Temperature Measurement of Conventional and Vibrational Bone Drilling during Implantation Technique - An In-Vitro Study

Abstract

Bone drilling is the most common surgical technique in dentistry. The temperature will rise due to the forces and friction involved in drilling. As the temperature at the drilling site increases above the critical temperature, thermal necrosis occurs (47^oC). Thermal injuries, such as osteonecrosis, implant failure, and other complications, are linked to it, as is poor surgical treatment. In this proposed study to test these hypotheses, a thermocouple and a thermal camera will be used during the process of drilling (FLIR E5 XT Thermal Imaging Camera. Vibrational and conventional drilling tests were performed on a bone model, and the thermal changes of the bone and drilling bit were recorded. According to the findings of the statistical study, in conventional drilling study the temperature rise of the bone model and drill bit is directly related to the depth of drilling. As the rotational speed of the drill increases in relation to the depth of the hole, the drilling temperature rises. The experimental results with vibrational aid showed that the temperature was lower than the conventional method. Vibrational drilling is expected to reduce thermal necrosis and to contribute to postoperative recovery during dental surgery.
