On the basis of this study, the following conclusions can be made:--Although the primary cause of the diminution of cutting efficiency when composite restorations are cut is due to abrasion, a secondary cause is the adhesion of the melted resin to the flutes.--Amalgams and tooth structures cause significantly less wear to burs than composite restorations.--The design of burs currently used is probably a poor choice to remove composite restorations.
基于本研究，可得出以下结论：——虽然复合树脂修复体切割时切割效率降低的主要原因是磨损，但次要原因是熔化的树脂粘附在排屑槽上。——银汞合金和牙齿结构对车针造成的磨损明显小于复合树脂修复体。——目前使用的车针设计对于去除复合树脂修复体而言可能不是一个好的选择。
