ABSTRACT:
Multi-piece, reusable orthodontic appliances that include a support assembly to be bonded to a tooth and a corrective assembly adapted to receive an archwire and direct corrective forces exerted by the archwire to the tooth. The support assembly is releasably engaged with the corrective assembly, such as with coupling portions that disengage responsive to a force applied to the corrective assembly exceeding a predetermined value, such as less than a force sufficient to debond the support assembly from the tooth. In response to such a force, the corrective assembly disengages from the support assembly, rather than the appliance debonding from the tooth. Self-release assemblies for use with a corrective orthodontic bracket, including either a support assembly or a corrective assembly, and an engagement assembly configured to disengage as described above, may allow a conventional set of orthodontic hardware to be retrofitted with a self-release feature.
