AB  - Novel branched silicone methacrylate was developed. The mechanical and biological properties of the resin system were investigated to select the formula proportion with the best overall performance. The novel silicone-containing monomers were combined with an incremental sequence of glass filler concentrations in commonly used
Bis-GMA/TEGDMA (50/50, wt./wt.) dental resin systems. Physicochemical properties, surface properties, antibacterial adhesion effect, anti-biofilm effect, protein adsorption, and cytotoxicity were evaluated. The results
showed that BSMs did not affect the double bond conversion of dental resin, but could reduce volumetric shrinkage (<i>p</i> < 0.05). The BSM containing resins can resist protein and bacteria adhesion (<i>S. Mutans</i>) because it has
increased hydrophobicity and a lower free energy surface (<i>p</i> < 0.05). However, there were no statistically signifi-
cant differences in cytotoxicity, surface roughness, and double bond conversion rate. Overall, the results indicate
that changes in a material’s properties are not strictly proportional to its composition. Synthetic silicone resin
methacrylate can reduce the polymerization shrinkage, have low surface energy and anti-adhesion properties. Silicone composite resin containing 70% matrix has the best comprehensive properties. The silicone methacrylate
composite represents an innovative method to improve the properties and reducing secondary caries.
