Osseoseal Collagen Membrane, a collagen membrane derived from purified porcine pericardium, is a great option for GBR when looking to contour and “seal” off particulate bone graft in a self-containing defect. The following case demonstrates how to properly handle and apply the Osseoseal Collagen Membrane.
An implant was placed in site #7 with an existing buccal bone defect (Pictures 1 & 2). Prior to placing the bone graft over the implant, the membrane is measured and trimmed and tucked under the palatal flap trying to avoid wetting the entire membrane (Picture 3). The particulate bone graft (DALI Classic Cortical Cancellous Mix) is placed over the implant surface to restore the defect (Picture 4). The membrane is folded over the crest and onto and slightly beyond the particulate bone graft while slowly dropping saline onto the membrane (Picture 5). This enables the membrane to contour and drape over the graft and “seal” the graft off from the surrounding soft tissue (Picture 6 and 7). Sutures are then used to achieve primary closure over the GBR site (Picture 8).
