Abstract
BACKGROUND
Correcting severe skeletal class III malocclusion with facial asymmetry in adults through orthodontic treatment alone is difficult.
CASE SUMMARY
In this case report, we describe orthodontic treatment and lower incisor extraction without orthognathic surgery for a 27-year-old man with a transverse discrepancy. The extraction sites were closed using an elastic chain. The use of intermaxillary elastics, improved super-elastic Ti-Ni alloy wire, and unilateral multibend edgewise arch wire was crucial for correcting facial asymmetry and the midline deviation.
CONCLUSION
After treatment, the patient had a more symmetrical facial appearance, acceptable overjet and overbite, and midline coincidence. The treatment results remained stable 3 years after treatment. This case report demonstrates that a minimally invasive treatment can successfully correct severe skeletal class III malocclusion with facial asymmetry.
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.
