1. A method for configuring a maxillofacial implant for osteosynthesis, the method comprising:
generating, using a computer, a three-dimensional model of a desired post-operative maxillofacial anatomy of a patient, the three-dimensional model indicating at least a simulated osteotomy that defines at least one cut that results in a second bone portion that is separated from a first bone portion within the three-dimensional model, the desired postoperative maxillofacial anatomy corresponding to a selected arrangement of the second bone portion in relation to the first bone portion, said arrangement comprising at least one or more of a translation and a rotation of the second bone portion in relation to the first bone portion;
defining, using a computer, on the three-dimensional model a first plurality of attachment points for the implant on the first bone portion and a second plurality of attachment points for the implant on the second bone portion,
wherein said first and second plurality of attachment points are defined on the three-dimensional model based on at least one of a thickness of a bone part and at least one location of one or more anatomical features of the patient; and
determining, using a computer, based on the first and second pluralities of attachment points, a monolithic three-dimensional structure for the implant that couples the first and second pluralities of attachment points in the three-dimensional model, wherein the monolithic three-dimensional structure for the implant has a shape that varies in each of three dimensions to arrange the second bone portion relative to the first bone portion in accordance with the desired post-operative orientation, each of at least one of the attachment points corresponding to an aperture for a bone fixation device in said structure.
