Problems solved by technology

[0004] This operation method of rotating from outside to inside requires the patient to keep their mouth wide open at all times during the expansion process, which is difficult and time-consuming to operate, and increases the risk of the patient accidentally sucking the expansion key. Causing the expansion key to break the palatal mucosa
[0005] Based on this, how to improve the unreasonable design of the existing expansion device and improve the convenience and safety of the expansion operation is a technical problem that needs to be solved urgently.

Embodiment 1

[0062] A bow expander includes an adjusting gear 1, a first sliding rack 2, a second sliding rack 3, a first base plate 4 and a second base plate 5; an adjusting groove 11 is opened at the center of the end face of the adjusting gear 1; A sliding rack 2 and a second sliding rack 3 are arranged on both sides of the adjusting gear 1 in parallel with each other, and mesh with the adjusting gear 1 respectively; the first base plate 4 is fixed to one end of the second sliding rack 3 and is connected to the A sliding rack 2 is slidably connected; the second base plate 5 is fixed to one end of the first sliding rack 2 away from the first base plate 4 , and is slidably connected to the other end of the second sliding rack 3 . The expander is provided with a matching expanding wrench. The expanding wrench includes a connecting part 6 and an operating part 7; angle.

[0063] The adjusting gear 1 includes a concentrically arranged central gear 12 and gear baffles 13 fixed on both end fa...

Embodiment 2

[0067] This embodiment is an improvement carried out on the basis of Embodiment 1, and the details are as follows:

[0068] see Figure 7 , On the basis of Example 1, the belt ring and its connecting device are cancelled, the substrates on both sides of the arch expansion device are embedded in the occlusal pad, and the occlusal pad is fixed on the dental arch by the adhesive, so that the force of the substrates away from each other is passed through The occlusal pad is transmitted to the dental arch and further to the maxilla on both sides to achieve the lateral widening of the maxilla.

Embodiment 3

[0070] This embodiment is an improvement carried out on the basis of Embodiment 1, and the details are as follows:

[0071] see Figure 8 , On the basis of Example 1, two round holes are added on each of the two substrates, and the implant nails can be fixed on both sides of the midpalatal suture through the round holes, so that the force of the substrates moving away from each other is transmitted to both sides of the midpalatal suture through the implant nails , to achieve lateral bony widening of the maxilla.

Abstract

The present invention provides an adjustable bow expansion kit and its usage method, the bow expansion kit includes a bow expander and a bow expansion wrench. Among them, the bow expander includes an adjustment gear, a pair of sliding racks and a pair of base plates; an adjustment groove is opened at the center of the end face of the adjustment gear, and a pair of sliding racks are arranged in parallel to mesh with the adjustment gear respectively; The connecting part and the operating part of the angle, the connecting part is provided with a raised part that matches with the adjustment groove, and the expansion wrench is configured to drive the adjustment gear by laterally swinging the operating part when the raised part is engaged in the adjusting groove Rotate to realize the adjustment of the distance between the first base plate and the second base plate. The expansion kit provided by the present invention can prevent the patient from keeping the mouth wide open at all times during the expansion operation, reduces the difficulty of the expansion operation, shortens the adjustment time, and can also prevent the patient from accidentally inhaling the expansion key. safety risks and ensure the personal safety of patients.

Description

technical field [0001] The invention belongs to the technical field of oral medical aids, and in particular relates to an adjustable arch expansion kit and a method for using the same. Background technique [0002] The irregular width of the upper and lower dental arches is one of the common malocclusions in orthodontic treatment. The usual treatment is to expand the maxilla to reconcile the width between the upper and lower jaws. The expansion of the maxilla is realized by the maxillary arch expansion device, that is, the arch expander. The arch expansion device is connected with the maxillary teeth, dental arch or maxillary bone through devices such as belt rings, occlusal pads, and implants, so as to transmit the expansion force to the midpalatal suture. Widening of the maxilla. [0003] The working principle of the expansion device is to increase the width of the expansion device by rotating the rod, and then transmit the generated orthopedic force to the midpalatal su...
