Abstract

The invention discloses a tooth filling composite material and a preparation method thereof. The preparation method comprises the steps that nano silicon powder, ethyl acetate, hydroxy cyclohexyl acetophenone and an acrylate monomer are mixed, after a dispersion medium is steamed out, illumination solidification is conducted, after crushing, a composite filler is obtained, and dicalcium phosphatemonohydrate, anhydrous dicalcium phosphate, dicalcium phosphate dihydrate, calcium phosphate dibasic anhydrous, anhydrous magnesium sulfate, sodium chloride and sodium bicarbonate are mixed and then ground to obtain mixed powder; the mixed powder, solvent, a binding agent, fibrefill, a biological filler and the composite filler are mixed to obtain the tooth filling composite material. The problemsare solved that setting time of traditional filling materials is longer, and the compressive strength of the traditional filling materials is relatively inadequate.

Description

technical field [0001] The invention relates to the field of dentistry, in particular, to a tooth filling composite material and a preparation method thereof. Background technique [0002] Clinically, doctors often choose different materials to fill the cavity according to the location of the affected tooth, the location of the cavity, the magnitude of the occlusal force, as well as the patient's health and aesthetic requirements. Currently, the commonly used materials are: silver amalgam, composite Resin and glass ionomer complex. [0003] Silver amalgam is a commonly used restorative material with a history of more than 150 years. Its safety has been well established. So far, there is no direct evidence that it has adverse effects on human health, and it has been widely used in the general population. The incidence of allergic reactions is extremely low. Silver amalgam has the largest compressive strength, hardness and wear resistance, and its performance is stable. It is...
