RESUMO
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.
