Abstract

ISO 20795-1 classifies denture base polymers, including materials for additive and subtractive manufacturing, and specifies their requirements. It also specifies the test methods to be used in determining compliance with these requirements. It further specifies requirements with respect to packaging and mmarking the products and to the instructions to be supplied for use of these materials. Furthermore, it applies to denture base polymers for which the manufacturer claims that the material has improved impact resistance. It also specifies the respective requirement and the test method to be used. Since the first editions of this standard, many developments have been made concerning materials used for mthe denture bases as well as for the technical processing of these materials. This revision of the standard was mstarted with the aim to include, in more clarity, some new materials and processing techniques, in particular mCAD-CAM using additive manufacturing (e.g. vat photopolymerization) and subtractive manufacturing (automated milling).
