You can't truly understand how to use a material, until you see it in many different ways. ZRo2 is no different! I understand it better than most, and I love showing others the possibilities of this #1 dental material. Infiltration is just one way you can improve your canvas. Does not matter whether your a monolithic or layered technician. Improve the canvas and improve everything you do. This is just a sample of the posibilities of raw bleach ZRo2, and how you can internally modify it. All materials are Ivocalr... of course.
