ABSTRACT:
The present invention provides an improved orthopedic system for the modification of the distance between the maxilla and zygoma. In a preferred embodiment, the system includes first and second footplates attached to an orthopedic device. The second footplate is attached to the zygoma, with the first footplate being mechanically coupled to the maxilla. This mechanical coupling is achieved either through attachment directly to the maxilla or by attachment to a construct wired to the patient's teeth. The orthopedic device, which may be a distractor, allows for modification of the distance between the maxilla and zygoma. The entire system can advantageously be placed intra-orally within a patient. In a preferred embodiment, the device does not increase in length upon activation. In another preferred embodiment, the second footplate is offset, allowing the actuator to be placed under the zygoma. Methods for using this novel orthopedic system are also disclosed.
