Fecha de publicación: -- Fuente: Wipo "digitalization" The invention relates to a computer-implemented method for providing a set of layer-specific molding matrices (101, 111) for reconstructing layer-by-layer one or more teeth (130; 172) of a set of teeth in a patient's oral cavity. The set of layer-specific molding matrices (101, 111) comprises two or more layer-specific molding matrices (101, 111). Each of the layer-specific molding matrices (101, 111) is configured for being arranged on the set of teeth and for casting a different layer of the one or more teeth (130; 172) to be reconstructed with a layer-specific reconstruction material (152) inserted into the respective layer-specific molding matrix (101, 111). The respective layer-specific molding matrix (101, 111) defines a 3D geometric form of the respective layer (132, 134, 136) being casted.
