10个尸检颌骨标本（6个下颌骨，4个上颌骨）用于低速螺纹过程中的切割阻力测量。总体而言，分析了31个将种植体插入螺纹管的部位。如前所述，在种植体周围进行骨面积测量。切割阻力值与总骨面积值一起被发现是在下颌骨比在上颌骨更高，并朝着更高的价值观的趋势被认为是在切牙区相比，前磨牙区。此外，真实切割阻力和准备部位骨密度值之间的个体内比较显示出统计学显著相关性。因此，至少在人类尸检颌骨标本中使用时，用于评价骨质量的切割阻力测量方法似乎是可靠的。
Ten autopsy jaw specimens (6 mandibles, 4 maxillae) were used for cutting resistance measurements during low-speed threading. Overall, 31 sites were analyzed where implants were inserted into threaded canals. Bone area measurements were performed around the implants as described previously. The cutting resistance values together with the total bone area values were found to be higher in mandibles than in maxillae, and a tendency towards higher values was seen in incisor regions compared with premolar regions. Furthermore, an intraindividual comparison between the true cutting resistance and the bone density values of prepared sites showed a statistically significant correlation. The method with cutting resistance measurements for evaluation of bone quality seems therefore to be reliable, at least when used in human autopsy jaw bone specimens.
