Summary

In-vitro studies do not represent the actual masticatory environment and cannot simulate the intricate chewing pattern. Hence, there is a need for an in vivo study evaluating the wear potential of the newly introduced strength - color gradient multilayered zirconia IPS e.max ZirCAD Prime (5Y-TZP/3Y-TZP) and compare it to Lithium Disilicate IPS e.max CAD which has proven to have favorable wear patterns.

Detailed description

* There will be no difference in wear caused by monolithic Zirconia (5Y-TZP/3Y-TZP) IPS E-max ZirCad Prime and Lithium Disilicate IPS e.max CAD to the antagonist. * There will be no difference in the wear of the new monolithic zirconia IPS e.max ZirCAD Prime and lithium disilicate IPS e.max CAD.

Conditions

• Posterior Teeth
• Worn Posterior Teeth
• Endodontically Treated Teeth
• Crowned Posterior Teeth
