METHOD AND APPARATUS FOR DETERMINING A BRIDGE FOR ANCHORING ELEMENTS IN THE DENTAL

Abstract

Abstract PCT No. PCT/SE87/00574 Sec. 371 Date May 16, 1989 Sec. 102(e) Date May 16, 1989 PCT Filed Dec. 2, 1987 PCT Pub. No. WO88/04158 PCT Pub. Date Jun. 16, 1988.A bridge for an artificial dental structure is made of titanium. The bridge is constructed from modular elements which are adapted one to the other and are treated for joining together, for example by means of laser welding. In a first treatment unit one or more first treatment stages are performed for the construction of the bridge. Identification data introduced or utilized in this or these stages relating to the individual different heights of the anchorage elements above the dentine and their different relative inclinations, and the positions and directions of the modular elements in relation to one another and to the anchorage elements are obtained and stored. In a subsequent processing stage which is executed by a processing unit the latter is controlled depending on the extracted and stored information, so that any bridge elements present in the bridge between the attachment components of the bridge in the anchorage elements are assured a connection via the contact surfaces and directions and dimensions between the attachment components such that the bridge elements are essentially in line with the direction of the dentine in the sense of its height and width, at the same time with the necessary strength and location within the dental structure.
