Objective: The direct resin veneer is a conservative method to correct existing abnormalities, esthetic deficiencies, or discolorations. It is relatively inexpensive, can be completed within a single visit, and can be repaired, making them a good alternative to porcelain veneers.
This case report presents improvement of anterior teeth, leading to a “perfect” smile.
Methods: A 31-year-old male patient, who had completed orthodontic treatment, wanted to have a fractured part of the maxillary left lateral incisor treated; also, slight chipping of the #12, 21, 22 was found. In addition, discoloration was observed in #21 that had received a root canal treatment. The size of the anterior teeth was small and space between the maxilla and mandible existed. For accurate analysis and wax-up, a study model was created and shade taking was performed at the first examination. Firstly, the old core of #21 was removed, and non-vital bleaching was performed for 2 weeks to remove discoloration, and a resin restoration was performed 1 week later. For a harmonious gingival zenith, gingivectomy was performed, and composite resin restorations (Estelite Sigma Quick, Tokuyama) were placed using total etching with a universal adhesive (One-step plus, BISCO). During the restoration, the silicon index was used to reproduce the shape achieved by a wax-up. The remaining excess was removed, and the shape was modified through recall check.
Results: The patient maintained a satisfactory esthetic anterior region after approximately 6 months and the previous discoloration was completely masked. It is different from the average width/height value of 75-80%, but has a value less than 1, and the overbite is close to the normal value, so it is more balanced than before.
Conclusion: For successful anterior resin restorations, a wax-up using a diagnostic model can be performed, and both dental and gingival esthetics act together to provide better harmony and balance. Direct composite resins can be used in anterior restorations for better esthetic.
