The best way to remove a hydrocolloid impression from the patient's mouth is____________?
Correct answer: C. Sudden jerking of the impression to prevent tearing
- A. Slight rocking of the impression to disengage it from the undercut
- B. Wetting the periphery of the impression with moist cotton to break the peripheral seal
- C. Sudden jerking of the impression to prevent tearing
- D. Supporting the impression along with the tray to prevent disengaging of the tray alone
Explanation
A hydrocolloid impression should be removed with a quick, decisive movement along the path of removal, which reduces prolonged deformation and tearing around undercuts. Gentle rocking or slow removal can distort the elastic impression.
