摘要


引導骨再生術(guided bone regeneration, GBR)近年來已被證實用來解決骨頭缺損的問題包括根尖手術及植牙時骨頭缺損、骨量不足的問題。早期使用於GBR的阻隔膜都是不可吸收的再生膜,現在已逐漸被可吸收的再生膜取代。傳統上GBR都應用於二階段的人工牙根,近年來GBR也被應用於一階段的人工牙根來處理骨缺損的問題。本報告的目的是藉兩病例應用再生膜和骨移植材來處理根尖手術與人工牙根的骨缺損問題,除了組織切片檢查外還有長期臨床追蹤。

Recently, guided bone regeneration (GBR) has been proven to solve the bony defect including periapical lesion during endodontic surgery and implant surgery. Originally, the barrier membrane of GBR was nonabsorbable, it has gradually been changed to absorbable membrane now. GBR was traditionally applied in two-stage implant therapy, however, it is switched to one-stage implant surgery to solve bony defect simultaneously. This report is to present two long-term cases with biopsy using GBR to solve bony defect during periapical defect and implant surgery.
