Nonextraction treatment of a class III malocclusion case using mini-screw-assisted lower molar distalization

Abstract

Mini-screw assisted lower molar distalization was planned for a present mild Class III malocclusion case. Two mini-screws were inserted into the available inter-root area: one on the left, and the other on the right side in the posterior region in the mandible. Distalization of lower molars, premolars and canines were achieved. Orthodontic treatment lasted approximately 2.5 years with 1 year of molar distalization. Minimal relapse was seen in the postretention period. Dentoalveolar changes with mini-screw assisted lower molar distalization are reported in the present case.
