Description
This is an Accepted Manuscript of an article published by Taylor & Francis in Computer Methods in Biomechanics and Biomedical Engineering on 19 May 2017, available at https://doi.org/10.1080/10255842.2017.1293664.
Abstract
The objective of this study was to assess the effect of silica nano-filler particle diameters in a computer-aided design/manufacturing (CAD/CAM) composite resin (CR) block on physical properties at the multi-scale in silico. CAD/CAM CR blocks were modeled, consisting of silica nano-filler particles (20, 40, 60, 80, and 100 nm) and matrix (Bis-GMA/TEGDMA), with filler volume contents of 55.161%. Calculation of Young’s moduli and Poisson’s ratios for the block at macro-scale were analyzed by homogenization. Macro-scale CAD/CAM CR blocks (3 × 3 × 3 mm) were modeled and compressive strengths were defined when the fracture loads exceeded 6075 N. MPS values of the nano-scale models were compared by localization analysis. As the filler size decreased, Young’s moduli and compressive strength increased, while Poisson’s ratios and MPS decreased. All parameters were significantly correlated with the diameters of the filler particles (Pearson’s correlation test, r = −0.949, 0.943, −0.951, 0.976, p < 0.05). The in silico multi-scale model established in this study demonstrates that the Young’s moduli, Poisson’s ratios, and compressive strengths of CAD/CAM CR blocks can be enhanced by loading silica nanofiller particles of smaller diameter. CAD/CAM CR blocks by using smaller silica nano-filler particles have a potential to increase fracture resistance.
