An impression is an imprint produced by existence of pressure of one thing into another surface. And this indicate an active role not a passive one and the clinician should understand that impressions are made, not taken. Mucostatic or passive impression was first proposed by Richardson and later popularized by Henry Page. A survey was conducted in dental colleges to get to know about the impression techniques and impression material used by the dental surgeons. It is discouraging to know that 35% of dental surgeons are using base plate custom trays to record secondary impressions. 10% are still using the alginate for secondary impressions. A supportable technique for recording full denture impressions is put forwarded for impression
