Description

Technical Field

[0001] This invention relates to the field of molar orthodontic technology, specifically to a traction mechanism for local molar straightening. Background Technology

[0002] Molars, also known as cuspids, are teeth located at the back of the mouth used for chewing and grinding food. They include premolars and molars and are the teeth with the strongest biting force in the mouth. During their natural growth, molars are prone to becoming misaligned, affecting normal chewing and occlusion. Current treatment primarily involves adjusting the misaligned molars (such as tilted or crooked teeth) to their normal biting position. The aim is to restore proper tooth alignment and biting function, preventing problems such as food impaction and tooth decay caused by misaligned teeth. The utility model disclosed in CN219940831U is a partial orthodontic appliance for traction molars. By setting a first cast band ring and a second cast band ring, it can provide traction force through the molars on the opposite side of the molar to be tractioned, so as to effectively ensure anchorage stability. Specifically, it can change the traction force between the molar to be tractioned and the adjacent molars by tightening the chain rings on the omega flexure and the buccal tube. It is easy to adjust, has fewer parts, simple structure, easy to install and adjust, and low overall manufacturing cost, which effectively reduces the cost of orthodontic treatment and also reduces the number of healthy teeth affected.

[0003] The utility model disclosed in CN220442750U is a mesial tilt second molar upright orthodontic appliance, which controls the orthodontic force of the elastic traction element on the second molar between 100g and 200g, so that the appliance regains the ability to correct the second molar. The cycle repeats, and the user only needs to use one main appliance to straighten the second molar. Its cost is far lower than that of invisible orthodontics, which requires many appliances.

[0004] However, the aforementioned orthodontic traction device for local molars still has the following problems in actual use: the traction mechanism connected to the molars is used to pull the tilted molars, but this type of traction mechanism is fitted on the outside of multiple molars. When the frame is used, it is easy to cause the fitted molars to change their original position and occupy more oral space. At the same time, some molars have different tilt angles, and the traction mechanism cannot make the required angle adjustment, which in turn causes the molars to deflect and affect normal traction.

[0005] Therefore, we propose a traction mechanism for local molar straightening to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a traction mechanism for local molar straightening. This addresses the problem that existing traction mechanisms, which are connected to the molars, are used to pull tilted molars. However, such traction mechanisms are fitted around multiple molars, and when the frame is used, the fitted molars are prone to changing their original position and occupying more oral space. In addition, some molars have different tilt angles, and the traction mechanism cannot make the required angle adjustment, which leads to the molars deflecting and affecting normal traction.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a traction mechanism for local molar orthodontic correction, comprising a jawbone body, and molar bodies disposed at equal intervals above the jawbone body, and an oblique tooth body adjacent to the molar bodies disposed above the jawbone body; further comprising: A positioning mechanism is provided above the tooth body, and the positioning mechanism includes a positioning ring sleeve, which is sleeved and installed on the upper outer wall of the molar body. The positioning mechanism includes an adjustable outer frame, and a positioning vertical plate is fixedly installed at the center of the inner part of the adjustable outer frame; A traction mechanism is provided above the dental body, and the traction mechanism includes a traction plate, which is glued to the middle of the top surface of the inclined dental body.

[0008] Preferably, the positioning mechanism includes a positioning ring with a hollow structure, which is connected to the molar body. The positioning ring is glued to the outer wall of the molar body and does not adhere to the jaw body.

[0009] Preferably, the positioning mechanism includes an adjusting outer frame that is fixedly installed on the front of the positioning ring, and a positioning slot is provided at the center of the positioning vertical plate inside the adjusting outer frame, and the inside of the positioning slot is connected to the right end of the traction hook rod.

[0010] Preferably, the positioning mechanism includes an adapter groove, which is located at the left end of the adjusting frame, and the interior of the adapter groove is connected to the end of the traction hook rod away from the positioning slot, and the left end of the traction hook rod extends to the side above the jawbone body near the oblique tooth body.

[0011] Preferably, the positioning mechanism includes locking screw holes, which are opened on the left and right sides of the front of the adjusting frame. The internal threads of the symmetrically arranged locking screw holes are connected to the rear end of the locking screw, and the rear end of the locking screw extends to the left and right sides inside the adjusting frame.

[0012] Preferably, the positioning mechanism includes an adjusting ramp, which is slidably installed on the left and right sides inside the adjusting frame. The symmetrically arranged adjusting ramps are fixedly connected to the rear end of the locking screw, and the back of the symmetrically arranged adjusting ramps are attached to the outer wall of the traction hook rod.

