Preparation:

• Select the appropriate compound: Choose the right type of impression compound based on the patient’s needs (working and setting temperature).
• Heat the compound: Using a flame or water bath, heat the impression compound until it becomes soft and pliable. The material should be malleable but not too hot to burn the patient.

Loading the Tray:

• Fill the impression tray: Load the softened compound into a suitable impression tray. Ensure that the tray is filled evenly, covering the entire surface area of the tray, and leave a slight excess to ensure a complete impression.

Taking the Impression:

• Place the tray in the patient's mouth: Gently place the tray in the patient's mouth and press it into place, making sure it conforms to the dental arch and captures the details of the gums and teeth.
• Allow it to set: The compound will cool and harden as it contacts the oral tissues. This process usually takes a few minutes. During this time, keep the tray in place until the material has completely set.

Removing the Impression:

• Once the compound has solidified, carefully remove the impression tray from the patient’s mouth. The material will maintain its shape, capturing a clear imprint of the oral structures.
• Inspect the impression: Check for any distortions or areas that may require additional material for a more accurate reproduction.

Post-Impression Handling:

• Disinfection: If necessary, disinfect the impression following your office’s infection control protocols.
• Pouring the model: The impression can be used for making diagnostic or working models. Pour the impression with gypsum or another suitable material immediately after it is taken to avoid any dimensional changes.

Cleaning the Equipment:

• Clean any trays and tools used for handling the compound after use. The compound can be reused by reheating if necessary.
