A method for producing a dental prosthesis, and a dental prosthesis made according to the method, the method having the following chronological steps:

Device and method for holding prosthetic teeth

Method for producing a three-dimensional model of at least a partial jaw comprising: fully-automatic shaping of at least one recess for accommodating a laboratory analogue into the alveolar ridge of the model using three-dimensional scanning data and shaping the depth, position, and orientation of the at least one recess such that the crestal end of the laboratory analogue inserted into said recess coincides with the crestal end of the dental implant in the jaw; or fully-automatic shaping of at least one vestibular, lingual or palatinal feed-through through the model into the at least one recess using three-dimensional scanning data and arranging the feed-through such that the crestal end of a laboratory analogue coincides with the crestal end of the dental implant in the jaw when the laboratory analogue is fixed in place with a pin inserted through the feed-through in the model into an opening in the laboratory analogue.

Methods for producing a laboratory analogue for dental implants

The invention relates to a method for producing a denture base semi-finished product with the following steps: 1) Recording and digitalizing the oral cavity situation of a patient, wherein a digital three-dimensional oral cavity model of the patient is produced, or providing a digital three-dimensional oral cavity model of the oral cavity situation of a patient; 2) Implementing a first calculation in which a digital three-dimensional first model (A) of a denture base is calculated, wherein the oral cavity model of the oral cavity situation is used as a basis for the first calculation; 3) Conducting a second calculation, in which a digital three-dimensional second model (B) of a denture base semi-finished product is calculated from the first model (A) of the denture base, wherein volume is added at least in sections to the three-dimensional model (A) of the denture base; and 4) Producing the denture base semi-finished product with a Rapid Prototyping method, wherein with the Rapid Prototyping method, a CAM method is used and the digital three-dimensional second model (B) of the denture semi-finished product is used as the basis for the CAM method. The invention also relates to a device for implementing such a method and a denture base semi-finished product produced using such a method.

Method for producing a denture base semi-finished product

The invention relates to a process for producing a dental prosthesis with the chronological steps: The invention also relates to a dental prosthesis produced using such a process and a kit to carry out such a process.

Method for producing a dental prosthesis

The invention relates to a temporary dental prosthesis for determining abrasion facets, having at least one prosthetic tooth, in which at least the occlusion surface of the prosthetic tooth or at least one of the prosthetic teeth is made of a material that is abradable such that, within a maximum of 12 weeks of use as a dental prosthesis by a patient, abrasion facets are produced on the prosthetic teeth and are suitable for ascertaining the chewing movements of the jaw of the patient. The invention also relates to a method for determining the chewing movement of a set of teeth from measured abrasion facets, in which a temporary dental prosthesis made of an abradable material is inserted in a patient, and to a method for producing a final dental prosthesis.
