Size or hierarchical dependence of the elastic modulus of three ceramic-composite CAD/CAM materials.

Objective: To measure the elastic modulus of three ceramic-composite CAD/CAM materials at three different microstructural dimensions: macro, micro, and nano.

Methods: Three novel ceramic-composite CAD/CAM materials (Enamic, Lava Ultimate, and Cerasmart) were investigated. Rectangular cross-sections 10 × 5.
