Technical Field

The invention belongs to the field of dental materials, and particularly relates to an enamel repairing material.

Background

Teeth are a highly calcified tissue with a morphology that functions to chew, aid in articulation, and maintain facial appearance. The portion of the tooth exposed to the oral environment is enamel, which is the hardest substance in the human body. People who keep teeth healthy often wash their teeth, inevitably damage the enamel on the surface of the teeth, and the enamel needs to be repaired because the enamel is not regenerated.

The invention patent of application number 201811285322.X discloses a preparation method of a modified nano hydroxyapatite composite material for tooth restoration, and discloses a method for preparing a composite material for tooth restoration by adopting hydroxyapatite. However, the hydroxyapatite prepared by the patent realizes the repair through deposition, and the time is too long.

Disclosure of Invention

The invention mainly aims to provide an enamel repairing material, which solves the problem of slow effect of the enamel repairing material.

In order to achieve the technical effects, the invention adopts the following technical scheme:

an enamel repairing material comprises the following components in parts by weight:

the polyamino acid is a copolymer of two of proline, lysine and phenylalanine, and the molecular weight is 2000-2500;

the molecular weight of the polyvinyl alcohol is 6000-;

the hydroxyapatite is rod-shaped hydroxyapatite with the particle size of 50-60 nanometers;

the chitosan is chitosan with ultrahigh deacetylation degree, and the viscosity is 0.25-0.3 Pa.s;

the ultraviolet curing agent is N-methyl, N-phenyl methyl amine butyl acrylate.

When in use, the enamel repairing material is uniformly coated on the damaged part of the tooth, and ultraviolet irradiation curing is carried out to realize the repair of the enamel; the material can also be used as a surface protective layer of an artificial tooth made of organic materials.

The invention has the beneficial effects that: (1) the polyamino acid and the polyvinyl alcohol are used as organic components for photocuring crosslinking, so that the biological compatibility is good, the gum is not stimulated, the speed is high, and the binding property with the original enamel is good.

(2) The addition of chitosan can reduce the erosion of bacteria to the repair material.

Detailed Description

For further understanding of the present invention, the following embodiments are provided to illustrate the technical solutions of the present invention in detail, and the scope of the present invention is not limited by the following embodiments.

An enamel repairing material comprises the following components in parts by weight:

the polyamino acid is a copolymer of two of proline, lysine and phenylalanine, has a molecular weight of 2000-2500, and has good compatibility with enamel;

the molecular weight of the polyvinyl alcohol is 6000-8000, and the degradation can be slowed down after the polyvinyl alcohol is crosslinked with polyamino acid, so that the enamel can be protected for a long time;

the hydroxyapatite is rod-shaped hydroxyapatite, has the particle size of 50-60 nanometers, is the same as the inorganic components in the enamel, and can be gradually deposited on the surface layer of the enamel;

the chitosan is chitosan with ultrahigh deacetylation degree, the viscosity is 0.25-0.3Pa.s, and the corrosion of bacteria to the repair material can be resisted; the ultraviolet curing agent is N-methyl, N-phenyl methyl butyl amine acrylate, and has the characteristic of low toxicity.
