[Machining of bone with rotary cutting burrs].

The cutting of bone is widely used in medicine. Many different procedures are done with cutting burrs, reaching from orthopaedic surgery, traumatherapy up to oral surgery and dentistry. Accordingly are the variety of rotary cutting burrs. This paper describes the investigations of important cutting burrs such as rose-head burrs, diamond cutters and conventional bone cutters (Lindemann system). Main intent of this research is to study the thermal response, cutting quality and working accuracy of these instruments while boring and cutting cortical bone with regard to various cutting and using parameters. The results of this experiment are instructions for a highly improved handling of those instruments.
