Abstract A dental prosthesis with a metal body which has an internal cavity open at one end and which is provided with a facing of plastic, ceramic or the like is to be comparatively light and is to be of adequate strength, as well as being able to be used as posts for bridge constructions. For that purpose it is proposed that the metal body is formed as a carrier element (12) from a filigree grid or lattice having meshes, and is fixedly connected to the facing which surrounds same as a casing layer (10). In addition, two carrier elements (12) formed from the grid or lattice are to be connected by at least one bar (22) and supplemented by a grid or lattice portion (23) cast thereon, to form a bridge construction (21).

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
91 words
A lightweight dental prosthesis which comprisse an internal carrier element supporting an exterior casing, said carrier element defining a thimble-shaped metallic mesh or lattice bounded in part by an edge rib for increasing strength, said carrier element having been cast from a mold created by the lost wax process and said exterior casing defining a relatively thick layer of generally translucent material, said mesh defining a plurality of intersecting bars, portions of selected bars being bevelled or chamfered to create a locking connection between said carrier element and said casing layer.
