摘要


引導組織再生(GTR)的觀念應用在牙周組織再生的治療已有將近20年的歷史。這段期間,陸續有不同的牙周再生材料上市,以期改善牙周組織再生的臨床效果;然而,這些材料各有不同的優點及缺點。硫酸鈣(plaster of Paris)在骨科被用來作骨內缺洞的充填動物實驗及臨床的治療,已有100多年的歷史。硫酸鈣具有很好的生物相容性、操作簡單、易於取得、材料費用不高、被吸收的速度與骨形成的速度相當。脫鈣冷凍乾燥同種異質骨(DFDBA)的應用始於1960年代,一直以來被認為在對牙周骨頭缺損的治療是一種安全有效的材料。本臨床病例報告是根據1992年Dr. Sottosanti所提出的方法,同時使用硫酸鈣及DFDBA治療牙周骨內缺損及二級根叉侵犯的結果顯示硫酸鈣結合DFDBA當作複合移植體並另外以硫酸鈣為隔離膜,術後均有良好的組織反應,術後6個月X光並有骨充填產生,顯示硫酸鈣合併DFDBA是施行GTR的一種可選擇的材料。

The application of guided tissue regeneration in periodontal treatment has been for 20 years. Kinds of periodontal regeneration devices were developed to achieve the goal of periodontal regeneration. Calcium sulfate (plastic of Paris) has been utilized as a bony defect filler by orthopedist for 100 yeas. It has good biocompatibility, easy manipulation, plenty of source, inexpensiveness and its resorption rate is comparable to that of bone formation. DFDBA has been considered as a safe and effective material for treatment of periodontal bony defect. In this clinical report, the procedures were adopted from Dr. Sotosanti in 1992, the application of both calcium sulfate and DFDBA to treat periodontal intrabony defect and class II furcation involvement. The results show calcium sulfate combined with DFDBA has a good tissue reaction and radiographic bone formation 6 months after surgery. It indicates that calcium sulfate may be a choice of GTR material in periodontal therapy.
