Abstract

The invention discloses a tooth repair filling material and a preparation method thereof. The preparation method comprises the following steps: calcium dihydrogen phosphate monohydrate, anhydrous calcium dihydrogen phosphate, calcium hydrogen phosphate dihydrate, anhydrous calcium hydrogen phosphate, anhydrous magnesium sulfate, sodium chloride and sodium bicarbonate are mixed and ground, and mixed powder M is obtained; the mixed powder, a solvent, an adhesive, fiber filler and biological filler are mixed, and the tooth repair filling material is obtained. The problems of longer setting time and relatively insufficient compressive strength of a traditional filling material are solved.

Description

technical field [0001] The invention relates to the field of dentistry, in particular to a filling material for tooth restoration 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. ...
