Aim: The present study is aimed to assess the marginal integrity and color stability of provisional restorations fabricated from different autopolymerizing acrylic resins. Materials and Methods: Totally, 60 provisional crowns were fabricated. A mandibular first molar artificial typodont was mounted on a base of dental stone. The mandibular first molar which was mounted was prepared for full cast crown, using the tooth preparation standard principles with shoulder finish line of 1 mm and taper 6°. There were 20 samples in each acrylic resin group: Group I: Polyvinyl-ethyl methacrylate resin, Group II: Autopolymerizing bis-acrylic material, and Group III: Polymethyl methacrylate (PMMA) autopolymerizing resin. Crowns were verified for marginal adaptation using stereomicroscope at a ×40. The color stability was measured using spectrophotometer poststaining period. Results: Autopolymerizing bis-acrylic material group showed minimum mean vertical marginal discrepancy (128.68 ± 18.036 μm) followed by PMMA autopolymerizing resin group (147.49 ± 20.128 μm) and polyvinyl-ethyl methacrylate resin group (172.89 ± 22.118 μm). Analysis of variance demonstrated a statistically significant difference between different autopolymerizing acrylic resins. The color change values did not show any significant difference between the groups on numerous comparisons between different autopolymerizing acrylic resin groups. A statistically significant difference was seen between Groups I and II, Groups I and III, and Groups II and III (P < 0.05). Conclusion: This study concluded that the autopolymerizing bis-acrylic material demonstrated significantly improved marginal integrity when compared to PMMA autopolymerizing resin and polyvinyl-ethyl methacrylate resin.
