Mechanical Properties And Failure Analysis Of Alumina-Glass Dental Composites

Strength measurements and fractography were used to investigate the failure of alunmina-glass dental composites containing 75 vol% alumina and 25 vol% glass. Crack deflection and crack bridging were observed in indentation cracks. Fracture toughness was single-valued because the alumina particle size was small. Alumina-glass composites are promising new ceramics for dental crown and bridge applications because their strength and fracture toughness are ~2times greater than those of current dental ceramics.
