CAD/CAM technology and esthetic dentistry: a case report.

Advances in dental materials as well as in computer technology have made CADCAM-fabricated restorations not just possible in dentistry but plentiful. When using CADCAM systems, operators can fabricate restorations from several materials, including ceramics, metal alloys, and various composites. This case report describes the replacement of a porcelain-layered zirconia-based (coping) crown on a left lower cuspid that presented with a veneering ceramic chipping on a lithium-disilicate CADCAM-fabricated crown. It demonstrates how all-ceramic systems offer a promising alternative in the restoration of anterior teeth.
