1. A method of repositioning performing an osteotomy on a maxilla, the method comprising:
attaching an osteotomy guiding implant to a first portion of the maxilla and a second portion of the maxilla while the maxilla is in a pre-operative shape whereby the first and second portions define a first relative position,
after the attaching step, cutting the maxilla so as to separate the first portion from the second portion;
after the cutting step, moving the first portion of the maxilla with respect to the second portion of the maxilla to achieve a post-operative shape of the maxilla whereby the first and second portions define a second relative position that is different than the first relative position; and
after the moving step, securing the second portion of the maxilla to the first portion of the maxilla with a bone fixation implant that is pre-operatively shaped to correspond to the post-operative shape of the maxilla,
wherein the guiding implant is pre-operatively shaped to correspond to the pre-operative shape of the maxilla.
