Biomaterials and Clinical Use Although the compressive strength of dental porcelain is high (350–550 MPa), its tensile strength is very low (20–60 MPa). The material, being primarily a glass, and thus very esthetic, lacks any fracture toughness. The maximum strain that a glass can withstand is <0.1%.

Why are dental ceramics brittle?
