ABSTRACT:
Bond strengths of orthodontic appliances are enhanced by applying heat to heat softenable projections of a bonding base of the appliance, and then moving outer portions of the projections in lateral directions to present overhanging regions. The overhanging regions provide undercut areas that mechanically interlock with adhesive when the appliance is bonded to a tooth and the adhesive hardens. The method is useful for plastic appliances as well as other appliances that are made of materials exhibiting thermoplastic characteristics during at least one phase of their manufacture.
