Hypodontia: etiology, clinical features, and management.

Patients who are congenitally missing one tooth or more are frequently encountered in routine practice. The etiology, classification, and clinical features of hypodontia are reviewed, and treatment modalities are discussed. One case of mild-to-moderate hypodontia and one case of severe hypodontia are described. Osseointegrated implants have provided encouraging results, especially in patients who are missing anterior teeth or who have severe hypodontia.
