Description

Technical Field

[0001] The utility model relates to the field of oral orthodontics, in particular to an orthodontic positioner. Background Art

[0002] In fixed orthodontic treatment, the accuracy of bracket positioning and bonding plays a vital role. Usually, doctors will directly bond the bracket to the tooth surface based on their personal clinical experience and visual judgment, and apply positioning principles such as the clinical crown center method. In traditional bracket bonding methods, the bonding time and bonding accuracy of the bracket will be directly affected by the operating doctor's clinical experience, that is, whether the bracket is accurately pasted on the tooth surface is largely affected by the doctor's clinical experience. In addition, the intraoral field of vision in the posterior tooth area is limited, and the teeth cannot be observed vertically on the tooth surface, resulting in positioning errors and affecting the installation effect of the bracket.

[0003] At present, most bracket locators with hydrosol fixation method are used clinically to bond the brackets to the tooth surface. However, the amount of hydrosol applied cannot be accurately controlled. If there is too little hydrosol, the bracket is easy to fall off from the locator during transportation, and the bracket cannot be firmly installed on the tooth surface, affecting the orthodontic treatment of the teeth. If there is too much hydrosol, when removing the locator, it is difficult to remove the locator because some of the hydrosol has not been completely dissolved. The locator is difficult to remove from the bracket and the bracket cannot be used normally.

[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application aims to provide an orthodontic positioner, aiming to solve the problem in the prior art that brackets cannot be accurately installed on teeth.

[0034] The utility model provides an orthodontic positioner. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] like Figures 1 to 8 As shown, the present application includes an orthodontic positioner for assisting the installation of brackets, so that the brackets can be accurately installed on the tooth surface of the teeth, and then the brackets can start orthodontic treatment of the teeth. Specifically, in the present application, the orthodontic positioner includes a clamping portion 1, a nesting portion 2 and an identification portion 3. The clamping portion 1 is clamped on the bracket, and then the orthodontic positioner is fixed on the bracket, and the auxiliary bracket is pasted on the tooth surface. At the same time, an overflow channel for the overflow of the resin adhesive is reserved in the clamping portion 1 to avoid the situation where the orthodontic positioner is too much and it is difficult to remove the orthodontic positioner, affecting the subsequent use of the bracket; the nesting portion 2 is nested on the tooth, that is, when the bracket is installed on the tooth surface of the tooth through the orthodontic positioner, the nesting portion 2 is nested on the tooth at this time, so as to assist the installation of the bracket and avoid the bracket installation When installed on the tooth surface of the tooth, it deviates from the position, and the clamping part 1 is installed on one side of the nesting part 2, so that when the nesting part 2 is embedded in the tooth, the clamping part 1 can be clamped on the bracket, and the bracket is installed on the tooth surface of the tooth. The position of the bracket installed on the tooth surface is locked by allowing the nesting part 2 to be nested on the tooth, thereby avoiding the installation position of the bracket to be offset and affect the orthodontic effect of the tooth, or even cause orthodontic failure of the tooth; the identification part 3 is installed on the other side of the nesting part 2, and is used to identify the installation position of the orthodontic locator. Different identifications indicate that the orthodontic locator is installed on the bracket on the tooth surface of different teeth.

[0036] Furthermore, in order to enable the clamping part 1 to clamp the bracket, the clamping part 1 includes a clamping groove 11, and the clamping part 1 clamps the bracket through the clamping groove 11. Figures 5 to 8As shown, the clamping groove 11 is elliptical as a whole, and the outer circle of the clamping groove 11 is smooth and has no edges and corners, so as to prevent the orthodontic locator from scratching the inner wall of the patient's mouth when the clamping part 1 is clamped on the bracket, and the clamping groove 11 is a U-shaped semi-wrapped structure, which can make the clamping groove 11 and the bracket fit completely, which is conducive to the clamping groove 11 clamping the bracket, and at the same time, a cavity is formed in the middle of the clamping groove 11, and the cavity and the bracket have an interference fit, so as to prevent the clamping groove 11 from detaching from the bracket, so that the clamping groove 11 can be fixed on the bracket until the orthodontic locator needs to be removed from the bracket, and then the clamping part 1 is shaken to separate the clamping groove 11 from the bracket.

