What should be done after an ear is filled with impression material?

After an ear is filled with impression material, the appropriate action is to push firmly on the concha several times. This technique ensures that the impression material accurately captures the contours of the ear canal and the outer ear. By applying pressure to the concha, you help to achieve a more precise fit, which is crucial for the effectiveness of the hearing aid or ear mold being produced from the impression.

Pushing on the concha also helps to create a seal around the impression material, minimizing any potential air pockets that could distort the final impression. This process is particularly important to ensure that the final product closely matches the unique anatomy of the patient's ear, which will be essential for comfort and optimal sound transmission.

Other actions, such as removing the impression immediately or letting it sit without any manipulation, may not produce a reliable result as they do not allow for the necessary precision to be achieved in the impression process. Confirming that the material is cool is generally not relevant to the fitting and comfort of the impression but rather a manufacturing concern. Therefore, applying pressure on the concha enhances the quality of the impression taken.
