The results of the present case series study should be interpreted in a critical light because of the small study population. However, it can be concluded that periodontally diseased subjects treated in a supportive periodontal therapy can be successfully rehabilitated with oxide-coated dental implants for a follow-up period of 3 to 6 years. The results suggest that implants in the maxilla and in...
These results from long-term clinical studies indicate that oxide-coated implants achieve equivalent survival rates and prevalence of mucositis and peri-implantitis when compared to implants with other surface characteristics. They support the assumption that the implant surface has little influence on the development of mucositis or peri-implantitis. This was subsequently confirmed in a Cochrane ...
The present study examines the success rates of oxide-coated implants in subjects with treated periodontal disease. Several long-term clinical studies on periodontally healthy subjects have revealed survival rates of 97.1 to 99.2% for oxide-coated implants [10, 24, 25]. The results of the present study show a comparable implant survival rate (96.2% in GAP and 97.1% in GCP subjects) for subjects wi...

The univariate analyses showed a significantly higher risk for peri-implantitis in GAP subjects (OR = 3.294 with p = 0.027) and at implants with bone quality grade 3 (OR = 21.200 with p = 0.000). However, these differences were not significant in multivariate analyses.
Both the uni- and multivariate patient-related analyses were non-significant.

All 29 subjects were examined over the period of 3 to 6 years (Table 2). For the duration of the observation period, all the remaining teeth were periodontally healthy, with PDs ≤ 3 mm and negative BOP. All subjects were non-smokers, had excellent oral hygiene, attended the follow-up examinations on a regular basis, and had no systemic disease.
In total, four implants (3.1%) were lost du...
Peri-implant mucositis was defined as PDs ≥ 5 mm with BOP and no bone loss after the first year of loading. Peri-implantitis was defined as PDs > 5 mm with or without BOP and an annual bone loss of > 0.2 mm after the first year of loading.
All technical and surgical complications (e.g., fracture of the abutment screw or superstructure, compromised wound healing) were recorded.

All patients received a supportive periodontal therapy at the Dental School of Medicine, Philipps-University, Marburg, in the course of the observation period. The first clinical examination was 2 to 4 weeks before the non-retainable teeth were extracted. The periodontally healthy residual dentition and the implants were evaluated immediately after the superstructure was inserted. Subsequently, t...
Second-stage surgery was performed in the maxilla after 6 months and in the mandible after 3 months. Implant placement and second-stage surgery were performed by a single periodontist (R.M.).
About 4 weeks after the final abutments were placed, GCP subjects were rehabilitated with single crowns, implant-supported bridges, or removable superstructures, according to the Marburg double crown syst...
A total of 29 partially edentulous subjects were consecutively recruited from the Dental School of Medicine, Philipps-University, Marburg, Germany between April 2010 and April 2013 (Table 1). Subjects were excluded for the following reasons: history of systemic disease (e.g., cardiovascular diseases, diabetes mellitus, osteoporosis), pregnancy, untreated caries, current orthodontic treatment, con...
The aim of this long-term clinical study on partially edentulous subjects treated for periodontal disease was to evaluate the prevalence of mucositis and peri-implantitis and to determine the survival and success rates of dental implants with oxide-coated surfaces.
In recent years, a great number of different implant systems varying in materials, surface structure, and macroscopic design have been introduced to the dental market [1]. In studies using implants with modified surfaces, it was concluded that rough surfaces induce a stronger initial bone response, achieve stability more rapidly, and integrate more fully with extant bone [2,3,4,5,6]. Dental implan...
The aim of this case-series study is to evaluate the prevalence of mucositis, peri-implantitis, and survival and success rates of oxide-coated implants in subjects treated for periodontitis.

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 chart review identified 86 placed implants in 75 patients. Table 1 summarizes the patient demographics of the 75 patients. Patients ranged in age from 29 to 88 years with a mean of 61.0 ± 12.5 years. Twenty-seven of the patients were males and 48 were females. Table 2 summarizes the implant and site-related information of the 86 placed implants. Mean insertion torque was 30.1 ± 7...
Baseline parameters, both patient- and implant-related, as well as follow-up parameters (implant survival, follow-up time, and resonance frequency analysis) were collected from a review of the patient records.
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). An exhaustive chart review identified 75 patients for analysis that were treated with 86 short (7 mm) implants during a 5-year period (September 1, 2009, to Novem...
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...
This retrospective consecutive case series study was performed to determinate the survival rate and implant stability of short (7 mm length) dental implants with an electrowetted hydrophilic surface that were in function from 1 to 7 years.

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...
This retrospective consecutive case series study was performed to determinate the survival rate and implant stability of short (7 mm length) dental implants with an electrowetted hydrophilic surface that were in function from 1 to 7 years.
A retrospective chart review identified and evaluated 86 consecutively placed 7-mm-long dental implants (ProActive, Neoss Ltd., Harrogate, England) in 75 pat...

