Role of anterior segmental osteotomy for management of dento-osseous deformities
Background: The procedures of anterior segmental osteotomy are stable, versatile and can be undertaken for multiple deformities affecting the anterior portion of jaws.
Objectives: To describe indications in which anterior segmental osteotomy alone can correct maxillomandibular deformities and if adjunct surgery is needed or not. Orthosurgical planning with cephalometric predictions of those deformities of anterior portions of jaws which can be corrected by anterior segmental osteotomy. Achieve occlusion and periodical follow-up of the operated patients to analyze changes produced by surgery and stability of results clinico-radiographically.
Material and methods: The study consisted of 16 selected patients of which 9 were female and 7 were male. The ages ranged from 17 to 25 years. Patients with skeletal deformity along with malocclusion which was too severe to be corrected orthodontically were selected. History and examinations were carried out as per standardized protocol. The parameters were laid down only after reviewing the literature and discussion with an orthodontist as presurgical and postsurgical orthodontics are considered mandatory for these cases.
Results: Presurgical orthodontics is required for decompensating the intradental and interdental relationship. Cephalometric studies should be mandatory. Model surgery and construction of an occlusal wafer was of great help in achieving the desired position of osteotomized segments intraoperatively.
