Impact of Mandibular Symphyseal Distraction Osteogenesis (MSDO) on the Sagittal Dimension and Long-Term Skeletal stability.

Objective: To evaluate the long-term effects of mandibular symphyseal distraction osteogenesis (MSDO) on the correction of class II malocclusion correction and dental crowding.

Materials And Methods: Twenty-two patients received MSDO and presented class II malocclusion with transverse mandibular discrepancy. The authors collected data on 2 different cephalometric analyses.
