Dental abnormalities and abnormal facial appearance are of major concern in childhood and adolescence, since they can restrict the individual socially and affect his or her self-confidence. Oral rehabilitation in the early stages of the patient's life may provide functional and esthetic restoration as well as safeguard psychologic health. This report presents the clinical procedures involved in the rehabilitation of a 10-year-old female patient with complete bilateral cleft lip and palate and ectodermal dysplasia.
