Abstract
The present study is desined to Silicone Rubber Impression materials on manipulated condition, that is impression thickness, making and remove of impression its time elapse of mixing, have influence on occulusal surface and axial surface used with Holography.
As the results of these effort, the following conclusions were obtained.
1. This study is good method used with the Holography. This method can measured deformation and infinitesimal displacement of dental materials, don't touch the object and that can observe with the bodily eye.
2. Silicone Rubber Impression materials showed various displacement volume severally on manipulated conditions.
3. Impression surface of axial surface condition that impression thickness 1, 0mm, making of impression after 75 seconds, removed after 5 minutes its time elapse of mixing showed minimum. And the state added between occulusal surface and axial surface, that condition showed minimum displacement volume too.
4. Silicone Rubber Impression materials surface keep on after 60 minutes displacement all condition that this study established.
