The present invention provides an improved rothopedic system (10) for the modification of the distance between the maxilla (21) and zygoma (22). In a preferred embodiment, the system includes proximal and distal footplates attached to an orthopedic device. The distal footplate is attached to the zygoma (22), with the proximal footplate being mechanically coupled to the maxilla (21). This mechanical coupling is achieved either through attachment directly to the maxilla (21) or by attachment to a construct which is then wired to the patient's teeth. The orthopedic device, which may be a distractor, allows for modification of the distance between the maxilla (21) and zygoma (22). The entire system can advantageously be placed intra-orally within a patient. In a preferred embodiment, the footplates are also detachable from the orthopedic device and are composed of a bioresorbable material, such that they will be absorbed by the patient's body. Methods for using this novel orthopedic system are also disclosed.
