[0024] To make the purpose, technical scheme and advantage of the utility model more clear, the utility model will be further described in detail below with the drawings.

[0025] As Figure 1 and Figure 2 shown, the utility model discloses a kind of appliance for assisting to maintain interdental gap of the first embodiment, including jaw pad 1, upper tooth groove a and lower tooth groove b oppositely arranged in the both sides of jaw pad 1;At least one of the upper tooth groove a and the lower tooth groove b is provided with gap maintaining part A, the gap maintaining part A includes the first protrusion 11 extended by the jaw pad 1 to distal end, the first protrusion 11 is used to abut with the tooth side of the rear side of interdental gap, and the first protrusion 11 and the tooth of the front side of interdental gap maintain first preset distance.

[0026] In this embodiment, a gap-maintaining part A is provided in at least one of the upper alveolar ridge a and the lower alveolar ridge b. The first protrusion 11 of the gap-maintaining part A is formed on the jaw pad 1. When worn, the first protrusion 11 abuts against the tooth side of the interdental space behind the tooth and maintains a first preset distance from the tooth of the interdental space in front of the tooth. On the one hand, the first protrusion 11 can prevent the tooth of the interdental space behind the tooth from growing forward and occupying space. On the other hand, the first protrusion 11 maintains a first preset distance from the tooth of the interdental space in front of the tooth, which reduces the resistance to the eruption of the permanent tooth in the interdental space behind the tooth and facilitates the rapid eruption of the permanent tooth.

[0027] It should be noted that, due to the influence of tooth growth patterns and chewing habits, when interdental spaces appear on the lateral side of the oral cavity, teeth growing behind the interdental space tend to grow forward and occupy space, while teeth growing in front of the interdental space are less likely to grow backward and occupy space. When an interdental space appears on the side of the oral cavity, the first protrusion 11 in this embodiment can effectively prevent teeth behind the interdental space from growing forward and occupying space.

[0028] When interdental spaces occur at the front of the mouth, i.e., in the position of the front teeth, the difference in force between the teeth on both sides of the interdental space is relatively small. To avoid the teeth on both sides of the interdental space occupying space, it is necessary to combine... Figure 3 In the second embodiment, a second protrusion 12 extending distally from the occlusal pad and a clearance groove 13 located between the first protrusion 11 and the second protrusion 12 are provided in the gap-maintaining part. The first protrusion 11 and the second protrusion 12 are arranged along the extending direction of the upper alveolar bone a or the lower alveolar bone b. The first protrusion 11 and the second protrusion 12 are both located in positions such as deciduous tooth loss, missing teeth, or primate gaps, i.e., between two teeth where a gap needs to be maintained. The first protrusion 11 and the second protrusion 12 respectively prevent adjacent teeth from occupying the clearance groove 13 and stably maintain the interdental gap. At the same time, the clearance groove 13 between the first protrusion 11 and the second protrusion 12 provides growth space for the eruption of permanent teeth. Compared with a gap-maintaining structure that occupies the entire gap between two teeth, the gap-maintaining part A of this embodiment provides less resistance to the eruption of permanent teeth and is more conducive to the rapid eruption of permanent teeth.

[0029] Specifically, the appliance of the embodiment further comprises a tongue barrier 2 formed on the inner side of the jaw pad 1, a lower lip barrier 3 formed by extending downward from the outer side of the jaw pad 1, and an upper lip barrier 4 formed by extending downward from the outer side of the jaw pad 1. The tongue barrier 2, the jaw pad 1, and the lower lip barrier 3 form the lower tooth groove b, and the tongue barrier 2, the jaw pad 1, and the upper lip barrier 4 form the upper tooth groove a. The jaw pad 1, the tongue barrier 2, the upper lip barrier 4, the lower lip barrier 3, and the first protrusion 11 of the appliance of the embodiment are integrally formed by using a silicone material. The top surface and the bottom surface of the jaw pad 1 can be flat or curved to match the end surface of the teeth. The lower lip barrier 3 covers the outer side of the lower teeth, the upper lip barrier 4 covers the outer side of the upper teeth, and the tongue barrier 2 covers the inner side of the upper and lower teeth. The tongue barrier 2 is provided with a breathing hole 6, and the breathing hole 6 penetrates at least one of the upper lip barrier 4 and the lower lip barrier 3 to help the wearer to breathe smoothly. The appliance can be continuously worn by the wearer at night to maintain the interdental space and help the permanent teeth to erupt and grow smoothly.

[0030] The fourth protrusion 111 of the first protrusion 11 and the fifth protrusion 121 of the second protrusion 12 are provided with a fourth predetermined distance and a fifth predetermined distance from the opening edge of the upper tooth groove a or the lower tooth groove b, respectively, to avoid the first protrusion 11 and the second protrusion 12 from sticking to the gums and causing discomfort, and to avoid pressing the unerupted permanent teeth during the replacement tooth period. Generally, when the first protrusion 11 and the second protrusion 12 are formed in the lower tooth groove b, the height of the first protrusion 11 and the second protrusion 12 is 1 / 4-3 / 2 of the distance from the bottom surface of the jaw pad 1 to the bottom of the lower lip barrier 3, and when the first protrusion 11 and the second protrusion 12 are formed in the upper tooth groove a, the height of the first protrusion 11 and the second protrusion 12 is 1 / 4-3 / 2 of the distance from the top surface of the jaw pad 1 to the top of the upper lip barrier 4. To improve the stability of the structure of the first protrusion 11 and the second protrusion 12, the first protrusion 11 and the second protrusion 12 are connected to the tongue barrier 2, and the first protrusion 11 and the second protrusion 12 are connected to the upper lip barrier 4 or the lower lip barrier 3.

