ULTRAFLEX Thermal Composite Hybrid Resin A partial denture material with flex, that unlike conventional nylon materials can be easily repaired or relined. ULTRAFLEX™ partials with clear clasps offer optical clarity that blend naturally against existing teeth. It is allergy free (MMA, BPA, and silicone-free), requires no special equipment or injectors to process, and can be press-packed or poured and cured in a pressure pot. Can be used in place of or in conjunction with metal partials. Lab kit includes: 160g Powder / 80g Liquid
