Avoid try-in troubles. You may not realize that during intraoral try-in, the interior surface of the restoration can be contaminated. If these surfaces are not properly cleaned there can be problems with adhesive cementation. While glass ceramics can be cleaned with a phosphoric acid gel, zirconia and alloy restorations require a different cleaning protocol. A simple solution to this is Ivoclar Vivadent’s Ivoclean™, a universal cleaning paste that can be used on restorations fabricated from glass ceramics, zirconia, alumina, precious and non-precious alloys and composites. Ivoclean is simply applied to the bonding surface for 20 seconds and then rinsed away. The surface is dried with air before seating.
