目的：评价不锈钢、类金刚石(DLC)涂层和氧化锆钻在多次截骨后的变形、粗糙度和质量损失。材料和方法：分别使用不锈钢(G1)、类金刚石涂层(G2)和氧化锆钻(G3)进行钻削。实验分为1、2、3、4、5组，分别对应钻头使用0、10、20、30、40次。结果：各组间质量和粗糙度差异均无统计学意义。在扫描电子显微镜图像中，所有组都显示出磨损迹象，而G2组则检测到涂层剥离。结论：氧化锆钻头表面规则，而不锈钢钻头磨损严重。必须进行进一步的研究，以评估这些发现对热量产生的推定影响。
Purpose:The aim of this study was to evaluate deformation, roughness, and mass loss of stainless steel, diamond-like carbon (DLC)-coated and zirconia drills after multiple osteotomies with sterilization procedures.Materials and Methods:Drilling procedures were performed using stainless steel (G1), DLC-coated (G2), and zirconia (G3) drills. All groups were divided in subgroups 1, 2, 3, 4, and 5, corresponded to drills used 0, 10, 20, 30, and 40 times, respectively.Results:No significant differences in mass and roughness were detected among all groups and subgroups. In SEM images, all groups revealed signs of wear while coating delamination was detected in G2. Drills from G1 displayed more irregular surface, whereas cutting edges were more regular in G3.Conclusion:Zirconia drills presented more regular surfaces whereas stainless steel drills revealed more severe signs of wear. Further studies must be performed to evaluate the putative influence of these findings in heat generation.
