The invention discloses a dental restoration filling material containing a special function monomer. The dental restoration filling material is prepared from, by mass, 5%-30% of bisphenol A glycidy methacrylate, 5%-20% of TEGDMA, 5%-20% of the special function monomer, 1%-10% of fluorine-containing urethane acrylate, 50%-70% of porcelain cement, 0.5%-1% of camphorquinone and 0.5%-1% of 2-(dimethylamino)ethyl methacrylate. The dental restoration filling material has the greatest advantages that hydroxyethyl methylacrylate and phosphate of the function monomer are synthesized, so that the Bis-GMA viscosity is lowered, and the operating performance is improved; meanwhile, the dental restoration filling material can be reacted with substances such as calcium ions in teeth to form chemical bonds, and the adhesive force between the restoration material and the tissue of the teeth is increased; due to the existence of fluorine elements, the antibacterial property of the teeth can be greatly improved. By testing through tests, the bending strength is 93-120 MPa, and the tensile strength is 9-15 MPa. The invention further discloses a preparation method of the dental restoration filling material containing the special function monomer.
