In 1932 Wassmund introduced LeFort I osteotomy and since that time it has become the “work horse” for the treatment of malocclusion, especially open bite. There are many technical nuances associated with the surgery and orthodontic preparation that will be discussed. When surgery is coordinated with orthodontic care, the long-term outcomes can be favorable. Appropriate diagnosis and patient selection are the keys to success as well as close interdisciplinary working relationships between surgeons and orthodontists.
Recognize disproportionate jaw growth related to open bite.
Apply coordinated orthognathic principles to managing open bite with maxillary or bimaxillary surgery combined with orthodontic treatment.
Understand the importance of physiological adaption to jaw repositioning surgery combined with orthodontic treatment.
