[Use of the CEREC system in dental practices. Esthetic reconstruction of the anterior teeth--a case report].

The replacement of a metal-ceramic crown utilizing CAD/CAM technology is described in this case report. A healthy, 42-year-old patient complained about aesthetic appearances after the reconstruction of tooth 11 with a metal-ceramic crown. Depending on the production process CEREC crowns are divided in direct and indirect CEREC reconstructions. In this case the indirect way was elected, where the CEREC crown is customized by the technicians. After the final tooth preparation and the immediate dentin sealing the impression and bite registration was taken conventionally. Then the crown was manufactured with the CEREC 3-D-system and the technicians reduced the labial aspect of the CEREC crown and completed the reconstruction by veneering. Success ist closely linked with the quality of the laboratory work and the precision employed by the dentist regarding the preparation and integration technique. The replacement of a metal-ceramic crown on a vital tooth utilizing the CEREC 3-D-technology can lead to aesthetically pleasing, functional outcomes with great patient and clinician satisfaction.
