title: Surgical treatment of the open bite deformity. Surgical correction of combined mandibular prognathism and open bite by oblique sliding osteotomy of the mandibular rami.
abstract: Treatment of open bite deformity combined with a prognathic mandible using the oblique, sliding osteotomy of the mandibular rami has been followed for 2 1/2 years to evaluate the final outcome of the operation. The clinical and radiographic examination during the control period show a remarkably stable result with a relapse magnitude the same or slightly less than that for a straight, set-back procedure. A certain dental compensation occurs during the skeletal relapse. The thought of creating a certain "freedom-space" in the muscular fibres during the set-back procedure, thus facilitating closure of the open bite is proposed. Surgical correction of the anterior open bite today is otherwise most frequently focused on solutions with maxillary le Fort I or subapical procedures to ensure minimal influence from the jaw muscles.
