Effect of nitrogen-assisted and ambient-air post-curing protocols on surface hardness and degree of conversion of a 3D-printed occlusal splint material

Post-curing is a critical step in the fabrication of 3D-printed resin-based occlusal splints because it influences polymerization efficiency and final material properties. Atmospheric oxygen may inhibit free-radical polymerization at the resin surface, whereas nitrogen-assisted p...
