Embodiment 1

[0075]Example 1 Detection of Magnetic Field Distribution of Micromagnetic Orthodontic Accelerator

[0076] Figure 8 Shown is a rat micro-magnetic orthodontic accelerator designed by the applicant to verify the effect of the scheme of the present application. The micro-magnetic orthodontic accelerator of the above-mentioned rat is placed on a horizontal plane, and a high-precision industrial gauss meter driven by an external motor is used to measure the micro-magnetic orthodontic accelerator. The three-dimensional spatial magnetic field distribution of the magnetic orthodontic accelerator, the magnetic field distribution in the horizontal direction and the magnetic field distribution in the vertical direction are measured respectively, and the results are as follows: figure 1 and figure 2 shown.

[0077] After the magnetic field strength test, it can be seen that the micro-magnetic field strength generated by the micro-magnetic orthodontic accelerator is about 10mT, which i...

Embodiment 2

[0078] Example 2 Micromagnetic Orthodontic Accelerator Accelerates Rat Teeth Movement

[0079] 1. Installation of the orthodontic device: anesthetize the rat by intraperitoneal injection, install orthodontic tension springs on both maxillary teeth of the rat, the front end of the spring is ligated with the incisors as anchorage, the back end is ligated with the first molar, and one on each side is installed. The root tension spring applied 100g orthodontic force (medium gravity) to the bilateral first molars of the rats, and the force was maintained for 4-6 weeks.

[0080] 2. Application method of micro-magnetic orthodontic accelerator: 15 rats in the experimental group and control group were given inhalation anesthesia at the same time, and on the basis of maintaining sedation, the upper and lower incisors of the rats were opened with rubber bands to expose the posterior teeth. The micro-magnetic orthodontic accelerator (experimental group) was placed horizontally into the mo...

Embodiment 3

[0081] Example 3 Micromagnetic Orthodontic Accelerator Effect Detection Index

[0082] 1. Using micro-CT scanning to analyze the moving distance of the maxillary first molars of the rats in the experimental group (micro-magnetic acceleration group) and the rats in the control group, and analyze the moving speed of the teeth, some of the results are as follows Figure 4 shown.

[0083] Animal experiments further verified the significance of the micro-magnetic field effect of the new micro-magnetic orthodontic accelerator. In animal experiments, the moving distance of the first molars in the experimental group was significantly increased compared with the control group under the action of the micro-magnetic field. Statistically calculate the average value of the tooth movement distances of all rats in the experimental group, and statistically calculate the average value of the tooth movement distances of all the rats in the control group to obtain Figure 5 As shown in the stat...

Abstract

The invention provides a micro-magnetic orthodontic accelerator, and relates to the technical field of medical instruments, the micro-magnetic orthodontic accelerator uses the principle that an induced magnetic field can be generated between magnets to carry out exogenous magnetic field compensation on teeth and recover a normal magnetic field microenvironment required by periodontal tissues; the magnetic field reconstruction device is favorable for improving metabolism reconstruction of local periodontal soft and hard tissues subjected to orthodontic treatment, shortening the treatment period and reducing the occurrence rate of complications, and meanwhile, physiological-level magnetic field reconstruction does not cause side effects to a human body. The micro-magnetic orthodontic accelerator is simple in structure, small in size, convenient to wear and store, comfortable to wear and high in patient compliance. The novel micro-magnetic orthodontic accelerator can be used only by being worn in the oral cavity, and is multiple in use scene, convenient to use and easy to realize clinical popularization.

Description

technical field [0001] The present application relates to the technical field of medical devices, and in particular, to a micro-magnetic orthodontic accelerator and a method for accelerating tooth movement. Background technique [0002] Orthodontics can not only improve the situation of uneven teeth, but also improve the appearance of people's faces. Therefore, more and more people choose to have orthodontics. The two biggest problems facing the current clinical orthodontic treatment are the long treatment period and complications such as bone cracking, bone fenestration, tooth damage, and root resorption brought about by the long-term treatment process. and patients have caused certain difficulties. [0003] In order to shorten the treatment period of orthodontics, the movement of teeth can be accelerated during the treatment process. At present, the commonly used schemes to accelerate the movement of teeth are mainly divided into three categories: surgery (corticotomy), p...
