Technical Field

The invention belongs to the field of medical appliances, and relates to an orthodontic appliance capable of measuring internal deformation in real time.

Background

In the field of orthodontic repair, a plurality of scenes in which the deformation of an appliance in the mouth needs to be monitored in time to evaluate the repair effect of a patient are involved. However, because the application environment in the mouth is narrow, a large-scale instrument cannot be used for measurement, or because the instrument is close to a human body, a radioactive scanning and measuring instrument cannot be used. In the past, in the face of the replacement and adjustment of the appliance, the result is obtained by adopting in vitro multi-cycle and multi-stress condition test of samples in advance, so that the adjustment cycle of a patient is estimated, the intraoral instant deformation of the appliance cannot be accurately measured aiming at diversified individual patients, and the appliance can be scientifically replaced and adjusted.

Therefore, a device for measuring the instant deformation of the orthodontic appliance in the complex intraoral environment is needed.

Disclosure of Invention

In view of the above, the present invention provides an orthodontic appliance for measuring micro-deformation in real time, which can conveniently measure micro morphological changes of the appliance in different periods and under different stress conditions in an intraoral complex environment without requiring a large operation space and radioactivity, so as to estimate an internal stress condition, evaluate a treatment effect of the orthodontic appliance, and determine whether to replace or adjust the orthodontic appliance.

In order to achieve the purpose, the invention provides the following technical scheme:

an orthodontic appliance for measuring micro-deformation in real time comprises an appliance main body (1), a packaging optical fiber (2), a light wave emitter (3) and a light wave receiver (4);

the encapsulated optical fiber (2) is arranged in the appliance main body (1);

during measurement, the light wave transmitter (3) is connected with one end port of the packaging optical fiber (2), and the light wave receiver (4) is connected with the other end port of the packaging optical fiber; light waves emitted by the light wave emitter (3) are transmitted by the packaging optical fiber (2) and enter the light wave receiver (4) from the other end port, and the instant change of the internal stress and the bending of the appliance is observed by comparing the light flux amount of the appliance in the initial state and the stress state in different periods.

Further, the packaging optical fiber (2) is an optical fiber which is manufactured at the same time with the orthodontic appliance main body or is provided with a dentition shape corresponding to the orthodontic appliance main body.

Further, the encapsulated fiber (2) is embedded or made in the appliance body.

Further, the encapsulated fiber (2) is adhesively or mechanically fixed to the surface of the appliance body.

Further, the encapsulated fiber (2) is a finished network fiber, any closed or prefabricated optical path.

The invention has the beneficial effects that: the invention can measure the micro deformation in different periods and under stress state when the orthodontic appliance is in the normal use state in the mouth, and does not need to take out the appliance from the mouth to change the stress state. The device can be measured at any time, the required space is small, no radiation exists, the operation is easy, the data is easy to read, and the data change is sensitive.

Fig. 1 is a structural composition of an orthodontic appliance, which is composed of an appliance main body 1, a packaging optical fiber 2, a light wave emitter 3 and a light wave receiver 4; the encapsulated optical fiber 2 is disposed within the appliance body 1. The encapsulated optical fiber 2 in the appliance not only refers to a finished product network optical fiber in a broad sense, but also refers to any closed or prefabricated optical path, and the material and the encapsulation form of the encapsulated optical fiber can be specially made according to the required sensitivity. The emitter can emit light waves without being limited to common illumination laser, and the appropriate light wave type can be selected according to the required sensitivity.

Fig. 2 is a structure of the orthodontic appliance with optical fiber, the appearance and the basic function of the orthodontic appliance are the same as those of the common orthodontic appliance, and the optical fiber is arranged inside or outside the orthodontic appliance. The optical fiber and the orthodontic appliance are a better fixed whole, and when the orthodontic appliance deforms slightly, the curvature of the optical fiber changes accordingly.

Fig. 3 shows the basic operation principle of the orthosis of the present invention, wherein light waves are transmitted from the inlet of the encapsulated fiber 2 to the outlet of the encapsulated fiber 2 at the other end, and when the orthosis body 1 is bent, the encapsulated fiber 2 is also bent, and the curvature thereof attenuates the transmission of the light waves. The attenuation degree of the light wave is determined by measuring the transmitted light wave, and the deformation state of the current material can be basically judged according to the comparison between the measured luminous flux before and during wearing and the current instant luminous flux.

Fig. 4 is a basic scenario of the appliance of the present invention, where optical fibers are embedded in the appliance during manufacturing, or a closed optical path is directly designed in the appliance, and the optical fibers may be cemented or mechanically fixed to the outer surface of the appliance by using a strong cement material. When the material is deformed, the optical fiber is bent, and the optical wave is attenuated.

Finally, the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the claims of the present invention.
