Abstract

A prospective and longitudinal study of 24 patients treated with mandibular retroposition and upper reposition of the chin by the techniques of modified branch sagital osteotomy and oblique osteotomy of the chin with pedicle of soft tissue in its anterior portion, from 1990 to 1997, was conducted. The posterior movement of the inferior incisor was associated with the anteroposterior movement of the lower lip and the soft pogonion in a ratio of 1:0.76 and 1:091 mm. The osteal pogonion was associated with the posterior movement of its soft homologue in a ratio of 1:086 mm. Point B accompanied its osteal counterpart in a proportion of 1:0.88 mm. Likewise, the vertical reduction of the chin decreased the length of the lower lip in 0.68 mm per every millimiter of reduction of the first;| whereas the soft pogonion upperly displaced 0.96 mm per each millimeter of reduction of the chin height. Other prognostic values were established for the mentolabial component that are important for cephalometric planning.
