    • 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 proximal and distal footplates attached to an orthopedic device. The distal footplate is attached to the zygoma, with the proximal 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 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 and zygoma. 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.
    • 本发明提供了一种改进的矫形系统,用于修改上颌骨和合子之间的距离。 在优选实施例中,系统包括附接到整形外科装置的近端和远端足板。 远端足底板连接到合子,近端足底板与上颌骨机械联接。 这种机械联接可以通过直接连接到上颌骨上或者通过附接到构造物来实现,然后将其结合到患者的牙齿上。 可能是牵引器的矫形装置允许修改上颌骨和合子之间的距离。 整个系统可有利地被口内放置在患者体内。 在一个优选实施例中,脚踏板也可从矫形装置拆卸,并且由生物可再吸收的材料组成,使得它们将被患者的身体吸收。 还公开了使用这种新型矫形系统的方法。
