Marginal fidelity of crowns fabricated from six proprietary provisional materials.

Abstract

STATEMENT OF PROBLEM: The most important requirement for an interim crown is suitable marginal adaptation.
PURPOSE: This in vitro study compared vertical discrepancies of margins for complete crowns made with six provisional materials (Provipont, Protemp Garant, Unifast LC, Triad VLC, Splintline, and Jet).
MATERIAL AND METHODS: A direct technique was used to fabricate 60 provisional complete crowns on prepared molars with a polyvinyl siloxane impression and a vacuum-formed polypropylene sheet as matrices. A measuring microscope was used to measure vertical marginal discrepancies at x 100. Data were analyzed with Kruskal-Wallis one-way analysis of variance and Mann-Whitney U tests (alpha = 0.05).
RESULTS: Significant differences were found between resinous materials tested (p = 0.0002) and multiple comparisons tests indicated no significant difference between Splintline and Protemp Garant; Provipont, Unifast LC, and Triad VLC; and Unifast LC, Triad and Jet provisional materials.
CONCLUSIONS: This study indicated that provisional crowns fabricated with Splintline and Protemp Garant interim restorative materials recorded the least marginal discrepancies.
