ABSTRACT:
A method of enhancing the bondability of ceramic orthodontic brackets or other dental attachments for improving the bonding strength between such attachments and the tooth engaging surface utilizing an intermediate bonding agent such as an acrylic resin. The method of the present invention results in the application of a silicious glass-like material coating of the bonding surface of the dental appliance. The silicious glass-like material provides three functions: (1) the proper surface chemistry for the use of organofunctional silanes that act as adhesion promoters or primers to enhance the bond between the adhesive and the orthodontic bracket; (2) a medium whereby second phase particulates can be adhered to the bracket to form irregular surface projections to enhance bonding; and (3) a surface that can be etched to yield macro and micro pitting to enhance the bond between the appliance and the intermediate bonding agent.
