dc.description.abstractBackgroundThe purpose of this in vitro study is to compare the removal torque values of abutment screws anodized with different voltage values.MethodsThe abutment screws were divided into 6 groups according to their surface treatment: non-treated (C) Control group (n = 24), acid etched only (A) Acidic uncolored (n = 24), anodized with 27 V and painted blue (B) Blue (n = 24), after acid etching anodized with 27 V and painted blue (AB) Acidic Blue (n = 24), anodized with 55 V and painted yellow (Y) Yellow (n = 24) and after acid etching anodized with 55 V and painted yellow (AY) Acidic Yellow (n = 24). 144 bone-level implants to which the abutments will be attached are embedded in auto polymerized acrylic resin. All abutment screws were tightened to 30 Ncm on the digital torque meter. The removal torque values of abutment screws were obtained, and A three-way ANOVA was performed for statistical analysis, and Tukey's test was used for multiple comparisons.ResultsDecreased removal torque values were observed in all groups after thermomechanical cycling. Only application anodization process to abutment screws reduces removal torques of the screws. In case of acid etching before anodization, it was observed that removal torques increased. Applying only acid etching process to abutment screws reduces removal torques of the screws. However, when the screws are anodized after acid etching, it has been observed that removal torques increase.ConclusionIt was observed that anodizing the abutment screws with different voltages did not make a significant change in the removal torques.
