Study Summary
A randomized, controlled clinical trial is designed to analyze the wear of enamel by opposing polished monolithic zirconia crowns and by the polished veneer surfaces of metal-ceramic crowns. This single-blind pilot study will involve a total of 30 teeth that require full coverage crowns that oppose natural antagonist teeth. The objectives of this research are to test the following hypotheses: (1) differences between mean wear of antagonist enamel by polished monolithic zirconia crowns and by the polished veneer surface of metal-ceramic crowns are statistically significant; (2) differences between mean wear of antagonist enamel by opposing polished monolithic zirconia crowns and enamel by opposing enamel are statistically significant; and (3) differences between mean antagonist wear of enamel by opposing polished veneer surfaces of metal-ceramic crowns and enamel by opposing enamel are statistically significant.
Primary Outcome
The wear of the enamel opposing the monolithic zirconia will be measured and compared with wear with the metal-ceramic crowns by using scanning technology to scan the teeth at baseline and then at the succeeding time periods. Also, impressions of the teeth will be used on a laser scanner to measure the volume loss on the crowns and the opposing teeth.
Interventions
