Procedure for the determination of virtual dental restorations based on scanning data (D) of oral structures, in which - a database of models (DB) is used which, in each case, contains for different dental types a number of Parameterized dental models (M), the parameterization being produced by model parameters comprising position and / or shape parameters, and each dental model (M) being linked to a number of morphologically similar dental models (M) of the same type of tooth ( L), - for each type of tooth desired an optimal dental model (M) of a database (DB) is determined by an iterative procedure in which, first, it is chosen from the model database (DB) at minus an initial dental model (M) of a desired tooth type and then, starting with this initial dental model (M), a dental model (M) is tested at each iteration step (S) with respect to its qualitative value, being - for the individualization through the variation of model parameters, the group of current dental models (M) to be tested adjusted to the scan data (D) and calculating a qualitative value for said individualization, - for individualization through the variation of linked model parameters at least one dental model (M) with the dental model (M) to be tested also adjusted to the scan data (D) and an additional qualitative value calculated for said individualization, - selected based on the calculated qualitative values, if necessary , from the database of models (DB) a new dental model (M) to be tested for the type of tooth desired for the next iteration step (S), - the iteration interrupted upon reaching a quality criterion, - and finally , determined from the optimal tooth models (M) and scan data (D), a virtual tooth restoration (R).Procedimiento para la determinación de restauraciones dentales virtuales en base a datos de escaneado (D) de estructuras orales, en el cual - se usa una base de datos de modelos (DB) que, en cada caso, contiene para diferentes tipos dentales un número de modelos dentale
