Morphologic anterior tooth alterations and diastemata between the anterior teeth are often considered a major esthetic problem. In most cases, the treatment of these conditions involves a multidisciplinary approach. Orthodontic treatment together with direct composite resin veneers are a viable option to close diastemata and alter tooth shape. The extent and etiology of the diastemata must be considered and properly evaluated for the treatment. The present article is a case report of a patient with multiple diastemata in the maxillary anterior teeth, dental crowding, and peg-shaped lateral incisors corrected with orthodontic treatment and direct composite resin veneers. Digital planning was the tool used to decide the tooth proportions before orthodontic treatment and to guide the diagnostic wax-up. An etch-and-rinse adhesive system was applied after etching. A polychromatic layering technique under rubber dam isolation was used for the composite resin veneer construction. Finishing and polishing procedures were achieved using polishing discs and abrasive materials. Direct composite resin is an alternative that allows predictability, esthetics, and the possibility of adjustments, resulting in patient satisfaction.
