It is a general purpose impression material for making study models, first impressions for the construction of individual trays, situation models, orthodontic impressions etc.
Xantalgin Crono is a dental impression material based on alginate. Xantalgin Crono has the special characteristic of being a color-changing alginate: it becomes blue upon contact with water in the mixing bowl. It changes to violet indicating the end of the mixing time and loading the tray. Then it changes to pink indicating the moment to insert the tray into the mouth of the patient and finally it changes to white indicating the end of the setting time in the mouth.
