ANSI/ADA Specification No. 53-1999

Crown and Bridge Plastics

This specification covers polymer-based crown and bridge materials for laboratory-fabricated permanent facings or anterior crowns which may or may not be attached to a metal substructure. This specification also applies to polymer-based crown and bridge materials for which the manufacturer claims adhesion to the metal sib-frame without macromechanical retention, such as beads or wires. This specification further classifies polymer-based crown and bridge materials and specifies the requirements; it also specifies the test methods to be used to determine compliance with these requirements. The specification is an adoption of ISO 10477:1992, and 10477 Amendment 1:1998.
