The power vacuum mixers designed to mix dental investment powders automatically have recently been developed. In this study, it made comparative study from setting expansion, thermal expansion, scanning electron microscopy, electron probe micro analyzer, surface roughness and compressive strength by the one that pre-mixing of phosphate-bonded investment was done with this mixer all automatic process and what had been done by hand mixing. Moreover, the influence by the difference of the quantity of powders was investigated. As a result, The setting expansion had significant difference.
