The surgical treatment of skeletal anterior open-bite deformities with rigid internal fixation in the mandible.

The rationale for the surgical correction of skeletal anterior open-bite deformities by bilateral mandibular rotation osteotomy is presented. Results of this procedure in which rigid internal fixation is used are reported and show a very high degree of long-term stability. The procedure offers a useful alternative to the more common approach of posterior maxillary intrusion, which does not always address the cosmetic defect.
