A socket for use in preparing a dental prosthesis and in attaching the prosthesis to pillars attached to the patient's jawbone has a thin-walled tubular extension portion that is long enough to extend entirely through an impression material for the first mold used in preparing the prosthesis and/or through the bridge element of the prosthesis. One or more grooves on the socket enhance retention of the first mold and the bridge element.

Method for affixing a dental prosthesis

Implant for attachment of dental prosthesis to the jawbone

A device for fixing a dental prosthesis is described, which device as parts thereof comprises a spacing element (1) for anchoring into the jaw-bone of a patient and a socket (7) for fixing into a prosthetic part, whereby the socket will rest on the spacing element via an outer conical supporting surface (5) provided on one of said parts, which supporting surface will bear against an inner conical supporting surface (6) provided in the other of said parts. The device is characterized in that a shoulder or flange is provided on the part having the outer conical supporting surface, which shoulder or flange has a planar surface (8) oriented radially around the periphery of the supporting surface, and that an end surface (9) is provided on the part having the inner conical supporting surface oriented radially around the periphery of said supporting surface, whereby the planar surface (8) and the end surface (9) has such an axial position on the respective part that a fine parallel gap is formed between them on bearing of the supporting surfaces against each other. The gap enables checking of the correct bearing of the conical surfaces against each other.

Device for fixing a dental prothesis

A dental bridge assembly comprises a bridge component cast from a gold alloy having a melting point not greater than 1050.degree. C. and a plurality of sockets of titanium or a titanium alloy cast in place in the bridge component, secured mechanically to the bridge component and adapted to be fastened to anchor elements attached to the jawbone of a patient.

Dental bridge and manner for preparation

Tool for a prosthetic part

Drill-mountable tool for the installation and removal of threaded dental

The invention relates to a method and a means for preparation of a dental bridge for a dental prosthesis. The dental bridge is modelled by casting in a mould prepared from a casting model. The casting model is built up in the mouth of the patient by modules (3,6) which are joined together into a unit. A module consists of a metal socket (3) on which a cap (6) with a through hole is mounted. The modules are connected to each other preferably by gluing.
