Technical Field

[0001] The utility model belongs to the field of bracketless tooth correction devices, and in particular relates to a bracketless device for tooth correction. Background Art

[0002] Deformed teeth can affect the normal development of maxillofacial soft tissues, causing deformities in the patient's appearance. Deformed teeth can also affect the bite, leading to impaired chewing function, inadequate grinding of food, which can affect digestion, increase the difficulty of brushing teeth, and affect oral health. In order to avoid these problems, orthodontic treatment is often required. In order to ensure aesthetics, people now usually choose bracketless devices for orthodontic treatment.

[0003] Currently, existing bracketless devices for orthodontics often achieve the goal of controlling the magnitude and duration of the corrective force by making multiple bracketless devices. This design requires patients to frequently visit the hospital to make and obtain new bracketless devices. This step is too cumbersome and requires patients to spend a lot of time.

[0004] Therefore, in order to address the problem that the existing bracketless devices for orthodontics require patients to spend a lot of time going to the hospital to make and use new bracketless devices in order to ensure the control of the magnitude and duration of the correction force, the existing bracketless devices for orthodontics are improved by adding adjustment functions so that patients can adjust the bracketless devices according to their own conditions, thereby adjusting the magnitude of the correction force of the bracketless devices without having to replace new ones. Utility Model Content

[0005] In order to overcome the problem that existing bracketless devices do not have an adjustment function, patients need to spend too much time making and replacing new bracketless equipment to achieve the control of the correction force and the duration of action.

[0007] Preferably, a slider fixedly installed at the bottom end of the external tooth correction plate and the internal tooth correction plate is driven by a fixed moving component to move in a slide groove opened on the support frame, thereby changing the distance between the external tooth correction plate and the internal tooth correction plate, and realizing the adjustment of the correction force and force application time of the bracketless device without replacing the bracketless device.

[0008] Preferably, there are four sliders, which are fixedly connected to the No. 1 external teeth correction plate, the No. 1 internal teeth correction plate, the No. 2 external teeth correction plate and the No. 2 internal teeth correction plate respectively. The sliders drive the external teeth correction plate and the internal teeth correction plate to move in opposite directions, thereby changing the correction force applied by the upper teeth corrector and the lower teeth corrector to the patient's teeth, correcting the patient's upper and lower teeth to restore their normal occlusion state.

[0009] Preferably, two limit groups are installed on the No. 1 support frame and the No. 2 support frame respectively, and each limit group consists of four limit plates. The design of the limit group can install the moving component on the outside of the tooth, avoiding the moving component from causing damage to the patient's tooth and oral cavity when using a bracketless device for correction.

[0010] Preferably, the No. 1 external teeth correction plate and the No. 1 internal teeth correction plate are arranged in corresponding limiting groups, and the No. 2 external teeth correction plate and the No. 2 internal teeth correction plate are arranged in corresponding limiting groups. The limiting groups cooperate with the slide grooves to limit the positions of the internal teeth correction plate and the external teeth correction plate to prevent them from being too wide and occupying too much oral space of the patient.

[0011] Preferably, the movable assembly includes a threaded rod, a limit column and a knob; the threaded rod is inserted into the two adjacent limit plates on one side of the No. 1 support frame and the two adjacent limit plates on the same side of the No. 2 support frame, the limit columns are fixedly connected to the two limit plates on the other side of the No. 1 support frame and the two adjacent limit plates on the same side of the No. 2 support frame, and a knob fixedly connected to the threaded rod is provided on the outside of the front limit plate. Turning the knob drives the threaded rod to rotate. The threaded rod is a bidirectional threaded rod with two front and rear opposite threaded structures fixedly connected on the outside.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See also Figures 1-6The utility model provides an embodiment: it includes an upper tooth corrector composed of a No. 1 support frame 1, a No. 1 external tooth correction plate 2 and a No. 1 internal tooth correction plate 3, a lower tooth corrector composed of a No. 2 support frame, a No. 2 external tooth correction plate 11 and a No. 2 internal tooth correction plate 12, a slide 4, a slider 5 and a moving component; the No. 1 support frame 1 is provided with an external tooth correction plate located on the outside of the patient's upper gum, the No. 1 support frame 1 is provided with an internal tooth correction plate located on the inside of the patient's lower gum, the upper tooth corrector is sleeved on the patient's upper gum, and a lower tooth corrector opposite to the upper tooth corrector is provided below the No. 1 support frame 1, and the lower tooth corrector is sleeved on On the lower dental bed, a slide groove 4 is provided on the No. 1 support frame 1 and the No. 2 support frame, and a slider 5 is installed in the upper and lower braces. The slider 5 is movably connected to the corresponding slide groove 4. The upper and lower braces are respectively equipped with moving components for adjusting the correction force of the upper and lower braces. The slider 5 fixedly installed at the bottom end of the outer and inner correction plates is driven by the fixed moving component to move in the slide groove 4 provided on the support frame, so as to change the distance between the outer and inner correction plates. Without replacing the bracketless device, the correction force and force application time of the bracketless device can be adjusted.

