Abstract
- Transverse skeletal deficiency is a common clincal problem associated with narrow basal and dentoalveolar bone. The clinical characteristics of transverse deficiency presents with anterior crowding and posterior buccal crossbite. Orthodontic expansion, using lip bumper and functional devices, was recommanded for younger ages. However, expansion of lower anterior area in older patients is unstable and tends to relapse toward the original dimension. Distraction osteogenesis is a unique form of clincal tissue engineering and biologic process of new bone formation between bone segments that are gradually separately by incremental traction. Distraction osteogenesis was considered that great potential for correcting transverse mandibular deficiencies. In this paper, a case of treated transverse deficiency patients with distraction osteogenesis using tooth-borne and tooth & bone-borne distractor is presented.
