ABSTRACT:
A method of making an optically clear custom tooth positioning and retaining appliance in a flask or mold device having mold members from an elastomeric or resilient thermoplastic material with the capability of having optically clear transparentness, after the appliance has been trimmed and/or buff polished subsequent to molding thereof which causes the appliance to have a frosty or translucent appearance, which method includes subjecting the exterior surfaces of the appliance to a source of concentrated heat to cause surface melting which produces transparentness, cooling the appliance before, during and after heating as needed to preserve its integrity, and optionally utilizing the mold members from the flask or reproductions thereof in the archways of the appliance during heating thereof.
