Purpose:
The purpose of this study was to evaluate the resistance to compression after setting of several elastomeric interocclusal recording materials.
Materials And Methods:
Testing of the resistance to compression after setting was performed following a modification of the method described in specification No. 19 (4.3.6) of the A.D.A., for the elastomeric impression materials-1 cylindrical stainless steel mold with an internal diameter of 20 mm and a height of 20 mm was constructed. Mixing of the interocclusal registration media was conducted according to manufacturers' instructions, and the materials were injected into the mold. Two subsequent loads, one of 100 g/cm2 and a second of 1000 g/cm2 were exerted on each sample. The deformation of each was calculated using a vertical traveling micrometer microscope with an accuracy of +/- 0.001 mm.
Results:
One-way ANOVA revealed significant differences among the materials (F=331.58, p <0.0005). Tukey's HSD (p <0.05) test was used to determine the significant differences between the materials.
Conclusions:
Polyvinylsiloxane Blu Mousse displayed the greatest resistance to compression, as compared to other elastomeric interocclusal recording materials tested.
