system for orthodontics

Abstract

The invention relates to a system for adjusting tooth arrangement, a manufacturing method, and a tooth correcting system consisting of a plurality of systems for adjusting tooth arrangement. Each system for adjusting tooth arrangement comprises a first removable instrument and a plurality of middle removable instruments; and the first removable instrument and the middle removable instruments can be combined for use, so that the effects of shortening the correcting cycle, improving compliance of a patient and saving treatment cost can be achieved. The first removable instrument can be a removable appliance or retainer, and the middle removable instrument can high polymer shells; and each high polymer shell has a cavity which has such as a shape that teeth can be accommodated in the cavity and can be elastically moved.

Description

technical field [0001] The present invention relates to the field of orthodontics. Background technique [0002] The traditional method of orthodontics is to have the patient wear so-called "braces". Braces are devices consisting of brackets, archwires, ligatures, and O-rings. In the process of traditional orthodontics, before the braces are fixed on the patient's teeth, the tooth surface is treated with a weak acid, the purpose is to improve the bonding performance of the tooth surface, so that the bracket and the hoop are bonded to the tooth surface. After acidification, the doctor secures the brackets and hoops to the patient's teeth with a suitable bonding material. Do not install the force-applying device—the archwire—until the adhesive is set. [0003] The arch wire is the main force applying device of traditional braces. The arch wire is elastic and fixed on the bracket through the groove on the bracket. The archwire connects the many brackets and constantly appl...

Problems solved by technology

For patients, this traditional orthodontic treatment works well, but there are some problems: doctors fix the brackets completely based on visual perception, and it is difficult to ensure that the position of the brackets is as ideal as expected; the brackets are exposed to the outside , affecting the appearance of the patient; the contact surface between the braces and the teeth is difficult to clean for a long time and lacks effective hygiene measures, which can easily lead to dental caries, oral cavity or periodontal infection; multiple follow-up visits to replace the arch wire or tie rope not only increases the patient's costs and make patients feel uncomfortable

These orthotics often cause dysphonia and foreign body sensation in patients, and it is often difficult for patients to insist on wearing them

However, if the patient cannot cooperate with the treatment and cannot insist on wearing it, the treatment effect will not be guaranteed, and eventually the teeth will rebound / recur to the original position under the orthodontic treatment, which greatly reduces the orthodontic effect of using the movable device
