Used to check the fit of dental restorations, dental articulation materials can be a spray, a paste, a gel or another format. These materials are applied to the surface of restorations to check that they properly fit or if adjustments need to be made. Different materials can be used to check the fit and proper articulation of fixed restorations such as crowns and bridges and removable restorations such as dentures. These materials should be able to clean up completely so they do not leave a residue on the restoration.
