Thus, this study has examined the possibility of activating an alteration surface in tantalum using the anodizing process, which is effective in other metals like titanium. From our findings, it was possible to develop time exposure protocols in order to obtain conductive surface alterations similar to those already available from some of the largest manufacturers of oral implants. Scanning electr...
The search for new biomaterials and biocompatible metals has always been a common objective of human rehabilitation research centers. In implant dentistry, titanium has successfully established itself as the material of choice for dental implants. However, several studies have reported cases of metal allergy caused by titanium-containing materials [15–17] and some immune dysfunctions in certain ...
Tables 2 and 3 show similar rates among the chemical elements present on the non-treated tantalum surface—group 1 (Fig. 5). In Tables 4 and 5 (group 2), calcium (Ca) is included. The rates for the other chemical elements are similar to the rates in group 1 (Fig. 6). In Tables 6 and 7, group 3 sample shows the basic chemicals present in previous groups and similar rates (Fig. 7). Two chemic...
The analysis of the images obtained by scanning electron microscopy confirmed the changes on the surface of tantalum strips according to different exposure times. In Fig. 1, we can observe Ta surface with grooves resulting from the machining of the metal with no surface treatment. As the magnitude increases, the image shows the lines pattern with its peculiar characteristics from the manufacturin...
Within a 50-mL tank, the electrolytic solution as described above received a voltage variation of 160 V initial tension at zero time and a final tension at the preset end-time for each group of samples. There was a gradual increase in voltage due to the maintenance of a fairly constant current at around 0.15 to 0.25 A. The electrolytic solution was periodically changed to prevent solution satura...
We used 60 strip-shaped samples of tantalum with the following dimensions: 7 mm wide, 11 mm long, and 0.01 mm thick (Kurt J. Lesker Company—USA, 99.95 % purity). The samples were washed in distilled water and placed in an ultrasonic tank containing acetone (Ultra Sonic-1440 Plus—Odontobrás, Ribeirão Preto/SP, Brazil) to remove residues. Then, they were divided into four groups: in group ...
In this way and following the successful results already obtained with Titanium, this study aimed to develop an oxidized surface layer on Tantalum samples and, subsequently, analyze the samples’ topography and levels of salt deposition using an electronic microscope.
The use of materials that come into direct contact with human tissues such as the bone requires maximum biological security. These materials remain for a long period of time or even indefinitely in the human body, and no negative reactions, like toxicity or carcinogenic effects, shall be acceptable.
For this reason, biocompatibility of new materials has been widely studied, and only after a lot o...
Search for materials that may either replace titanium dental implants or constitute an alternative as a new dental implant material has been widely studied. As well, the search for optimum biocompatible metal surfaces remains crucial. So, the aim of this work is to develop an oxidized surface layer on tantalum using plasma electrolytic oxidation (PEO) similar to those existing on oral implants bee...

The electro-chemical method can be employed for HA-Zn coating deposition on titanium metal, where Ca source was a recycled cuttlebone fish to precipitate HA phases. Using a Zn anode on a low-sustained voltage was able to induce an even coat thickness of HA-Zn precipitation and increase the surface roughness significantly.
Yang et al. prepared a Zn-HA coating on Ti plates by an electrochemical process, and the SEM examination showed irregularly shaped rod-like crystals with hexagonal cross-section; this corresponded well with the current study results. They also concluded that a Zn-HA coating improves proliferation and differentiation of osteoblasts and would enhance implant osseointegration [11].

Metallic orthopedic prosthesis is most commonly used due to its good mechanical properties, but its failure mostly occurs due to the lack of proper bone bonding and/or the occurrence of post-operative infections. Hydroxyapatite is commonly used as a bone filler biomaterial or as a coat for titanium prosthesis due to its decent biocompatibility, osseoconductivity, and bioactivity [26]. However, as ...

