Background:The aim of this study was to determine if a previous history of periodontitis according to the preset definitions of the 2017 World Workshop is correlated with increased implant failure, and occurrence and severity of periimplantitis (PI). Methods:A retrospective analysis of patients with a history of periodontitis who received nonsurgical and, if indicated, surgical corrective therapy prior to implant placement was performed. Periodontitis stage and grade were determined for each included patient based on data from the time of initiation of active periodontal therapy. Cox Proportional Hazard Frailty models were built to analyze the correlation between stage and grade of periodontitis at baseline with implant failure, as well as occurrence and severity of PI.Results: Ninety-nine patients with a history of periodontitis receiving 221 implants were followed for a mean duration of 10.6 ± 4.5 years after implant placement. Six implants (2.7%) failed and a higher rate of implant failure due to PI was found for Grade C patients (P < 0.05), whereas only an increased trend was seen for Stages III and IV compared with I and II. Grading significantly influenced the risk of marginal bone loss (MBL) >25% of the implant length (P = 0.022) in PI-affected implants. However, a direct correlation between higher-level stage and grade and PI prevalence was not recorded. Conclusion:No statistically significant association between periodontitis stage or grade and the prevalence of PI was found. However, when PI was diagnosed, there was a relationship between periodontitis grade and severity of PI or the occurrence of implant failure.

“…After removing duplicates and articles that did not fulfill the inclusion criteria, 46 potentially pertinent records remained (κ = 0.88). After the full texts were evaluated, 34 studies were further excluded, for the following reasons: Two 26,27 studies included implantsupported complete-arch prosthesis patients; 12 studies did not report implant length; 6,[28][29][30][31][32][33][34][35][36][37][38] 11 studies combined data for short and long implants, [39][40][41][42][43][44][45][46][47][48][49] and 9 studies did not involve short implants.

Purpose: To evaluate and compare the implant survival rates, marginal bone loss, and mechanical complications of prostheses supported by splinted and nonsplinted short implants (≤8.5 mm). Material and Methods: Electronic database (MEDLINE, CENTRAL, Web of Science, and EMBASE) and manual searches up to May 2021 were conducted to identify studies comparing splinted and nonsplinted short implants (≤8.5 mm). The primary outcome was implant survival rate. Secondary outcomes were marginal bone loss and mechanical complications. The quality of included studies and risk-of-bias were assessed according to the Newcastle-Ottawa Scale. A random-effects model was used to analyze the data. Results: Twelve studies fulfilled the inclusion criteria and featured 1506 short implants (596 nonsplinted and 910 splinted) with a follow-up time ranging from 1 to 16 years. Quantitative analysis found no statistically significant differences between splinted and nonsplinted short implants (≤8.5 mm) for survival rate (RR = 0.98; 95% CI 0.96, 1.01; p = 0.26)) and marginal bone loss (SMD = -0.08; 95% CI -0.23, 0.07; p = 0.28). Veneer chipping, abutment screw breakage, screw loosening, and loss of retention were reported in the selected studies as common complications. However, no statistically significant difference was found between splinted and nonsplinted short implants (RR = 0.56; 95% CI 0.20, 1.54; p = 0.26). Conclusions: Within the limitations of the present meta-analysis, it might be concluded that splinted short implants (≤8.5 mm) do not present superior performance in survival rate, marginal bone maintenance and prevention of mechanical complications compared with single-unit prostheses.Although the exact definition remains controversial, 1-3 short dental implants have been proven to be an acceptable solution for patients with limited alveolar bone height, which could substantially reduce treatment procedures, time, cost, and postoperative complications. 4,5 The survival rate of short implants is considered to be affected by a variety of factors. Implant factors include the lengths and surface treatments of implants and implant-abutment connection design. 6 Surgical and prosthetic factors include implant position (maxilla or mandible), surgical trauma, loading, etc. 6,7 Moreover, it is worth noting that selection of a suitable rehabilitation modality for short implants is also considered a crucial factor to maintain the long-term stability and success of short implants. 8

Purpose: The objectives were to characterize clinico-pathologically a large series of peri-implant peripheral giant cell granuloma (PGCG), and investigate the role of foreign material as a possible etiological factor. Material and methods:The study was retrospective, conducted on peri-implant specimens submitted for histology between 2005 and 2021.Results: Three hundred and thirty-five peri-implant biopsies were retrieved, of which 52 (15.5%) were PGCG. The study population included 28 females and 24 males, age 35-92 years, mean 61. 51.2% reported bone involvement. The lesion involved the margins of the specimen in 65.3%, recurrence was reported in 46.1%. In 58.8% the implant was removed at the same time the specimen was submitted for histopathological analysis.Small foci of black granular foreign material were observed in 53.8% of cases of which 67.8% were birefringent under polarized light. The foreign material granules were not ingested inside multinucleated giant cells, but were scattered in the stromal compartment.Conclusions: Peri-implant PGCG is locally aggressive, with frequent bone involvement and high recurrence rate, resulting in implant loss in the majority of cases. The high recurrence rate may be related to conservative or inadequate surgery. Foreign material although common does not seem to have a role in its development.dental implants, peri-implantitis, peripheral giant cell granuloma What is known• Peripheral giant cell granuloma have been reported to present around dental implants in single cases or small series, with undetermined prognosis • Fragments of metal have been suggested as a possible etiology What this study adds• The present study included 52 cases of peri-implant giant cell granuloma • These lesions comprise 15.5% of biopsied peri-implant lesions, and result in implant loss in 58.8% of cases • Small fragments of foreign material, probably titanium shreds are a frequent finding but are not ingested by the multinuclear giant cells and do not elicit a specific inflammatory response
