Tooth implantation guiding handpiece more easily designing structures of a tooth mold fixing assembly required in the tooth implantation operation and a guiding plate

This invention provides a tooth implantation guiding handpiece which is used to drive a tool (drill bit). An outer circumferential surface of a bit presents a shape with a cylindrical arc-shaped surface. One side of the bit is connected to a handle. The bit is coaxially provided with a small-diameter portion at a bottom end thereof. The small-diameter portion is of a shape with a cylindrical arc-shaped surface and has a diameter smaller than that of the bit. The above outer circumferential surface and the small-diameter portion can be directly used together with a hole guiding means in a tooth implantation operation, such that structures of a tooth mold fixing assembly required in the tooth implantation operation and a guiding plate are more easily designed. Accordingly, effects of positioning and guiding the bit are better.
