In Part I of this two-part study, the authors investigated heat production during osteotomy drilling at three different speeds, and determined that high-speed drilling produced the least heat when using 700 XL carbide burs. Part II of the study histologically examines the rate and quality of healing after drilling osteotomies at the three speeds in the mandible. Osteotomies were histologically examined 2, 4, and 6 weeks postoperatively. Histologic findings suggested that in the initial 6 weeks, the rate of healing and quality of new bone formation were higher after high-speed drilling than after low- or intermediate-speed drilling. These results, when considered with the results reported in Part I in which a 4.3 degrees C difference in heat production was observed between the speeds, seem to imply a relationship between heat production and healing for osteotomy drilling.
在这项分为两部分的研究的第一部分中，作者研究了在三种不同速度下进行截骨钻孔时的产热情况，并确定在使用700 XL硬质合金车针时，高速钻孔产生的热量最少。该研究的第二部分从组织学角度检查了在下颌骨以三种速度进行截骨钻孔后愈合的速度和质量。在术后2周、4周和6周对截骨部位进行组织学检查。组织学结果表明，在最初的6周内，高速钻孔后的愈合速度和新骨形成质量高于低速或中速钻孔。这些结果，再结合第一部分报告的结果（其中观察到不同速度下产热有4.3摄氏度的差异），似乎暗示了截骨钻孔的产热与愈合之间的关系。
