[0004] During the process of screwing the implant into the external mounting hole, when the implant is inserted into the external mounting hole, the implant can gradually enter different depth positions in the external mounting hole. Different positions on the implant can be at different depths in the external mounting hole, and the resistance encountered by the implant at different depths and the required self-tapping ability are different. Implants of different lengths encounter different resistances and require different self-tapping abilities. The existing cutting grooves of implants are opened very randomly, and the existing cutting grooves cannot meet the variable self-tapping ability required by the implant.
