The Success Injection System incorporates a closed flask system injecting denture base materials under continuous pressure, eliminating the need for trial packing and reducing the chance for change in vertical dimension of occlusion. The Success system combines the precision of injection with the performance of Lucitone denture base materials to enable technicians to create a wide variety of denture appliances with consistency and accuracy. Doug Brydels discusses the basics of injecting Lucitone 199® (heat cure and microwave), Luci-Sof® Injectable, Lucitone® FRS® and Thermoflex™, and demonstrates an FRS® injection.
