- Recommended for Keystone's and Asiga's resins.
- Complete post-curing — crucial for biocompatible materials.
- Consumable — replace at cracks or discolouration.
The tray decides which light reaches the restoration, and the 280N2 transmits the entire range from 280 to 950 nm. That is why it is the first choice for Keystone's and Asiga's resins. A cracked or discolored tray transmits less light, and on a biocompatible material that is not a cosmetic question: the post-curing is what binds the residual monomer. If it is incomplete, monomer is left in something that is to be worn in a patient's mouth, and the appliance is no longer the product the manufacturer has documented.
