Summary

The purpose of this study was to evaluate the clinical performance of laboratory and chairside fabricated monolithic anterior and posterior LDGC CAD/CAM crowns performed by predoctoral students at the University of Toronto and the effect of different patient and provider-related factors on their longevity and to compare them to the metal-ceramic (MC) crowns. A sample of LDGC CAD/CAM crowns (IPS e.max, Ivoclar Vivadent) provided by predoctoral students was evaluated. Crown preparations were made according to the specific criteria and were milled in-house using the CEREC bluecam and Omnicam systems. Crowns were cemented with Rely-X Unicem (3M/ESPE) and Calibra Universal (Dentsply Sirona) resin cements. Clinical assessment of the crowns and supporting periodontal structures was performed following the modified California Dental Association (CDA) criteria. Intra-oral photographs, periapical and bitewing radiographs were taken for further assessment by two evaluators. Two-hundred and fifty-one patients with 275 crowns were examined with a follow-up period of up to 6 years.
