Cairo University (CU)

Status: Unknown

Conditions: Tooth Discoloration; Diastema; Tooth Fractures

Treatments: Other: polished Celtra Duo; Other: IPS Empress CAD

Study type: Interventional

Funder types: Other

Identifiers

Details and patient eligibility

About

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.
