System for the manufacture of a dental prosthesis
A dental prosthesis is provided, manufactured from a monobloc or multibloc prosthesis blank (10), which is composed of a gum-colored material (14) and a tooth-colored material (12), which materials (12, 14) are bonded to each other by bonding, polymerization and/or one-piece manufacture. The boundary surface (16) between the materials is wave-shaped comprising alternating grooves (22) and ribs (24) in the course of the dental arch, and radial in an oral-vestibular direction in the region of the anterior teeth (33) to be created. The boundary surface (16), at least in the region of the molars (26)again as viewed in the oral vestibular directionhas parallel grooves (22) and ribs (24) forming troughs and crests of the waveform, or grooves (22) and ribs (24) such that they extend in deviation from parallel by at most 10 degrees, in particular at most 5 degrees, at least in the region of the molars (26).
Removable denture with metal denture tooth or teeth
The present invention provides a removable full or partial denture containing a linguoplate and metal occlusion of a restoring tooth or teeth with composite facing for restoring a tooth or teeth on the dental arch of a patient, wherein the denture utilizes a metal casting having the linguoplate, and at least one denture tooth on one side of the arch, and the at least one denture tooth is an extension of the linguoplate.
Method for Processing Prefabricated Prosthetic Teeth
The invention relates to a method for processing prosthetic teeth for the production of a full denture or at least a partial denture with at least two prosthetic teeth with the following steps: at least two prefabricated prosthetic teeth are inserted with their coronal sides into recesses an elastic mold, a clamping device is attached to the elastic mold, and after insertion of the prosthetic teeth into the elastic mold a mechanical pressure is applied to the elastic mold with the clamping device, wherein the pressure exerts a force onto the prosthetic teeth inserted into the elastic mold via the elastic mold and thus the prosthetic teeth are affixed in the elastic mold, the prosthetic teeth are positioned and aligned in the elastic mold in such a manner in relation to each other that at the latest following application of the clamping device on the elastic mold, the prosthetic teeth comprise the desired position and desired alignment in relation to each other, the elastic mold is affixed with the clamping device and prosthetic teeth in a defined position in a holder of a CAM device for removing material of the prosthetic teeth with a CAM method, and at least one of the prosthetic teeth affixed in the elastic mold is basally ablated with a CAM method.
The invention further relates to a device for holding prosthetic teeth for the implementation of such a method and a set for the implementation of such a method with such a device.
