Esthetic Rehabilitation of Elongated and Discolored Maxillary Central Incisors Using Mock-Up–Guided Restoration: A Case Study

Elongation and discoloration of maxillary central incisors can compromise smile esthetics and patient confidence. This case study presents the esthetic rehabilitation of elongated and discolored maxillary central incisors using a mock-upguided restorative approach with zirconia crowns. A diagnostic wax-up and intraoral mock-up were performed to assess tooth proportions, incisal length, and overall smile harmony prior to definitive treatment. The mock-up served as a guide for conservative tooth preparation and enhanced patient communication. Monolithic zirconia crowns were fabricated and cemented to restore optimal form, color, and function. Post-treatment evaluation demonstrated significant improvement in esthetics, proper occlusion, and patient satisfaction. Mock-up–guided zirconia restorations provide a predictable, durable, and esthetically pleasing solution for anterior dental rehabilitation.
