The results of the present case series study should be interpreted in a critical light because of the small study population.

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. The implant success rate was 77.9% for GCP...

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.

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. T...

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.

Background : Mucositis, peri-implantitis, and surv...

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...

Conclusion : A 1–7 year retrospective follow-up...

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 ...

Discussion : A 1–7 year retrospective follow-up...

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 ...

Discussion : A 1–7 year retrospective follow-up...

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...

Discussion : A 1–7 year retrospective follow-up...

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 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.

Background : A 1–7 year retrospective follow-up...

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...

Conclusion : A 1–7 year retrospective follow-up...

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 ...

Discussion : A 1–7 year retrospective follow-up...

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 ...

Discussion : A 1–7 year retrospective follow-up...

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...

Discussion : A 1–7 year retrospective follow-up...

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 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.

Background : A 1–7 year retrospective follow-up...

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 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...

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...

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...
