Generally caused by multiple births, early tooth trauma and dentition disorders and other factors.

In recent years, we applied the technique of filament arch correction to treat such malocclusion (occlusion) and achieved some results. This article through the thin wire arch correction treatment of 10 cases of incision on the clinical analysis of severe torsion on the correction of thin wire arch on the severe torsion
