Estudo comparativo das taxas de sucesso de implantes instalados por cirurgia guiada e cirurgia convencional: revisão de literatura

Abstract

The last few decades have brought many changes to the daily clinical practice in Dentistry and technology has been increasingly applicable and accessible. The emergence of computed tomography made it possible to plan virtual surgeries for the installation of implants and to make high-precision prototyped surgical guides. As a consequence of this evolution, guided surgery emerged with indication for the most variable types of rehabilitation with implants, including patients with total or partial edentulism. The aim of this study was to evaluate, through an integrative literature review, the success rates of implants installed using the guided surgery technique compared to the results of conventional surgery. The electronic search was performed using different combinations with the following descriptors: dental implant, survival rate, and guided surgery. After selecting the articles, information was extracted regarding the type of study, surgical technique used, type of prosthetic loading, type of prosthesis, number of patients and implants evaluated, follow-up time and implant survival rate. Percentage data on survival rates were tabulated and submitted to descriptive analysis of mean and standard deviation. Survival rates reported for conventional surgery ranged from 92.6 to 100% (mean 96.41 ± 1.92%), while for guided surgery they ranged from 90 to 100% (mean 97.70 ± 2.35 %). From the methodology used and considering the limitations of this study, it is concluded that the technique of implant installation through guided surgery and planned by computer constitutes a safe, viable and predictable procedure, presenting survival rates comparable to those achieved by the technique of conventional implant installation. Further studies are needed to confirm the results found.
