Long-term provisional restorations can be used to test a new restorative design and to improve the predictability of the definitive restoration with regard to shape, shade, occlusion, and soft tissue interface. To improve the clinical outcome and reduce costs, a new treatment strategy was developed. Teeth were restored with long-term provisional crowns fabricated from a polymer material using a computer-aided design/computer-assisted manufacture (CAD/ CAM) system. Definitive all-ceramic restorations fabricated by the same CAD/ CAM system were cemented as duplicates of the individualized provisional crowns after 3 months.
