Abstract

Nowadays, Implantation is one of the inevitable methods of internal fixation in orthopedic surgery and dentistry. In many cases, bone drilling causes an increase in bone temperature (more than 47 ℃) and this phenomenon leads to thermal osteonecrosis. In addition, excessive thrust force during drilling process increases probability of drill bit fracture. In this study, it has been shown that high-speed bone drilling is an appropriate method for descending process temperature and force simultaneously. Also, rotational speed, feed rate and tool diameter are the most important factors of the process. In high-speed bone drilling, contrary to conventional drilling process, high rotational speed results in a decrease in process temperature and force. Therefore, in robotic surgery high-speed bone drilling is considerably suitable method for implantation
