Abstract
It has been widely recognized that temperature and cutting time have significant effects on the performance of drilling for dental implantation. This study proposes a simplified drilling procedure which may reduce both the temperature changes and cutting time. Adopting a new design concept to reduce heat generation when drilling bone, a novel type of drills with a diameter of 3.0, 3.6, 4.1, and 4.6 mm are made. Performing a series of experiments with and without prior-drilling, the temperature changes and cutting time are measured in comparison to general drills. Artificial bones are used to minimize the effect of bone density on drilling. Analyzing experimental data, newly designed drills may reduce both the temperature changes and cutting time in comparison to general drill(P<0.001). The prior drilling procedure also have a significant effect on the temperature changes and cutting time(P<0.001). The results indicate that a simplified drilling procedure using newly designed drills are effective in reducing heat generation and cutting time when drilling bones.
