Objective: Peg shaped maxillary lateral incisors can cause esthetic challenges, such as diastema between teeth. This case reports a peg-shaped lateral incisor restored with direct composite resin veneer. The aim of the treatment is to close the diastema and restore the tooth shape and size to its normal contour to provide esthetic results.
Methods: A 13-year-old female patient undergoing orthodontic treatment was referred from the Department of Orthodontic Dentistry for restoration of peg-lateral maxillary lateral incisors. Considering the patient's age, a direct resin veneer restoration was chosen among the treatment options for a more conservative approach. As the patient was undergoing orthodontic treatment, it was necessary to restore the ideal tooth shape. Therefore, space was left after restoration. Also, the two maxillary lateral incisors to be restored had different axial conditions; restorations were performed according to the axes for subsequent orthodontic treatment.
During the first visit, an impression of the anterior maxillary arch was taken for a diagnostic cast. Size and length of the tooth to be restored were measured and a wax-up of the ideal tooth shape was done. A silicone mold was made over the wax-up cast to be used as a guide to make the lingual surface. The restoration was performed with a universal adhesive system(All-Bond Universal, Bisco) and a resin composite (Filtek Z350 XT, shades A2 and A3; 3M) followed by polishing (SofLex disks, 3M).
Results: At the 3-months follow-up, shape, form, color and the maintenance of the direct composite resin veneers were acceptable, and patient showed no signs of discomfort.
Conclusion: Direct composite resin veneers are an esthetically and functionally appropriate treatment method in restoring peg-laterals, especially in growing patients.
