Abstract

This invention relates to a method for producing dental prostheses, having the steps of: A) producing a prosthetic base with at least one receptacle and one protruding pin or providing such a prosthetic base; B) producing or basally machining at least one dental molding with a basal cavity for receiving the pin and a lateral opening in the circumferential surface, such that the basal cavity is accessible via the lateral opening; C) subsequently applying an adhesive into the basal cavity and/or into the at least one receptacle; D) subsequently inserting the at least one dental molding into the at least one receptacle of the prosthetic base, such that the protruding pin is arranged inside the basal cavity; E) subsequently pushing the at least one dental molding into the at least one receptacle, and excess adhesive exiting through the lateral opening in the circumferential surface, wherein the lateral opening protrudes at least in places in the coronal direction beyond an adjoining gingival margin of the prosthetic base; and F) subsequently curing the adhesive. The disclosure also relates to a device for producing dental prostheses using such a method, to a dental molding and to a dental prosthesis produced using such a method.

A method for producing dental prostheses in the form of partial or full dental prostheses, wherein each dental prosthesis has a prosthetic base and at least one dental molding and wherein the method comprises the following steps:

A) producing a prosthetic base from a gum-colored plastic material, wherein the prosthetic base is created with at least one receptacle for at least one dental molding and wherein a protruding pin is created in the at least one receptacle, or
providing a prosthetic base of a gum-colored plastic material, wherein the prosthetic base has at least one receptacle for at least one dental molding and wherein a protruding pin is arranged in the at least one receptacle;
B) producing or basally machining at least one dental molding, wherein a basal cavity for receiving the pin is created in the at least one dental molding or the at least one dental molding has a basal cavity for receiving the pin, wherein a lateral opening is created in a circumferential surface of the at least one dental molding, such that the basal cavity is accessible via the lateral opening in the circumferential surface of the at least one dental molding;
C) subsequently applying an adhesive into the basal cavity of the at least one dental molding or into the at least one receptacle of the prosthetic base or into the basal cavity of the at least one dental molding and into the at least one receptacle of the prosthetic base;
D) subsequently inserting the at least one dental molding into the at least one receptacle of the prosthetic base, such that the protruding pin is arranged inside the basal cavity;
E) subsequently pushing the at least one dental molding into the at least one receptacle, and excess adhesive exiting through the lateral opening in the circumferential surface of the at least one dental molding, wherein the lateral opening in the circumferential surface of the at least one dental molding protrudes at least in places in a coronal direction beyond an adjoining gingival margin of the prosthetic base;
and
F) subsequently curing the adhesive to definitively connect the at least one dental molding to the prosthetic base.
