Description

Technical Field

[0001] The invention relates to the technical field of oral orthodontic devices, in particular to a molar pushing and moving backward device used in oral orthodontic clinics. Background Art

[0002] In oral orthodontic clinics, malocclusion accompanied by dental crowding is common, and is usually corrected by tooth extraction or pushing the molars backwards. Pushing the molars backwards is a more commonly used non-extraction correction method. This method pushes the molars backwards, corrects the relationship between the molars, expands the dental arch space, and provides space for leveling and alignment, thereby maintaining the natural physiological state of the oral and maxillofacial system and stabilizing the occlusal relationship.

[0003] Based on the above, the inventors have found that the existing clinical orthodontic device for pushing molars backward has the following shortcomings. For example, the existing device for moving molars backward uses an elastic leather ring to pull the guide ring. After the elastic leather ring pulls the guide ring to move the teeth backward for a certain period of time, the elasticity of the elastic leather ring will gradually decrease as the teeth move backward. It is necessary to manually adjust the guide ring to keep the elastic leather ring in a taut state. It is inconvenient to adjust the guide ring every time in the hospital. In addition, the elastic leather ring is annular in shape and is easily broken by friction in the mouth, thereby affecting the orthodontics of the oral teeth. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] Example 1: Please refer to Figure 1-Figure 5 , the specific embodiments of the present invention are as follows:

[0025] Its structure includes a fixed seat 1, a guide bar 2, and a main body 3. The fixed seats 1 are provided with two, the guide bars 2 are provided with two, and the guide bars 2 are fixedly connected to the end faces of the two fixed seats 1 respectively, and the two ends of the main body 3 are fixedly connected to the end faces of the two fixed seats 1 respectively.

[0026] The main body 3 includes a connecting strip 31, a locking pin 32, a locking device 33, a guide ring 34, and a traction device 35. Two connecting strips 31 are provided, and the connecting strips 31 are respectively fixedly connected to the end faces of the fixing seat 1. Four locking pins 32 are provided, and the locking pins 32 are used in groups of two to fix the connecting strip 31 on the gums of an orthodontic patient. The end face of the guide ring 34 is annular, which is conducive to traction of the guide ring 34 through the elasticity of the traction device 35, so that the guide ring 34 can maintain a certain pulling force to correct the teeth that need orthodontics.

[0027] The locking device 33 includes a locking block 331, a latch tooth 332, and a ceramic sealing block 333. The locking block 331 is fixedly connected to the end face of the connecting strip 31. The latch teeth 332 are provided with eight rows, and the latch teeth 332 are symmetrically fixed to the inner end face of the locking block 331 in a group of two. The ceramic sealing block 333 is fixedly installed on the end face of the locking block 331. The latch teeth 332 are inclined 30 degrees from the front end to the rear end, which can reduce the friction between the latch teeth 332 and the guide ring 34, which is beneficial for clamping the two sides of the guide ring 34 through the latch teeth 332, so that the guide ring 34 keeps the teeth in a tensioned state.

[0028] The guide ring 34 includes a ring body 341, a block 342, and an anti-skid groove 343. The ring body 341 passes through the interior of the locking block 331, and the two ends of the ring body 341 are fixedly connected to the block 342 respectively. The two ends of the block 342 are respectively engaged with the end faces of the latch teeth 332. There are eight anti-skid grooves 343, and the anti-skid grooves 343 are arranged in groups of four on the end faces of both sides of the block 342. The two ends of the block 342 are in the shape of thin sheets and have a certain degree of elasticity. The side ends of the block 342 can be deformed and fixed on the end faces of the latch teeth 332, which is beneficial to increase the friction through the contact between the anti-skid groove 343 and the end faces of the latch teeth 332, and improve the stability of the block 342 stuck on the end faces of the latch teeth 332.

[0029] The ceramic sealing block 333 includes a ceramic ring a1, a fixed ring a2, and a barb a3. The ceramic ring a1 is clamped and connected to the end face of the locking block 331, and the fixed ring a2 is clamped on the inner end face of the ceramic ring a1. The barb a3 has two end faces respectively fixedly connected to the fixed ring a2, and the barb a3 is engaged with the inner end face of the ceramic ring a1. The end face of the ceramic sealing block 333 is a smooth end face, which can contact with the end face of the guide ring 34 to play a sealing role, which is conducive to achieving a sealed state through the contact between the smooth end face of the ceramic ring a1 and the guide ring 34, thereby avoiding the situation where saliva is placed inside the locking block 331 to cause bad breath.

