Pak Oral Dental J Jan ;36(1):161-3.

The objective of this study was to survey the impression technique used by the dental professionals of different institutes. Impression making is an important step in fabricating complete dentures. 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.
