Impression Techniques in Prosthodontics

Abstract

A successful dental prosthesis or a restoration is mainly dependent on the accuracy of the dental impressions. An impression is an imprint produced by „the pressure of one thing upon or into the surface of another‟ or the negative likeness. It is not technically possible or desirable to fabricate prostheses or restorations directly in the patient‟s mouth. Therefore it is essential to obtain a cast or a model which must be accurate replicas of the denture bearing area or the prepared tooth/teeth in the mouth. 1
