Method for producing a dental prosthesis composed of an infrastructure made of at least one first material covered in part by a covering material different from said at least one first material, the method having the steps in which an infrastructure (1) is formed by any given method, a digital model of the desired shape of the final dental prosthesis to be obtained is formed, for example, by CAO the covering material is deposited on the external surface of the infrastructure in an excess quantity in relation to the digital model of the final dental prosthesis to be obtained, so as to thereby obtain an intermediate template the assembly composed of infrastructure and of excess covering material is positioned and fixed in the machining unit the position of the infrastructure in the machining unit is determined and the excess covering material is machined in order to obtain the desired shape of the final prosthesis, characterized in that a holding system (2) is provided which holds the assembly composed of infrastructure and of covering material in the machining unit and which is fixed to the assembly in such a way as to leave the internal surface of the infrastructure at least partially free.Procédé de fabrication dune prothèse dentaire composée dune infrastructure en au moins un premier matériau recouverte en partie dun matériau de recouvrement différent dudit au moins un premier matériau, le procédé comportant les étapes dans lesquelles on réalise une infrastructure (1) par un procédé quelconque, on réalise un modèle numérique de la forme souhaitée de la prothèse dentaire finale à obtenir, par exemple par CAO on dépose sur lextrados de linfrastructure le matériau de recouvrement en une quantité en excès par rapport au modèle numérique de la prothèse dentaire finale à obtenir pour ainsi obtenir un gabarit intermédiaire on positionne et on fixe lensemble infrastructure-matériau de recouvrement en excès dans lunité dusinage on détermine la position de linfrastructure d
