Abstract

Aim: This in vitro study aims to investigate the longest possible dimensionally stable interocclusal recording materials among polyvinylsiloxane (PVS), polyether, zinc oxide eugenol, and wax, over a period of 1, 24, 48, 72, and 168 hours. Materials and methods: A stainless steel metal die with known dimensions was used to fabricate 30 samples for 4 different groups (materials) with each group having 5 different subgroups (time interval). Linear dimensional changes were determined by observing the amount of change at six different intersecting fixed points on each sample. While the dimensional change was measured in the percentage using mean and standard deviations, the nature of differences between the materials was determined using one-way analysis of variance (ANOVA). To find which specific groups were significantly different from each other, a Tukey HSD (post hoc) test was employed. The significance of differences was determined at three different levels of p value (≥0.05 = not significant, ≤0.05 = significant, and ≤0.001 = highly significant). Results: Dimensional changes were detected in bite wax (Aluwax) from as early as 1 hour, which relatively increased significantly. Among all materials, PVS (O bite) showed the least dimensional changes at all observed intervals closely followed by polyether (Ramitec) till the 3rd day of observation, differences between the two, however, were significant at 1 hour while being highly significant at remaining time intervals. Both zinc oxide eugenol (Bosworth) and bite registration wax (Aluwax) showed highly significant differences than the original dimensions and with both elastomers. Conclusion: The study concludes that for a delay of up to 7 days, polyvinyl siloxane interocclusal records show the least changes while for a delay of up to 3 days either polyvinyl siloxane or polyether-based interocclusal material can be used. Clinical significance: Polyvinyl siloxane is the material of choice for making interocclusal records presently. There should, however, be no delay in mounting the casts on the articulator irrespective of any type of material used to make an interocclusal record.
