摘要： A maxillofacial anchoring and distraction system having an internally threaded anchoring or distraction fixture (12) and a selected length jack screw (14) for placement in an osteotomy. To minimize required bone height, a cut-away bone screw (16) or a solid mesh tip (17) is provided for insertion in bone in a direction generally perpendicular to the longitudinal axes of the anchoring and jack screws. A flat surface portion (16c, 17a) serves as a reaction surface for the distal end of the jack screw. In a second embodiment a sealing screw (24) is used with distraction fixture (20) modified to include a sealing surface. After completion of distraction the sealing screw is used to seal off the distraction fixture for conversion into an implant suitable for receiving conventional prosthetic components.

摘要： A self-drilling and tapping multi-drive bone screw (10) for rigid fixation of craniomaxillofacial tissue grafts and bone plates has a tip (12a) which incorporates a defined twist drill shaft with a sharp cutting point tip (12b) to easily pierce and drill a pilot hole and prepare for the insertion of self-tapping screw threads (12c). A cylindrical dome shaped head (14) for rigid fixation of craniomaxillofacial tissue grafts and geometrically sized bone plates is formed on the screw distal to the drilling and tapping features. A spline feature (14e) is incorporated into the cylindrically dome shaped head for easy pickup, assembly and insertion of the bone screw with a corresponding spline driver tool (20). The spline driver feature also allows the bone screw (10) to be driven with either a standard square or cross blade driver tool.

摘要： A dental torque ratchet head and driver handle (8) is formed with a chamber (12a) between first (30) and second (32) pivotably mounted handle members which receives a plastic insert (14) formed in a configuration selected so that the insert fractures at a selected torque to thereby ensure the application of a precalibrated level or torque to an abutment or prosthetic screw of an implant. A solid metal insert (14') can be used to convert the tool to a straight ratchet tool.

摘要： An endosseous dental implant system includes a dental implant having a multi-sided projection at its top end and an internally threaded or unthreaded passage extending into the body of the implant through an opening in the projection at the top of the implant, and an abutment having an internal passage for receiving a fastener that passes through the internal passage of the abutment, and threads into the internal passage inside the implant. The abutment has a multi-sided internal cavity at its bottom end with each of the cavity sides perpendicular to the longitudinal axis of the abutment so that the cavity, when seated over the projection at the top of the implant, forms an anti-rotational, interlocking junction with the implant.