[0013] Preferably, the traction mechanism includes a traction shaft, the lower end of which is fixedly installed at the center of the top surface of the traction sticky plate, and a limiting convex ball is fixedly provided at the top of the traction shaft. Furthermore, a limiting cone is fixedly provided on the upper outer wall of the traction shaft, and the limiting cone is distributed in a manner that is narrower at the top and wider at the bottom.

[0014] Preferably, the traction mechanism includes an elastic traction belt, and the right end of the elastic traction belt is sleeved on the outer wall of the traction shaft above the traction adhesive plate. The traction shaft limits the elastic traction belt through the upper limiting convex ball and limiting cone to prevent the elastic traction belt from slipping upward.

[0015] Preferably, the left end of the elastic traction band included in the traction mechanism is sleeved on the left end of the traction hook rod, and the left end of the traction hook rod is distributed in an inwardly bent semi-circular structure. The inward bending of the left end of the traction hook rod prevents the elastic traction band from slipping off, and at the same time prevents the user from being obstructed or scratched while chewing.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This traction mechanism for partial molar orthodontic treatment uses a positioning ring sleeve fitted around the outside of the molar body. The adjusting frame outside the positioning ring locks and adjusts the angle of the traction hook rod. In addition to providing traction force in the opposite direction during traction orthodontic treatment, it can also assist the inclined tooth body in adjusting the deflection angle, thereby improving the orthodontic efficiency. The specific details are as follows: 1. Adjust the specifications and shape of the positioning ring according to the specifications of the adjacent molar bodies. The positioning ring is customized by the dental mold of the molar body and is glued to the outside of the molar body during installation, thereby avoiding gaps or interference connections between the positioning ring and the molar body, which could cause damage to the molar body.

[0017] 2. By passing the right end of the traction hook rod through the matching transverse slot opened on the left end of the adjusting frame, and simultaneously passing the right end of the traction hook rod through the positioning slot hole opened inside the positioning vertical plate, the traction hook rod is limited to prevent deviation in other directions during the correction traction operation.

[0018] Furthermore, the locking screw is installed through the locking screw hole on the front of the adjusting frame. The locking screws on both sides are rotated synchronously, which drives the adjusting ramp at the rear end to move into the adjusting frame. This causes the inclined structure of the adjusting ramp to press against the right end of the traction hook rod and achieve positioning in conjunction with the positioning slot, thereby improving the stability of the traction hook rod during subsequent traction operations.

[0019] 3. When the inclined tooth body has a certain angular deflection in addition to tilting, the locking screws on the left and right sides are rotated in opposite directions, thereby causing the adjusting inclined plates on the left and right sides to be distributed in a staggered manner so that the traction hook rods can be adjusted axially and distributed opposite to the deflection angle of the inclined tooth body. In addition to providing traction in the opposite direction during traction orthodontic treatment, it can also assist the inclined tooth body in adjusting the deflection angle and improve the straightening efficiency.

[0020] 4. By installing the traction plate on the top center of the inclined tooth body, the right end of the elastic traction belt is sleeved on the outer wall of the traction shaft, and the upper limiting convex ball and limiting cone are used to limit the elastic traction belt to prevent it from slipping off due to the tilt angle of the inclined tooth body.

[0021] Furthermore, the left end of the elastic traction belt is fitted onto the left end of the traction hook rod. The traction hook rod limits the elastic traction belt through a circular bend at its left end. This prevents the elastic traction belt from becoming misaligned during traction operations and reduces obstruction and friction to the user's chewing movements. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: To address the problems existing in the current treatment of local molar orthodontic correction, this example discloses the following technical solution: a traction mechanism for local molar orthodontic correction, comprising a jaw body 1, and a molar body 2 disposed at equal distances above the jaw body 1, and an oblique tooth body 3 adjacent to the molar body 2 disposed above the jaw body 1; a positioning mechanism is disposed above the jaw body 1, and the positioning mechanism includes a positioning ring 4, which is fitted and installed on the upper outer wall of the molar body 2; wherein, the positioning mechanism includes an adjusting frame 5, and a positioning vertical plate 6 is fixedly disposed at the internal center position of the adjusting frame 5.

[0026] The positioning mechanism includes a hollow positioning ring 4, which is connected to the molar body 2. The positioning ring 4 is glued to the outer wall of the molar body 2 and does not fit against the jaw body 1. The positioning mechanism includes an adjusting frame 5, which is fixedly installed on the front of the positioning ring 4. The center of the positioning vertical plate 6 inside the adjusting frame 5 is provided with a positioning slot 8, and the inside of the positioning slot 8 is connected to the right end of the traction hook rod 9. The positioning mechanism includes an adapting transverse groove 10, which is opened at the left end of the adjusting frame 5. The inside of the adapting transverse groove 10 is connected to the end of the traction hook rod 9 away from the positioning slot 8, and the left end of the traction hook rod 9 extends to the side above the jaw body 1 near the oblique tooth body 3.

