Effect of Accurate Prediction of Mandibular Molar Position in Orthognathic Surgery.
J Surg Pak Jan ;6(3):2-6.

This prospective study was carried out to evaluate the effect of accurate prediction of mandibular molar position in orthognathic surgery at the Center for Dentofacial Deformities, New York University College of Dentistry, U.S.A. during 1994-1997. Twenty patients with Lefort-1 osteotomy with impaction were investigated. Two methods were used to simulate rotation of mandible, the standard method with center of rotation of mandible being center of condyle and the other method with the center of rotation of mandible being 14.9mm below and 5.0 mm behind the superior mid surface of the condyle in sagittal view. Eight variables were evaluated but only one, that is the most anterior point of the lower molar horizontally, came out significantly different. It was concluded that the position of mandibular molar could not be significantly predicted vertically and horizontally and there was no significant difference in the position of lower molar with both the methods of prediction.
