Several bioabsorbable membranes have been proposed to exclude soft-tissue ingrowth and to stabilize the bone graft when guided bone regeneration (GBR) is performed. The properties of the various membranes differ slightly due to variances in composition and manufacturing processes affecting their handling and suitability for specific techniques. The aim of this article is to present a technique to perform GBR with the use of a sugar-crosslinked absorbable collagen membrane in conjunction with a dehydrated amnion/chorion membrane (dHACM). This technique can be used to perform GBR at the time of tooth extraction and for ridge augmentation of an edentulous site in preparation for future dental implant placement. The use of a collagen membrane in combination with a dHACM can facilitate stabilization of the bone graft and membrane by providing the benefits of a long-lasting bioabsorbable collagen membrane in addition to the unique benefits of an amnion/chorion membrane, which has been shown to provide growth factors to the surgical site that have potential to enhance regenerative outcomes.
已经提出了几种可吸收膜，用于在引导骨再生（GBR）时排除软组织向内生长并稳定骨移植物。由于组成和制造工艺的差异，各种膜的性能略有不同，这会影响其处理和对特定技术的适用性。本文旨在介绍一种使用糖交联可吸收胶原膜与脱水羊膜/绒毛膜（dHACM）联合进行 GBR 的技术。该技术可用于拔牙时进行 GBR，以及为未来种植牙放置做准备，对无牙部位进行牙槽嵴增高。胶原膜与 dHACM 联合使用可以通过提供持久的可吸收胶原膜的优点以及羊膜/绒毛膜的独特优点来促进骨移植物和膜的稳定，羊膜/绒毛膜已被证明可以向手术部位提供生长因子，从而有可能增强再生效果。
