“…As can be seen in the data presented in Table , a clear trend was the evaluation of implant survival solely, rather than overall success, when defining the success criteria. Thus, 12 studies cited implant survival as their main outcome, while five studies stated that they intended to use some predefined criteria for success assessment (eg, Albrektsson et al, Buser et al), although this goal was not necessarily achieved. Of those studies reporting a success rate, one study reported a survival rate and patients' subjective sensation, one study reported a survival rate, clinical parameters and patients' subjective sensation, and one study reported a survival rate and clinical parameters .…”

“…Only two studies reported the full extent (ie, on the additional three parameters in the success criteria by Albrektsson and colleagues) of the aspects . Four studies reported solely on survival without reporting any of the additional parameters for success . The three remaining aspects, which should be assessed along with survival according to Albrektsson et al, were reported in a broad palette of combinations by the included studies.…”

“…Panoramic radiographs were included in six studies: in two of them, the images were taken annually, in 2, at 5 and 10 years' follow‐up, in one study, images were acquired annually until 5 years and then every 2 years, and finally in one study, radiographs were acquired only at 5 years' follow‐up . In three studies, the type of radiographs and the time of acquisition were not specified . Although 14 studies included some sort of radiographic evaluation of the implants, only 10 of these included MBL assessment as part of their methodology.…”

“…Four studies with a follow‐up of 10 years reported on survival rates of 90%‐95%. Two studies reached longer follow‐up periods (11.4 and 15 years) and reported survival rates of 93.4% and 88.7%. With regard to overall success, three studies presented data from 5 years' follow‐up, with success rates ranging from 86.8% to 100%, one study presented data on 5.5 years with a success rate of 86.9% while one study presented a longer follow‐up period (12 years), presenting a success rate of 90.2% …”

Background An enduring clinical question concerns the outcome (ie, success) of implants placed in areas grafted with block‐grafts. Objective To undertake a systematic review of the literature on the long term results (≥5 years) of implants placed in maxillofacial areas grafted with any type of osseous block‐grafts in two‐stage surgeries. Further, the review addresses how available success criteria were used within the studies. Materials and Methods The MEDLINE (PubMed) and EMBASE bibliographic databases were searched up to March 2017 for studies evaluating the long term results of implants placed in grafted areas. The search strategy was restricted to English language publications using combined terms which referred to the treatment method (implants placed in areas grafted with bone blocks), and follow‐up characteristics (≥5 years and assessment of at least one parameter related to implant success criteria). To qualify for inclusion, studies should present outcome measurements indicating the success (or at least the survival) of the implants. Results The search strategy yielded 17 studies, which were included in this systematic review. These studies presented survival rates ranging from 88.7% (after 15 years follow‐up) to 98.7% (after 5 years follow‐up). Five studies presented data based on predefined success criteria with success rates ranging from 86.8% to 100%. In these studies, the term “success” was often not properly defined. Conclusion The long term survival (≥5 years) of implants placed into block‐grafted areas in two‐stage surgeries was not lower than 75%, while success rates ranged from 86.8% to 100%. Although it was possible to identify published success criteria for implant follow‐up, there is no broad consensus on how to report implant success in a consistent manner.

Purpose To prospectively assess long‐term (20 year) clinical, radiographic, and patient‐reported outcomes of an elderly population provided with mandibular implant‐supported overdentures. Materials and Methods A total of 53 elderly (aged ≥60 years at the time of treatment) were provided with two endosseous implants supporting a mandibular overdenture and a conventional maxillary denture. Outcome parameters—including implant loss, plaque index, gingival index, bleeding index, presence of calculus, probing depth, and satisfaction with implant‐supported overdenture—were scored 1, 5, 10, and 20 years after prosthetic treatment. Radiographic analysis was performed to assess peri‐implant bone changes. At the 20‐year evaluation, frailty (Groningen Frailty Index) and quality of life (EuroQol 5D) were additionally assessed. Results A total of 15 patients completed the 20‐year follow‐up. The 20‐year implant survival rate was 92.5%. Plaque index, bleeding index, and probing depth increased slightly over time, while gingival index and presence of calculus remained unchanged. Radiographic analysis revealed minor marginal bone loss during the first 10 years and no further loss thereafter. Participants were very satisfied with their prosthesis and reported a good quality of life. At the 20‐year evaluation, 64.3% of the patients were classified as frail. Conclusions The long‐term survival of implants supporting a mandibular overdenture is high. Although most elderly in the study became frail over time, peri‐implant health and marginal bone level remained at a satisfactory level.

BackgroundGuided bone regeneration (GBR) is the most widely used technique for overcoming the deficiency of alveolar bone. However, the progression of peri‐implantitis in regenerative and pristine bone sites has not been fully investigated. The aim of this study is to compare experimental peri‐implantitis around implants placed in pristine bone and GBR sites.MethodsBilateral mandibular first molars were extracted from six beagle dogs, and standardized horizontal ridge defect was simultaneously created at predetermined site in unilateral mandible. After 8 weeks, guided bone regeneration procedure was conducted at the defect site. After 16 weeks, implants (ϕ 3.6×8.0 mm) were placed at both extracted sites. This study included 3 months of active breakdown and another 3 months of spontaneous progression period. Radiographs were taken at each phase and specimens were obtained for histological, immunohistochemical, and polarized light microscopic analysis.ResultsMarginal bone loss around implant did not show the significant differences between pristine bone and GBR sites during spontaneous progression period. In immunohistochemical analysis, inflammatory and immune‐related cells were predominantly detected in peri‐implantitis‒affected area rather than unaffected area. In the polarized light microscopic analysis, substantial reductions in the amount and thickness of collagen fibers were observed in peri‐implantitis‒affected area compared with unaffected tissues. However, there were no significant differences in histological, immunohistochemical, polarized light microscopic outcomes between pristine bone and GBR sites.ConclusionPrevious hard tissue grafting at the implant sites did not affect experimental peri‐implantitis and exhibited similar radiographic, histological, immunohistochemical, and polarized light microscopic outcomes compared with those of pristine bone sites.
