Introduction:
The purpose of this systematic review was to evaluate how prosthetic factors affect the incidence of peri-implantitis in patients treated with single implant restorations.
Methods:
Electronic and manual search of two indexed databases up to April 2023 were conducted, to identify clinical studies reporting on the effect of different prosthetic factors on the incidence of peri-implantitis around single implants and with at least 1 year follow-up. The risk of bias was assessed with the Joanna Briggs Institute critical appraisal checklist, the ROB2 and the ROBINS-I tools.
Results:
From the 521 screened articles, 11 studies (1 randomized controlled trial, 7 cross-sectional, 3 retrospective) met the inclusion criteria. Based on three studies, emergence angle⟩30°, convex emergence profile and external connection are associated with a higher incidence of peri-implantitis. Nine studies pertaining to the effect of retention type on the prevalence of peri-implantitis reported conflicting results. Six out of eleven included studies presented some risk of bias.
Conclusions:
There is insufficient evidence regarding the influence of prosthetic factors on the incidence of peri-implantitis around single implants. Further studies are needed to draw definitive conclusions on this issue.
