摘要

自體齒移植術可利用智齒作為供給齒，解決缺牙的問題。本病例報告之患者為27歲男性，因左上後牙區不適感前來本院就診，經檢查發現左上顎第三大臼齒有大範圍銀粉填補合併牙齒斷裂，右上顎第三大臼齒仍留存。診斷為左上顎第三大臼齒已根管治療及牙齒斷裂。和患者經討論後，決定手術拔除左上顎第三大臼齒，並以右上顎第三大臼齒作為移植齒進行自體齒移植術。因移植齒為封閉根尖，術後進行根管治療，復原良好，無臨床症狀或放射學透性影像病灶，後續進行復牙冠製作，術後兩年追蹤無任何症狀。

In autotransplantation, the third molar can be selected as a donor tooth to treat patients with missing tooth problems. In this case, a 27-year-old male suffered from discomfort at upper left posterior area. With clinical examination, left maxillary third molar was found with large amalgam filling combined with tooth fracture, biting pain and percussion pain were also observed. Left maxillary third molar was diagnosed as previously endodontically treated and split tooth. After discussion with patient, we used right maxillary third molar as a donor tooth for autotransplantation after extraction of left maxillary third molar. After autotransplantation and endodontic treatment of the donor tooth, fair healing was observed and no discomfort was noted for 2 years follow up.
