N2 - Development of a biocompatible functional dental occlusion requires maxillo mandibular relation records. Clinical errors in these physical records are mostly caused by protracted clinical setting times. If dimensionally accurate and stable, recently introduced fast and superfast vinlpolysiloxane-based recording materials could reduce these inaccuracies, however such studies have yet not been attempted. This in-vitro study determined the post-polymerization dimensional accuracy of novel fast/superfast vinyl polysiloxane (VPS)-based jaw relation recording materials (JRRM). Four VPS-based JRRMs (Primo, Mark 3, Jetbite, and Defend) with three polymerization variants [regular, fast, and superfast] were investigated for dimensional accuracy. 180 samples allotted to four controls [PR, MR, JR, DR] and eight experimental [fast set (PF, MF, JF, DF); superfast (PSF, MSF, JSF, DSF)] were observed under a stereomicroscope using three different measurement coordinates between the X and Y axes, as specified by american dental association specification number 19. A one-way ANOVA (Kruskal-Wallis) rank test determined median scores, followed by a post hoc (Dunn) test. All probability “p” values were judged to be significant at 0.05. The one-way ANOVA showed significant differences between studied groups, with all regular setting JRRMs except Mark 3 showing the least overall linear changes, followed by super-fast set and fast set. Gp MR showed the highest [Mdn(IQR); 25.19(0.02)], while Gp DSF showed the least [25.00(0.02)] against original die measurements. All fast-set and superfast-set JRRMs showed expansion in terms of physical change. Mark 3 (regular, fast, and superfast) showed clinically unacceptable dimensional changes after 1 h of VPS-based JRRM setting. Defend Superfast was the most accurate material, including regular. Clinically, different variants fulfill dimensional accuracy and stability at various time intervals, therefore different variants may be indicated for specific purposes in fabrication of occlusion for a dental prosthesis.
