Ceramo-Metal Crown or Cad-Cam Rehabilitation: Patient and Practitioner Appraisal

Crowns produced using CAD-CAM technology must be evaluated so they can be integrated in the dentist's therapeutic arsenal. To this end, an evaluation tool for the fixed element units was developed and tested in a randomized cross-over pilot study. At a hospital centre, 10 single crowns from the same dental preparation and produced using CEREC technology were compared to Ceramo-Metal Crowns produced using a conventional procedure. Practitioners generally evaluated CEREC crowns more positively, corroborating the subjects' preference for these crowns. The CEREC technology used in a hospital setting meets the requirements of both patients and practitioners.
