Method of generating and modifying a virtual model of a denture, said denture comprising a region configured for the insertion of a restoration, the region being located in a gingival part of the denture, where the method comprises: obtaining at least one representation three-dimensional denture; - generating a virtual model of the denture (10) from said three-dimensional representation, where the virtual model of the denture comprises a gingival part, said gingival part comprising a virtual region corresponding to said region configured for the insertion of a restoration and at least part of the gum that surrounds said region; - obtain a virtual model of said restoration (14); and - modifying the gingival part of the virtual model of the denture based on the virtual model of said restoration (14), such that the virtual model of the restoration can be inserted virtually in said virtual region without any overlap between the volume of said restoration. virtual model of the restoration and the volume of said gingival part of the virtual denture model (10).Método de generación y modificación de un modelo virtual de una dentadura, comprendiendo dicha dentadura una región configurada para la inserción de una restauración, estando situada la región en una parte gingival de la dentadura, donde el método comprende: - obtener por lo menos una representación tridimensional de la dentadura; - generar un modelo virtual de la dentadura (10) a partir de dicha representación tridimensional, donde el modelo virtual de la dentadura comprende una parte gingival, comprendiendo dicha parte gingival una región virtual que se corresponde con dicha región configurada para la inserción de una restauración y por lo menos parte de la encía que rodea a dicha región; - obtener un modelo virtual de dicha restauración (14); y - modificar la parte gingival del modelo virtual de la dentadura basándose en el modelo virtual de dicha restauración (14), de tal manera que el modelo virtual de la restau
