Abstract
The invention relates to a method for producing denture parts or for tooth restoration. According to said method, to reconstruct a tooth requiring repair or a defective condition, at least some of the missing exterior surfaces of denture parts or tooth restorations are adapted to the existing residual tooth 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 generic 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 and the completion of the data record, the reconstructed denture part or the reconstructed tooth restoration is machine-manufactured.
