Expansion Stone

X-Roc was developed for pouring the duplicate model in processing thermoplastic appliances such as: Flexite®, Valplast®, Flex-Star V, TCS®, FRS®, DuraFlex®, & DurAcetal®. This stone compensates for the shrinkage of these materials, thereby eliminating tight fits on removable prosthetics processed with conventional stones.

• Eliminates tight fits
