Simple, Accurate Impressioning That Is Gentle on Gingival Tissues

N. Summer Lerch, DDS, FAGD, AAACD

The field of dentistry is evolving. Traditionally, impression-taking has involved applying astringents and hemostatic agents, packing cord, and forcibly challenging the gingival tissues. Today, however, a unique new system has made these time-consuming and sometimes harmful processes obsolete. The NoCord VPS™ self-retracting impressioning system from Centrix, Inc. (, a company led by dental innovator Dr. William B. Dragan, brings a highly effective “gentle displacement” impression material to the dental marketplace. This system allows cosmetic-minded clinicians to easily take highly accurate impressions while causing no harm to sensitive gingival tissues. NoCord VPS affords a clean capture without extra tissue retraction, providing an easy-to-read margin and allowing a perfectly fitted restoration. Moreover, there is no need to learn a new procedure, as a traditional wash-and-tray technique can be used.

Key Takeaways

• NoCord is a one-step impressioning and retracting system designed for simple, noninvasive, and accurate impressions. It spares gentle gingival tissues the trauma of packing cord.

• With no cord to pack and without the need for a separate retraction procedure, the system saves time and money for the dentist and staff.

• NoCord VPS Wash retracts tissue away from the tooth and achieves hemostasis and accurate marginal detail. Good color contrast makes reading the margins easy. NoCord VPS MegaBody tray material has a unique setting profile that enables it to effectively “drive” the Wash into the sulcus, causing retraction.
