SHELL

 

Nacera® Shell are reliable materials for most available CAD/CAM systems.

Our certified manufacturing process ensures the production of uniform blanks with regard to both the material properties and the coloring. The components are available in white and two other color shades. Multiple indication: suitable for everything from veneers to wide-span implant-supported bridges (up to 14 units) Homogeneously shaded blanks ensure high realibility of colors and processes Pearl 1: highly translucent and superior stability: 1500 MPa, HV 1300 Natural translucency increases the aesthetics of monolithic restorations Flexible sintering temperature: 1450 °C – 1550 °C Perfect Fit thanks I.F.P. - Instant Fit Process

Flexural Strength

4-point bending strength (MPa) DIN EN ISO 6872. The higher the fl exural strength of zirconia (ZrO2) the better the stability under masticatory loading.
