Hydroxyapatite Whiskers Based Resin Composite versus Commercial Dental Composites: Mechanical and Biocompatibility Characterization

Figure 6

Schematization of hydroxyapatite whiskers/matrix interaction. Three fundamental components can be highlighted in the composite: the resin which consists predominantly of Bis-GMA which is shown in blue, the filler of hydroxyapatite (HA) with needle-like morphology (whiskers) and micrometric size, and the voids in white.
