Implant-supported overdentures.

Retention of the lower complete denture is always a question for the dentist and the patient because of the alveolar ridge resorption and many muscle attachments to the mandible. The treatment of edentulous patients using oral implants does not always permit the placement of an adequate number of implants for fixed prosthesis construction; the reasons are insufficient anatomical bone height of the alveolar ridge, health restrictions and financial limitations. Placement of two dental implants in the cuspid regions anterior to the mental foramina on either side will improve the retention and stability of complete dentures in edentulous patients.

Hyperdontia in children--case reports.

Dental anomalies are craniofacial abnormalities of form, function or position of the teeth, bones and tissues of the jaw and mouth. Dental anomalies can range from missing or stained teeth to cleft palates. The National Institute of Dental and Craniofacial Research (NIDCR) estimates that in the United States a baby is born every hour with a craniofacial defect.
