Abstract
It has previously been reported by the authors that the impression pressure was quantified as the final force occurring during impression. In this study, the influence of the type of tray on the impression pressure of twelve alginate materials was investigated. Further, the relationship between consistency of an alginate mix and the impression pressure was examined.
The impression pressure decreased with increases in the opened area of the tray. The decreasing rate of the pressure depended on the materials used. There was an inverse correlation between the consistency and the impression pressure, but the correlation coefficient differed with the type of tray apparently due to the effect of the characteristics of the materials.
