[Vertical augmentation of the alveolar process by distraction osteogenesis]

This article describes the treatment of a boy with Class II deep bite and hypoplasia of the alveolar process due to agenesis of the canines and premolars. At first, the occlusion has been adjusted by advancement of the mandible and opening of the bite after bilateral sagittal split osteotomy. Later, under local anaesthesia, a segmental osteotomy of the hypoplastic alveolar process has been performed. Distraction of the hypoplastic alveolar process has been achieved by orthodontic traction on the residual dentition in the segments. After sufficient augmentation of the alveolar process, 6 implants for two bridges have been placed.