[0027] The positioning mechanism includes locking screw holes 11, which are located on the left and right sides of the front of the adjusting frame 5. The internal threads of the symmetrically arranged locking screw holes 11 are connected to the rear end of the locking screw 12, and the rear end of the locking screw 12 extends to the left and right sides inside the adjusting frame 5. The positioning mechanism includes adjusting ramps 13, which are slidably installed on the left and right sides inside the adjusting frame 5. The symmetrically arranged adjusting ramps 13 are fixedly connected to the rear end of the locking screw 12, and the back of the symmetrically arranged adjusting ramps 13 are attached to the outer wall of the traction hook rod 9.

[0028] like Figures 6-8 As shown, when it is necessary to traction and straighten the oblique tooth body 3 above the jaw body 1, the specifications and shape of the positioning ring 4 are first adjusted according to the specifications of the adjacent molar body 2 of the oblique tooth body 3. The positioning ring 4 is customized by the dental mold of the molar body 2 and is glued to the outside of the molar body 2 during installation, so as to avoid damage caused by gaps or interference fits between the molar body 2 and the positioning ring 4.

[0029] Furthermore, by passing the right end of the traction hook rod 9 through the positioning slot 8 opened at the left end of the adjusting frame 5, and simultaneously passing through the positioning slot 8 opened inside the positioning vertical plate 6 in the middle of the adjusting frame 5, the traction hook rod 9 is limited by the positioning slot 8 to prevent deviations other than the required direction. At the same time, the locking screw 12 is connected through the locking screw hole 11 opened on the front of the adjusting frame 5. By rotating the locking screw 12 synchronously, the adjusting inclined plate 13 fixedly connected at the rear end is moved backward. The adjusting inclined plates 13 on the left and right sides press the rear end of the traction hook rod 9 through the inclined surface to achieve positioning and locking, thereby improving the stability of the traction hook rod 9 during subsequent traction operations.

[0030] like Figure 5 , Figures 9-10 As shown, when the inclined tooth body 3 above the jaw body 1 has an angular deviation problem and it is necessary to adjust the installation angle of the traction hook rod 9, by rotating the locking screws 12 on the left and right sides in opposite directions, the locking screws 12 on the left and right sides move in an advancing and retreating manner, and drive the adjusting inclined plates 13 on the left and right sides to squeeze the traction hook rod 9 in a staggered manner, thereby driving the left end of the traction hook rod 9 to rotate around the molar body 2, so as to straighten and correct the angular deviation of the molar body 2 through the traction method in the opposite direction.

[0031] Example 2: In order to solve the problems existing in the treatment of local molars, this example discloses the following technical solution: A traction mechanism is provided on the upper part of the jaw body 1, and the traction mechanism includes a traction plate 7, which is glued to the middle of the top surface of the inclined tooth body 3; the traction mechanism includes a traction shaft 14, and the lower end of the traction shaft 14 is fixedly installed at the center of the top surface of the traction plate 7, and a limiting convex ball 15 is fixedly provided at the top of the traction shaft 14, and a limiting cone 16 is fixedly provided on the upper outer wall of the traction shaft 14, with the limiting cone 16 distributed in a way that is narrow at the top and wide at the bottom.

[0032] The traction mechanism includes an elastic traction band 17, the right end of which is sleeved on the outer wall of the traction shaft 14 above the traction adhesive plate 7. The traction shaft 14 limits the elastic traction band 17 through the upper limiting convex ball 15 and limiting cone 16 to prevent the elastic traction band 17 from slipping upward. The left end of the elastic traction band 17 is sleeved on the left end of the traction hook 9. The left end of the traction hook 9 has an inwardly bent semi-circular structure. The inward bending of the left end of the traction hook 9 prevents the elastic traction band 17 from slipping and also prevents the user from being obstructed or scratched while chewing.

[0033] like Figures 2-4 , Figure 7 As shown, the traction plate 7 is glued and installed on the top center of the incline body 3. Then, the right end of the elastic traction band 17 is fitted and installed on the outer wall of the traction shaft 14 above the traction plate 7. The limiting convex ball 15 and the limiting cone 16 above the traction shaft 14 are both located above the elastic traction band 17, thereby preventing slippage under subsequent traction at different angles and inclinations. At the same time, the left end of the elastic traction band 17 is fitted and installed on the left end of the traction hook 9. The circular bending mechanism at the left end of the traction hook 9 prevents the elastic traction band 17 from being misaligned during oblique orthodontic treatment, and also prevents obstruction and scratches to the user during chewing.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
