CRANIUM-ORIENTED MAXILA AND CONDYLE POSITIONING DEVICE

ABSTRACT

attention should be directed toward the preservation of preoperative condylar position during orthognathic surgery because their positional change may leads to postoperative skeletal relapse as well as TM joint problem. Various condylar positioning devices, therefore, have been introduced and utillzed in orthognathic surgery. Even though most of them provided us with improvement of surgical results, we also found some problems including limited indication, etc. For more accurately repositioning the maxilla and the mandible and its wide versatility, a newly designed maxilla and condylar positioning device based on the fixed part of cranium is introduced.
