Abstract

The thread of dental implants screw has to meet special requirements and it has specific axial profiles. The constructive shapes of dental implants screw are diverse but still they have some common features: thread (cylindrical or conical), entering cone, self-threading flutes. The thread is usually machined by turning with profiled cutters, on NC machine tools. In this paper, a method to profile the screw-die tools, used to generate by rolling the thread for a dental implant type of screw is presented. The profiling problem was solved by two methods: an analytical method, based on the fundamental theorem concerning the enwrapped surfaces, and a graphical method, based on a CAD environment for graphical design. The paper includes comparative numerical examples, obtained by running the two methods in the case of the same thread profile.
