Ultradent Ultrapak Retraction Cord
Ultrapak is made of 100% cotton, woven into thousands of tiny loops to form long intertwined chains. This unique woven design exerts a soft, continuous force outwardly after placement, as woven loops seek to expand. Optimal tissue displacement occurs in 1-3 minutes. Ultrapak E is impregnated with racemic epinephrine hydrochloride.
The Ultrapak thread is used for rapid tissue displacement prior to printing intakes and can also be used to deliver ferric sulfate solutions to the subgingival sector to control the sulcular fluid. Ultrapak is designed to improve tissue handling techniques with ViscoStat, Astringedent, and Dento-Infusor. Conventional techniques using alumina, aluminum chloride, etc., also improve when unpardened Ultrapak woven yarns are used because they carry significantly larger amounts of haemostatic solution than conventional yarns.