[0027] See also Figures 1-4 , In this embodiment, there are four sliders 5, which are respectively fixedly connected to the No. 1 external tooth correction plate 2, the No. 1 internal tooth correction plate 3, the No. 2 external tooth correction plate 11 and the No. 2 internal tooth correction plate 12. Two limit groups 6 are respectively installed on the No. 1 support frame 1 and the No. 2 support frame, and each limit group 6 is composed of four limit plates. The No. 1 support frame 1 and the No. 2 support frame are respectively equipped with two limit groups 6, and each limit group 6 is composed of four limit plates. The slider 5 drives the external tooth correction plate and the internal tooth correction plate to move in relative directions, thereby changing the correction force applied to the patient's teeth by the upper and lower teeth correctors, correcting the patient's upper and lower teeth to restore their normal occlusion state. The design of the limit group 6 can install the moving component on the outside of the tooth flower, avoiding damage to the patient's tooth flower and oral cavity caused by the moving component when using a bracketless device for correction. The limit group 6 cooperates with the slide groove 4 to limit the position of the internal tooth correction plate and the external tooth correction plate, avoiding that they are too wide and occupy too much oral space of the patient.

[0028] See also Figure 2 、 Figure 3 、 Figure 5 、 Figure 6, in this embodiment, the moving assembly includes a threaded rod 701, a limiting column 702 and a knob 703; the two limiting plates adjacent to one side of the No. 1 support frame 1 and the two limiting plates adjacent to the same side of the No. 2 support frame are both plugged with threaded rods 701, the two limiting plates on the other side of the No. 1 support frame 1 and the two limiting plates adjacent to the same side of the No. 2 support frame are both fixedly connected to the limiting column 702, and the front limiting plate is provided with a knob 703 fixedly connected to the threaded rod 701, the No. 1 external tooth correction plate 2, the No. 1 internal tooth correction plate 3 are screwed onto the threaded rod 701 located above the No. 1 support frame, the No. 2 external tooth correction plate 11 and the No. 2 internal tooth correction plate 12 are screwed onto the threaded rod 701 located below the No. 2 support frame 10, the No. 1 external tooth correction plate 2 and the No. 1 internal tooth correction plate 3 are sleeved onto the outside of the limiting column 702 located above the No. 1 support frame, the No. 2 external tooth correction plate 11 and the No. 2 internal tooth correction plate 12 are sleeved onto the outside of the limiting column 702 located below the No. 2 support frame 10, and the No. 1 external tooth correction plate 2 and the No. 2 external tooth correction plate 11 are respectively fixed on There are two No. 1 fixing plates 8, and the No. 1 internal tooth correction plate 3 and the No. 2 internal tooth correction plate 12 are respectively fixedly connected to the two No. 2 fixing plates 9. Turning the knob 703 drives the threaded rod 701 to rotate. The threaded rod 701 is a bidirectional threaded rod 701 with two front and rear threaded structures fixedly connected to the outside. After the staff turns the upper and lower knobs 703 respectively, the knob 703 drives the threaded rod 701 movably inserted in the two limit plates to rotate. Under the restriction of the limit column 702, the external tooth correction plate and the internal tooth correction plate screwed in different threaded areas move in opposite directions with the rotation of the threaded rod 701, thereby achieving the effect of adjusting the correction force of the entire bracketless device. The No. 1 fixing plate 8 cooperates with the No. 2 fixing plate 9 to sleeve the entire bracketless device on the outside of the patient's teeth. The patient's teeth are located in the two No. 2 fixing plates 9. The staggered design between the No. 1 fixing plate 8 and the No. 2 fixing plate 9 can avoid the No. 1 fixing plate 8 and the No. 2 fixing plate 9 from squeezing each other when adjusting the distance between the external tooth correction plate and the internal tooth correction plate.

[0029] During the work, the medical staff first automatically generates a model through computer software based on the patient's face and teeth scan, and then generates a bracketless device based on the model. The patient puts the bracketless device on the teeth, and the second fixing plate 9 is clamped on the outside of the patient's outermost teeth to achieve fixation. Through the connection of the outer tooth correction plate and the inner tooth correction plate and the long-term application of force, the patient's teeth are slowly moved to the correct position;

[0030] After wearing braces for a period of time, the patient's mouth and teeth have adapted to the current correction force. The bracketless device is removed, wiped clean with a tissue, and the knob 703 is turned. Under the restriction of the limit column 702, the outer tooth correction plate and the inner tooth correction plate on the threaded rod 701 with a bidirectional thread structure are moved toward the middle, and then the braces are put back on to adapt to the new correction force.

[0031] Through the above steps, the existing bracketless device for orthodontics is improved, and its original fixed integrated design is changed into a design composed of a support frame, an external tooth correction plate and an internal tooth correction plate. The fixed moving component is used to drive the slider 5 fixedly installed at the bottom end of the external tooth correction plate and the internal tooth correction plate to move in the slide groove 4 opened in the support frame, so as to change the distance between the external tooth correction plate and the internal tooth correction plate. Without replacing the bracketless device, the correction force and force application time of the bracketless device can be adjusted, so as to solve the problem that the existing bracketless device does not have an adjustment function and requires patients to spend too much time to make and replace new bracketless equipment to achieve the control of the correction force and action time.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
