Abstract
An implant for use in orthognathic surgery of a mandible may include a longitudinal plate member and a plurality of pre-configured guides coupled to the plate member. The longitudinal plate member is pre-bent to correspond to the post-operative shape of the mandible; and the guides are pre-configured to align the plate member with the mandible when the implant is positioned against the mandible after the mandible has been separated.
Claims9
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.
