Position of anterior teeth following surgical correction of prognathism.
20 patients who had all undergone surgical correction of progenia by sagittal split operation in the ascending ramus were chosen for a follow-up investigation 5 years after the operation. The patients could be divided into two groups showing either horizontal or vertical facial growth pattern. A cephalometric analysis was made of all the patients and the results of both groups were compared with one another. In particular the changes in the position of the anterior teeth and the amount of sagittal and vertical relapse were noted. It was noticed, that the type of measurable postoperative relapse was different in the two groups. Postoperative mandibular relapse is partially compensated by the position of the anterior teeth. Therefore the postoperative changes in the position of the anterior teeth are different in the two groups.
