Computer-aided designed/computer-assisted manufactured composite resin versus ceramic single-tooth restorations: a 3-year clinical study.
Int J Prosthodont. 2010 May-Jun; 23(3):223-30.IJ

Abstract

PURPOSE

No clinical evidence has been provided to suggest that metal-free all-composite resin indirect restorations are a functional and esthetic alternative to all-ceramic restorations. The aim of this study was to evaluate the clinical performance of single-tooth computer-aided design/computer-assisted manufacturing (CAD/CAM)-generated all-composite resin and all-ceramic crowns after 3 years of function.

MATERIALS AND METHODS

In a prospective trial, 200 all-composite resin and all-ceramic crowns were rated over a 3-year period. Restorations were evaluated at 3 weeks and 1 and 3 years after insertion by the California Dental Association quality evaluation index, the patient's self-assessment, marginal fit, periodontal parameters, volume loss, and wear patterns of the veneering material. Statistical analysis was performed using t tests (a = .05).

RESULTS

Cumulative survival and success rates after 3 years were 87.9% and 55.6% for all-composite resin and 97.2% and 81.2% for all-ceramic crowns, respectively (P < .05 for success rates). Restoration loosening occurred exclusively for all-composite resin crowns cemented on a cast post. All-ceramic restorations demonstrated satisfactory esthetic results. All-composite resin crowns resulted in significantly more mean total volume loss and mean vertical wear at occlusal contact areas after 6 months and 3 years of function. The clinical performance of the CAD/CAM-generated all-ceramic crowns used in this study was similar to that of other all-ceramic CAD/CAM systems.

CONCLUSION

For up to 3 years of function, all-composite resin single-tooth restorations have inferior success rates compared to all-ceramic restorations. Due to the inferior esthetics and wear resistance of all-composite resin crowns, all-ceramic crowns remain the preferred treatment for CAD/CAM-generated metal-free single-tooth restorations.
