摘要

傳統上全口無牙患者以全口活動義齒來恢復發音、咀嚼功能和美觀，但因為固持力不足，病人滿意度較差。口腔癌病人因為癌細胞進展迅速，為了能確實清除腫瘤，在手術時需要將手術範圍延伸到安全邊緣，改變了口腔軟組織及硬組織結構，影響病人在術後全口重建過程，義齒的穩定度、支持力及固持力不足的情形更嚴重，使得治療相較於口腔結構正常之病人不易。植體在治療此類病人提供了另一個選擇，其置放在顎骨中可以增加義齒的固持力、穩定度和支持力，因而提升病人滿意度。此篇報告為一病人經過口腔癌的手術治療和皮瓣重建後，因全口蛀牙及殘根移除全口所有牙齒並施行顎骨整形術，之後植入四個植體合併使用附連體來提高覆蓋式活動義齒的穩定性和下顎義齒的治療效果。經一年追蹤，外觀、功能、滿意度良好，無併發症發生，植體與骨頭也有良好之骨整合，特提出經驗報告。

Edentulous patients have common been replaced with dentures permitting improvement of speech, chewing function and aesthetics. But dental implants offer an alternative choice such as implant-supported overdenture. These implants are inserted into the jaws to provide more support, retention and stability of prosthesis. Here, we report a case who had received oral cancer surgical treatment and flap reconstruction. Owing to multiple caries, both upper and lower jaw had performed multiple retain roots removing and alveoloplasty. Afterwards four implants were inserted and these implants with Locator attachment to increase stability and therapeutic effect of lower denture. No complication was happened and good osseointegration of implants was showed as followed one year.
