Piezography used mainly within France and Spain is one of the functional approaches to obtain the proper denture space in complete and partial dentures. The purpose of this study was to find impression materials suitable for Piezography. Five subjects and five operators (mean age: 27.0±1.5 years) were selected for the study. Eleven kinds of commercially available soft impression materials were examined by using Visual Analog Scale (VAS) on six items, irritation to oral soft tissues, operability, aptness to pronounce and to hear words, hardening time, and surface smoothness.<BR>As a result, FITT (Kerr Co.) used in the original Piezography was the best impression material. Tissue Conditioner (Shofu Inc.) and Evatouch H-type (Neo Dental Chemical Products Co.) also obtained high evaluation among impression materials tested in this study. In consideration of economic efficiency, it was suggested that Tissue Conditioner was the best impression material for Piezography in Japan.
