Production of a dental prosthesis by printing prosthetic base onto prosthetic teeth
The invention relates to a method for producing a dental prosthesis, wherein the dental prosthesis comprises a prosthetic base and a plurality of prosthetic teeth, wherein the method is carried out with the use of a virtual three-dimensional dental prosthesis model of the dental prosthesis which is to be produced, and wherein the virtual three-dimensional dental prosthesis model comprises virtual prosthetic teeth and a virtual prosthetic base, including the following chronological steps: A) producing a physical occlusion plate, wherein a region of the surface of the occlusion plate is formed by a negative of the coronal sides of the virtual prosthetic teeth of the virtual dental prosthesis model, wherein the location and orientation of the virtual prosthetic teeth relative to one another corresponding to the virtual dental prosthesis model remain retained in the shape of the surface of the occlusion plate; B) placing and securing preassembled prosthetic teeth on the occlusion plate, wherein the coronal sides of the pre-assembled prosthetic teeth are placed on the surface of the occlusion plate formed by the negative; C) securing the occlusion plate, with the prosthetic teeth secured therein, in a device for the layered forming of three-dimensional plastic structures; and D) printing the prosthetic base onto the basal ends of the prosthetic teeth with the device for the layered forming of three-dimensional plastic structures on the basis of the shape of the virtual prosthetic base. The invention also relates to a dental prosthesis produced with such a method and a device for carrying out such a method.
Method for processing prefabricated prosthetic teeth
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, a device for holding prosthetic teeth for the implementation of the method, and a set for the implementation of the method with the device. The method includes the following steps: inserting at least two prefabricated prosthetic teeth with their coronal sides into recesses of an elastic mold, attaching a clamping device to the elastic mold, and applying mechanical pressure to exert force to affix the prosthetic teeth in the elastic mold, positioning and aligning the prosthetic teeth in a desired position and a desired alignment in relation to each other in the elastic mold, affixing the elastic mold 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 basally ablating at least one of the prosthetic teeth affixed in the elastic mold with the CAM method.
DENTAL MATERIAL FOR THE PREPARATION OF FULL OR PARTIAL DENTAL PROSTHESES
A radically polymerizable material for the preparation of dental prostheses, containing (a) at least one monofunctional radically polymerizable (meth)acrylate, (b) at least one polyfunctional radically polymerizable (meth)acrylate, (c) at least one ABA triblock copolymer, (d) at least one nanoparticulate or microfine filler having an average primary particle size of from 10 nm to 350 nm, and (e) at least one photoinitiator. The A block of the ABA triblock copolymer is an oligomeric polyester and the B block is an oligomeric polysiloxane.
Digital correction factors and mounting with digital correction factors of real prefabricated prosthetic teeth
The invention relates to correction factors, in particular digital correction factors or printed correction factors, as translation (x,y,z) data and/or as data of the rotation of at least one real prefabricated prosthetic tooth up to a plurality of real prefabricated prosthetic teeth in a mounting for material-ablating processing of the prosthetic teeth, the correction factors preferably being assigned to the mounting as bar code or as quick-response code for use in a digitally controlled material-ablating process, the mounting having at least one fixed real prefabricated tooth. The invention also relates to the mounting with assigned digital correction factors as well as to a method for determining the digital correction factors of the at least one real prefabricated prosthetic tooth.
Method for producing a dental prosthesis, blank and dental prosthesis
A method is provided for producing a dental prosthesis from a blank using a CAD/CAM device, wherein the blank consists partially of base material and partially of tooth material, and a boundary surface between these materials is formed as a wave, the wave crests and wave valleys of which alternate with each other along the outer periphery of the blank. The apex of each wave crest extends substantially radially with respect to the blank. The CAD/CAM device fixes the position of a retention part, which serves to fasten the prosthesis to the alveolar crest of a patient, in particular of an external telescope, of a cover of a bar, or of an abutment in the prosthesis in such a way that it passes through the boundary surface. The retention part is fastened by means of gluing or incorporation by polymerisation.
