similar results were presented in a study of Traini et al. as it was concluded that ZLS was comparable to that of existing zirconia-based ceramics and was suitable for oral function even in the posterior regions. In the literature, there have been few studies on this ceramic and a limited number of them include the failure load of the material. In one of these studi...
In literature, it has been stated that the failure load of LDS crowns was higher than veneered zirconia and could be comparable with metal ceramic systems. Doğan et al. evaluated the fracture strength of different CAD/CAM-manufactured crowns and concluded that the monolithic LDS crowns had the highest fracture resistance. Present study confirmed as monolithic LDS crowns demonstrated so satisfying...
Discussion
Implant-supported restorations have been accepted as an alternative treatment for the rehabilitation of edentulous spaces. Despite the high success rates, implant failures are inevitable and classified as early or late implant failures. Late implant failures are observed after prosthetic restoration which is primarily related to biomechanical complications. Since occlusal loads are t...
Results
Descriptive analysis (mean, standard deviation (SD), minimum, maximum) of the groups is presented in Table 4.
Group L-M exhibited the highest failure load values (2891.88 N ± 410.12 N), and the lowest values were observed in group ZL-M (1750.28 N ± 314.96 N). Two-way ANOVA indicated a statistically significant difference between materials and veneering technique (p = 0.00 < ...
Statistical analysis
The statistical analysis was performed with SPSS 24.0 (SPSS Inc, Chicago, USA). The Kolmogorov–Smirnov normality test was used to evaluate whether the data distribution of the groups was normal. The homogeneity of the variances was analyzed by Levene’s test. Since test results indicated that data distribution of the groups was normal and the variances were homogenous,...
All crowns were subjected to a combination firing that included crystallization and glaze firing according to each manufacturer’s guidelines in the ceramic furnace (Vita Vacumat 6000 M, Vita Zahnfabrik, Bad Sackingen, Germany).
For veneered restorations, the design mode was changed to “split,” and the core was constructed in 0.6-mm thickness. In group L-V (n = 12), e.max ...

Background
Implants have been successfully used to replace missing teeth for many years. Notwithstanding the high success rates, complications such as screw loosening and/or fracture, prosthesis fracture, and even implant fracture are inevitable. The reasons of the complication may be related to decreased proprioception and low tactile sensitivity which makes implant-supported crowns more susc...
