Act on to ISO 4823 about physical property of rubber Rubber Impression Materials for dental treatment to three products that consistency of Putty·Heavy·Light body is different, the elastic recovery rate, compressive strain to search about change of physical property by storage temperature of addition silicon Rubber Impression Materials and executed an estimation experiment. Evaluated about special quality of the elastic recovery rate and compressive strain that is concerned in effect of consistency and permanent deformation that influence to fine absence sages and saints by addition silicon Rubber Impression Materials' storage temperature, and got following result. 1. Store-owner by storage temperature of Vonflex Putty, Vonflex Heavy, Vonflex Light displayed difference that d keeps in mind and (p<.05), size of average diameter that is measurement of store-owner degree as storage temperature of Rubber Impression Materials is high was shown decrescent aspect. 2. Elastic recovery rate by storage temperature of Vonflex Putty displayed difference that was not shown difference that keep in mind, and keeps in mind in Vonflex Heavy, Vonflex Light aspect that the elastic recovery rate increases as (p<.05), storage temperature of Rubber Impression Materials is high was seen. 3. Difference that compressive strain by storage temperature of Vonflex Putty was not shown difference that keep in mind because has similar value and keeps in mind in Vonflex Heavy, Vonflex Light appeared and (p<.05), Vonflex Heavy when do 5℃ storage and when do 22℃ storage between difference that keep in mind be, and Vonflex Light when do 5℃ storage and when do 45℃ storage between difference that keep in mind.
