ABSTRACT
INTRODUCTION: The purpose of this systematic review is to determine if the zirconia implants present better clinical results when compared to titanium implants.
METHODS: Searches were conducted in 5 databases including, until March 2022, by 2 independent reviewers, according to the inclusion and exclusion criteria established in the study and according whit this question: Do zirconia dental implants present better clinical results than titanium dental implants?
RESULTS: 3235 studies were initially found in the researched databases. 03 randomized clinical trials were included in this systematic review and meta-analysis. A total of 71 patients with 192 implants (87 titanium and 105 zirconia) were evaluated, showing an effectiveness of 87,4% and 78,1% respectively and there was no statistically significant difference in terms of survival rate in the meta-analysis (P = 0.70; I2 = 0%). Still in the meta-analysis, there was no statistically significant difference between titanium and zirconia implants in relation to the pink esthetich score or bleeding on probing, however, a favorable difference was observed for titanium in relation to marginal bone loss (P = 0.001; I2 = 0%). None of the studies evaluated had a low risk of bias.
CONCLUSION: Oral rehabilitation with zirconia implants showed no advantages over titanium in this systematic review. However, the small number of studies included and the uncertain risk of bias may raise doubts in this interpretation and the results should be analyzed with caution. New studies with greater methodological rigor, follow-up time and number of interventions should be performed in order to safely determine the indication for the use of zirconia implants.
