摘要

引導骨再生術應用於牙周病治療及植牙已行之多年。一般而言如果沒有過早露出再生膜的話，它的效果是可以預期的而且非常好。然而一旦再生膜過早露出，它的效果就大打折扣。本文的目的在報告利用小手術翻瓣來處理應用於引導骨再生術中過早露出的再生膜。兩病例在引導骨再生術後兩星期拆線時即發生再生膜露出，對於露出的再生膜用0.12% chlorhexidine漱口水維持清潔，術後四星期利用一個小手術翻瓣去除露出部份的再生膜而未被感染的部份仍保留，臨床效果顯示良好。本報告提供引導骨再生術中過早露出的再生膜的變通解決辦法，較之過早露出時摘除全部的再生膜效果要好的多而且手術方法簡易。

Guided bone regeneration (GBR) has been used in periodontics and implant dentistry for many years. Generally, the results are predictable and excellent if there is no early exposure of the barrier membrane. Once the barrier membrane becomes exposed, the results of the GBR procedure becomes unpredictable and difficult to correct and keep clean by the therapist as well as compromises good oral hygiene by patients. The purpose of this paper is to present a min or surgical flap procedure to correct the early exposure of a barrier membrane. Two cases were reported which had early membrane exposure after suture removal in two weeks. The exposed membranes were carefully treated with a 0.12% chlorhexidine mouthrinse. The exposed part of membrane was removed using a miniflap 4 weeks postoperatively. The clinical results were excellent after removal of the exposed portion of the membrane. This report provides an alternative treatment modality of an early exposed non-resorbable membrane. It only requires removal of the exposed portion of the membrane rather than removal of the whole barrier membrane. Intervention with this minor surgical method makes cases of early membrane exposure more predictable in attaining optimal GBR results.
