A case of mandibular prognathism with open bite in a 18-year old girl was presented, which was treated by anterior alveolar osteotomy of the mandible combined with genioplasty. The procedure should be carefully planned with the use of analysis of dental casts, radiographs, split-photo techniques and other records, and has many advantages that will promise satisfactory results when the indication is correct, as shown in this case.