In addition, Buch et al. compared the different criteria proposed for implant success with regard to their clinical value. The authors demonstrated that the proposed criteria led to very different success rates 6 years after implant insertion (75–89%) and did not allow reliable comparison of the results with each other. Thus, during control visits in our practices, only prosthetic complica...
The most often used graft material in our evaluation was Geistlich Bio-Oss (53.0%) followed by autogenous bone (32.5%). When compared to no graft, the use of both grafts resulted in significantly higher implant survival rates. In various studies, the bone substitute was found to promote bone regeneration and to allow for long-term stability of the augmented volume. A recent meta-analysis com...
However, there are also a few clinical studies in which reduced survival rates for implants inserted in grafted areas were found. Differences in numbers of implants analysed, surgical techniques, indications and/or graft materials may account for these inconsistent results and further studies might be needed.
In the retrospective analysis shown here, the comparison of different augmentation...
Discussion
The retrospective analysis presented here evaluates implants inserted in three different private practices with or without augmentation procedures. Treatments were performed according to the standard protocols applied in the private practices. More than 10,000 implants were inserted in various indications and were followed up to 20.2 years from the day of implant insertion. The o...
When looking into the Kaplan-Meier implant survival curves of the augmentation procedures using the log-rank test, the highest implant survival was found for bone condensing followed by lateral augmentation, internal sinus lift, transplantation of bone blocks, bone splitting/spreading, titanium mesh, external sinus lift (one- and two-step) and finally, no augmentation. This sequence was statistica...
Results
Of the 10,158 implants, 58.2% (5916 implants) were inserted using an augmentation procedure. The minimal observation period until the last control visit or until explantation was 0 days (day of implantation); the maximum period was 20.2 years. Distribution of analysed implants according to the period of observation is shown in Table 1.

Methods
The retrospective analysis evaluates patients who underwent implant therapy with or without accompanying augmentation procedures between August 1991 and December 2011 in three private practices. Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines were followed. To investigate the effect of the different techniques applied on implant survival without ...
Background
Replacing missing teeth with dental implants is a routine treatment in many dental practices. In order to achieve adequate functional and aesthetic results, an optimal three-dimensional implant position has to be assured. Various materials are available to build up missing bone. While autogenous bone is usually regarded to be the gold standard, harvesting may be associated with morbi...

Abstract
Background
A sufficient amount of bone is essential to ensure long-term stability of dental implants. To support the bone regeneration process, different techniques and materials are available. It has been questioned whether these techniques and materials...

CONCLUSIONS
Peri‐implantitis began to appear more frequently after the fifth year of functional loading, with a peak of incidence observed after the seventh year, especially between the seventh and eighth years. The incidence of peri‐implantitis increased when the data were analyzed from the fifth year to 10 years of function. Consequently, studies that consider a follow‐up period
The rate of peri‐implantitis observed in this study at 10 years, agreed with that described by Bragger et al. and Karoussis et al. in which peri‐implantitis occurred in 15.4% of the implants after a mean observation period of 10 years. Simonis et al. (2010) reported a prevalence of 16.9% of peri‐implantitis after an observation period of 10 to 16 years.
The study of de Waal et al. desc...
During the interval between the sixth and seventh year of functional loading, a slightly higher rate of failures than that in the previous years was observed.
The ratio between the rate of peri‐implant complications and the time of function was even more evident for peri‐implantitis, which showed a significant increase after the seventh year of functional loading, with a more evident increase...
The aim of this retrospective study was to assess the survival and success rates as well as the incidence of peri‐implantitis in patients with a history of periodontitis who followed an individual maintenance program and supportive periodontal and peri‐implant treatment (SPT), and with 1 to 10 years of implant functional loading.
The results obtained in the present study show that peri‐impl...
A total of 1,991 implants (475 patients) with 10 years of functional loading met the inclusion criteria and were included in this study: 90 patients were totally edentulous (559 implants), 155 patients were partially edentulous (732 implants), and 230 patients were mono‐edentulous (700 implants) (Tables 1 and 2).
Table 3 shows the life table analysis and cumulative survival and success rate and...
When a two‐stage technique was performed (i.e., sinus floor augmentation without implant insertion or staged‐approach GBR), a healing period of at least 6 months was observed before implant insertion. The implants were functionally loaded after 3 to 6 months of the implant placement.
2.3.3 Follow‐up
After surgery, for a maintenance program, all patients followed an individual SPT. The ...
Where a deficient posterior alveolar ridge and increased pneumatization of the maxillary sinus appeared, implants were inserted with simultaneous sinus floor augmentation (one‐step procedure) (osteotome technique, or lateral window technique) or after a previous sinus floor augmentation with bone grafting (two‐step procedure).
Sites that exhibited localized horizontal bone...
Successful tissue integration was examined using predefined criteria of success, as follows:
Absence of persistent subjective complaints, such as pain, foreign body sensation and/or dysesthesia.
Absence of implant mobility.
Absence of continuous radiolucency around the implant.
Implant prosthesis functional loading ≥1 year.
Absence of exude or suppuration at acupressure o...
2.2 Clinical parameters
Periodical clinical examinations assessed before treatment and during follow‐up were recorded. Clinical parameters at baseline and after prosthesis positioning were used as a reference of development of peri‐implant disease.
Based on the suggestion of Mombelli and Lang, and confirmed by the successive EWP consensus workshops published in 2008, 2011, and 2012, peri...
This is a retrospective cohort study started from the analysis of clinical records of patients referring to private dental practices in central Italy (AP) treated between February 1998 and December 2002 by three different operators, and then included into a follow‐up program. We followed the Strengthening the Reporting of OBservational studies in Epidemiology (STROBE) guidelines for an accurate ...
INTRODUCTION
Implant‐prosthetic rehabilitation is a clinical procedure used to solve cases of partial or total edentulism. A functioning implant may be subject to plaque‐associated biological complications, such as mucositis and peri‐implantitis.
Peri‐implant mucositis has been described as a reversible inflammatory lesion of the peri‐implant mucosa, whilst peri‐implantitis also desc...
