Mandibular Symphyseal Distraction Osteogenesis―A Review

Mandibular symphyseal distraction osteogenesis (MSDO) is nothing but regular distraction osteogenesis (DO)performed at the symphysis wherein, the new bone formation occurs between bone segments that are gradually separated by incremental traction”.Treatment planning decisions in the transverse dimension are based on the mandibular arch width and form. Mandibular symphyseal distraction osteogenesis supplements orthodontic treatment to resolve mandibular anterior width deficiencies or dental crowding.This article focuses on indications, orthodontic preparation, surgical procedures, complications, long term effects and stability of mandibular symphyseal distraction osteogenesis.
