BackgroundOverload from bruxism may affect survival of dental implants.ObjectivesTo evaluate implant failure and marginal bone loss (MBL) in patients presenting with probable bruxism compared to non‐bruxers. The study was registered in PROSPERO (CRD42021238397).MethodsAn electronic search September 2022 in PubMed/Medline, Web of Science and Science Direct was combined with a hand search. Two independent reviewers carried out abstract screening, full‐text assessment, quality assessment (National Institutes of Health tool) and data extraction. Only studies that provided information on self‐report and clinical examination needed for the diagnosis of at least ‘probable’ bruxism were included. A pairwise random‐effect meta‐analysis was carried out.ResultsIn total 1338 studies were identified, and after screening and full‐text assessment 27 studies that presented data on 2105 implants in probable bruxers and 10 264 implants in non‐bruxers were included, with 138 and 352 implant failures in respective groups. the meta‐analysis showed that implants placed in probable bruxers had a higher risk of failure than in non‐bruxers (OR 2.189; 95% CI 1.337, 3.583, p = .002). A meta‐regression showed that follow‐up time did not affect this OR. Eighteen studies provided general data on MBL but did not report results separated between bruxers and non‐bruxers. Therefore, an analysis of MBL was not possible.ConclusionThe results of the present systematic review show that implants placed in probable bruxers present a significantly higher risk of failure than implants placed in non‐bruxers. This should be considered in treatment planning and management of implant patients.

“…The topic under study is of great relevance because some of the most common complications in implant prosthodontics have been mechanical complications. Abutment screw loosening has been reported as the most common prosthetic complication, which has been associated with preceding the more challenging abutment screw or even implant fracture [7,8] The incidence of abutment screw fracture has been examined by certain authors, such as Katsavochristou and Koumoulis. These authors concluded that the incidence of screw loosening falls within the range of 7% to 11%.…”

Implant-supported-screw-retained prostheses are really popular. Some of the most frequent complications have been mechanical complications. These include abutment screw loosening or even screw fracture. Using an intermediate abutment can offer several advantages. However, little literature has been found regarding how this affects the mechanical behavior of dental restorations. This study focuses on understanding the mechanical behavior of implant-supported restorations with a transepithelial component compared to those with a direct implant-supported restoration. It was carried out by using the Finite Element Method (FEM) and was experi-mentally validated. The results showed that in the case of transepithelial-supported restoration, the prosthetic screw mounted over the transepithelial component suffers higher stress than the one screwed directly to the implant. After applying a cyclic fatigue load, it is experimentally proven that, in the transepithelial-supported restorations, the fuse changes from being the screw that goes to the implant, to being the upper one. As a conclusion we can say that the use of an intermediate abutment in dental restoration not only provides better protection to the rest of the dental restoration but also allows easier repair in the event of a fracture. This can potentially lead to more efficient procedures and improved patient outcomes.
