No results posted yet for this study

Summary

evaluation of color difference between zirconia reinforced lithium silicate (celtra press) VS lithium disilicate (Emax) in relation to natural tooth structure to determine which monolithic material will provide restoration with exact shade and optical properties as natural tooth structure.

Conditions

  • Natural Optical Properties

Interventions

OTHER

Celtra Press

new class of zirconia-reinforced lithium silicate material available to labs for pressing. This unique material provides top aesthetics and is virtually impossible to tell apart from a natural tooth. Celtra Press is a multiphase ceramic consisting of a glass matrix and lithium disilicate crystals having a crystal length of about 1.5 µm plus nano-scale lithium phosphate . In addition to Li2O and SiO2, Celtra Press contains about 10% zirconia (ZrO2), which is dissolved completely in the glass phase rather than in crystalline form. Celtra Press is characterized by a high strength of about 500 MPa and excellent flow properties during pressing.