[0030] Based on the above embodiment, the specific working principle is as follows: the connecting strip 31 is fixed on the gums by the locking nail 32, so that the fixing seat 1 can be put on the patient's back teeth, and then the guide ring 34 is pulled by the elasticity of the traction device 35, so that the guide ring 34 can maintain a certain tension to correct the teeth that need orthodontics, and the guide strip 2 can be relied on the inner side of the teeth to guide the orthodontics of the teeth, and assist the flatness of the orthodontics of the teeth. When the traction device 35 is used to pull the guide ring 34 backward to perform orthodontics on the teeth, the two sides of the guide ring 34 are clamped by the clamping teeth 332, so that the guide ring 34 can keep the teeth in a taut state, assist the orthodontics of the teeth, improve the efficiency of orthodontics, and there is no need to go to the hospital for short-term examination. The ring body 341 is then used to move into the interior of the locking block 331, and then the two sides of the block 342 are squeezed by the latch teeth 332 to deform and move backward, so that the block 342 is stuck on the end face of the latch teeth 332 for fixation, and then the anti-slip groove 343 is used to contact the end face of the latch teeth 332 to increase the friction force, thereby improving the stability of the block 342 stuck on the end face of the latch teeth 332. Finally, the ceramic ring a1 is matched with the inverted hook a3 on the end face of the fixing ring a2 to fix the ceramic ring a1 inside the locking block 331, so that the guide ring 34 can slide against the inner end face of the ceramic ring a1, and the smooth end face of the ceramic ring a1 is in contact with the guide ring 34 to achieve a sealed state, thereby preventing saliva from being placed inside the locking block 331 and causing bad breath.

[0031] Example 2: Please refer to Figure 6-Figure 7 , the specific embodiments of the present invention are as follows:

[0032] The traction device 35 includes a connecting seat 351, a locking buckle 352, a traction head 353, an elastic leather ring 354, and a hook 355. The connecting seat 351 is fixedly connected to the end face of the guide ring 34, the locking buckle 352 is fixedly connected to the guide ring 34, and locks the connecting seat 351 to the end face of the guide ring 34, the traction head 353 is fixedly connected to the end face of the connecting seat 351, the elastic leather ring 354 is hung in the traction head 353, the hook 355 can be locked in the gums, and the hook 355 is connected to the elastic leather ring 354. The traction head 353 is spherical in shape, which can reduce the friction of the elastic leather ring 354, which is beneficial for the elastic leather ring 354 to pull the traction head 353 through its own elasticity to assist the teeth in orthodontics.

[0033] The elastic leather ring 354 includes a rubber ring s1, a protective sleeve s2, and a rubber pad s3. One end of the rubber ring s1 is fixedly connected to the traction head 353, and the other end of the rubber ring s1 is fixedly connected to the end face of the hook 355. The protective sleeve s2 is nested in the outer end face of the rubber ring s1. Two rubber pads s3 are provided, and the rubber pads s3 are respectively clamped and connected to the front and rear end faces of the protective sleeve s2. The interior of the protective sleeve s2 is cylindrical, which is beneficial for the protective sleeve s2 to protect the end face of the rubber ring s1 and prevent the rubber ring s1 from being broken due to friction in the mouth.

[0034] Based on the above embodiment, the specific working principle is as follows: one end of the elastic leather ring 354 is hung on the end face of the traction head 353, and the other end is hung on the end face of the hook 355. The traction head 353 is pulled by the elasticity of the elastic leather ring 354 itself, and the guide ring 34 is pulled by the traction force to perform orthodontic treatment on the teeth. The rubber ring s1 is then passed through the inside of the protective sleeve s2 to protect the end face of the rubber ring s1 and prevent the rubber ring s1 from being broken due to friction in the oral cavity. The rubber pad s3 can reduce the friction force of the protective sleeve s2 on the rubber ring s1, so that the rubber ring s1 can provide stable pulling force in the oral cavity to pull the guide ring 34, thereby playing a role in assisting oral orthodontics.
