Resumo

Some research suggest that the good condition of the drills used in osteotomies for dental implants is fundamental to a minimally invasive surgical technique, decreasing the temperature when preparing the surgical area. Objective: Analyze the wear of the drills used in osteotomies for dental implants, comparing the physical changes of the groups and types of coatings after their use, as well as evaluating the difference in these changes with and without sterilization. Ninety-six drills were used, 48 of which were spear-type (24 steel and 24 Diamond like carbon (DLC)) and 48 helical-type (24 steel and 24 DLC), divided into four groups: (G0), (G1), (G2) and (G3), with 0, 45, 90 and 135 osteotomies, with and without sterilization, evaluated by scanning electron microscopy (SEM). In this study, were used bovines ribs, with dimensions of 20cm in length, for osteotomies. Results: Wear of the drills after 90 osteotomies, p-value < 0.001; no evidence was found about the wear related to the sterilization process; and better performance of the steel twist drills in group G2 compared to the DLC twist drills in the same group, analyzed using the Mann-Whitney and Friedman statistical tests, as well as Dunn's post hoc test. Conclusion: Considering the wear and tear on the drills, their reuse is safe for up to 90 osteotomies.
