Problems solved by technology

However, if you use antibacterial mouthwash frequently, just like using oral antibiotics for a long time, the "ecological environment" in the oral cavity will be destroyed, which may lead to oral inflammation and other diseases over time
Yet there is no dental orthopedic silk report with antibacterial function at present

Embodiment Construction

[0049] Further description will be given below with examples of the present invention.

[0050] The novel antibacterial dental orthopedic wire provided by the invention is characterized in that it is composed of titanium-nickel alloy phase and granular pure silver (ie Ag). The mass ratio of titanium to nickel in the titanium-nickel alloy (ie Ti-Ni alloy) phase is 45:55-55:45, and the rest is a small amount of impurities. The impurities include oxygen, carbon, hydrogen, etc. The oxygen content of the material is less than 500ppm, the carbon content is less than 700ppm, and the hydrogen content is less than 500ppm. The impurity content is very small, which can be ignored in the composition percentage of the material. It also has basically no impact. The content of the granular Ag is 0.1%-20% by mass, and it is evenly dispersed in the titanium-nickel alloy phase. The preferred range of Ag content is 0.1%~3.5%, 9%~11%, 13%~16%, 18%~20%, and the preferred content is 0.1%, 1%, 2.8...

Abstract

The invention relates to an antibacterial orthodontic thread and a manufacturing method thereof. Granulated silver is distributed in a traditional Ti-Ni alloy orthodontic thread through a smelting method, a powder mixing and sintering method or a self-propagating high-temperature synthesis, and then the orthodontic thread has an antibacterial effect, so that the problem that a patient needs to use antibacterial mouth wash for a long time during the orthodontic process can be avoided.

Description

technical field [0001] The invention relates to an antibacterial dental orthopedic wire and a manufacturing method thereof. Background technique [0002] The oral cavity is an open body cavity exposed to a wide range of biological, chemical and mechanical stimuli. The microorganisms in the oral cavity include bacteria, fungi, viruses, etc. There are more than 400 kinds of bacteria alone, and most of them exist in a symbiotic form. Pressurize and bandage for about one day after orthodontic surgery to prevent the wound from bleeding to form hematoma or secondary infection. From the next day after the operation, you must pay attention to oral hygiene, such as gargling with mouthwash containing antibacterial drugs, and spit it out after a few minutes to avoid oral infection. However, if you use antibacterial mouthwash frequently, just like using oral antibiotics for a long time, the "ecological environment" in the oral cavity will be destroyed, which may lead to oral inflammat...
