中文摘要 | 自體牙齒移植(autogenous tooth transplantation)意指將同一個體口中無功用的牙齒由原處移植到另一無牙嵴區的手術方式。自體牙齒移植的最大優點,在於保存活體的牙周韌帶,維持黏彈性襯墊作用(viscoelastic cushion)和感覺器官、以調節牙齒運動與骨生成等生理機制。根據過去的文獻報告,以第三大臼齒作自體牙齒移植的存活率爲74-100%;最常見的失敗原因包括牙根黏連及牙根吸收;而嚴謹的治療計畫與審慎的移植技術是達成自體牙齒移植成功的重要因素。此篇文章報告一位二十三歲女性病患,以其自體齒右上顎第三大臼齒移植到右下第一大臼齒缺牙區之病例。根管治療與單一牙冠贋復後續完成。文中詳述手術過程、贋復時之注意事項以及兩年回診追蹤之結果,臨床與放射線檢查均顯示移植牙維持正常與健康的牙周韌帶。因此,除了傳統牙橋贋復物或人工植牙外,自體牙齒移植術在醫療與經濟觀點上提供了病患另一項治療的選擇。 |
英文摘要 | Autogenous tooth transplantation, or autotransplantation, is the surgical movement of a tooth from one site to another in the same individual. The most preferable advantage of autotransplantation is the viable periodontal ligament remained on the transplanted tooth for viscoelastic cushion, sensory organ, accommodation to tooth movement and regulation of osteogenesis. In previous literatures, the survival rate of autogenous tooth transplantation with third molars varied from 74-100%. Ankylosis and root resorption are the most common untoward events of failures. Thorough treatment planning and subtle technique are essential for successful autotransplantation. This case report describes a case of autogenous tooth transplantation from maxillary right third molar to the edentulous ridge of mandibular right first molar in a 23-year-old female. Endodontic therapy was performed and a single crown was subsequently placed. Patient complied with three-month recalls for the first year and every six months afterwards. At two years, both clinical and radiographic examination suggested normal and well maintained periodontal apparatus. Autotransplantation should be considered as an alternative to conventional prosthetic and implant rehabilitation from both therapeutic and economic standpoints. |
