Description
Khaled Bataineh and Mohammad Al Janaideh simulate how long thin ceramic crowns survive chewing fatigue, in a study published in 2023. Computer-designed crowns can be made slimmer than ever, but thin ceramic risks cracking over years of bites. The team compared zirconia and lithium disilicate at three thicknesses.
Finite element simulations loaded the crowns at forces from gentle to strong. For zirconia, the thin and thick designs lived about equally long. Even the ultra-thin version, under a moderate load, was predicted to last decades, though hard loads cut that to a few years. The glass-ceramic rival fared worse: only the thickest design survived five years under a strong load. The authors conclude ultra-thin zirconia crowns have adequate endurance for normal mouths. Lithium disilicate, they advise, should stay at full thickness for longevity.
