Visible, light-cured, radiopaque, restorative material designed for posterior restorations including occlusal surfaces. High fill ratio (87.0wt%, 74.5vol%) reduces polymerisation shrinkage and shrinkage stress, while increasing compressive and flexural strength. Complete polymerisation at 4mm depth of cure. Translucency creates aesthetic shades unaffected by surrounding intra-oral colour. Sustained fluoride release.
