Invisible orthodontic tooth socket, buccal side multi-curved spring matched with invisible orthodontic tooth socket and buccal side multi-curved spring invisible orthodontic appliance with invisible orthodontic tooth socket

Abstract

The invention provides a buccal side multi-curved spring invisible orthodontic appliance which comprises an invisible orthodontic tooth socket and a buccal side multi-curved spring, the invisible orthodontic tooth socket comprises an upper jaw invisible tooth socket and a lower jaw invisible tooth socket, and the buccal side of the upper jaw invisible tooth socket and the buccal side of the lower jaw invisible tooth socket are both provided with a bag-shaped structure; a containing cavity is formed in the bag-shaped structure, the containing cavity penetrates through one side of the bag-shaped structure to form a bag opening, the bag opening of the bag-shaped structure on the upper jaw invisible tooth socket faces the back tooth area, and the bag opening of the bag-shaped structure on the lower jaw invisible tooth socket faces the front tooth area; the two free ends of the buccal side multi-curved-spring are connected with reinforcing blocks, and the reinforcing blocks at the two free ends of the buccal side multi-curved spring are detachably connected with the containing cavity of the upper jaw invisible tooth socket bag-shaped structure and the containing cavity of the lower jaw invisible tooth socket bag-shaped structure in an inserted mode through the bag openings respectively. The buccal side multi-curved spring and the invisible orthodontic tooth socket can be combined together to realize stress application for orthodontic treatment. The invention also provides the used invisible orthodontic tooth socket and the buccal side multi-curved spring matched with the invisible orthodontic tooth socket.

Description

technical field [0001] The invention relates to the field of orthodontics, in particular to an invisible orthodontic brace, a buccal multi-curved spring matched with it, and a buccal multi-curved spring invisible aligner with the same. Background technique [0002] Angle's class Ⅲ malocclusion is one of the common malocclusions in clinical oral cavity, and it has a high incidence in the Asian population. Angle's class III malocclusions are usually due to underdevelopment of the maxilla or overdevelopment of the mandible, or a combination of the two. Due to the abnormal development of the patient's appearance, occlusion, and speech function, the patient has a serious physical and psychological burden. In recent years, there has been a method of using buccal multi-flex spring appliances for intermaxillary reciprocal anchorage for Angle's class III malocclusion patients. The buccal multi-curved spring appliance uses the multi-curved springs on both sides to connect the upper ...

AI Technical Summary

Problems solved by technology

Then, bending the horizontal curve leads to complex structure of the buccal multi-curved spring appliance. Usually, the production time of each appliance is 3-4 hours, which is difficult to make and takes a long time to make, and it is difficult to be popularized clinically.

At the same time, although the vertical thrust given to the upper and lower jaw bases by horizontal bending can strengthen the retention of the upper and lower jaw bases, but the horizontal curvature will bring a larger vertical thrust to the upper and lower jaw bases, and the upper jaw can be pushed forward. In the process of mandibular retraction, the excessive vertical thrust exerted by the horizontal curve can easily lead to unnecessary movement of the teeth

In addition, the upper and lower jaw bases are only a retainer, and do not have the function of aligning teeth with invisible orthodontics

[0004] (2) The buccal multi-curved spring appliance is usually made of a stainless steel wire, which is embedded in the upper and lower jaw bases during use, and it is prone to occur in the stress concentration area during the correction (the lateral multi-curved spring appliance and the upper The area where the mandibular base contacts) breaks

Although the use of invisible braces without brackets overcomes the weaknesses of traditional fixed orthodontics in terms of treatment duration and comfort, it will increase the difficulty of making invisible braces without brackets, and there are still disadvantages of low night-time treatment efficiency: patients at night The relaxation of the muscles around the mouth during sleep leads to the disengagement of the upper and lower jaws. At this time, even if you wear an orthotic, it will not work; and the secretion of growth hormone is strong during sleep, which is the golden time to guide the growth and development of the jaws. These limitations limit the The scope of clinical application and correction efficiency of existing clear orthodontic devices

For example, a Chinese utility model with application number 201320028895.0 discloses a mandibular guide and a Chinese utility model with application number 201720697007.2 discloses an invisible orthodontic device. However, there is still the defect of low efficiency of leading the mandible at night. This is because the muscles around the mouth of the patient will relax during sleep at night, which will cause the upper and lower jaws to disengage. play a role; and growth hormone is strongly secreted during sleep, which is the golden time to guide the growth and development of the jaw bone. These deficiencies limit the clinical application range and correction efficiency of the existing invisible orthodontic devices
