Taxa de sucesso a 5 anos de próteses fixas adesivas

: revisão sistemática com meta-análise

Abstract

Introduction: the aim of this investigation was to evaluate the success and/or survival rates of fixed adhesive prostheses reported in the published scientific literature with a minimum avereage observation time of five years and considering the location of the prosthesis, the number of pontics and retainers, the type of cement used, the design of the prosthesis, as well as the type of preparation on the abutment teeth. Methodology: systematic review with meta-analysis registered in PROSPERO (CRD42021236749), based on PRISMA standards with the research question PICOT: "In a partially edentulous population (P) do adhesive fixed partial dentures (I), compared to conventional fixed partial dentures (C), have superior clinical outcomes (O) at a minimum follow-up of 5 years (T)?" Search conducted in Pubmed®, Web of Science® and Cochrane® databases in free-text format and MESH terms, until May 2021. For the meta-analysis, the random effects model was used, for the estimated
survival rate, percentage per year of estimated failure and for existing complications. Study heterogeneity was assessed by the inconsistency test (I2) and study quality by the Downs & Black scale. Results: the defined search strategy included 11 articles, with a total of 687 participants and 783 adhesive fixed partial dentures, with a mean observation time of 8.2 years, with success rates mentioned in three articles and survival rates reported in nine articles. A total of 142 failures were reported for a total of 783 prostheses, the most frequent being debonding. The estimated failure rate (%/year) was estimated to
be between 0.535.10% per year. The studies were of sufficient quality. In the meta-analysis, the survival rates showed a significant result (p<0.001), with moderate heterogeneity (I2 = 58.76%). Conclusion: within the limitations of our study, mainly related to the heterogeneity of the studies and their quality, it seems possible to conclude that RBFPDs are a viable clinical option for the rehabilitation of patients with single edentation, particularly when using a single retainer and a zirconia-ceramic prosthesis.
