Abstract

Abstract: Aim: To investigate fully edentulous patients rehabilitated with cantilever‐fixed implant‐supported restorations and to analyse which complications are reported for this type of treatment. Materials and Methods: Two operators screened the literature (MEDLINE, EMBASE) and performed a hand search on the main journals dealing with implantology and prosthetics until 31 December 2017. Only articles that considered cantilever implant‐fixed restorations with at least 10 patients and with a mean follow‐up of at least 5 years were selected. The outcome variables were survival of implants and prosthesis, mechanical, technical and biological complications, marginal bone loss. The review was performed according to the PRISMA statements. The risk of bias was evaluated for each article. Failure and complication rates were analysed using random effect Poisson regression models to obtain summary estimate of 5‐ and 10‐year survival and complication rates. Results: Fourteen papers for fully edentulous patients were selected. The estimated 5 to 10 years survival rate was calculated to be 99.00% and 96.7% for the implants and the prosthesis, respectively. A total of 299 complications (technical and biological) were reported with a cumulative 5–10 years complication rate of 44.41% and 39.46% for the patients and for the prosthesis, respectively. Conclusions: There is evidence that cantilever can be successful treatment in fully edentulous patients.
