SUPER-SOFT is a resilient, permanent heat-processed liner that is suitable for old or new, upper or lower dentures. This product contains zinc undecylenate, an antiseptic, astringent and fungicidal agent that slows down the potential fungal growth and prevents odor. It is extremely easy to use and process; no special equipment or technique is necessary. The heat cures to any denture resin, which provides permanent adhesion to denture resins that are suitable for old or new dentures. The controlled degree of softness, which is applied by adjusting the powder/liquid ratio, offers a range of softness to accommodate your patients.
