Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an orthodontic device capable of returning the displacement of the temporomandibular joint to a normal position by keeping the upper and lower occlusal teeth in a normal occlusal state and customizing them. Is.

[0002]

BACKGROUND OF THE INVENTION and Prior Art The human jaw is a portion that surrounds the oral cavity from above and below and is divided into an upper jaw and a lower jaw. There are upper and lower jawbones and mandibles in the upper and lower parts of the jaw, respectively, to form columns, and teeth are planted in these upper and lower jawbones. The mandible is tied to the skull by the temporomandibular joint, and moves in the anterior, posterior, and lateral directions with respect to the maxilla, chewing food, and performing a predetermined motion during conversation.

Since the temporomandibular joint controls 68 pairs of muscles and some of them also affect the cranial nerves, the temporomandibular joint must always be held so as not to be displaced.

However, when the occlusal state of the upper and lower teeth is displaced (so-called malocclusion), the position of the temporomandibular joint is also deviated, and for example, when the mandible is pushed inward, the head is correspondingly moved. As the body leans forward, the body tries to make the muscles behind the neck pull the heavy head toward the front to adjust it, but as a result, the muscles of the neck continue to be tense and the neck muscles become stiff. I have stiff shoulders. Then, while forcing this unreasonable muscle tension, the bones of the neck are distorted, the position of the head is displaced, and the head leans to the left or right.

Furthermore, when the neck distortion spreads from the spine to the whole body and the heavy head is tilted, the position of the body supporting it is displaced, and as a result, the spine is bent. This spine protects nerves connected to each organ, organ, and muscle, and many nerves are output from between the vertebral bodies constituting the spine, and are connected to each organ, organ, and muscle. The fact that the spine is curved means that the connection of each vertebral body is displaced, and the nerves coming out of the displaced vertebral bodies are compressed, affecting each of the organs, organs and muscles, resulting in headache. In addition to causing tinnitus, facial neuralgia, shoulder pain, neck pain, back pain, and spinal curvature, it also caused visceral disease.

However, there has been no device for correcting the displacement of the temporomandibular joint. Certainly, there has been an orthodontic braces in the past, but this is a device that restores the misalignment of the teeth to the normal position, and does not have the action and effect of returning the displacement of the temporomandibular joint to the normal position.

[0007]

In view of the problem that the malocclusion of the teeth causes the displacement of the temporomandibular joint, and various symptoms occur in the living body as a result, the present inventors have found that the maxillary bone and the mandible The present invention has been made paying attention to the fact that the position of the temporomandibular joint is not displaced if the occlusal state of the teeth is held in the normal position.

[0008]

SUMMARY OF THE INVENTION The present invention uses a flexible material such as latex rubber, silicone rubber, or medical grade PVC to make a base in an arcuate or U-shaped planar shape to match the arrangement shape of human jaw and teeth. Forming a portion, and the base portion comprises an outer flange portion along its outer edge portion and an inner flange portion along its inner edge portion, said base portion adjoining the rearward end Has a maximum thickness, and has a taper that gradually decreases from the rearward portion toward the center of the tip portion, and the outer and inner flange portions have an upper portion for receiving teeth together with the base portion. And a lower passage, each of which is formed such that its width gradually increases from the center of the tip to the rear end so as to match the shape of the tooth contact surface. Serial outer and inner flange portion,
At that height, the taper is gradually reduced from the central tip toward the rear end, and the outer flange portion is gently curved inward with a maximum inclination angle at the central tip portion. While the inclination angle gradually decreases from the central tip toward the rear end and the curved surface becomes shallower, the inner flange portion is a deep curve curved inward at the maximum inclination angle at the central tip portion. A curved recess having a surface, the inclination angle of which gradually decreases toward the rear end from the central tip, and the curved surface of which gradually becomes shallower, is formed to be a substantially vertical surface in the vicinity of the rear end. The above-mentioned problems are solved by adopting the means.

[0009]

According to the present invention having the above-mentioned structure, the device for correcting the displacement of the temporomandibular joint of the present invention is installed in the oral cavity, and the device is simply worn for about 1 hour or for several minutes depending on the symptom. By moving the mandible up and down or by mounting it all day long, the occlusal state of the upper and lower teeth returns to the normal position, the displacement of the temporomandibular joint is eliminated, and the normal balance is maintained.
