One Year Clinical Evaluation of IPS Empress CAD Versus Polished Celtra Duo Ceramic Laminate Veneers

Not Applicable

• Conditions: Tooth Discoloration; Tooth Fractures; Diastema
• Interventions: Other: polished Celtra Duo; Other: IPS Empress CAD

• Registration Number: NCT03136276
• Lead Sponsor: Cairo University

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.
