Technical Field
[0001] The utility model relates to the technical field of myofunctional orthodontic appliances, in particular to an occlusal induction orthodontic appliance providing anterior teeth torque control. Background Art
[0002] Some children are in the habit of pressing their tongue against their teeth during the growth and development of their teeth. Doing so for a long time will cause malocclusion, that is, uneven teeth; if you are in the habit of pressing the tip of your tongue against the inside of your upper front teeth, this thrust may cause an overbite or deep overjet, that is, buck teeth; if you are in the habit of pressing the tip of your tongue between your two teeth, it may cause an open bite; if you are in the habit of pressing the tip of your tongue against the inside of your lower front teeth, it may cause an underbite, that is, an overbite or underbite.
[0003] Currently, tongue position training using oral orthodontic appliances can form muscle memory and correct the position of the tongue tip. However, during tongue position training, the upper and lower teeth need to bite the oral orthodontic appliance. Some oral orthodontic appliances are not designed properly, which can easily cause lateral pressure on the teeth and gums, affecting normal tooth development and causing labial tilt of the anterior teeth.
[0004] Therefore, it is necessary to provide an occlusal induction appliance that provides anterior teeth torque control and avoids labial inclination of anterior teeth during tongue position training. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide an occlusal induction appliance that provides anterior teeth torque control, which can avoid the lip tilt of the anterior teeth during the tongue position training process.
[0006] In order to solve the above technical problems, the utility model provides an occlusion induction appliance that provides anterior tooth torque control, comprising a main body, an upper tooth groove, a lower tooth groove and a tongue receiving groove, wherein the upper tooth groove and the lower tooth groove are arranged on opposite sides of the main body and along the outer periphery of the tongue receiving groove, the rear ends of the upper tooth groove, the lower tooth groove and the tongue receiving groove are all opened, and the angle between the tooth axis at the front end of the lower tooth groove and the horizontal direction is 90 to 105 degrees.
[0007] As an improvement to the above solution, when the tooth axis at the front end of the lower tooth groove extends from top to bottom toward the front, the angle between the tooth axis at the front end of the lower tooth groove and the vertical direction is 0 to 5 degrees.
[0008] As an improvement to the above solution, when the tooth axis at the front end of the lower tooth groove extends backward from top to bottom, the angle between the tooth axis at the front end of the lower tooth groove and the vertical direction is 0 to 15 degrees.
[0009] As an improvement of the above scheme, the front end of the lower tooth groove is provided with a first groove wall and a second groove wall, the top of the first groove wall is connected to the top of the second groove wall, the first groove wall extends from top to bottom toward the front, and the second groove wall extends from top to bottom toward the rear.
[0010] As an improvement to the above solution, on the same horizontal plane, the slope of the first groove wall is greater than the slope of the second groove wall.
[0011] As an improvement to the above solution, the angle between the tooth axis at the front end of the upper tooth groove and the horizontal direction is 95-120 degrees, and the tooth axis at the front end of the upper tooth groove extends forward from top to bottom.
[0012] As an improvement to the above scheme, the front end of the upper tooth groove is provided with a third groove wall and a fourth groove wall. The third groove wall and the fourth groove wall are both extended from bottom to top toward the rear, and the distance between the third groove wall and the fourth groove wall gradually increases from bottom to top.
[0013] As an improvement to the above solution, the third groove wall is arranged in front of the first groove wall.
[0014] As an improvement of the above solution, a breathing hole is provided at the front end of the tongue accommodating groove, and the breathing hole passes through the front end surface of the main body, and the breathing hole is not connected to the upper tooth groove and the lower tooth groove. The main body is arranged in a mirror-symmetrical manner, and a preset distance is set between the breathing hole and the symmetrical plane of the main body.
[0015] As an improvement to the above solution, on the same horizontal plane, the distance between the first groove wall and the second groove wall gradually increases from the symmetry plane to the breathing hole.
[0016] The implementation of this utility model has the following beneficial effects:

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.
[0026] like Figures 1 to 6 As shown, the utility model discloses an embodiment of an occlusal induction appliance that provides anterior tooth torque control, comprising a main body 1, an upper alveolar 2, a lower alveolar 3 and a tongue receiving groove 4, wherein the upper alveolar 2 and the lower alveolar 3 are arranged on opposite sides of the main body 1 and along the periphery of the tongue receiving groove 4, the rear ends of the upper alveolar 2, the lower alveolar 3 and the tongue receiving groove 4 are all opened, and the angle between the tooth axis a at the front end of the lower alveolar 3 and the horizontal direction is 90 to 105 degrees.
