摘要

本文回顧患者上顎前區牙床因創傷造成骨缺損均接受下顎技移植骨及人工植牙重建之治療。6位患者因車禍造成上顎齒脫落及牙床骨缺損，並接受階段性重建治療，包括(1)下顎技自體骨移植於上顎骨缺損區，(2)人工植牙手術，(3)軟組識處理，(4)假牙膺復。所有患者均於術後定期臨及X光片追蹤。6位患者共接受了16顆人工植牙鈴上顎前區，平均追蹤時間為4年，衍前患者均呈塌陷型牙床。治療完成後，其牙床型態、前庭角質化牙齦及長期膺復穩定性、植體周圍牙齦健康情況及結果令人滿意。本文提出針對上顎前區骨缺損之患者之階段性補骨及人工植牙膺復方法可做參考。

The use of manduibular ramus autogenous bone graft followed by implant surgery in 6 patients who had suffered from maxillofacial injury is reviewed. Six patients had severely deficient alveolar ridge and loss of teeth due to maxillofacial injury from motorbicycle accident. All cases underwent stepwise reconstructive procedures at the edentulous area with (1) autogenous bone graft from mandibular ramus, (2) implant surgery (3) soft tissue management (4) prosthesis rehabilitation. Postoperative follow-up consisted of clinical and radiographic examinations. Six patients with compromised ridges had 16 implant fixtures placed in the maxilla. The average time of follow-up was 4 years. Before surgery, all patients had severely deficient ridges with a compromised shallow vestibule of varying degrees. Satisfactory results were observed in regard to the immediate and long-term stability of the morphology of reconstructed ridge height and width, morphology of vestibule, the health of the pen-implant tissue, the stability of implant fixtures, and the functionality of the prostheses. The proposed reconstructive procedure offers a stable method of implant rehabilitation in cases with traumatic injury.
