영문 초록

This case report illustrates a successful nonsurgical orthodontic treatment of two patients with a bilateral or unilateral scissors bite on the posterior teeth. The first patient was a 15-year-old boy who was diagnosed with Class II malocclusion with bilateral scissors bite. A mandibular lingual arch and a modified transpalatal arch (TPA) with preadjusted edgewise appliances were used to correct the bilateral scissors bite. After active treatment of 38 months, the facial profile was improved and good interdigitation with ideal incisor relationship was achieved. The other was a 20-year-old man who was diagnosed with Class I malocclusion with scissors bite on the right posterior teeth. Glass ionomer bite blocks were bonded on the left mandibular posterior teeth, and two miniscrews were inserted in the right mandibular buccal shelf for intrusion and uprighting of the posterior teeth. Intrusion and contraction of the maxillary arch were performed using modified TPA and miniscrews. After active treatment of 14 months, the unilateral scissors bite on the right side was corrected and appropriate occlusion was achieved. The treatment results suggest that lower lingual arch, modified TPA, miniscrews and bite blocks were effective for correction of the scissors bite on multiple posterior teeth without surgical intervention.
