Esthetic Management of Maxillary Midline Diastema Using Porcelain Laminate Veneers: A Case Report

Maxillary midline diastema (MMD) is a common esthetic concern that can affect smile harmony and patient self-esteem, especially in cases involving intrinsic enamel defects like dental fluorosis. Managing diastema in fluorosed teeth presents clinical challenges due to enamel alteration and reduced bonding efficacy. This case report describes the esthetic rehabilitation of a 28-year-old male patient with a 4 mm diastema and moderate fluorosis-related discoloration of the maxillary anterior teeth. The patient had previously undergone unsuccessful orthodontic treatment. A minimally invasive treatment plan was developed involving porcelain laminate veneers (PLVs) placed on the four maxillary incisors. Diagnostic wax-up, mock-up, and digital impressions were used to guide the enamel-preserving tooth preparation. These steps also facilitated the precise fabrication of the veneers. The restorations were bonded using an adhesive protocol adapted to fluorosed enamel. The treatment resulted in successful diastema closure, harmonious tooth proportions, shade improvement, and high patient satisfaction. This case illustrates the value of PLVs as a conservative, effective, and esthetically reliable solution for midline diastema closure in a patient with moderate dental fluorosis and a history of failed orthodontic treatment, highlighting the importance of restorative alternatives when conventional approaches are unsuccessful.
