수직조절을 통한 골격성 성장기 II급 부정교합자의 치험례

The Treatment of Growing Class II Malocclusion Patient with Vertical Control

This case report is about a female growing patient with Class II malocclusion, showing 13 mm overjet, hyperdivergent skeletal pattern and mandibular retrusion. Treatment was planned in two stages. In the first stage, cervical headgear and twin block was used for maxillary growth restriction and mandibular forward positioning, followed by the second stage of fixed preadjusted edgewise orthodontic appliance for camouflaging the remaining skeletal and dental discrepancy using orthodontic mini-implant. We achieved satisfying results with harmonious face, Class I molar relationship with proper interdigitation, overbite, overjet, and midline coincidence.
