利用腸骨移植及牙科植體進行贗復重建之病例報告

對於齒槽嵴嚴重缺損的症例，若要進行牙科植體的贗復，常需先進行骨移植的術式；而骨移植的來源以自體骨為最佳，但若缺損範圍巨大，則需由口外取得。本報告提出一利用腸骨移植合併牙科植體完成贗復的症例。患者為47歲的女性，右上犬齒至左上第二大臼齒是缺牙的狀態，咬合關係為安格氏第三級，經由臨床及X光檢查，發現其骨嵴的寬度及高度明顯不足，直接製作牙科植體支持固定式義齒將面臨軟組織及硬組織不夠的問題，經過討論，決定利用鈦金屬網及腸骨中的海綿骨進行骨嵴增術，4個月後，值入5根牙科植體，10個月後，進行贗復物的製作，以套疊式義齒的設計，改善臉型塌陷及齒槽嵴嚴重缺損的問題，進而恢復患者美觀及咀嚼功能。臨床上齒槽嵴嚴重缺損的重建，若要製作牙科植體支持之牙冠牙橋需進行多次硬組織及軟組織的重建，而本報告症例顯示，牙科植體支持之套疊式義齒也是一種有效的替代治療術式。

Bone grafting procedures is usually needed before placing dental implants in severe atrophic ridges cases. Autogeneous bone graft harvested extraorally have been used to restore large bone defect with good prognosis. This report described a case of combining iliac bone graft with dental implants for prosthetic rehabilitation. A 47-year-old female presented with maxillary partial edentulism and Angle's Class Ⅲ jaw relationship. From clinical and radiographic examination, extensive resorption from 13 to 27 edentulous area was found. Hard and soft tissue augmentation are required prior to fabricate implant-supported fixed prosthesis due to inadequate bone height and width. The patient accepted surgery of iliac bone graft reinforced with titanium mesh and then received 5 implants installation 4 months later. An implant-supported telescopic denture was designed to add lip support and improve esthetics. The final prosthesis was delivered 10 months after first graft surgery. In addition to implant-supported fixed partial denture, this case demonstrates implant-supported telescopic prosthesis can be an effective treatment alternative to restore patient's function and esthetics in severely resorbed edentulous ridge.