[0037] In the prior art, the bracket is fixed to the tooth surface by a resin adhesive. Specifically, the resin adhesive is applied to the position where the bracket contacts the tooth surface, the bracket is attached to the tooth surface, and then the resin adhesive is hardened by light curing, so that the bracket is adhered and fixed to the tooth surface. When too much resin adhesive is applied, the resin adhesive will flow into the gap between the bracket and the locator. During light curing, the resin adhesive between the bracket and the locator will also harden, so that the bracket and the locator are bonded together, making it difficult to remove the locator from the bracket, affecting the use of the bracket. Therefore, in order to discharge excess resin adhesive in time and prevent excess resin adhesive from affecting the removal of the locator, the clamping portion 1 also includes a plurality of overflow holes 12, through which excess resin adhesive is discharged in time. In this embodiment, two overflow holes 12 are provided. Figures 5 to 8 As shown, the overflow holes 12 are arranged at the top of both sides of the clamping groove 11, and the overflow holes 12 are semicircular. The overflow holes 12 are smoothly transitioned at one end away from the bracket, so that the excess resin adhesive can flow out smoothly, and the excess resin adhesive is prevented from flowing into the gap between the bracket and the orthodontic locator. Therefore, when the clamping groove 11 is clamped on the bracket, an overflow hole 12 is arranged between the clamping groove 11 and the bracket, so when the resin adhesive is applied on the bracket and the clamping groove 11 is clamped on the bracket, if the applied resin adhesive is large, the excess resin adhesive can flow out from the overflow hole 12 between the clamping groove 11 and the bracket in time, avoiding the situation that the orthodontic locator is difficult to remove due to part of the resin adhesive flowing into the gap between the bracket and the locator, thereby enabling the orthodontic locator to be removed normally and in time, so that the bracket can be put into use in time.

[0038] At the same time, in the prior art, in order to prevent the bracket from falling out of the locator when the locator is attaching the bracket to the tooth surface of the tooth, it is necessary to fix the bracket in the locator during the process of attaching the bracket to the tooth surface to prevent the bracket from falling out of the locator. After the bracket is fixed on the tooth surface of the tooth, the locator and the bracket must be separated in time and the locator must be removed from the bracket so that the bracket can be used normally. Therefore, in the prior art, by applying hydrosol on the contact surface between the bracket and the locator, the bracket can be fixed on the locator when placed in the locator. At the same time, after completing the operation of installing the bracket on the tooth surface of the tooth, the gap between the bracket and the locator is rinsed with water, so that the hydrosol between the bracket and the locator can be dissolved, and the locator is no longer attached to the bracket. At this time, the locator can be removed from the bracket. When too much hydrosol is applied, the hydrosol will penetrate into the deeper part of the locator. Although it is in contact with the bracket here and the bracket can be fixed by the hydrosol, when the locator needs to be removed from the bracket for flushing, the flushing water flow cannot enter the deeper part of the locator. This also means that the hydrosol between the deep part of the locator and the bracket cannot be dissolved, and the locator and the bracket continue to remain adhered, resulting in the locator and the bracket still cannot be separated normally after flushing, affecting the use of the bracket. Therefore, in order to avoid the above situation, in the present application, hydrosol is no longer used to fix the bracket in the orthodontic locator. Instead, a specific structure is provided in the orthodontic locator so that the bracket can be detachably installed in the orthodontic locator. Specifically, in order to allow the bracket to be fixed in position when clamped by the clamping groove 11, thereby limiting the bracket from rotating and falling off the locator, the clamping portion 1 also includes a square buckle 13. In the present embodiment, two square buckles 13 are provided. The two square buckles 13 are respectively provided on the inner walls on both sides of the clamping groove 11, such as Figures 5 to 8As shown, two square clips 13 are respectively arranged at the middle position of the inner walls on both sides of the clamping groove 11, corresponding to the grooves of the bracket, and connected with the grooves of the bracket in a concave-convex combination to limit the up and down movement of the bracket after being embedded in the orthodontic positioner. At the same time, the two square clips 13 are symmetrical along the central axis of the orthodontic positioner, and the other two square clips 13 are respectively protruded from the inner walls on both sides of the clamping groove 11, and the protruding thickness of the two square clips 13 is the same. In this way, when the square clips 13 are embedded in the grooves of the bracket, the embedded positions of the square clips 13 are also symmetrical along the central axis of the bracket, and the embedded depths of the two square clips 13 are also the same, so as to prevent the two square clips 13 from being unable to be stably fixed in the orthodontic positioner due to the different embedded depths, but rotating in the orthodontic positioner, thereby affecting the accuracy of the bracket installed on the tooth surface. In addition, when the square buckle 13 is used to fix the bracket to limit the bracket from rotating in the orthodontic positioner and falling off from the orthodontic positioner, there is no need to use hydrosol to fix the bracket, thereby eliminating the use of hydrosol, saving materials and costs, and achieving the effect of stable retention of the bracket on the orthodontic positioner without using hydrosol retention. This method not only effectively improves the stability of the orthodontic positioner, but also makes the separation of the bracket and the positioner more convenient and quick, thereby greatly improving the operating efficiency and accuracy of medical staff.

[0039] In order to further limit the bracket from rotating and falling off from the locator and improve the accuracy of the bracket being installed on the tooth surface, the clamping part 1 also includes a straight arm buckle 14. In this embodiment, two straight arm buckles 14 are provided. Figures 5 to 8 As shown, the two straight arm buckles 14 are respectively arranged at the front ends of both sides of the clamping groove 11. Specifically, the two straight arm buckles 14 smoothly transition to the front ends of both sides of the clamping groove 11. The two straight arm buckles 14 are stacked along the central axis of the clamping groove 11, and the two straight arm buckles 14 are stepped as a whole, that is, each straight arm buckle 14 gradually decreases from the inner wall of the clamping groove 11 to the central axis direction of the clamping groove 11. At this time, the bottom surface of the straight arm buckle 14 smoothly transitions to the top surface, so that the straight arm buckle 14 is completely fitted with the gingival chamfer of the bracket, further limiting the rotation of the bracket from the orthodontic positioner and falling off from the orthodontic positioner, making the position of the bracket on the orthodontic positioner more stable, and further improving the stability of clamping the orthodontic positioner.

