The opaque buildup in A1 also offers various anatomical forms. Fortunately, these materials have been the focus of a great deal of research in recent years with the goal of improving restoration performance by changing the initiation system, monomers, and fi llers and their coupling agents, and by developing novel polymerization strategies. With a simplified, logical category description the clinician is better able to understand what each bonding agent is and how it is used. There can be confusion as to what bonding agents are being described, because there are a number of different labeling categories. 1995;26(2):95-110. the bonding agent and the composite resin material adhere to each other.
