摘要

長期的缺牙造成對咬牙的挺出是缺牙病患中常見的臨床表現，在這樣的情況下容易造成不適當的咀嚼模式及容易造成食物鉗塞等問題，進而導致長遠的口腔機能損失，當出現嚴重的牙齒移位時，臨床上常常藉助矯正治療來重建咬合平面及缺牙區之牙冠高度，如此才能進行良好的補綴設計、改善整體的口腔狀況，而在矯正壓入的力學設計上，可以利用骨釘以及提供咬合墊高的方式來進行，本案例為嚴重的牙齒挺出之矯正治療，主要是以骨釘及活動假牙的設計來達成治療目標之病例報告。

Overeruption of maxillary molars because of loss of the opposing teeth creates occlusal interference and functional disturbances. To restore proper occlusion, intrusion of the overerupted molars becomes essential before reconstruction can be initiated. In this report, we present a simplified of the orthodontic appliances in conjunction with mini-implants and removable partial denture to intrude the overerupted molars. The purpose of using implants as skeletal anchorage was to eliminate the need for patient compliance for headgear wear and to overcome the difficulty resulting from the shortage of anchor teeth. The results showed that the biological responses of the teeth and the surrounding bony structures to the intrusion appeared normal and acceptable. Furthermore, the periodontal health and vitality of the teeth were well maintained even after a 3-year follow-up.
