Differential accuracy of elastomeric recording materials and associated weight change.
Six interocclusal recording materials: COE Bite Creme, Blu-Mousse, Correct Bite, Blue Velvet, Memosil C.D. and Ramitec brands, were studied for evaluation of their dimensional stability and associated weight change. The materials were divided into six groups of 10 samples and tested between metal dental casts on the hydroptic test and measurement system. Dimensional changes among the materials were not significantly different. Weight changes among materials were significantly different but did not exceed 0.1%. All 6 brands were highly accurate and dimensionally stable.
