Wear of Enamel Against Polished Zirconia Crowns

NCT02289781 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 30

Last updated 2024-10-01

No results posted yet for this 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.
