Amelogenesis imperfecta is a hereditary disease affecting the structural development of tooth substance. This clinical report describes a 1-visit chairside treatment of an 8-year-old patient with amelogenesis imperfecta, using computer-aided design and computer-aided manufacturing (CAD-CAM) technology. Intraoral scanning was performed using the Cerec Omnicam. Thirteen resin nanoceramic crowns (Lava Ultimate) were fabricated chairside by using a Cerec MCXL milling unit and seated adhesively. The patient's treatment included establishing a new occlusal vertical dimension and new centric relationship. Reevaluation after 6 months showed a stable situation.
