Abstract
A method and apparatus for mounting a dental prosthesis to an upper or lower jaw of a patient. The apparatus includes a jig bushing and a base plate. The jig bushing has a plurality of apertures therethrough for guiding the travel of a drill bit for forming bores in the jaw of the patient. The base plate is immovably associated with the jig bushing and is formed to correspond to the shape of the jaw. A drill bit adaptor is provided for drilling bores in the ridge of the patient to an adjustable predetermined depth. The drill bit adaptor includes a plurality of annular recesses along a longitudinal length of the elongate body for receiving an E-ring. The body of the drill bit adaptor can be inserted into an aperture of the jig bushing until the E-ring presses against the jig bushing. Implants can be screwed into bores. Transmucosal adaptors having sloped ends can be added to each implant. Retaining screws can connect the implants with the transmucosal adaptors. The top plate can be seated on the sloped ends of the transmucosal adaptors.
