Vertical ridge augmentation using space-making frameworks and graft materials offers an ideal balance between the expected amount of bone gain and postoperative complications compared with other interventions.^4,5 The rationale of GBR is based on the creation of a sheltered, soft tissue cell-excluding area to promote osteoblast migration.⁶ Dimensionally stable structures such as titanium-reinforced non-resorbable membranes or non-occlusive titanium meshes support vertical dimensions more reliably than cell-occlusive but pliant absorbable membranes. Although d-PTFE is a commonly used nonresorbable barrier material, it may exhibit subpar tissue adhesive properties that risk flap integrity.⁷ Innovators have developed materials that better approximate the periosteum to the underlying graft. Our study utilized a RPM perforated by macropores that theoretically improves vascularization by permitting direct contact between the periosteum and the bone grafts. To our knowledge, this is the first human case series to record the use of RPM for VBA.
