Wear of enamel antagonist to gradient zirconia vs full strength monolithic zirconia: a randomized clinical trial

Key Points

• Enamel wear is significantly less with gradient zirconia than with monolithic zirconia, indicating better performance.
• The study reveals that over a certain period, gradient zirconia causes lower enamel wear—highlighting its benefits.
• Assessment through a randomized clinical trial across multiple dental units reveals useful comparisons for dental practitioners.
• The findings support the use of gradient zirconia in restorative dentistry, but further research is warranted for definitive guidelines.
