Exploring Ductility in Dental Ceramics [PDF]
Journal of Dental Research, 2022 Two damage regimes—“brittle” and “ductile”—have been identified in the literature on ceramic grinding, machining, grit blasting, and wear. In the brittle regime, the damage mechanism is essentially crack formation, while in the ductile region, it is quasiplasticity.

Polishing dental ceramics using shear-thickening slurry [PDF]
Scientific ReportsNowadays, there is a great demand for Zirconia dental ceramics, while the existing low-cost automated polishing methods are quite limited. We propose a novel polishing methodology employing the shear-thickening slurry (STF) comprising starch and SiC ...

Fatigue of dental ceramics [PDF]
Journal of Dentistry, 2013 Clinical data on survival rates reveal that all-ceramic dental prostheses are susceptible to fracture from repetitive occlusal loading. The objective of this review is to examine the underlying mechanisms of fatigue in current and future dental ceramics.The nature of various fatigue modes is elucidated using fracture test data on ceramic layer ...
