Brief Summary:
When restoring teeth with IPS Empress laminate veneers, fracture of restorations may occur. So, material with higher mechanical properties is required. Celtra Duo is a new material with glass ceramics infiltrated by 10% zirconia particles which increase the fracture resistance of the material.
