Brief Summary

The aim of the present study is to evaluate the wear of enamel opposed by Newly Introduced Gradient Monolithic Zirconia compared to that of enamel opposed by Full Strength Monolithic Zirconia

Conditions

Wear, Occlusal

Outcome Measures

Primary Outcomes (1)

• Enamel wear of teeth opposing the restorations to be tested opposing to tested restorations

  measured by Geomagic professional software

  one year

Secondary Outcomes (1)

• Wear of restorations to tested opposed to natural teeth

  one year
