Interface is a revolutionary ceramic primer, which allows the clinician to bond any type of ceramic to a tooth, including the newer high-strength materials. With Interface, any ceramic restoration can be delivered or repaired (in vivo). Since it is activated when it is used, the shelf life of the primer is extremely stable (3 years from the date of manufacture). Perhaps best of all, Interface can be used to prepare ceramic, dentin and enamel ALL AT THE SAME TIME. 2x 3ml bottles.
