편측 가위교합을 동반한 성장기 II급 부정교합 환자에서 Double Plate를 이용한 치험례

Class II Adolescent Patient with Unilateral Scissors Bite Using Double Plate Appliance: A Case Report

Skeletal Class II with transverse maxillo-mandibular arch discrepancy is a challenging malocclusion. Transverse harmony between both arches is particularly important for sagittal correction and good balance of the occlusion. A 14-year-old boy with chief complaints of chewing problem on the left side is presented in this report. He had a scissorsbite on the left side with both sides showing Class II molar relationship. Double plate was used for constriction of the maxillary molar width and expansion of the mandibular molar width, and sagittal correction as well. After the first phase of the treatment, fixed orthodontic appliances were used to align the dentition and to improve the maxillomandibular interdigitation.
