Combined mentalis weakening and periosteal flaps in mandibular anterior alveolar corticotomy-assisted orthodontics with bone grafting

Abstract

Inter-alveolar augmented corticotomies with bone grafting may be used before orthodontic treatment in cases of root out or in major proclination movements in the lower anterior region. Bone graft particle spreading with reduced confinement and strong labial muscle contractions may cause graft resorption. Herein we describe a combined orthodontic corticotomy technique involving periosteal flap grafting confinement and a surgical muscle-weakening flap to avoid resorption.
