[Dental and skeletal malformations: 434 cases of II and III dental skeletal class. Our experience and review of the literature]

BACKGROUND: This study tests the patients who underwent to orthognatic surgery to compare the perioperatory treatment and the results with what related by international bibliography. METHODS: We have made a retrospective analysis on 434 patients affected by dentalskeletal malformations and surgically treated at the Department of Maxillo-Facial Surgery of the University of Rome "La Sapienza", from 1-1-1988 to 31-12-1997. We have examined these data: clinical evaluation of patient, pre and post-surgical orthodontic treatment, minimum age for surgical correction, surgical technique, use of osseus-synthesis with wire or RIF for mobile segment osseus stabilization, use of reference articular plaque and the possible association of additional surgical technique during the same time of maxillomandibular correction. We have made in all patients orthognatic surgery, which consist in osteotomy Le Fort I for upper jaw and sagittal osteotomy for mandible. RESULTS: In 25 patients was necessary remove the plaques and the screws which have made an infection. In 15 patients we have executed a subsequent operation for relapse of the dentalskeletal malformation. In other patients we have got a good functional and aesthetical result. CONCLUSIONS: From our study result that an exact presurgical analysis and a correct orthodontic-surgical treatment have permitted to obtain a good functional and aesthetical result in all patients.