[0031] In combination with Figure 4 In the third embodiment, the first protrusion 11 is provided with a third protrusion 111 protruding away from the avoidance groove 13, and the second protrusion 12 is provided with a fourth protrusion 121 protruding away from the avoidance groove. The third protrusion 111 provides elastic pressure to the teeth opposite to it to avoid the end surface of the teeth from tilting and occupying the interdental space, and the fourth protrusion 121 also provides elastic pressure to the teeth opposite to it to avoid the end surface of the teeth from tilting and occupying the interdental space. The cross-sectional shape of the third protrusion 111 and the fourth protrusion 121 can be triangular, square, trapezoidal, or circular.

[0032] The avoidance groove 13 is provided with a first groove wall located at the first protrusion 11 and a second groove wall located at the second protrusion 12. The first groove wall and the second groove wall are oppositely arranged, and the distance between the first groove wall and the second groove wall gradually increases in the direction away from the jaw pad 1, that is, the avoidance groove 13 is outwardly expanded towards the distal end of the jaw pad 1, so as to reduce the resistance of the first protrusion 11 and the second protrusion 12 to the newly erupted permanent tooth.

[0033] In addition, the end surface of the first protrusion 11 away from the jaw pad 1 is at a first preset angle with the first groove wall, and the end surface of the second protrusion 12 away from the jaw pad is at a second preset angle with the second groove wall. The first preset angle and the second preset angle of the present embodiment are both a, which is an acute angle, preferably less than 45°, so as to form a sharp angle, so that the end surface of the first protrusion 11 does not abut on the newly erupted permanent tooth. At the same time, the end surface of the first protrusion 11 and the end surface of the second protrusion 12 form a half arrow shape. When occlusion, the end surface of the first protrusion 11 and the end surface of the second protrusion 12 respectively provide pressure to the tooth inclinedly occupying the interdental space, and the greater the reverse pressure on the tooth inclinedly occupying the interdental space, the more help to correct the tooth inclinedly occupying the interdental space, and to open up the growth space for the newly erupted permanent tooth. In addition, the end surface of the first protrusion 11 and the end surface of the second protrusion 12 can also form other three-dimensional shapes, such as pyramidal, spherical, columnar, etc.

[0034] In combination with Figure 5 The fourth embodiment is given to improve the strength of the first protrusion 11 and the second protrusion 12. The cross section of the first protrusion 11 and the second protrusion 12 of the present embodiment gradually increases in the direction close to the jaw pad 1. The thickness dimension of the first protrusion 11 and the second protrusion along the extension direction of the upper dental groove a or the lower dental groove b is 1-6 mm.

[0035] In combination with Figure 6The fifth embodiment is provided with the fifth protrusion 14 and the sixth protrusion 15 on the jaw pad 1, the fifth protrusion 14 is arranged on the opposite side of the first protrusion 11 with the avoidance slot 13, the fifth protrusion 14 is connected with the first protrusion 11, and the second preset distance is arranged between the end of the fifth protrusion 14 and the first protrusion 11. The sixth protrusion 15 is arranged on the opposite side of the second protrusion 12 with the avoidance slot 13, the sixth protrusion 15 is connected with the second protrusion 12, and the third preset distance is arranged between the end of the sixth protrusion 15 and the second protrusion 12. The first protrusion 11 and the second protrusion 12 respectively play the role of preventing the adjacent teeth from occupying the avoidance slot 13 and stably maintaining the interdental space, and the avoidance slot 13 between the first protrusion 11 and the second protrusion 12 provides the growth space for the permanent tooth eruption. Compared with the gap maintaining structure occupying the entire gap between two teeth, the gap maintaining part A of the embodiment has smaller resistance to the permanent tooth eruption, and is more conducive to the rapid eruption of the permanent tooth. In addition, since the fifth protrusion 14 and the sixth protrusion 15 protrude to the surface of the jaw pad 1, when the patient wears the occlusion appliance, the end surface of the two teeth that need to maintain the gap will be subjected to the pressure action of the fifth protrusion 14 and the sixth protrusion 15. Compared with other teeth, the end surface of the two teeth adjacent to the interdental space is subjected to greater pressure than the end surface of other teeth due to the arrangement of the fifth protrusion 14 and the sixth protrusion 15, which further helps to inhibit the growth of the teeth on both sides of the interdental space in the direction close to the gap. The two teeth adjacent to the interdental space are respectively subjected to the compression of the first protrusion 11 and the fifth protrusion 14 and the compression of the second protrusion 12 and the sixth protrusion 15, which better helps to inhibit the growth of the teeth on both sides of the interdental space in the direction close to the interdental space, and avoids the inclination of the end surface of the tooth to the interdental space.

[0036] The above only discloses a preferred embodiment of the utility model, of course, cannot limit the scope of the utility model, therefore, the equivalent changes made according to the utility model claim still belong to the range covered by the utility model.
