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 3–8 minutes. Ultrapak E is impregnated with racemic epinephrine hydrochloride.​

  • The original—and smallest—knitted cord
  • Provides rapid tissue displacement, detailed margins, and quality impressions
  • Facilitates easy packing and stays placed better than any twisted or braided cord
  • Compresses upon packing then expands for optimal retraction
  • Does not entangle in diamond bur
  • Bright colors facilitate easy location and removal
  • Available with or without epinephrine*​
  • High carbon steel blade ensures a clean cut
  • Thin plastic gate prevents cord from falling into the bottle upon cutting
  • Ruler printed on label provides easy cord measurement​

*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.

Indications for Use

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.


Rapid Tissue Displacement

Ultrapak compresses upon packing then expands for optimal tissue displacement.
Ultrapak, saturated with ViscoStat, controls bleeding and sulcular fluid for near gingival and subgingival preparations.

Ultrapak CleanCut

The Ultrapak CleanCut design features a blade in the cap for the ultimate convenience.

  • High carbon steel blade stays sharp!
  • Thin plastic gate prevents cord from falling into the bottle upon cutting
  • Ruler printed on label provides easy cord measurement
  • Safety feature built into cap avoids risk of injury

The One with the Stripe!®

With easy packing, excellent absorption, and exceptional retention, Ultrapak’s proprietary knitted design has been the preferred choice for years.



Technical Details

The World’s Smallest Knitted Cord

Knitting a cord small enough to fit into the sulcus was no easy task. In fact, it took 9 months to knit the first 1 inch of the size #0 cord. Once we had learned the best methods and techniques to knit Ultrapak’s microscopic loops, we learned we could make even smaller cords—all the way to size #000, the smallest knitted retraction cord in the world.

Knitted, Not Braided or Twisted

Prior to Ultrapak, all retraction cords were either twisted or braided. When the clinician tries to pack a twisted cord with a packing instrument, the instrument slips between the fibers of the cord. Braided cord elimintated that problem, but a braided cord is very rigid, which makes packing into the sulcus challenging. Knitted cords are flexible and allow for easy packing with an instrument. The microscopic compressible loops of the knitted cord afford greater interthread space than braided cord. Upon packing, the loops compress and express hemostatic astringent to underlying tissues. As loops open, a gentle, continuous outward force is exerted. A knitted cord is like a chain; it bends and stays put when packed into place.

6 Sizes

Ultrapak comes in cords as small as size #000 to as large as size #3, making Ultrapak suitable for any clinical situation. The smaller cords are ideal for pediatric cases where carious lesions have extended beyond the gumline  and as the first cord in the double-cord technique. The larger cords work well as the upper cord in the double-cord technique and for areas that have thick gingival tissues that require a significant amount of force to be retracted.



  • Use as lower cord in the double-cord technique
  • Anterior teeth
  • Double packing


  • Preparing and cementing veneers
  • Restorative procedures dealing with thin, friable tissues


  • Lower anteriors
  • When luting near gingival and subgingival veneers
  • Class III, IV, and V restorations
  • Second cord for double-cord technique


  • Non-impregnated #1 and #2 sizes are particularly effective for tissue control and/or displacement when soaked in coagulative hemostatic solution prior to and/or after crown preparations
  • Use as a protective pre-preparation cord on anteriors


  • Upper cord for double-cord technique
  • Use as a protective pre-preparation cord


  • Areas that have fairly thick gingival tissues where a significant amount of force is required
  • Upper cord for use with the double-cord technique


Pre-Preparation Packing Technique

  1. PREPACK. To ensure cord retention during preparation, use a cord large enough to firmly compress into sulcus. Open proximal contacts and place Ultrapak knitted cord soaked in hemostatic solution. Because Ultrapak compresses upon packing, use a cord size that appears too large. The thin Ultrapak Packer quickly slips cord into position. The knitted cord’s unique design (interlocking loops) facilitates easy packing and locks it into place.

  2. PREPARATION. Extend margin subgingivally by cutting partway into knitted cord, which won’t entangle in the diamond bur. Remove remnant of cord with calcium hydroxide applicator (tiny ball end). Bleeding is minimal. A small portion of uncut tooth above the gingival attachment is preserved to record in the impression.

  3. HEMOSTASIS AND IMPRESSION. Rub the Dento-Infusor tip against bleeding tissue as solution is slowly expressed. Rinse with a firm air/water spray to clean and check for complete hemostasis. If bleeding is noted, repeat these steps. If additional retraction is required, repack with appropriate-size cord. Air dry and make impression.
