Reabilitação de arcadas completas com prótese fixa implanto-suportada em zircónia monolítica

: uma revisão sistemática com meta-análise

Abstract

INTRODUCTION: In full-arch rehabilitation with fixed implant-supported prosthetics, the use of monolithic zirconia seems to have several advantages related to function and esthetics. However, the published scientific evidence is still limited. The aim of this investigation was to review the published scientific evidence on monolithic zirconia restorations, particularly on success/survival rates and mechanical and biological complications. MATERIALS AND METHODS: A systematic review was carried out, with a protocol registered in PROSPERO. The primary literature search was done in PubMed® and Web of Science® and complemented with the bibliography of the searched articles. Inclusion and exclusion criteria were defined. The PRISMA flowchart was followed for article selection. To evaluate the quality of the studies we used the tools provided by Joana Briggs Institute. A meta-analysis was performed for the variable survival rate (%), applying the specific continuous moderator, patients' follow-up period. Data heterogeneity (I2) was assessed with Forest Plot and Funnel plot. RESULTS: From the initial search, 327 references were obtained. After eliminating duplicates and applying the inclusion/exclusion criteria by reading the titles, abstracts, and full text, 7 articles were included for analysis. All included articles were observational longitudinal retrospective, with a number of prostheses between 7 and 2039. The mean age of the rehabilitated patients was 60 years. The position of the prosthesis varied between mandibular, maxillary or bimaxillary, always with screw-retained retention, with a number of implants ranged from 4 to 8. Mean follow-up time: 49.7 months. The percentage of article quality was over 70% and heterogeneity was low (I2=28.64%). The average survival rate was 97.23%. CONCLUSION: In a mean follow-up time of approximately 4 years, monolithic zirconia implant-supported full-arch rehabilitations have a high survival rate and minimal complications.
