Scannable, addition-curing bite registration material based on vinyl polysiloxane which is extremely hard and has a very short setting time. Regidur scan is characterised by optimal scan results. It can be used for all optical and laser systems and is compatible with all common CAD/CAMsystems. The annoying use of powder is not necessary. The setting time of Regidur scan is adapted to the needs of optimal use in dental practices and laboratories. In spite of the high final hardness of 32 shore D, Regidur scan can easily be finished with a stone or milling cutter without breaking. The application is time-saving as the material is applied directly from the cartridge. Thanks to its thixotropic properties, Regidur scan is extremely stable. It can also be used for standard bite registrations.
