J Prosthet Dent. 1990 Dec;64(6):635-6. doi: 10.1016/0022-3913(90)90285-k.

Abstract

A precise impression is imperative for the construction of an accurately fitting indirect cast restoration. The putty-wash technique is commonly used in making impressions with silicone elastomers. Errors in manipulation may lead to inaccurate impressions. A technique is presented ensuring exact reseating of the putty impression tray and creation of a uniform wash space, which are essential for accurate results.
