| 内容記述 | Compatibility of five alginate impression materials with two dental plasters and five dental stones were evaluated for dimensional change, detail reproduction and surface roughness. The specimens were stored either in air (23℃±2℃, 60%±10% humidity) or in 100% relative humidity for 30, 60, or 120 minutes after impression was removed. The effect of environmental factors during setting was examined. Four elastomeric impression materials were also examined for comparison. The results obtained were as follows; 1. For impressions stored in air, there were significant differences in the dimensional change of cast in each product. However, there were few differences observed in 100% humidity. 2. Regarding dimensional change, the limit of sustained impression time was 30 minutes. 3. The detail reproduction was inferior with time passage after the impression was removed. 4. Surface roughness decreased with time passage. 5. The surface of casts of some impressions produced in 100% humidity were rougher than those produced in air. 6. It is generally said that to keep impressions in 100% humidity is the optimal method. However, some materials were not appropriate for this method. 7. Elastomeric impression materials were stabile in dimensional accuracy and detail reproduction up to 120 minutes. 8. Surface roughness of casts made from elastomeric impression material decreased with time passage. | |||||||
