Predictable coverage of exposed root surfaces and the corresponding treatment of gingival recession defects remain important objectives of periodontal therapy. A variety of techniques have been developed during the past several decades to address this common clinical challenge. Traditional surgical approaches have been relatively successful in achieving root coverage. Attempts have been made recently to achieve root coverage with surgical techniques based on the principles of guided tissue regeneration, using resorbable and nonresorbable materials. The learning objective of this article is to present case documentations of root coverage, using a resorbable collagen barrier. The results achieved illustrate the potential of this material in the treatment of gingival recession. The biologic properties of collagen as a barrier material, the surgical approach, and the principles of case selection are reviewed.
可预测地覆盖暴露的牙根表面以及相应地治疗牙龈退缩缺损仍然是牙周治疗的重要目标。在过去几十年中,已经开发出多种技术来应对这一常见的临床挑战。传统的手术方法在实现牙根覆盖方面相对成功。最近,人们尝试基于引导组织再生的原理,使用可吸收和不可吸收材料的手术技术来实现牙根覆盖。本文的学习目标是展示使用可吸收胶原屏障进行牙根覆盖的病例记录。所取得的结果说明了这种材料在治疗牙龈退缩方面的潜力。本文回顾了胶原作为屏障材料的生物学特性、手术方法以及病例选择原则。
