Ultrapak Knitted Gingival Retraction Cord – Achieve Precision in Every Impression. Ultrapak is a high-performance, 100% cotton gingival retraction cord designed to rapidly and effectively displace tissue before taking dental impressions. Unlike conventional twisted or braided cords, Ultrapak's knitted design compresses during placement and then expands gently to exert continuous outward pressure, creating optimal tissue separation with minimal trauma. This innovative knitted structure absorbs and carries significantly more hemostatic solution than traditional cords, making it an ideal companion for ViscoStat, Astringedent, and Dento-Infusor techniques. It also enhances conventional retraction methods using aluminum chloride and alum, ensuring superior sulcular fluid control. With a quick action time of 3–8 minutes, Ultrapak allows for precise, efficient impressions while providing gentle yet effective tissue displacement. The soft, non-irritating cotton material ensures patient comfort, while its interlocking loops prevent fraying, making packing and removal effortless.
