Thermal Contact Simulation of Drill Bit and Bone during Drilling

In this study, a dynamic elastic-plastic finite element model is used to simulate the bone temperature rise during drilling process. Various rotating speeds and applied forces of the drill bit are investigated to explore the effects of these parameters on the temperature rise within the bone. The results indicate that a drill bit with a higher rotating speed or a higher applied force can have noticeable reductions on the bone temperature rise as well as the size of thermal effective zone.
