Abstract

Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, Ahead of Print.
Overheating of the bone during drilling may raise intraosseous temperature to more than 47°C, leading to osteonecrosis and compromising implant stability. Tool material, geometry and operating conditions play an important role in heat generation. ...
