應用引導組織再生術於骨內缺損治療－病例報告

嚴重的齒槽骨內缺損對臨床牙周病醫師而言是一項桃戰，較深的缺損若未施予全口的牙周病治療常容易造成更進一步的牙周破壞。針對骨內缺損的手術性治療包含有齒槽骨修整及再生手術。臨床上常使用的再生手術為引導組織再生術。本文提出一位廣泛性輕度及局部性重度慢性牙周炎病患在下顎第一大臼齒的近心牙根有接近根尖的骨內缺損病例，以翻瓣清創手術及徹底牙根整平術後，植入去礦化冷凍乾燥異體移植骨及聚乳酸可吸收再生膜。在評估牙周囊袋深度、附連高度及放射線檢查的骨充填影像後，手術的臨床效果及整體預後是令人滿意的。冀望藉由病例報告及臨床治療的文獻回顧，以提升此治療方法的可預測性。

Deep intraosseous defects represent a major challenge for the clinician. The intrabony defects in subjects who had not received systematic periodontal therapy have been substantiated as higher risks in disease progression. The surgical treatments of angular defects include osseous resective and reconstructive therapy. Guided tissue regeneration (GTR) is the most frequently documented reconstructive procedure. We provide a patient who was diagnosed as generalized mild and localized severe chronic periodontitis with a deep angular defect at the mesial root of her mandibular first molar. After flap elevation and thorough root planing, a polylactic acid biosorbable membrane and decalcified freeze-dried bone allografts were utilized in the defect. The clinical outcome evaluated by periodontal examination including probing depth, attachment level and radiographic bone f ill was satisfactorily. We hope to enhance clinical result of guided tissue regeneration in the angular defect and provide a treatment modality with high predictability.
