Separator rings with improved performance and ease of use. The 2 main separator rings can be used for the majority of restorations, while the wide prep ring can restore extremely wide preps and missing cusps with excellent contact and contour. Ultra-Grip retention extensions anchor rings securely to virtually any tooth. Tru-Stack technology allows placement of the orange ring (tall) over the blue ring (short) for easier MOD and multiple tooth restorations. Soft-Face silicone tips with enhanced marginal ridge anatomy hug the matrix band to the tooth for flash-free restorations. Enhanced durability for extended ring life and greater tooth separation.
