Effects of nitrogen-assisted post-curing and layer thickness on the properties of a 3D-printed ceramic-reinforced composite resin for permanent crowns under different aging conditions: an in vitro study.

BMC oral health · Er A, Caglar I · 2026-07-29

Researchers compared how layer thickness and nitrogen-assisted post-curing affected water absorption, surface roughness, and strength of a 3D-printed ceramic-reinforced composite resin for crowns, with and without thermal aging. Post-curing at 4000 flashes produced optimal surface roughness and strength, while 2000 flashes resulted in inferior properties.
