Use the Double-Cord Packing When Taking Impressions
You may have reasons for not using a double-cord packing technique when taking impressions. Here at The Art Of Aesthetics cosmetic dental laboratory, we often receive impressions with a single cord or no cord at all. The double-cord technique is not a luxury but a necessity for us to be able to distinguish margins from the gum. This simple technique will minimize most of the troubles associated with remakes and adjustments. It will benefit everyone involved: the doctor, patient, and laboratory.
Please use the double-cord packing when taking impressions, whether they are digital or non-digital.
Even digital impressions from intraoral scanners such as 3Shape Trios, Cadent iTero, 3M True Definition, Sirona Connect (Cerec), or Medit, double-cord packing will help us to define margins more clearly.
Why use the double-cord impression technique?
By using double-cord packing, you will save time and trouble for taking another impression or for the necessity for remakes due to the lack of visibility of margins.
When using the double-cord packing, you can see more patients instead of re-taking impressions. Your patient will not have to return to your office to remove the temporary crown or go through the hassle of taking another impression.
Please pack the small cord first, then the large cord on top of it, still under the margins. Please wait for 5-6 minutes before removing them and taking impressions. This is true when taking Trios, iTero, True Definition, Cerec, or other digital impressions.
Please use the double-cord packing when taking impressions.
It will help us do our job expertly, since there will be absolutely no need for guesswork when identifying margins. It will help to eliminate most remakes with new impressions due to short or open margins. Some may reason that digital impressions (e.g., iTero or Trios) don’t have to use the double-cord packing, but as far as the restoration laboratory is concerned, it doesn’t make any difference between digital or non-digital impression: double-cord packing will help to reduce, if not eliminate, remakes.
