A Comparison of Flexural Strength and Diametral Tensile Strength of a Ceramic-based ORMOCER (registered trademark) and a Conventional Resin-Based Composite

Abstract

The purpose of this bench-top study was to compare the flexural strength and diametral tensile strength of a ceramic based ORMOCER (registered trademark) restorative material to a resin-based composite restorative material. Forty samples of commercially available composite resin restorative materials were assessed for diametral tensile strength (DTS) in accordance with ADA Specification No. 27 and maximum flexural strength (FS) in accordance with ISO 4049. The samples were evenly divided between two different composites including 3M ESPE Filtek Supreme Ultra and Admira Fusion. All testing was completed on an Instron 5943: three-point fexural strength test, compression platens and a load cell of 1 kN. Exploratory data analyses were conducted on continuous data (DST, FS). Analyses of variance (ANOVA) was conducted to assess differences in DTS and FS between the two composites. Statistical significance for all statistical tests was declared at P < 0.05.
