Localized ridge augmentation using guided bone regeneration. II. Surgical procedure in the mandible.

The principle of guided bone regeneration can be applied for localized ridge augmentation in a staged approach. The surgical procedure for the mandible is presented through three case reports. Incision technique and flap design, utilization of autogenous bone grafts as a membrane-supporting device and osteoconductive scaffold, proper placement of barrier membranes and their stabilization with miniscrews, and wound closure are all emphasized. Furthermore, factors essential for achieving predictable results with barrier membranes for localized ridge augmentation and the benefits of combining barrier membranes with autogenous bone grafts are discussed.
