Root-supported overdenture in a patient with a cleft palate and extensive bone loss after traumatic injury.

Maxillofacial trauma caused by automobile accidents can result in extensive loss of alveolar bone, teeth, and gingival tissues as well as a cleft palate. Patients who have undergone such trauma may experience a loss of vertical dimension of occlusion, esthetic deformity, and difficulties in speaking, chewing, and swallowing. Both prosthodontic and surgical treatment are required in these cases.
