Description

Orthodontic device

Technical Field

The invention relates to the technical field of dental equipment, in particular to a tooth straightening device.

Technical Field

Orthodontic treatment generally refers to the treatment of irregular tooth alignment, abnormal tooth morphology, and abnormal tooth shade by oral techniques. There are various methods for tooth correction, such as resin veneering, porcelain teeth, orthodontics, etc., according to the actual condition of individual teeth, the kind of dentognathic deformity, etc.

Dental misalignment is medically known as a malocclusion (malocclusal) deformity. It is the deformity of teeth, (occlusal), jaw and face caused by some factors such as heredity, disease, endocrine disturbance, malnutrition, bad habit of oral cavity, tooth replacement disturbance, etc. in the growth and development process of children and teenagers. Its treatment is medically known as correction. Correction methods vary depending on the cause of the dental disorder, the age of the patient, the type and degree of malocclusion, and the like.

The teeth are uneven and the weight is light. The mild people have no great obstruction to the beauty and the oral function, and the severe people bring different harms.

First, the development of the maxillofacial area is affected. For example, in childhood, there are malocclusion (zygosis) which affect development, such as the anterior retroodontal (zygosis), commonly known as "ground loaf", which is a sickle-shaped face with increasing age and increasing severity.

The teeth are not even, food residues are easy to remain on the tooth surface, and dental caries and periodontal inflammation are caused. Some serious teeth disorder, such as teeth not biting together, jaw deviation, etc., can reduce chewing function and affect speaking and speaking pronunciation.

Serious teeth disorder will undoubtedly cause facial deformity and affect the beauty. In the current society, the system not only influences occupational selection and social interaction, but also brings psychological pressure and thought burden to patients. Meanwhile, the reduction of the chewing function can cause dyspepsia and gastrointestinal diseases, which affect the health of the whole body.

With the progress of medicine and the increasing demand of people for appearance, many technical methods and special equipment for tooth straightening appear, and tooth straightening generally refers to a treatment process for correcting the irregular arrangement of teeth, abnormal tooth morphology and abnormal tooth color by an oral technical means. There are various methods for tooth correction, such as resin veneering, porcelain teeth, orthodontics, etc., according to the actual condition of individual teeth, the kind of dentognathic deformity, etc.

The following is a document of retrieved related orthodontic methods or devices:

patent 1: orthodontic devices; application No.: 201080045963.3, respectively; application date: 2010-08-11; the applicant: university of new york; and (3) abstract: the present invention provides a method of moving teeth to a desired position in a patient's mouth using orthodontics comprising perforating tissue in the oral cavity sufficient to induce an inflammatory response. The perforations may be made in any area of the maxilla or mandible, and any number of perforations may be made, preferably 0.5 to 1.5mm in diameter, and preferably 1 to 3mm deep. The present invention also provides a device for providing perforations that can be used with a slow-rotating instrument or a manual driver.

Patent 2: orthodontic devices and methods; application No.: 201710216415.6, respectively; application date: 2017-04-05; the applicant: harbin Junyan electronic technology, Inc.; and (3) abstract: the invention provides a tooth correcting device, and belongs to the technical field of dental medical treatment. In the tooth correcting device, a first base is used for being bonded on teeth to be corrected, and a second base and a third base are respectively used for being bonded on two adjacent teeth on the left and the right of the teeth to be corrected. An arch wire groove is formed in the first base, and the first dental arch wire penetrates through the arch wire groove. One end of the first dental arch wire is connected with the first correcting block, and the other end of the first dental arch wire is connected with the second correcting block. The first straightening block and the second straightening block are respectively positioned at the left side and the right side of the tooth to be straightened. The first correcting block is connected with the second base through a first spring wire. The second correcting block is connected with the third base through a second spring wire. The first spring wire and the second spring wire are pre-deformed and used for driving the first base to move through the first correcting block and the second correcting block so as to correct the teeth to be corrected. The orthodontic device is simple in structure and less in uncomfortable feeling when being worn by a patient.

Patent 3: an orthodontic device; application No.: 200780033326.2; application date: 2007-09-07; the applicant: radix Cynanchi Paniculati; and (3) abstract: the present invention relates to an orthodontic device and an orthodontic method which can prevent orthodontic treatment from being performed obliquely when teeth are aligned. The orthodontic device includes: a tooth attachment unit attached to an orthodontic tooth object; and a hook member provided on the tooth attachment unit and having a traction unit connection part for orthodontic treatment, the traction unit connection part being located in the vicinity of a center of resistance (c.r) of the tooth. Further, the orthodontic device includes a tooth attachment unit and a hook member provided on the tooth attachment unit and having a traction unit connection part for orthodontic treatment, the traction unit connection part being located at least in the vicinity of a gum. According to the present invention, since the bracket or button-type tooth attachment unit is substantially horizontal with respect to the traction line of the traction unit connected to the tooth attachment unit, orthodontic treatment can be effectively performed without generating a skew phenomenon in which the teeth and the roots of the teeth are inclined.

As can be seen from the above documents, the current mainstream orthodontic methods all use hooks attached to teeth, and a single tooth as an equipment unit, and each unit is connected through a dental arch and the like, so as to apply force to shift and align the single tooth to a central position, and such methods have the defects of extremely high technical requirements on professionals, and if a large deviation occurs in the installation process, the traction direction of each tooth cannot be guaranteed to be kept consistent and level, and the tooth can be inclined or even damaged; and the force of each tooth cannot be uneven, and the teeth usually move in turn in order and cannot move integrally at the same time.
