What is the recommended method for removing an impression from the mouth?

The recommended method for removing an impression from the mouth is with a snap. This technique is considered effective because it helps to break the seal created by the impression material against the soft tissues of the mouth. A quick, snapping motion can minimize discomfort for the patient and help ensure that the impression does not distort. This method allows the impression to come out cleanly and without additional stress on the surrounding tissues.

In contrast, other methods such as slowly pulling away, using a gentle twist, or lifting gradually can lead to potential issues. A slow pull might not break the seal adequately, while twisting could distort the impression or cause discomfort. Gradual lifting could also lead to uneven pressure on the impression, increasing the risk of distortion as well.