[0027] It should be noted that the upper alveoli 2 and the lower alveoli 3 on the occlusion induction appliance of this embodiment are both standard alveoli, rather than customized alveoli.
[0028] The existing occlusal induction appliance that provides torque control for anterior teeth is generally tilted backward from top to bottom for ease of wearing, and the tilt degree is relatively high, which can easily put pressure on the growing deciduous teeth or new teeth, and can easily cause the anterior teeth to tilt lip under the influence of long-term wearing; this embodiment changes the direction of the tooth axis a at the front end of the lower tooth alveolus 3, and sets the angle between the tooth axis a at the front end of the lower tooth alveolus 3 and the horizontal direction to 90~105°. The lower tooth alveolus 3 can better adapt to the normal growth direction of the lower teeth, reduce the pressure on the lower teeth and gums, and avoid the anterior teeth from tilting lip during tongue position training.
[0029] The tooth axis a at the front end of the lower tooth groove 3 in this embodiment can be set to extend from top to bottom toward the front (toward the lip side, that is, close to the lip side), or it can be set to extend from top to bottom toward the back (toward the lingual side, that is, close to the tongue side). Among them, when the tooth axis a at the front end of the lower tooth groove 3 is extended from top to bottom toward the front, the angle between the tooth axis a at the front end of the lower tooth groove and the vertical direction is 0 to 5°; when the tooth axis a at the front end of the lower tooth groove 3 is extended from top to bottom toward the back, the angle between the tooth axis a at the front end of the lower tooth groove and the vertical direction is 0 to 15°. More preferably, the tooth axis a at the front end of the lower tooth groove 3 is set to form an angle of 90° with the horizontal direction.
[0030] Specifically, the front end of the lower alveolar 3 is provided with a first alveolar wall 31 and a second alveolar wall 32 on either side of the tooth axis a. The top of the first alveolar wall 31 is connected to the top of the second alveolar wall 32. The first alveolar wall 31 extends forward from top to bottom, and the second alveolar wall 32 extends backward from top to bottom. By extending the first alveolar wall 31 forward from top to bottom and the second alveolar wall 32 backward from top to bottom, when tongue position training is performed while wearing an oral appliance of this structure, the lower alveolar 3 can better accommodate the lower teeth when biting the oral appliance, reducing lateral pressure on the lower teeth and gums, and providing a more comfortable wear.
[0031] It should be noted that the tooth axis a at the front end of the lower tooth groove 3 in this embodiment refers to the line connecting the vertex C of the lower tooth groove 3 and the midpoint D between the first groove wall 31 and the second groove wall 32 at a vertical height of 1-3 mm from the vertex C of the lower tooth groove 3 (see Figure 5 ).
[0032] For the tooth, the long axis of the tooth that represents its growth direction generally refers to the line connecting the root apex and the midpoint of the labial and palatal side of the enamel-cementum junction, or the line connecting the apex of the tooth and the apex of the root apex. It often appears in the observation and measurement of teeth and is used to describe the characteristics of teeth and the relationship between adjacent ones.
[0033] After the user wears the induction appliance for a period of time, the tooth body that is occluded at the front end of the lower alveolar 3 is affected by the first groove wall 31 and the second groove wall 32 of the lower alveolar 3, and the angle between its long axis and the tooth axis a at the front end of the lower alveolar 3 gradually decreases. Finally, the tooth body is induced by the lower alveolar 3 to grow into an ideal tooth body, and the long axis of the ideal tooth body is almost consistent with the tooth axis a at the front end of the lower alveolar 3.
[0034] Specifically, the body 1 of the present embodiment is arranged in mirror symmetry, and comprises a tongue blocking portion 11, an upper lip blocking portion 12, and a lower lip blocking portion 13. The tongue accommodating groove 4 is formed in the tongue blocking portion 11, the upper tooth groove 2 is formed between the tongue blocking portion 11 and the upper lip blocking portion 12, and the lower tooth groove 3 is formed between the tongue blocking portion 11 and the lower lip blocking portion 13. The upper lip blocking portion 12 is located outside the upper tooth groove 2, and the lower lip blocking portion 13 is located outside the lower tooth groove 3, for training the lip muscle to close and promoting the teeth to be arranged in alignment.
