Flexural strength and reliability of monolithic and trilayer ceramic structures obtained by the CAD-on technique

Highlights • This study evaluates the flexural strength, Weibull modulus, and fracture mode of ceramic structures obtained by the CAD-on technique. • This study tested the hypothesis that trilayer and monolithic structures show similar values for the evaluated properties. • Monolithic and trilayer s...

More Information
Summary:Highlights • This study evaluates the flexural strength, Weibull modulus, and fracture mode of ceramic structures obtained by the CAD-on technique. • This study tested the hypothesis that trilayer and monolithic structures show similar values for the evaluated properties. • Monolithic and trilayer specimens showed similar mean flexural strengths, characteristic strengths and Weibull moduli. • Considering the CAD-on technique, the trilayer structures showed greater fracture toughness than the monolithic zirconia specimens.
