Description

Technical Field

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

[0002] Impaired development of maxillofacial soft tissues can lead to deformed appearance of the patient, while misaligned teeth can lead to impaired chewing function and inadequate grinding of food, which can affect digestion. These are all effects of malocclusion. At the same time, the difficulty of brushing teeth due to misaligned teeth can also affect the patient's oral health. In order to avoid these problems, dental braces are needed for treatment. In order to ensure aesthetics, people now often use invisible orthodontic devices to treat patients.

[0003] At present, the existing invisible orthodontic correction devices are made of resin materials, and their retention and force transmission functions on the dentition are often weak and have little effect. They are often used as retainers in the later stages of treatment and have poor versatility.

[0004] Therefore, in order to address the problem that the existing invisible orthodontic devices have weak correction force and poor versatility, the existing invisible orthodontic devices are improved by adding auxiliary connecting rods that can increase the correction force, and connecting the upper and lower braces together through hooks and hanging rings to improve the patient's mandibular position. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See also Figures 1-6The present invention provides an embodiment: an invisible orthodontic correction device for teeth comprises an upper brace 1, a lower brace 2, an auxiliary connecting rod 3, a hook 4 and a hanging ring 5; the upper brace 1 is sleeved on the outer side of the patient's upper teeth, and a lower brace 2 sleeved on the patient's lower teeth is provided below the upper brace 1. Auxiliary connecting rods 3 opposite to each other are movably connected between the upper brace 1 and the lower brace 2, and a hook 4 is provided on the auxiliary connecting rod 3. The upper brace 1 is fixedly connected with a left-right symmetrical hanging ring 5, and the hook 4 passes through the hanging ring 5. By adding an auxiliary connecting rod 3 for connecting between the upper brace 1 and the lower brace 2 on the existing invisible orthodontic correction device, the auxiliary connecting rod 3 is connected to the upper brace 1 and the lower brace 2 through the hook 4 and the hanging ring 5, thereby improving the correction force of the invisible orthodontic correction device for teeth.

[0026] See also Figure 1-Figure 4 In this embodiment, a telescopic slot 6 is provided in the auxiliary connecting rod 3, a telescopic rod 7 is movably connected in the telescopic slot 6, a hook 4 is fixedly connected to the telescopic rod 7, a guide rod 8 is fixedly connected in the telescopic slot 6, a hole slot is provided on the telescopic rod 7, the hole slot matches the guide rod 8, the guide rod 8 is movably connected to the inner side of the hole slot of the telescopic rod 7, a spring 9 is sleeved on the outer side of the guide rod 8, one end of the spring 9 is fixedly connected to the inner wall of the telescopic slot 6, and the other end of the spring 9 is fixedly connected to the telescopic rod 7. The length of the entire auxiliary connecting rod 3 is changed by moving the telescopic rod 7 in the telescopic slot 6, so as to avoid being restricted by the auxiliary connecting rod 3 when the patient opens his mouth to drive the upper braces 1 and the lower braces 2 to move. The length of the auxiliary connecting rod 3 and the guide rod 8 cooperate with the telescopic slot 6 to guide the moving direction of the telescopic rod 7 to avoid deviation during the movement. When the patient opens his mouth, the upper braces 1 drives the hanging ring 5 to pull the hook 4 to move upward, and the lower braces 2 drives the connecting seat 10 and the auxiliary connecting rod 3 to move downward, thereby pulling the two ends of the spring 9 to make the telescopic rod 7 move in the telescopic slot 6. The spring 9 can play a role in assisting the return. After the telescopic rod 7 moves, the patient will release the force when closing his mouth, and the spring 9 will retract, driving the telescopic rod 7 to move along the guide rod 8 into the telescopic slot 6, thereby avoiding the extended telescopic rod 7 affecting the patient when the patient closes his mouth.

[0027] See also Figure 4-Figure 6In this embodiment, a connecting seat 10 is provided between the auxiliary connecting rod 3 and the lower braces 2. The auxiliary connecting rod 3 is movably connected to the outer side of the connecting seat 10. A rotating groove 13 is provided on the connecting seat 10. A rotating shaft 14 matching the rotating groove 13 is fixedly connected to the auxiliary connecting rod 3. A No. 1 buckle 11 is provided on the rear side of the connecting seat 10. A No. 2 buckle 12 symmetrically connected to the outer side of the lower braces 2 is fixedly provided. The No. 2 buckle 12 matches the No. 1 buckle 11. One end of the auxiliary connecting rod 3 movably connected to the connecting seat 10 is fixed to the lower braces 2 through the connecting seat 10, and the auxiliary connecting rod 3 is fixed to the lower braces 2 through the hook 4 and the hanging ring 5. The other end of the connecting rod 3 is fixed on the upper braces 1 to realize the connection between the upper and lower braces 2. The auxiliary connecting rod 3 is located on the side of the patient's mouth to achieve shielding, which will not affect the aesthetics of the invisible orthodontic correction device of the teeth. The rotating shaft 14 rotates in the rotating groove 13 to change the angle of the auxiliary connecting rod 3, so that it can change the angle of the connecting rod as the person's mouth opens. The connecting seat 10 can be installed on the outside of the lower braces 2 by the mutual engagement of the No. 1 fastener 11 and the No. 2 fastener 12, so that the auxiliary connecting rod 3 movably connected to the connecting seat 10 can be disassembled and assembled, which is convenient for replacing the auxiliary connecting rod 3 and the lower braces 2.

[0028] During the operation, the patient first goes to the dental hospital, and the medical staff automatically generates a model through computer software based on the patient's face and teeth scan, and then makes the upper braces 1 and lower braces 2 according to the model. After the patient connects the No. 1 fastener 11 of the connecting seat 10 with the No. 2 fastener 12 fixedly connected to the lower braces 2, the patient puts on the lower braces 2 first, and then puts on the upper braces 1. Then, the patient reaches out and rotates the auxiliary connecting rod 3, which rotates in the rotating groove 13 through the rotating shaft 14, so that the hook 4 can be hung in the hanging ring 5, realizing the positioning of the auxiliary connecting rod 3, connecting the upper braces 1 and the lower braces 2 together, and changing the contact point of the upper and lower dental arches through the positioning point, thereby providing assistance to the invisible orthodontic correction device and changing the patient's mandibular position;

[0029] When the patient opens his mouth, the upper braces 1 and the lower braces 2 respectively drive the two ends of the auxiliary connecting rod 3 to move. While the auxiliary connecting rod 3 moves in the patient's mouth, the two ends of the spring 9 sleeved on the outside of the guide rod 8 are pulled, and the telescopic rod 7 moves in the telescopic groove 6, changing the position of the auxiliary connecting rod 3. When the patient closes his mouth, without external force pulling, the spring 9 will drive the telescopic rod 7 to retract due to its own elastic force, thereby shortening the auxiliary connecting rod 3.

[0030] Through the above steps, an auxiliary connecting rod 3 for connecting the upper braces 1 and the lower braces 2 is added to the existing invisible orthodontic correction device, and the auxiliary connecting rod 3 is connected to the upper braces 1 and the lower braces 2 through the hook 4 and the hanging ring 5 using the hanging ring 5 fixedly connected to the upper braces 1. This improves the correction force of the invisible orthodontic correction device and solves the problem of poor versatility caused by the weak correction force of the existing invisible orthodontic correction device.

[0031] 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.
