Fuente: Wipo "digitalization" One aspect of the present application provides a computer-implemented method for generating a 3D digital model of gingiva, comprising: obtaining a 3D digital model of gingiva in a first state; and performing deformation process on the 3D digital model of the gingiva in the first state based on its deformation control points and deformation control points of a 3D digital model of crowns in a second state, to obtain a 3D digital model of the gingiva in the second state, wherein corresponding deformation control points of 3D digital models of the crowns and the gingiva in the same state coincide.
