Abstract
Mechanical properties of dental restorative materials are important for clinical success in prosthodontic care. However, open data on the mechanical properties of these materials are limited. This article provides data on the flexural strength and elastic modulus of dental composites in practical use for design/computer-aided manufacturing (CAD/CAM) systems. Eight brands of composites were subjected to deterioration tests: immersing in water at 37 °C for one day or seven days, or thermocycling (TC) in water at temperatures between 5 °C and 55 °C for 5000 or 10,000 cycles. The mechanical properties of the samples were measured by using a three-point bending test according to ISO 6872. The obtained values were statistically analyzed using one-way analysis of variance (ANOVA), followed by Tukey multiple comparison tests.
Highlights
Data on changes in flexural strength and elastic modulus of dental composites in practical use for design/computer-aided manufacturing (CAD/CAM) composites after deterioration tests
Eight brands of composites were subjected to deterioration tests: immersing in water at 37 C for one day or seven days, or thermocycling (TC) in water at temperatures between 5 C and 55 C for 5000 or 10,000 cycles
The data can be helpful for dentists to choose the dental CAD/CAM composites for clinical treatment
Summary
All data and supplementary files are available within this article. Value of the data The data can help obtain the mechanical properties of the dental composites in practical use. The data can be helpful for dentists to choose the dental CAD/CAM composites for clinical treatment. The data can be useful for developing dental materials. The data can be compared with that on dental restorative materials, including ceramics and composites. Changes in the values due to the deterioration tests are statistically analyzed in each composite by ANOVA, followed by Tukey multiple comparison tests; the results are shown in Figs. 1 and 2
