About bonding adhesives
The FDA describes a bracket adhesive resin and tooth conditioner as an adhesive compound intended to cement an orthodontic bracket to a tooth surface, a Class II device (21 CFR 872.3750). The etching acid demineralises enamel at varying rates, creating microporosities and an uneven surface that allows strong micromechanical adhesion. The design of the bracket base also affects the bond strength; bases include beaded, large-round-pitted, irregular and metal mesh.
The resin that holds a bracket on the tooth, used after the enamel has been conditioned. Bonding a bracket to a ceramic surface fails more often than bonding to enamel, and calls for a different etching protocol because ceramics resist acid.
