At this time, the lower clasp 220 is installed to be symmetrical with respect to the median plane (MP, Median plane) of the patient, as shown in Figure 4, which is the greatest feature of the present invention, When both ends are fixed and the mandible is towed forward, the mandible can be pulled with equal force and the mandible is turned forward so that it is not twisted laterally to maintain the balance of the jaw joint. As a result, it is possible to minimize damage to the jaw joint and the related muscles constituting the jaw joint. In addition, as shown in the enlarged view of FIG. 6, the fixture 240 is formed at a predetermined depth through the front inside of the mandible 200, and the bottleneck device 400, which will be described later, is screwed to the fixture 240. Threads are formed to engage.

Next, the elastic part 300 is integrally fixed to the front outer side of the upper jaw portion 100 and both ends are fixed to both the front inner wall surface of the mandible 200, through a bottleneck device 400 to be described later Both paths of the elastic part 300 are merged with each other. More specifically, the elastic part 300 may be basically used to have a rubber band having elasticity, in some cases can be produced by using a synthetic resin or nylon string. In addition, in order to control the amount of protrusion of the mandible may be used by adjusting the elastic modulus of the elastic portion 300. In addition, both ends of the elastic portion 300 is provided with a fixing ring 310, the fixing ring 310 is configured to be supported by the lower clasp 220 is attached to the lower mandrel (200). At this time, the fixing ring 310 may be implemented through various embodiments that may be caught on the lower clasp 220 and at the same time, the fastening method of the fixing ring 310 and the lower clasp 220 may also be modified in various forms. Let's find out. More specifically, the elastic part 300 is simultaneously fixed to the front outer side of the upper jaw portion 100 and the front inner side of the lower jaw portion 200 to pull the lower portion 200 forward by the tension. That is, both ends of the elastic part 300 are fixed to the mandible 200 by fastening the fixing ring 310 and the lower clasp 220, and at the same time, the path of the elastic part 300 is placed on the upper part 100. The upper clasp 120 is configured to be supported by the latch. That is, the lower part 200 is guided forward by the tension of the elastic part 300 connecting between the upper part 100 and the lower part 200. The detailed operation of the elastic portion 300 will be described later.

Next, the bottleneck device 400 is installed inside the front of the mandible 200 so that the elastic portion 300 can be connected. More specifically, the bottleneck device 400 is located on the path of the median surface (MP), as shown in Figure 4 is inserted into the fixture 240 formed in the lower jaw (200). At this time, in the present embodiment will be described an example in which the bottleneck device 400 is screwed to the fixture 240, but is not limited to this, it will be clear that it can be configured through various coupling relationships. At this time, the bottleneck device 400 is composed of a ring-shaped merge ring 410 and a control shaft 420 vertically protruding from the bottom of the merge ring 410, as shown in Figure 5, the control shaft ( The thread 420 is formed to be screwed with the fixture 240. That is, as shown in Figures 2 to 4, both ends of the elastic portion 300 fixed to the lower mandrel 200 is passed through the merge ring 410 is caught by the upper clasp 120 of the upper jaw portion 100 When the mandible 200 is pulled forward, the force to be pulled forward converges in the direction of the median plane MP to act in one direction. Therefore, the elastic part 300 may utilize three points of the mandible 200 as a support point, thereby preventing the eccentric force from being applied to the rear of the mandible 200 during the forward traction of the mandible 200. . As a result, it is possible to prevent the jaw joint from twisting laterally when pulling the mandible forward. In addition, as shown in FIG. 6, the bottleneck device 400 may adjust the tension of the elastic part 300 passing through the merge ring 410 by adjusting the depth inserted into the fixture 240. For example, when minimizing the depth of the control shaft 420 inserted into the fixture 240, the elastic portion 300 can be pulled more tightly so as to maximize the amount that can advance the mandible 200 do. That is, since the adjustment shaft 420 is screwed in the fixture 240, the control shaft 420 is inserted into the fixture 240 by adjusting the rotational speed of the adjustment shaft 420 inserted into the fixture 240. The depth can be adjusted.

Next, as shown in FIG. 11, the lower jaw portion 200 may further include an insertion passage 230 through which an inner side thereof is passed to accommodate the elastic portion 300. More specifically, the insertion passage 230 is a tubular shape formed to be inserted in the longitudinal direction of the elastic portion 300 as a lighter means for minimizing contact of the elastic portion 300 to the tongue. That is, through the elastic portion 300 inserted into the insertion passage 230, the patient can minimize the feeling of the elastic portion 300 sensed on the tongue, thereby reducing the foreign body feeling.

Next, another embodiment of the bottleneck device in the first embodiment according to the present invention will be described.
