Description

Technical Field

[0001] The utility model relates to the technical field of correction devices, in particular to an oral orthodontic correction device. Background Art

[0002] Orthodontics is the use of various correction devices to adjust the balance and coordination between facial bones, teeth and maxillofacial nerve muscles. In other words, correction is to adjust the abnormal relationship between the upper and lower jaws, between the upper and lower teeth, between the teeth and jaws, and between the nerves and muscles that connect them. When medical personnel perform dental correction on patients, they usually need to use a mouth opener to open the patient's mouth first, and then use the corresponding correction method according to the patient's specific condition;

[0003] As in the prior art, the Chinese patent authorization number is CN202221709005.8, the application date is 2022-07-04, and the name is a utility model patent for an oral orthodontic correction device, which discloses an oral orthodontic correction device, including a base, an arch wire is installed on the inner side of the base, and the arch wire can move and adjust the installed teeth, and an integrated first bracket seat is provided on one side of the front surface of the base, and a pin rod is installed on the inner side of the first bracket seat, and the pin rod is installed by plugging, and the plug-in installed pin rod is convenient for plugging and unplugging adjustment and movement, and is convenient for installation and use. An integrated limit rod is provided at one end of the pin rod, and the surface of the first bracket seat is opened A limiting groove is provided. When the pin rod is locked, the limiting rod on the pin rod can be aligned and snapped into the limiting groove to prevent the pin rod from moving. An integrated second bracket seat is provided on the other side of the front surface of the base. A pin groove is provided on one side of the second bracket seat. One end of the pin rod is aligned with the pin groove. The aligned pin rod and the pin groove are conveniently inserted and locked, which solves the problem that the existing oral orthodontic correction device usually needs to use dental correction brackets during dental correction treatment. When the commonly used brackets are used, they are fixed by ligature wires and rubber rings. Since the rubber rings and ligature wires both have a force on the arch wire, the friction between the arch wire and the bracket is easily increased, which affects the straightening effect and increases the straightening time.
