Objective: Conical tooth anomalies can cause esthetic and orthodontic problems in individuals. This is a case of restoration for a peg-shaped lateral incisor with a direct composite resin veneer, which provides esthetic results by recovering the ideal tooth shape and size.

Methods: A 19-year-old male patient was referred from the Department of Orthodontics. After the radiographic and clinical examination, a unilateral conical shaped maxillary lateral incisor was detected (#12). The patient was under orthodontic treatment; therefore, a direct composite veneer was chosen among the treatment options as it is more favorable in adjusting and controlling the tooth shape and axis.

In the first appointment, a preliminary impression was taken for a diagnostic cast and a diagnostic wax-up was made on the cast over which a putty index of the anterior tooth was made. The wax-up of tooth #12 was made to have a similar shape and size of the opposite tooth (#22). The axis of the corresponding tooth was not ideal; thus, it was restored according to the orthodontically planned axis which was confirmed through simulation software after 3d scanning of the wax-up cast.

For the restoration of the tooth, body, dentin, and enamel shade nanocomposites (Filtek Z350 XT, 3M) in A2 shade and a universal adhesive system (All bond universal, Bisco) were used with layering technique. Finishing and polishing was done using polishing discs and diamond impregnated burs.

Results: At the 3-month follow up, the restoration was well maintained in accordance with the planned axial changes. No discomfort of the patient was found.

Conclusion: The direct techniques are minimally invasive, which can preserve the tooth structure. Also, the patient’s esthetic expectations can be satisfied with the direct composite restorations.
