Les insuffisances verticales postérieures de la mandibule : présentation d'une nouvelle technique de correction et étude rétrospective de 15 cas

In all fifteen cases, the occlusal plane was lowered in its posterior portion. Both vertical and sagittal occlusal results were stable. Elongation of the ramus as such is more difficult to demonstrate. Sagittal osteotomy of the mandibular rami with complete section of the pterygo-masseter sling lowers the bite plane in cases with mandibular posterior vertical deficiency. This technique avoids an external approach and belongs to the armamentarium aimed at treating this type of dysmorphosis.
