(a) HAADF-STEM structural analysis of the Ca-MDP nanolayering showing changes in the directions and intercrossings of the Ca-MDP nanolayers on the X- and Y-axes represented with different arrows’ colors. (b) Nanomechanical interlocking hypothetical model showing the empty spaces in between (red hand pointer) that could act as interlocking sites for the other contained resin monomer components (e.g., Bis-GMA, HEMA, and TEGDMA) during the 10 s reaction time when applied clinically.
