An Assessment of Cutting Force for Dental Implant Drilling

Abstract:

Bone drilling is widely used in orthopedics and dental surgery; it is a technically surgical procedure. Recent technological improvements in this area are focused on efforts to reduce forces in bone drilling. The aim of this study was to compare changes in cutting force during dental bone drilling at various drilling conditions and drill tool geometry. In the present in vitro study, dog jaw bone with uniform thickness of cortical bone was used. Cutting force changes were measured during drilling process. Drill jig was designed and manufactured to fix jaw workpiece and mounted on the tool dynamometer to measure cutting force in drilling process. The dental implant drilling tests were conducted at various cutting speeds and feed rates. In this study drilling thrust force was observed 1.5~3.6[N] for MS type implant drilling and 3.1~4.9[N] for conventional high speed steel drilling, respectively. This further research will provide a basic quantitative approach for the timely issue of wide application of implant drilling in dental and orthopedic surgery fields.
