Abstract

Patients with cleft lip and palate have several problems such as oro-nasal communication, dental cross-bite caused by the insufficient growth of maxilla, poor pronunciation and esthetic problem. Removable denture with maxillary double crown near cleft palate and with clasp in the posterior teeth was used to solve the problems of the patient with cleft lip and plate. Double crowns make up for the insufficient mucosal support caused by the mucosa and alveolar bone loss in cleft lip and palate. Double crowns also allow easy repair of denture in case of abutment teeth extraction. In this case, 55-year-old female patient had bilateral cleft lip and palate and few remaining teeth on anterior maxilla. Prosthetic treatment was done for patient with bilateral cleft lip and palate to close oro-nasal communication using maxillary double crown and clasp retained removable denture. As a result, oro-nasal communication was effectively closed and the cross-bite was easily corrected by double crown and clasp retained denture. In addition, pronunciation and appearance were also improved.
