Barrier membranes are critical to the success of guided bone regeneration (GBR). Though not directly involved in bone regeneration, barrier membranes hold bone graft materials at the surgical site during the slow process of bone regeneration and prevent the infiltration of fibrotic gingival tissues that would compromise new bone formation. Many options are available on the market, but membranes derived from placental tissues are gaining rapid adoption due to their unique biologic and handling properties. In this case series, a dehydrated human deepithelialized amnion-chorion membrane (ddACM) was used in combination with freeze-dried bone allograft (FDBA) for two-stage GBR procedures. Data from 1-year and 5-year follow-up appointments are presented, as well as predictable indications for the use of ddACM. Using ddACM with FDBA for GBR cases led to predictable bone regeneration with osseointegrated implants at 5-year postoperative visits.
