Abstract
Abstract An intraosseous implant in which a rectangular anchor base is laterally inserted into a cavity cut into the mandible from one side. The cavity receives a portion of a drilling guide through which a drilling tool is directed to form a bore extending from the occlusal edge of the mandible through the cavity. A shank inserted through the bore is threadedly connected to the anchor base and to an anchor post for an artificial tooth in contact with the occlusal edge of the mandible.
