PHOTOPOLYMERISABLE RESIN COMPOSITE AND USE THEREOF

摘要

The present invention relates to a photopolimerisable resin composite with a higher filler particle content and a resin matrix of dimethacrylate monomers which are polymerised by free radical reaction initiated by the synergy of photoinitiator systems based on camphorquinone (CQ) and (2,4,6-trimethylbenzoyl)diphenylphosphine oxide (TPO or MAPO). In addition, the invention relates to the use of this photopolymerisable resin composite to manufacture odontological resin materials, such as sealants, composite resins of low or high viscosity and photoactivated or dual curing resin cements. The photopolymerisable resin composite of this invention makes it easier to imitate the colouring of natural teeth, since it achieves a wider range of brighter colours for odontological restoration materials.
