Description

Mandible displacement adjusting device

The invention relates to a mandibular displacement adjustment device, in particular to a mandibular displacement adjustment device capable of positioning the mandible of the human body forward to keep the breathing passage unobstructed, and at the same time solving the problems of stopping breathing and snoring during sleep.

There are many people who snore and stop breathing during sleep. This is mainly because the muscles relax during sleep, and due to the relationship of gravity, as shown in Figure 1, the support of the oral cavity 101 inside the mouth 10 will be soft. The muscles of the jaw 102 and the base of the tongue 7 fall down so that the breathing passage 8 is squeezed so that the air cannot be kept unblocked, so snoring will occur, and even severely, it will cause apnea or panting, so it is also called It is sleep apnea, and sleep apnea may affect the quality of sleep, and may even induce hypertension, heart disease and other symptoms.

In order to solve the above problems, there are many so-called anti-snoring devices or anti-snoring devices on the market. Most of the existing anti-snoring devices use upper and lower braces and combine with a connecting mechanism to move the mandible forward. , To prevent the jaw from drooping and blocking the breathing channel 8.

However, the above-mentioned conventional products all use a fixing mechanism to fix the upper and lower braces. Because the mandible is forced to move forward and fixed forcibly, the mandible cannot move back. However, if worn for a long time, it will As a result, the mandibular condyle is extremely sore, so the user will not be able to adapt to wearing this device, so it will be very troublesome for users with respiratory arrest symptoms.

In addition, since most of the existing anti-snoring devices are customized The shape does not match, so that there are gaps between the braces and the teeth, so there is a situation that the position is shifted or even falls off, so it will cause the poor effect of stopping snoring and avoiding respiratory arrest.

In addition, because the existing anti-snoring device is worn around the two rows of dentitions of the upper and lower jaw with braces, the braces will have a certain thickness. Once the mandible is moved forward, the thickness of the upper and lower braces will make The occlusion of the front teeth produces a significant foreign body sensation. If the user wears this device while sleeping, it will also make it difficult to fall asleep easily.

In addition, there is currently another anti-snoring device, which is to install the connecting mechanism at the incisor area, that is, by pulling the upper and lower incisor pull buckles to force the mandible to move forward, but this setting will force the incisor area If it is too large, the incisor area will be extremely uncomfortable for the user after being worn for a long time. Therefore, this is not a device type that can be used for a long time.

Therefore, in order to solve the above-mentioned problems, the present invention is equipped with a first positioning part and a second positioning part at the upper and lower braces, and an extension section and hook part are extended from the upper and second positioning parts. After the hooks of the second positioning part are engaged, the mandible can be placed in the forward position to keep the breathing passage 8 unobstructed, and at the same time solve the problem of breathing interruption and snoring; in addition, because the upper and second positioning parts are not tightly matched , It is a movable engagement.

Other technical content, features and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiment with reference to the drawings.

As shown in Figure 2, the human oral cavity has upper and lower dental arches, and the dentition of the upper and lower dental arches is as follows:

1. The dental arch of the upper mandible has the following dentitions: (a) the anterior area 31, which contains the upper orthodontic incisors 311, the upper incisors 312, and the upper canine teeth 313; (b) the upper molar area 32, which contains the first molars 321, the second molar 322, the first molar 323, the second molar 324 (and the third molar).

2. The dental arch of the mandible has the following dentitions: (a) Anterior teeth area 41, which includes lower front teeth 411, lower incisor teeth 412, and lower canine teeth 413; (b) Lower molar area 42, which includes the first small Molars 421, second molars 422, first molars 423, second molars 424 (and third molars).

