A Study In High Speed Cutting With Dental Burrs

The work presented details the development of an experimental proced-ure enabling investigations into dental cutting mechanics to be carried out. Use has been made of high speed cinemacrography with framing speeds up to 22,000pps being recorded. This provided a clear view of the action of modern high speed rotary dental instruments and allowed analysis of chip trajectory dynamics and cutting efficiency at different cutting parameters.© (1979) COPYRIGHT SPIE--The International Society for Optical Engineering.
