Core Tip
Core Tip: Correction of severe skeletal class III malocclusion with facial asymmetry in adults through orthodontic treatment alone can be challenging. This case report demonstrates successful correction of a 27-year-old man's malocclusion with lower incisor extraction, intermaxillary elastics, improved super-elastic Ti-Ni alloy wire, and unilateral multibend edgewise arch wire. The use of these techniques, in conjunction with elastic chain closure of extraction sites, resulted in a more symmetrical facial appearance, acceptable overjet and overbite, and midline coincidence. This minimally invasive approach proved stable 3 years after treatment.
