Combined Orthodontic and Restorative Approach to Esthetic Treatment of Maxillary Peg Lateral Incisor in Adolescent Female Patient: Case Report.

The presence of a peg lateral incisor is an example of an autosomal dominant genetic condition that is often associated with several other dental abnormalities, including tooth agenesis. It can occur either unilaterally or bilaterally. Individuals with peg lateral incisors often present with an associated midline diastema, as well as other anterior diastemas. The esthetic restoration of a peg lateral incisor can become a transformative event for an adolescent female patient. This article describes a combined orthodontic and restorative approach to the management of this condition, using a direct composite veneer without tooth reduction. This most conservative and minimally invasive treatment is especially appropriate in the adolescent patient. Final esthetic results are optimized by this combined interdisciplinary approach. By planning for the resultant space mesial and distal to the peg lateral incisor, composite resin can be veneered directly over the tooth to provide excellent esthetics. Other treatment options can be considered in adulthood, if necessary.
