Impacted incisors associated with supernumerary teeth treated with a modified Haas appliance.

Abstract

Tooth impaction involves factors such as lack of space in the alveolar process, trauma, ankylosis, and mechanical barriers such as abnormal frenum, supernumerary teeth, tumors, and local cysts. When impaction occurs in the anterior region, esthetics are compromised. This report describes the successful approach to treatment for a young boy who had 2 supernumerary teeth associated with impaction of the left central and lateral permanent incisors. Treatment consisted of extracting the supernumerary teeth and performing maxillary expansion with a modified Haas appliance to guide the left central incisor into its appropriate position. The teeth erupted spontaneously after maxillary expansion and an increase in space. A fixed edgewise appliance was placed incrementally to correct the maxillary anterior tooth positions and finish the treatment. Adequate esthetics and function were achieved.