[0035] The first groove wall 31 is a surface of the lower lip blocking portion 13 on which the lower tooth groove 3 is formed, and the second groove wall 32 is a surface of the tongue blocking portion 11 on which the lower tooth groove 3 is formed. In the vertical direction, the first groove wall 31 and the second groove wall 32, which are arranged on opposite sides of the lower tooth groove 3, extend downwardly in directions away from each other, forming a bottom flared structure arranged downwardly.
[0036] The first groove wall 31 extends forwardly from top to bottom, and the second groove wall 32 extends rearwardly from top to bottom.
[0037] The present embodiment is provided with a breathing hole 5 in front of the tongue accommodating groove 44, for breathing and saliva circulation. The breathing hole 5 penetrates the front end surface of the body 1, and the breathing hole 5 is not communicated with the upper tooth groove 2 and the lower tooth groove 3. The breathing hole 5 is preferably arranged in the form of an elongated strip extending in the horizontal direction. The breathing hole 5 is arranged in symmetry with two, and each breathing hole 5 is provided with a predetermined distance from the symmetry plane of the body 1.
[0038] In the same horizontal plane, the slope of the first groove wall 31 is greater than the slope of the second groove wall 32.
[0039] Referring to Figure 4 In the symmetry plane, from top to bottom, the slope ɑ of the first groove wall 31 (i.e. the angle between the first groove wall 31 and the horizontal plane) gradually increases. From top to bottom, the slope β of the second groove wall 32 (i.e. the angle between the second groove wall 32 and the horizontal plane) first gradually increases, then gradually decreases, and finally gradually increases again.
[0040] By Figure 3 And Figure 6 It can be seen that, in the same horizontal plane, from the symmetry plane to the breathing hole 5, along the extension direction of the breathing hole 5 away from the symmetry plane, the distance between the first groove wall 31 and the second groove wall 32 gradually increases, so as to reserve more accommodation space for the teeth on both sides of the lower front teeth, and avoid pressing the teeth on both sides.
[0041] To avoid the formation of overbite, the tooth axis b at the front end of the upper tooth groove 2 in this embodiment is tilted at a greater angle than the tooth axis a at the front end of the lower tooth groove 3. The angle between the tooth axis b at the front end of the upper tooth groove and the horizontal direction is preferably 95-120 degrees, and the tooth axis b at the front end of the upper tooth groove 2 extends forward from top to bottom.
[0042] The front end of the upper tooth groove 2 is provided with a third groove wall 21 and a fourth groove wall 22 on both sides of the tooth axis b.
[0043] It should be noted that the tooth axis b at the front end of the upper tooth groove 2 in this embodiment refers to the line connecting the vertex E of the upper tooth groove 2 and the midpoint F between the third groove wall 21 and the fourth groove wall 22 at a vertical height of 1-4 mm from the vertex E of the upper tooth groove 2 (see Figure 5 ).
[0044] After the user wears the induction appliance for a period of time, the tooth that is occluded at the front end of the upper alveolar 2 is affected by the third alveolar wall 21 and the fourth alveolar wall 22 of the upper alveolar 2, and the angle between its long axis and the tooth axis b at the front end of the upper alveolar 2 gradually decreases. Finally, the tooth is induced by the upper alveolar 2 to grow into an ideal tooth, and the long axis of the ideal tooth is almost consistent with the tooth axis b at the front end of the upper alveolar 2.
[0045] Among them, the third groove wall 21 is the surface of the upper lip retaining portion 12 forming the upper tooth groove 2; the fourth groove wall 22 is the surface of the tongue crotch portion 11 forming the upper tooth groove 2. The third groove wall 21 and the fourth groove wall 22 are both extended from bottom to top toward the rear, and the distance between the third groove wall 21 and the fourth groove wall 22 gradually increases from bottom to top, forming a top flared structure inclined toward the rear. In this embodiment, the top of the front end of the lower tooth groove 3 is located behind the bottom of the front end of the upper tooth groove 2, and the third groove wall 21 is located in front of the first groove wall 31 to confine the lower teeth behind the upper teeth, avoiding the occurrence of overbite during tongue position training.
[0046] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
