Synthetic mineral collagen composite bone graft with ribose cross linked collagen membrane for lateral ridge augmentation

A combination of calcium phosphate-based mineral with carbon apatite structure and type 1 collagen derived from bovine Achilles tendon has been introduced for augmentation of alveolar ridge and periodontal defects. Carbon apatite structure of mineral mimics natural bone in terms of resorption and remodeling, while collagen provides three-dimensional structure; both together aid in higher osteoconduction. The aim of present case report was to investigate if synthetic mineral collagen composite bone graft (CBG) with ribose cross-linked collagen membrane (RCLM) may be successfully used to obtain lateral augmentation of alveolar ridge that is planned for dental implant placement. Lateral augmentation of ridge was performed by elevating a full-thickness mucoperiosteal flap, followed by debridement and decortication of the defect area. CBG was soaked in saline and molded onto the defect area. RCLM was used to cover the graft site, followed by stabilization of membrane and the flap by suturing. Preoperative and postoperative ridge widths were measured using cone-beam computed tomography scans. The use of synthetic mineral collagen CBG with RCLM for lateral ridge augmentation may lead to increase in ridge width making it suitable for dental implant placement.
