Abstract

The aim of this study was to assess the accuracy of Quick Ceph and its ability to prepare prediction profiles by using the records of 16 patients who had mandibular advancement via sagittal split osteotomy. The results of this study showed that Quick Ceph tended to overestimate horizontal landmark position and underestimate vertical changes. However, the mean differences and standard deviations were less than values reported for manually prepared prediction profiles. If this imprecision is taken into account during treatment planning for mandibular advancement, then Quick Ceph offers a reasonably accurate method of prediction without imposing heavily upon time or artistic licence.
