The present invention relates to a method for producing a tailor-made implant intended to be implanted at an implantation site of a damaged bone part, the method comprising a step in which a 3D representation of a standard implant is superposed on a 3D representation of a damaged bone part by positioning said standard implant on an implantation site of the damaged bone part, in order, if necessary, to modify the dimensions and/or to adjust the shape of said standard implant, and also, if necessary, to modify the outer surface of said standard implant, which may be either the impression or substantially the impression of the outer surface of said bone part in the state prior to superpositioning of said implant, when the geometry of the damaged bone part is intended to be retained, or a functional outer surface, when said tailor-made implant is intended to be used at the interface of two bone parts cooperating with each other.
