Background: Hardly any single clinical procedure is accomplished without the use of any type of polymer which denture bases and teeth, custom trays, impression materials, core build up materials, temporary restoratives, soft liners, cementing/luting materials, and maxillofacial prostheses, etc. In comparison to heat cure acrylic resin, self cure acrylic resin has inferior physical properties owing to lesser degree of polymerization.
Materials and Method: Total 60 specimens were evaluated for flexural strength for both auto polymerizing acrylic resin and polycaprolactone. Evaluation of flexural strength was done with 3 – Point bending tester. For statistical evaluation One way ANOVA and Tukey – Kramer multiple comparison tests were used.
Results: There was statistical significant difference found between different thickness of auto polymerizing resin as well as polycaprolactone group. But there was no statistically significant difference present in flexural strength in 1.5mm, 2mm and 2.5mm thickness between Polycaprolactone group and Auto polymerizing acrylic resin group.
Conclusion: Both auto polymerizing acrylic resin and polycaprolactone shows almost same flexural strength at difference thickness. So, polycaprolactone may be used as an alternative to auto polymerizing acrylic resin.