The current retrospective consecutive case series study provides preliminary data that treatment with 7-mm-length short implants with a hydrophilic electrowetted surface is a reasonable approach in sites with limited vertical bone dimension. It adds to the body of evidence supporting short implant use for compromised sites. The success seen might be attributed to the larger implant diameters that ...
Thirty-six percent of the implants in the study were placed in extraction sockets. Provided that sufficient initial implant stability is achieved, there should be no additional risk factors compared to implants in healed sites. Studies have shown no difference in marginal bone remodeling between immediately placed and delayed implants [15].
The biggest limitation of the current study is its very ...
A wide distribution in implant insertion torque (10–50 Ncm) was seen in the study. This reflects the variety of clinical situations in which the implants were placed. Assessments were made by using both the RFA value and the insertion torque as to first whether an implant should have been left to heal in the first place and if so, how this would be best accomplished, i.e., through its submergen...
This retrospective study is the first to look at short dental implants with a hydrophilic electrowetted surface. The survival data suggest that this treatment is a viable option to care. In a systematic review that identified 13 studies on implants shorter than 10 mm, the CSR from the individual studies ranged from 80 to 100% with a combined CSR of 98.3% after 5 years, 94.8% after 6 years, and ...

The main study parameters (principal outcome parameters) were defined to be implant loss and follow-up time. The cumulative survival rate was estimated. The influence of several factors on ...
A retrospective study on short 7 mm hydrophilic implants from a single center was conducted in a private practice limited to periodontics and surgical dental implant placements from one of the authors, PSR (Yardley, Pennsylvania, USA).

The aim of this retrospective consecutive case series study was to investigate implant survival rate and analyze possible factors affecting the survival of short implants placed in one surgical practice focused on implantology and periodontology in a temporal cohort.
In the past decades, the osseointegration rate of dental implants has dramatically increased, particularly in sites of softer dental bone, which may be attributed to the introduction of moderately roughened surfaces [1, 2]. Moreover, because of this increase in success, clinicians have attempted to push the envelope and place implants into sites that may provide a greater challenge as they wish to...

In normal blood samples composed of light yellow plasma, spectrophotometric determination of platelet counts would be useful for quality assurance of individual PRP preparations. For accurate determination, however, operators should handle samples with care to minimize the inclusion of WBCs and RBCs in PRP preparations.
Consistent with the clinical significance of platelet counting, several studies have reported that the platelet concentration is the most reliable criterion for the regenerative ability of PRP [27, 28] because platelets increase the number of anabolic signaling molecules. Conversely, as WBCs increase the number of catabolic signaling molecules, the quality of PRP can, perhaps, be considerably alte...
Another limitation is the color of plasma. In terms of color, blood samples obtained from the donors participating in this study were light yellow and could be evaluated as “normal.” However, we have sometimes encountered colored plasma samples in clinical practice. For example, when blood triglyceride levels are high, the plasma turns milky white or turbid [22,23,24]. Hemolytic plasma looks r...
Since determination of bacterial cell number is a fundamental procedure in the field of microbiology, several methods have been developed and widely employed depending on the purpose of cell counting. SPM is one of the common methods used to estimate bacterial load [12]. The advantage of SPM is speed and convenience without additional preparation steps. On the other hand, the limitations are the i...
For validation of these calibration curves, P-PRP and L-PRP preparations prepared by three independent operators were employed. Blood cell counts are shown in Fig. 5. As observed in the calibration curves for the samples, significant differences were found in WBC and RBC counts, but not in platelet counts, between the P-PRP and L-PRP preparations. Correlations between platelet counts and WBC or R...
The appearance of the blood-collection tube after the first low-speed spin and representative P-PRP and L-PRP preparations after the second high-speed spin and subsequent re-suspension are shown in Fig. 2.

Using the data obtained with both the AHA and SPM, scattered plots were created to examine correlations and obtain formulas to calculate platelet counts.
P-PRP and L-PRP preparations were independently prepared from the 11 donors by three well-trained operators. Platelet counts were first determined using the AHA and aliquots of the PRP preparations were measured using the SPM. Platelet counts we...

