  • Product Details

    Ultrapak cord is made of 100% cotton, knitted into thousands of tiny loops to form long, interlocking chains. This unique knitted design exerts a gentle, continuous outward force following placement, as the knitted loops seek to open. Optimal tissue displacement occurs in 1–3 minutes. Ultrapak E is impregnated with racemic epinephrine hydrochloride.​

    Ultrapak cord is used for rapid tissue displacement prior to impression-making and can also be used to deliver ferric sulfate solutions subgingivally for sulcular fluid control. Ultrapak is designed to enhance ViscoStat, Astringedent, and Dento-Infusor tissue management techniques. Conventional techniques using alum, aluminum chloride, etc. are also enhanced when using Ultrapak plain knitted cords, which carry significantly greater quantities of hemostatic solution than conventional cords.

    *Note: Do not use Ultrapak E or other epinephrine preparations with ferric sulfate solutions, including ViscoStat, Astringedent, and Astringedent X, as a blue/black precipitate will occur. Ultrapak with Epinephrine is not available in all countries. 1 2 “Can’t Live Without” Clinical Research Associates Newsletter, Volume 21, Issue 7, July, 1997.​ ​​

  • Testimonials

    • ​Nothing makes my day more than a crisp, clear crown impression on the first tray. Two-cord technique with Ultradent cord for the win!
      Dr. Anastasia Foufas
    • ​Ultrapak helps you get great impressions the first time! It is easy to pack, and when used with ViscoStat it is an unbelievable combination for a dry sulcus and a clear impression. So much detail even a patient could trim the die!
      Dr. Nick AbuJamra - Green Bay, WI
    • ​I love the cutter cap of the Ultrapak retraction cord!
      Dr. Sharon Feller - Concrete, WA
    • ​Ultrapak is excellent at displacing the gingival tissue, allowing proper hemostasis, and is easy to place and remove. It works very well for all retraction purposes. The different sizes are good for all situations.
      Dr. Y Clement Shek - San Francisco, CA
    • ​In dentistry, time is money. Ultrapak's woven design makes packing the cord quick and easy, plus the tooth can be prepped or touched up without snagging the cord. This increases patient comfort in shortening the appointment with far less repeat impressions.
      Dr. Thomas J. Frankfurth - Tampa, FL
    • ​Ultrapak cord has taken the stress out of cord packing. This was the most frustrating part of my day when I was using other products. Add the amazing Astringedent and...LIFE IS GOOD!
      Dr. Lisa Marshall - Xenia, OH
