Preparation method of anti-bacterial tooth growing and repairing material

Abstract

The invention belongs to the field of inorganic nonmetal materials, particularly belongs to a preparation method of an anti-bacterial tooth growing and repairing material, and relates to a growing and repairing anti-bacterial tooth material used in an alveolar cavity without a tooth or on the surface of an incomplete tooth. The anti-bacterial tooth growing and repairing material comprises the following main ingredients: apatite crystals containing silver, copper, calcium and phosphorus, titanium oxide and zinc oxide. Under the regulation and control effect of a binary polyelectrolyte compound consisting of water-soluble cationic polyelectrolyte and organic polyatomic acids, ingredients of the tooth growing and repairing material are synthesized with soluble calcium salt, soluble phosphate, copper sulfate and silver nitrate salt, a crystal natural growing method is used, and a dental matrix comprising the apatite crystals containing the silver, the copper, the calcium and the phosphorus, the titanium oxide and the zinc oxide are subjected to adsorption reaction fully. Crystalline grains of the anti-bacterial tooth growing and repairing material are in nanoscale, the copper and the silver can be fine and are uniformly distributed in the tooth growing and repairing material, diameters of metal particles are 30-80 nanometers, and the anti-bacterial tooth growing and repairing material can release anti-bacterial elements quickly and continuously.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials, in particular to a preparation method of an antibacterial tooth growth restoration material, which relates to an antibacterial tooth material for growth and restoration in the alveolar of missing teeth or on the surface of incomplete teeth. The main components are silver, copper, calcium and Apatite crystals of phosphorus, titanium oxide and zinc oxide. Background technique [0002] At present, the demand for dental oral materials is increasing year by year. Among them, dental oral materials such as titanium alloy and nickel-chromium alloy are in great demand in life. With the improvement of people's living standards, artificial tooth materials can maintain the same color as natural teeth. It is very important. Therefore, it is usually necessary to attach a layer of enamel to the surface of titanium alloy and nickel-chromium alloy. The enamel layer is the white translucent hard tis...

Problems solved by technology

However, the inventive material does not contain antibacterial elements, so it does not have antibacterial and antibacterial effects. At the same time, the main component of the patented tooth growth restoration material is not hydroxyapatite. There is a certain gap in compatibility with the human body, which may easily cause discomfort to the human body.
