Problems solved by technology

However, the oral microenvironment is complex and affected by many factors
The survey results of the National Dental Institute of the United States show that more than 50% of the existing resin restorations need to be replaced, and the clinical life of the resin bonding restoration is less than 6 years. The annual expenditure for replacing defective bonding restorations in the United States alone is as high as $5 billion
However, due to volume shrinkage during the polymerization of dental resins, the incidence of secondary caries in patients is high, and the wear resistance and mechanical strength of polymer resins are limited, which greatly limits the service life of dental resin materials.

Abstract

The invention discloses a preparation method of an antibacterial and wear-resistant material for filling teeth. The preparation method comprises the following steps: firstly, weighing various raw materials, grinding partial raw materials into fine powder which is 800-1200 meshes in grain size, and uniformly mixing the fine powder, so that a powder mixture is obtained; then, dissolving rest raw materials in double distilled water, and conducting magnetic stirring and uniform mixing, so that a solution is obtained; and adding the powder mixture to the solution, and conducting stirring until the mixture is formed as uniform cream, so that the antibacterial and wear-resistant material is prepared. According to the scheme, the wear resistance of the prepared antibacterial and wear-resistant material is improved by 180%, and the teeth, which are repaired with the use of the material, are firmer and are more durable. The antibacterial and wear-resistant material is simple and convenient to use, free from any toxic and side effects, safe and free from health risks; and the preparation method has the characteristics of being simple in process, easy to operate, high in yield, low in environmental pollution and the like.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial and wear-resistant material for filling teeth. technical background [0002] Teeth are the organs that humans use to chew food. Teeth are the hardest organ in the human body. Generally speaking, teeth are white and hard in texture. The various shapes of teeth are suitable for many purposes, including tearing, grinding food. The pronunciation of human language is closely related to the upper and lower teeth in the front row of the mouth. Teeth are the hardest organs in the human body and are divided into three parts: crown, neck and root. Divided into enamel, dentin, pulp and so on. The main ingredient is calcium hydroxyphosphate: the basic calcium phosphate, the main component of human teeth. [0003] Commonly known as caries and tooth decay, caries is a bacterial disease, which can be secondary to pulpitis and periapical periodontitis, and even cause alveolar bone and jaw inflamma...