[0040] At the same time, in order to enable the bracket to further align with the installation position on the tooth surface and ensure that the installation position of the bracket is not offset, the orthodontic positioner is also provided with a structure for auxiliary bracket positioning and installation. At this time, the nesting part 2 is used to assist the bracket to be installed on the tooth surface. Specifically, the nesting part 2 includes a tooth socket groove 21, and the tooth socket groove 21 is arranged on one side of the connection between the nesting part 2 and the tooth, such as Figures 5 to 8As shown, the socket 21 is concave inward, and the surface of the socket 21 is uneven. At this time, the surface of the socket 21 matches the outer contour of the tooth crown, so that the socket 21 can be more stably mounted on the tooth, preventing the socket 21 from shaking when it is mounted on the tooth, thereby ensuring that the bracket will no longer shake after being aligned with the tooth surface, and can allow the bracket to be accurately installed on the tooth surface.

[0041] Furthermore, in order to enhance the stability of the socket 21 when it is mounted on the teeth, the nesting portion 2 also includes a support member 22, which is arranged at the front end of the orthodontic positioner. Compared with the socket 21, the support member 22 is more protruding, and the support member 22 is formed by extending from the inner wall of one side of the socket 21. When the socket 21 is mounted on the teeth, the support member 22 just abuts against the surface of the teeth, thereby providing support for the orthodontic positioner, so that the socket 21 can be stably mounted on the teeth, preventing the socket 21 from shaking when it is mounted on the teeth, and improving the stability of the socket 21.

[0042] Since the nesting part 2 includes a tooth socket 21, the surface of the tooth socket 21 matches the outer contour of the tooth crown, but the outer contour of the tooth crown of each tooth is different, that is, each orthodontic positioner corresponds to a different tooth. When installing the orthodontic positioner, it is necessary to identify which tooth each orthodontic positioner needs to be installed on. At this time, the identification part 3 is used to identify which tooth a certain orthodontic positioner needs to be installed on. Specifically, the identification part 3 includes a tooth position identification point 31.

[0043] Furthermore, the identification portion 3 also includes a press identification point 32, and the press identification point 32 is arranged on the tooth position identification point 31, and the tooth position identification point 31 is arranged on the side of the nesting portion 2 away from the teeth, that is, when the orthodontic locator is installed, the tooth position identification point 31 faces the side of the medical staff who installs the orthodontic locator, so as to facilitate identification by the medical staff, so that the medical staff can determine which tooth in the patient's mouth the orthodontic locator needs to be installed on through the tooth position identification point 31. Specifically, in this embodiment, the tooth position identification point 31 is a number, that is, each number corresponds to a specific tooth, so that the medical staff can determine to install the orthodontic locator on the specified tooth according to the number.

[0044] At the same time, in order to allow medical personnel to install the orthodontic positioner more conveniently and accurately, the marking portion 3 also includes a pressing marking point 32, such as Figures 5 to 8As shown, the pressing mark point 32 is set beside the tooth position mark point 31. The pressing mark point 32 is semi-cylindrical and protrudes from the nesting portion 2. Specifically, when the medical staff presses the pressing mark point 32 with their hands, the rounded and curved outer surface of the mark point brings the medical staff a more comfortable hand feel, and also helps the medical staff find the correct pressing area and pressing direction when bonding the bracket. The position of the mark point is set at the center point of the occlusal surface of the tooth. Pressing the position of the pressing mark point can guide the medical staff to apply force to the center point of the occlusal surface of the tooth during the process of pressing the orthodontic locator, thereby avoiding the orthodontic locator not being fully in place on the tooth due to the pressing position being biased towards the lip / cheek side or the tongue / palate side when the orthodontic locator is in place on the tooth, resulting in bonding errors.

[0045] To summarize, when it is necessary to use the orthodontic positioner in the present application to install the bracket, first fix the bracket on the orthodontic positioner through the clamping groove 11. At this time, the square buckle 13 and the straight arm buckle 14 further fix the bracket on the orthodontic positioner to prevent the bracket from rotating and falling off the orthodontic positioner. Then, the orthodontic positioner is installed on the tooth through the socket groove 21. At this time, the orthodontic positioner is accurately installed on the tooth by pressing the marking point 32, so that the bracket can be accurately installed on the tooth surface of the tooth. Then, the orthodontic positioner is removed and the bracket is left on the tooth surface of the tooth to complete the installation of the bracket.

[0046] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made according to the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
