How to Take Wash Impression for Full Denture

Ensure the tissue side is clean and dry. Trim any over-extended areas if necessary.

Apply adhesive to intaglio

Mix a low-viscosity (wash) impression material and evenly coat the tissue-bearing surface of the denture.

Place the denture in the patient’s mouth and have them gently close into their normal bite.

Guide the patient through movements (e.g., smile, pucker, move tongue) to capture the full extent of the borders.

Let the impression material fully set without disturbing the denture.

Carefully remove the denture, check for accuracy, and ensure all tissue areas and borders are properly captured.

Disinfect the impression before sending it to the lab.