In this study, we focused on the possibility of spectrophotometric determination and validated the applicability of the proposed method on platelet counts in PRP preparations. This idea was based on bacterial cell counting [12] and a similar challenge was reported in 1992 [13]. However, this optical method has not been further modified for PRP as a grafting material for regenerative therapy in acc...
Almost two decades have passed since platelet concentrates, such as platelet-rich plasma (PRP), were first introduced to the field of regenerative medicine by Marx et al. [1]. To date, PRP has been modified to create different variations and has increasingly been used in various fields of regenerative therapy around the world. However, negative data obtained from clinical applications of PRP have ...
Platelet-rich plasma (PRP) is widely used in regenerative dentistry and other medical fields. However, its effectiveness has often been questioned. For better evaluation, the quality of individual PRP preparations should be assured prior to use. We proposed a spectrophotometric method for determination of platelet counts and validated its applicability using two types of PRP preparations.

The current retrospective consecutive case series study provides preliminary data that treatment with 7-mm-length short implants with a hydrophilic electrowetted surface is a reasonable approach in sites with limited vertical bone dimension. It adds to the body of evidence supporting short implant use for compromised sites. The success seen might be attributed to the larger implant diameters that ...
Thirty-six percent of the implants in the study were placed in extraction sockets. Provided that sufficient initial implant stability is achieved, there should be no additional risk factors compared to implants in healed sites. Studies have shown no difference in marginal bone remodeling between immediately placed and delayed implants [15].
The biggest limitation of the current study is its very ...
A wide distribution in implant insertion torque (10–50 Ncm) was seen in the study. This reflects the variety of clinical situations in which the implants were placed. Assessments were made by using both the RFA value and the insertion torque as to first whether an implant should have been left to heal in the first place and if so, how this would be best accomplished, i.e., through its submergen...

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...

Although EDS analysis was performed in three areas on each sample, the atomic percentage of carbon on the contaminated area was higher than that on the clean area and the atomic percentage of titanium was lower on the contaminated areas than on the clean area except cathodic potential 1 A and 1.5 A in group III. The possible sources of carbon conta...
According to the previous studies, complete killing of bacteria was seen at anode with low current. However, in this study, complete removal of contaminant was seen in electrolysis after cathodic potential 1 A and 1.5 A in group III. This complete removing action can be attributed to the alkaline environment generated at cathodic potential. Moreover, decrease in electro...
However, copper deposition was formed on the sample after electrolysis of anodic potential in group II. It is believed that anodic current was preferentially supplied by the electrolysis of water, which occurred on the surface of the sample because deposition attained electroconductivity. Thus, it was confirmed that copper could be incorporated into the titanium surface sample, t...
Previous studies also pointed out that low direct current can kill oral bacteria forming in biofilm. Although charging the implant surface with current can kill the bacteria, organic residues still remain adhering on the surface. Infected implants present carbon-based contaminants and considerable changes in titanium surfaces composition even after sterilization. This could be the reas...
Therefore, in this study, phloxine B staining was used to detect residual contamination on the surface of the healing abutments.

Discussion
The current study showed that electrolysis could be an effective means to decontaminate the healing abutment surfaces with complete removal of contaminants without any surface changes at 10 V, 1 A into 5 min, cathodic potential in group III. A minimally invasive approach to remove and disinfect dental implants utilizes the fact that titanium is an electrically conducting me...
Analysis of healing abutment surface roughness after electrolysis
Representative SEM images after electrolysis of two different charges (cathodic and anodic) and two different currents (1 A and 1.5 A) are presented in Fig. 3. The SEM images showed surface modification ranging from smoothening to roughening. The surfaces were between the electrolytic healing abutments and control unused healin...
Results
Analysis of the electrolytes’ pH before and after electrolysis
As shown in Table 1, pH of electrolyte (catholyte) was not changed after electrolysis of different currents. However, the pH decreased after electrolysis of anodic potential of 1 A and 1.5 A in group I and II.

Ninety healing abutments removed from patients at the Dental Implant Clinic, Dental Hospital, Tokyo Medical and Dental University, were used. As this clinical study is an in vitro experimental study, the university ethical committee decided that ethical approval was not necessary.
These healing abutments were at least for 4 weeks up to 6 weeks in patients’ oral cavities. All the healing abu...
Background
A healing abutment is a small metal cap placed on the dental implant. In dental implant treatment, a healing abutment is first placed on the implant. The top of the healing abutment is exposed in the oral cavity, while its body penetrates the soft mucosal tissue. During the implant treatment, the healing abutment is temporarily removed and replaced into several times until the prosth...
