Particularities of the implant-supported prosthesis in patients with bruxism: systematic review of the literature.

Bruxism concerns diurnal and nocturnal parafunctional activities, including grinding, rubbing, tapping, and clenching of the teeth. This study aims to assess the longevity and reliability of implant-supported prostheses made for patients with bruxism and establish the criteria for success and failure for these prostheses. A search in the Medline-PubMed, Web of Science, Scopus, and Google Scholar databases was conducted; the last computer search was on 20th October 2025, with no period filter. Studies published in English with a follow-up period of at least 6 months were considered. The writing of this literature review followed the guidelines of the PRISMA Statement (Preferred Reporting Items for Systematic Reviews and Meta-Analysis). Implant survival rates among bruxers ranged from 57.5% to 100% over an average time period of 12 to 291 months, remaining lower than those noted in non-bruxers. Rates of mechanical complications reach up to 60%, and prosthetic failure rates up to 29.3% in patients with bruxism. However, wearing a protective splint was associated with a 1.8-fold reduction in wear of prosthetic materials. The particularities found in patients with bruxism require the practitioner to take certain precautions during the rehabilitation with implant supported prosthesis to be able to make up for its vulnerability and ensure its sustainability.
