摘要

上顎後牙區常因上顎竇嚴重氣室化，人工植牙手術時操作不易且有鼻竇穿通之風險，因此人工植牙時需合併上顎竇提升術，並利用適當之骨移植或再生膜來確保上顎竇之提升；但以自體齒移植合併鼻竇提升通常不需要使用再生材料，因移植齒即可用來支撐已提升之上顎竇且移植齒其牙根周圍之細胞可扮演極佳之骨生成誘導作用，而達成理想之齒移植及骨再生。本病例提出以二次自體齒移植合併鼻竇增高術安全而有效地提升鼻竇，且快速而經濟的重建患者上顎後牙缺牙區進而恢復該區美觀及功能。

Because of the severe pneumatization of maxillary sinus, the sinus perforation may occur during the operation of dental implantation. Therefore, sinus lift procedure was invented to lift the sinus membrance safely and the bone grafts or membranes were usually applied to ensure the stability of the lifted sinus. On the other hand, the bone graft is not necessary used during autogenous tooth transplantation. Because the transplanted tooth can provide support for the lifted sinus membrane, and the periodontal ligament cells on its root may enhance the effect of osteogenesis. We provide a case who suffered from loss of maxillary posterior teeth, and then received twice procedures of auto- transplantation of tooth combined with sinus lift to restore her chewing function. Through these procedures, the patient's maxillary posterior area was restored fast and economically and then achieved a good long term result.
