The previous report demonstrated the effects of the environment for storing the alginate impression on the upper dental arch model, in which the dimensional changes were minimized when the impression was stored in water rather than in 100 percent humidity. In this report, dimensional changes of the upper edentulous arch model were examined. The effects of the storing condition varied with the preparation of the impression. The mix with the normal water/powder ratio showed the smallest dimensional changes in all the storing environments ; especially the changes could be minimized in water. When a thinner mix was stored in water, however, extremely larger expansion was found in the cast model, while the dimension tended to decrease in a thicker mix.
