You can make 24 bridges from a single cartridge.
How much time do I have from the time the material is mixed until placement in the mouth?
When must LuxaCrown be removed from the mouth?
LuxaCrown is removed during the elastic phase, i.e. 1:45-2:20 minutes after mixing LuxaCrown. This value applies to intraoral application. Outside of the mouth, approximately double the time is required. Monitor the setting process with the probe and/or place a sample of the material on your hand and test for “gummy bear” consistency.
How do I prevent the opened cartridge from drying out?
To prevent an opened cartridge from frying out leave the used mixing tip on the cartridge as a cap.
Are there factors that can influence the setting response of LuxaCrown (e.g. latex, contamination in the blood…)?
There are no known factors that inhibit LuxaCrown’s setting response.
How do I avoid air bubbles in the LuxaCrown restoration?
Bubbles can be avoided by keeping the mixing tip immersed in the material preventing air from becoming trapped.
