中文摘要 | 此病例報告提出一成年骨性二級異常咬合合併中度齒列擁擠之掩飾性治療。一位28歲女性前來求診,主訴為上下唇明顯前突及暴牙。臨床檢查顯示患者側面觀為凸臉、下頭後縮、上下前牙突出合併大量的垂直及水平覆咬,咬合關係呈現安格式二級一類異常咬合。為了同時改善臉部外觀、上下唇前突、大量水平覆咬、齒列擁擠及二級咬合,矯正治療計畫為拔除四顆第一小臼齒並合併迷你植體進行上額後牙遠心移動,以同時改善臼齒關係及顏面美觀。治療結果顯示臉部輪廓改善、齒列整齊以及良好的咬合關係。本篇亦就骨性二級咬合相關的治療策略、掩飾性矯正治療及使用迷你植體速心移動臼齒應考量之矯正機制、生物力學作相關探討。 |
英文摘要 | A case report describes the camouflage treatment of an adult patient with skeletal Class II jaw base relationship and moderate crowding. A 28-year-old woman presented with chief complaints of protrusive lips and upper front teeth. The clinical examination showed a convex facial profile, retrognathic mandible, excessively proclined upper and lower incisors, large overbite and overjet and a Class II division 1 malocclusion. To correct the facial profile, lip protrusion, large overjet, space deficiency and approximately full Class II relationship, distal movement of the maxillary first molars using miniscrew anchorage along with extraction of the maxillary and mandibular first premolars was planned. The treatment results showed great improvement of facial profile, well aligned dentition and satisfactory occlusion. The mechanism, biomechanical consideration, and factors associate with Class II orthodontic camouflage treatment and molar distalization with miniscrews were discussed. |
