The invention provides a tooth
adhesive system based on a new hydrophobic adhesion concept. The tooth
adhesive system comprises a single-component
adhesive and a bi-component adhesive, wherein the necessary components of the single-component adhesive and the bi-component adhesive are a hydrophobization
reagent, solvents, hydrophobic polymeric monomers and photopolymerization initiators. The
system is characterized in that hydrophobic modification is firstly carried out on tooth surfaces in the adhering process, so that the tooth surfaces are converted from hydrophilic surfaces to
hydrophobic surfaces. The system has the beneficial effects that the polymeric monomers in the adhesives can fully infiltrate demineralized
dentin matrices, so that adhesive monomers fully infiltrate the demineralized
dentin matrices, and a uniform and stable
mixed layer is finally formed after in-situ
polymerization, thus obviously improving the immediate
adhesion strength, improving the long-term
adhesion strength of
dentin by several times, obviously reducing the nano
leakage rate of the
mixed layer and radically improving the durability of adhesion and restoration; the system has the effect of obviously improving the immediate and long-term
adhesion strength of dentin and enamel and the durability of tooth
prosthesis adhesion and has obvious dentin immediate sealing effects and good dentin desensitizing effects.
