Disclosed is a method for manufacturing a dental prosthesis, including a step of digitally designing a dental prosthesis model from a replica model of a patient's teeth, a step of generating a jaw portion model including the teeth replica model and the dental prosthesis model, a step of manufacturing a jaw portion including a positioning member based on the model of the jaw portion, and a step of positioning the jaw portion on a shell of a shell mold by the interaction of the positioning member of the jaw portion with a complementary positioning member arranged in the shell. Also disclosed is a shell mold used in such a method.

Disclosed is a method for manufacturing a denture including a denture base and at least two artificial teeth arranged in the denture base, wherein the method includes the steps of obtaining the denture base; manufacturing the at least two artificial teeth with a common placement support connected to the at least two artificial teeth for keeping the at least two artificial teeth in a desired relative arrangement, arranging the at least two artificial teeth on the denture base with the common placement support connected to the at least artificial teeth, attaching the at least two artificial teeth on the denture base, and removing the common placement support. This further ensures proper placement of the artificial teeth in the denture base of a denture.

Method and system for the construction of a total dental prosthesis, wherein the shapes of the upper and lower jaw bases taken in the plastic material are digitized and stored as a digital prosthesis model in a data-processing device, and the upper and lower jaw prosthesis bases are produced from dental materials according to the digital prosthesis model by ablative or constructive methods.

There is disclosed a method for manufacturing a denture comprising an artificial gingiva surface, a seating surface facing at least a part of the gingiva surface when placed in the mouth of a patient, at least one tooth receiving hole provided in the artificial gingiva surface and extending through to the seating surface and an artificial tooth arranged in the tooth receiving hole, The method comprises printing an intermediate denture base comprising the artificial gingiva surface, the at least one tooth receiving hole for receiving the artificial tooth, arranging the artificial tooth in the at least one tooth receiving hole, fixing the intermediate denture base in a milling machine, and milling the denture comprising providing the seating surface by removing at least a part of the tooth extending through the tooth receiving hole. This provides an improved manufacturing process of denture.

The invention relates to a method for producing a prosthesis or partial prosthesis based on digital data, using multiple teeth present in a dental arch (14) and a prosthesis base to be produced, characterized in that the prosthesis base is rough-milled by means of a milling tool, i.e. is milled in a first step, and in that the prosthesis base present as a semi-finished product, in particular in regions of the prosthesis base on which the teeth and the prosthesis base abut against each another and/or are to be bonded to each other, is partially milled, i.e. is milled in a second step, by means of an in particular different milling tool, thereby being brought to a target height which corresponds to the desired bonding gap between the prosthesis base and the tooth or dental arch (14).

A tooth cutting guide or tooth ridge lap guide for processing at least one prefabricated artificial tooth from a set of prefabricated artificial teeth using a subtractive processing method, the tooth cutting guide comprising a base body, at least one retainer for receiving and positioning the at least one prefabricated artificial tooth, which is formed in the base body, wherein an inner surface of each of the at least one retainer form fits to a first surface area of one of the at least one prefabricated artificial tooth from the set of prefabricated artificial teeth, and at least one through hole which is located in the at least one retainer, wherein the at least one through hole exposes at least a part of a basal surface or an occlusal surface of the one of the at least one prefabricated artificial tooth if inserted into the corresponding retainer.

Also disclosed is a method for manufacturing at least one tooth cutting guide or tooth ridge lap guide for processing prefabricated artificial teeth and a method for producing a denture using first said method.

The invention relates to a method for producing a dental prosthesis with: A) provision of a milling body and a prosthesis base preform with a holding structure (34); B) production of a connecting surface in the milling body by a subtractive CAM method; C) production of mating holding structure which fits with the holding structure in the surface of the milling body or said mating holding structure is present; D) attachment, spaced via the holding structure, of the prosthesis base preform to the mating holding structure, wherein an interspace is obtained; E) introduction or application of a fluid polymerizable plastic into the interspace; F) curing or partial curing of the plastic to yield a plastics material in the interspace which connects the prosthesis base preform to the milling body; and G) subtractive machining of the plastics material, the prosthesis base preform and the milling body by a CAM method in accordance with a model of the dental prosthesis.

The invention also relates to a dental prosthesis produced with such a method and a device for implementing such a method.

The invention relates to additively manufactured dental devices comprised of a denture base and at least one removable bracing body joined at specific locations to the denture base. The invention also relates to methods of using these additively manufactured dental devices in the fabrication of dental prostheses.

Removable denture data of a removable denture is produced, and disk frame data of a disk frame in which the removable denture is accommodated is produced, thereby building the disk frame based on the disk frame data. Next, a resin disk in which artificial teeth are embedded is produced by arranging the artificial teeth in the disk frame and curing a base resin, and a denture base is milled by milling the resin disk based on the removable denture data, thereby manufacturing the removable denture in which a base side of the artificial teeth is embedded in the denture base. As a result, artificial teeth having an excellent aesthetics may be used, it is possible to firmly join the artificial teeth and the denture base to each other, and it is possible to manufacture a removable denture with a favorable restoration accuracy of the artificial teeth.