As shown in Figures 3A, 3B, 4A, and 4B, the mandibular displacement adjustment device of the present invention includes an upper dental set 1 and a lower dental set 2. Because the upper dental set 1 and the lower dental set 2 each have an upper dental The accommodating space 11 and the lower tooth accommodating space 21, and because the upper dental kit 1 and the lower dental kit 2 are made by 3D scanning the user's teeth, the upper and lower dental arches of the human body will be in line with each other. The upper tooth accommodating space 11 and the lower tooth accommodating space 21 are in close contact; A first positioning portion 12 is provided on the side wall of the upper dental kit 1 corresponding to the upper molar area 32. The first positioning portion 12 includes a first extension section 121 extending toward the lower molar area 42, and the front end of the first extension section 121 Bending toward the anterior tooth region 41 to form a first hook 122; A second positioning portion 22 is provided on the side wall of the lower dental kit 2 corresponding to the lower molar area 32. The second positioning portion 22 extends toward the upper molar area 32 to extend a second extension 221, and the front end of the second extension 221 A second hook 222 is bent and extended toward the condyle 51 of the mandible 5; The first positioning portion 12 and the second positioning portion 22 are a C-shaped structure or an L-shaped structure that can be movably engaged. Therefore, when wearing the upper dental kit 1 and the lower dental kit 2 (mandibular 5 After the condyle 51 is in the original position A1), the user must control the mandible 5 to move down through the mouth muscles, and then move the mandible 5 forward to drive the lower teeth set 2 to move forward, and then close the mouth. As shown in Figure 5, the second hook portion 222 will naturally hook back on the first hook portion 122 (the condyle 51 moves to the forward position A2, and the state of engagement is shown in Figure 6) However, in this embodiment, the first positioning portion 12 and the second positioning portion 22 are both disposed at one side corresponding to the periphery of the first molar. When the first hook portion 122 and the second hook portion 222 are hooked, the first extension section 121 is mainly used to block the second extension section 221 from moving backward, so as to position the mandible 5 at a preset front The position can be customized for the user. Take a forward position that is acceptable for the user’s physiology. It will not cause discomfort due to too much displacement. The displacement of the mandible 5 depends on the The first positioning portion 12 is arranged at the position of the upper molar region 32. When the second extension section 221 is blocked by the first extension section 121, it can prevent the mandible 5 from moving back to the initial position; in addition, the first hook The portion 122 mainly blocks the second hook portion 222 from moving down, so that the mandible 5 cannot move downwards, so as to prevent the user from opening his mouth during sleep; therefore, when the mandible 5 moves forward, it is positioned and cannot move down. When the mouth is opened, the base of the tongue 7 and the supporting soft palate 102 can be pulled upward to keep the breathing channel 8 unblocked during sleep and avoid apnea and snoring.

In addition, as shown in Fig. 8, the upper dental set 1 or/and the lower dental set 2 are provided with an opening 13, 23 relative to the anterior teeth regions 31, 41 of the human upper jaw dental arch 3 and the human lower dental arch 4, It is used to expose the tooth surfaces of the anterior teeth areas 31 and 41, so that when the user's lower jaw 5 moves forward, the tooth surfaces of the anterior teeth areas 31 and 41 can contact each other without being affected by the upper teeth set 1 or/and The thickness of the mandible set 2 is too thick, which causes the mandible 5 to be in the lower position, which causes discomfort at the condyle 51.

In addition, in order to avoid the user’s bite discomfort due to the thickness of the upper dental kit 1 or/and the lower dental kit 2, the upper dental kit and the lower dental kit can be compared with the human upper dental arch and the human lower dental kit. The thickness of the occlusal surface of the anterior region of the arch is designed to be less than 1mm, so that the occlusion of the anterior region can be as similar as possible to the occlusal habits before wearing the braces, so as to reduce the user's discomfort.

In addition, the first extension section 121 of the first positioning portion 12 and the second extension section 221 of the second positioning portion 22 extend obliquely at 35-55 degrees, of which an angle of 45 degrees is the best.

Please refer to Figure 7, Figure 9, and Figure 10A-C, in which, in order to avoid the position of the mandible 5 advanced positioning can not keep the breathing channel unobstructed during sleep, the first extension 121 or the second extension can be used An adjuster 6 (as shown in FIG. 9) is attached to the segment 221 as required. The thickness of the adjuster 6 can control the position where the mandible 5 moves forward. As shown in Fig. 10A-C, the adjuster 6, 6', 6" is flexible and has a hole 61, 61', 61". The design of the adjuster is through the design of the hole 61, 61', 61". 6,6',6" is sleeved on the first extension section 121 or the second extension section 221, and the adjuster 6,6',6" can be designed with different thicknesses for the user to choose The required adjuster 6, 6', 6” can be used to adjust the position of the mandible 5 forward to achieve the purpose of fine adjustment. At the same time, the breathing channel 8 is maintained at the forward position acceptable to the user. The smooth flow, avoiding the termination of breathing during sleep and achieving the purpose of stopping snoring.

The advantages of the lower jaw displacement adjusting device provided by the present invention when compared with other conventional technologies are as follows:

(1) When the human body sleeps, the mandible 5 will move freely. If the mandible 5 is fixed, after a long period of time, the A1 of the condyle 51 of the mandible 5 will definitely have a great sense of discomfort, and the present invention The first positioning portion 12 and the second positioning portion 22 are both C-shaped or L-shaped, so that the inner space of the first extension 121 and the first hook portion 122 of the first positioning portion 12 forms an omnidirectional activity space 9. The second extension section 221 of the second positioning portion 22 and the second hook portion 222 can move freely in the omnidirectional movement space 9, so that the mandible 5 can move freely in all directions when the user sleeps When worn for a long time, the condyle 51 of the mandible 5 will not produce any discomfort.

(2) When the present invention positions the mandible 5 forward, the tongue base 7 and the supporting soft jaw 102 will be simultaneously pulled upward to keep the breathing passage 8 unblocked, so as to solve the problem of the user's breathing interruption and snoring during sleep.
