How To Determine The Cutting Performance (end Cutting, Side Cutting) Of Dental Drill For Implant?

The cutting performance of the dental drill for implant can be divided into end cutting and side cutting. The administrative counterpart may select the applicable cutting performance test according to the functional characteristics of the dental drill. Except for the disposable sterile dental drill, the cutting test should be conducted after high temperature and high pressure steam sterilization, and consider the thermal effect of sterilization. The cutting test can be conducted with reference to the method specified in the annex of “Guidelines for Technical Review of the Registration of Drill for Dental Implantation Surgery”. The average time for the dental drill to cut five holes in the end cutting test as well as the time for the dental drill to cut a distance five times of head diameter in the side cutting test may be independently specified by the administrative counterpart, but it is necessary to demonstrate that it can meet the needs for clinical use.
