Abstract
Retraction of anterior protruded maxilla based on the mechanical principle of distraction osteogenesis by using a compression device and mini-screw implants will offer better facial esthetic and reduce the length of treatment over the conventional orthodontic.
• The primary objective
Anterior maxillary segment retraction by compression osteogenesis
• The secondary objective
Assessment of facial esthetic and occlusion.
In combining with orthodontic the therapy can markedly reduce the duration of treatment over the conventional orthodontic treatment
