Treatment
Agnathia treatment consists of rapid reconstruction using autogenous bone grafting to stop the further development of facial deformity. Mentoplasty, Bone grafting and cartilage onlay grafts, and Skin grafting are frequently used to restore facial symmetry. Distraction osteogenesis, which involves performing an osteotomy and attaching a distraction device to both portions of the mandible, is becoming more common. Early Orthodontics therapy in adolescents aids in the correction of malocclusion.[
