The invention relates to a method for producing denture parts or for tooth restoration. According to said method, to reconstruct a tooth requiring repa ir or a defective condition, at least some of the missing exterior surfaces of denture parts or tooth restorations are adapted to the existing residual too th material and/or the opposing teeth and/or the position of the neighbouring tooth and/or the occlusion position, by means of the optimisation of a gener ic dental-model data record of the desired tooth type, thus varying the linear factors of at least the most important components, (determined from the electronic data records of a larger number of measured tooth surfaces by primary axis analysis methods), in such a way that the selected optimisation criteria are fulfilled by the minimisation of an error function. After the successful adaptation of said surfaces to the residual occlusion position an d the completion of the data record, the reconstructed denture part or the reconstructed tooth restoration is machine-manufactured. |
