Use of Irreversible Hydrocolloid to Blockout Interproximal Spaces for an Easy Impression Taking

Abstract

Making impression to obtain an accurate working cast needs to use accurate impression materials such as polyether. On the other hand, polyether cannot be used easily in places with undercut such as excessive interproximal spaces and under the pontics of fixed partial dentures as it may be locked in these free spaces. In this article, a method is presented to blockout interproximal spaces in order to minimize distortion and to facilitate impression removal from the mouth.
