Bosworth’s Sapphire is an acrylic peripheral impression material and bite registration material that can be used on custom or plastic impression trays for full denture impressions and border molding (muscle trim). Sapphire extends to the proper height without slumping. This soft material records peripheral detail without distortion and sets to become a rigid part of the tray. Sapphire’s no-burn, no-sting formula ensures patient acceptance. Available in blue or clear powder.
