Webtest to be performed prior to tensile testing (Ref. 1). Metal-to-ceramic brazing can be accomplished by first applying a metallic layer onto the ceramic surface or by braz-ing directly to the unmodified ceramic (oxide) surface. Several metallization methods have been proven to work effec- ... Tensile strength averages are ± 2 ksi/14 MPa ... WebFlexural, compressive and tensile strength as well as the modulus of elasticity of 15 different dental ceramics were evaluated. Conventional dental ceramics differed insignificantly in their mechanical properties. By testing new products like Cerec 2 and especially In-Ceram there was found an evident increase in inner strength.
