title: Reproducibility of occlusal contacts relative to mounting cast variables.
abstract: This study evaluated the accuracy of occlusal contacts relative to the mode in which casts are mounted. Specifically, the direct effect on occlusal contacts was assessed with respect to: (a) the type of mounting stone used; (b) the amount of material used relative to the distance between the mounting plate and the cast base; and (c) the presence or absence of a restriction of the articulator's vertical opening. A 3 x 2 x 2 factorial analysis of variance and a Dunn's Multiple Comparison Procedure (P < .05) showed that one of the three mounting stones was statistically significantly less accurate in reproducing occlusal contacts when a distance of 19 mm existed between the cast and the articulator, regardless of the existance of articulator restriction.
