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.

1. A method for determining the chewing movement of a dentition from measured abrasion facets, the method comprising inserting a temporary dental prosthesis made of an abradable material in a patient, and after a maximum of 12 weeks of use of the temporary dental prosthesis, measuring the abrasion facets on the temporary dental prosthesis, and calculating the chewing movements of the dentition of the patient from the measured abrasion facets. 2. The method according to claim 1, comprising producing the temporary dental prosthesis by a rapid prototyping method or by an abrasive method. 3. The method according to claim 2, comprising determining a centric occlusion prior to producing the temporary dental prosthesis. 4. The method according to claim 1, comprising measuring the abrasion facets of the temporary dental prosthesis after said use using a scanner, determining a position, depth, and/or shape of the abrasion facets using a computer, and calculating the patient's chewing movements from data thus obtained relating to the abrasion facets. 5. The method according to claim 4, comprising measuring the abrasion facets of the temporary dental prosthesis after said use using a scanner, determining a position, depth, and/or shape of the abrasion facets using a computer by comparing a recording of the temporary dental prosthesis prior to said use, or of a CAD model of the temporary dental prosthesis prior to said use forming the basis for production of the temporary dental prosthesis, with the temporary dental prosthesis after said use. 6. A method for producing a final dental prosthesis including prosthetic teeth, comprising applying a method according to claim 1, calculating a position and an orientation of the prosthetic teeth of the final dental prosthesis on the basis of data relating to the patient's chewing movements ascertained using the temporary dental prosthesis, and producing the final dental prosthesis on the basis of this calculation. 7. A method according to claim 6, comprising producing the final dental prosthesis using a CAD-CAM method. 8. A method according to claim 1, wherein the temporary dental prosthesis has least one prosthetic tooth, wherein at least an occlusion surface of the at least one prosthetic tooth is made of a material that is abradable such that, within a maximum of 12 weeks of use as a temporary dental prosthesis by a patient, abrasion facets are produced on the at least one prosthetic tooth and are suitable for ascertaining chewing movements of a jaw of the patient, wherein a material thickness of at least 0.1 mm is eroded on at least one of the abrasion facets produced within a maximum of 12 weeks. 9. A method according to claim 1 comprising, after a maximum of 4 weeks of use of the temporary dental prosthesis, measuring the abrasion facets on the temporary dental prosthesis and calculating the chewing movements of the dentition of the patient from the measured abrasion facets.
