The wax disc is a specialized sculpting wax material for dental prosthetics, composed of a composite of beeswax/paraffin wax/synthetic wax. With a softening point range of 38-42°C, it is used for crafting crown/bridge wax patterns, bite registrations, and orthodontic models. Its sculptural precision (±0.1mm tolerance) and thermal expansion coefficient (0.35%) strictly meet metal casting requirements, while exhibiting unique stratified color-display characteristics during clinical handling to distinguish functional zones.
