Interdisciplinary treatment of an end-to-end occlusion due to congenitally missing maxillary lateral incisors.

Odontogenic aplasia, or the congenital absence of permanent teeth, is relatively common. When the missing teeth include the maxillary lateral incisors, treatment considerations must reconcile both esthetic and functional objectives. In developing dentition, erupting adjacent teeth can drift from their intended positions into the edentulous space created by the congenitally missing tooth. When this movement happens (e.g., cuspids shifting more mesially than normal), esthetic and functional problems occur. A restorative solution for missing maxillary lateral incisors subsequent to the loss of the maxillary incisor spaces is presented while highlighting the use of a leucite-reinforced material. This approach allowed for a minimal preparation design and conservation of tooth structure, providing an optimal bond.
