Abstract
A self-tapping screw-shaped dental implant for implantation in bone tissue is disclosed. The implant serves as an anchor for artificial teeth, tooth bridges or other dental prostheses and comprises a screw body with an external thread. The implant is characterized by one or more cavities in the screw body. The cavities include a cutting edge with cutting teeth. At least one of the cutting teeth is provided with a beveled relief surface defined on the outer surface of the implant behind the cutting tooth and at least one of the cutting teeth is provided with a full threaded outer surface on the implant behind the cutting tooth. In the case of multiple cavities, the cavities may extend to different heights along the screw body. The implant is also characterized in that the upper surface of the each of the cavities is parallel to the thread.
