Composite resins are the dental materials are composed of synthetic polymer dispersed in inorganic filler. Composite resins are the mainstream of inlays, but it has become issue about tstimulation of the mucous membrane in the oral cavity due to the remaining unreacted monomer in the inlay and the decreasing the physical properties of the resin itself.
In this work, we create all-biocomposite resin inlay closer to the real tooth, which has high mechanical strength of CNC, low toxicity, and biocompatibility and combined HAp that accounts for 97% of enamel.
