Hydroxylapatite reconstruction of alveolar ridge deficiency with an open mucosal flap technique

A preliminary report on an open surgical technique for mandibular augmentation with hydroxylapatite has been presented. Twelve patients were evaluated from 2 to 20 months postoperatively. Advantages are thought to include better ridge form, maintenance of vestibular depth, and visualization of the mental nerve. In addition, splints usually are not necessary. Disadvantages include increased surgical time, possible lower lip inversion, and soft-tissue characteristics that may require secondary revisions.
