The complications include sensory disturbance, jaw fracture, excessive bleeding, condylar positional changes and loss of pulp vitality. Few surgical procedures are as satisfying for the surgeon and patient as a well-done orthognathic surgery. On the other hand, the patient is more satisfied with the result than who are treated with only orthodontic treatment especially in severe deformity case.
