CN201079455Y - Arch wire for teeth orthodontic device - Google Patents

Abstract

The utility model relates to an arch wire of a tooth orthodontic appliance, which comprises a noncircular stainless steel arch wire 1, omega curves 2 with a diameter between 2 to 4 mm are bent on the position corresponding to the arch wire 1 between two teeth which begins with a lateral incisor and ends with a second molar; wherein, the number of the omega curves 2 is between over one pair and below five pairs. One side of a mouth part of each omega curve 2 is a distal part 3, and the other corresponding side is a mesial part 4. Because the utility model effectively shortens the size of a bent curve of the arch wire, so patients feel more comfortable than a traditional straightener. Food debris is not easy to remain on the arch wire, which is favorable to oral hygiene maintenance and oral health holding. The mucous membrane of the oral lip and cheek is not easy to be stimulated, so the possibility of the occurrence of mucous membrane ulcer is greatly reduced. The omega curve prolongs the length of the arch thread, which enables the arch thread to generate a softer orthodontic force and fewer side effects. The bending of the omega curve which assists orthodontic treatment is simpler than a traditional L-shaped curve, and the operating time of a clinician is saved.

Description

A kind of arch wire of orthodontic device

technical field

The utility model belongs to the field of orthodontic appliances, in particular to an arch wire of an orthodontic appliance.

Background technique

Dental malocclusion refers to the deformity of teeth, jaw and craniofacial caused by congenital genetic factors or acquired environmental factors, such as diseases, bad oral habits, abnormal tooth replacement, etc. during the process of human growth and development, such as tooth arrangement Unevenness, abnormal jaw relationship between the upper and lower dental arches, abnormal size, shape, and position of the jaws, etc. It not only affects the beauty of the face, but more importantly affects people's normal chewing and pronunciation functions. At present, the arch wire of the orthodontic device widely used clinically is from the lateral incisors to the middle, and a horizontal curve, that is, an L-shaped curve, is bent between each pair of adjacent teeth. Each L-shaped curve consists of two parts, vertical and horizontal. The horizontal and vertical curves of each L-shaped curve can control the horizontal and vertical positions of the teeth respectively. Due to the existence of multiple curves, the deformation rate of the arch wire is reduced, and the elasticity of the arch wire is increased, making the correction The force is soft and long-lasting. However, due to the existence of complex L-shaped curves, it often brings difficulties to the maintenance of oral hygiene. Food residues are often hooked on the arch wire, which is difficult to clean and easily induces bad breath, gingivitis and other diseases; complex The L-shaped curve is easy to irritate the patient's lip and buccal mucosa, causing mucosal ulcers, and even the stimulated mucosa grows into the L-shaped curve, which brings great pain to the patient; in addition, the L-shaped curve is complicated to make and costs A large amount of operating time for clinicians and low efficiency.

Contents of the invention

In order to solve the above-mentioned deficiencies in the prior art, the utility model provides an archwire for an orthodontic device, which has the advantages of comfort, sanitation, softer orthodontic force, short clinical operation time, and less pain for patients.

In order to achieve the above purpose, the technical solution adopted by the utility model is: an arch wire of an orthodontic device, including an arch wire 1, the corresponding arch wire between the two teeth from the lateral incisor to the end of the second molar 1. There are more than 1 pair and 5 pairs of omega curves 2 with a diameter of 2 to 4 mm on the upper curve.

Because the utility model effectively reduces the bending size of the arch wire, after wearing it in the mouth, the patient feels more comfortable than the traditional method, which is beneficial to cooperate with the treatment; food residues are not easy to remain on the arch wire 1, which is beneficial to the maintenance and maintenance of oral hygiene. Oral health maintenance; small omega song 2 is not easy to irritate oral buccal mucosa, so the possibility of mucosal ulcers is greatly reduced; the existence of omega song 2 prolongs the length of arch wire 1, making the The corrective force is softer and has fewer side effects. Omega Curve 2 can be attached to various tractions to assist orthodontic treatment. The bending of Omega Curve 2 is simpler than the traditional L-shaped curve, which saves the operation time of clinicians.

Description of drawings

Accompanying drawing is the structural principle diagram of the utility model.

Detailed ways

The structural principle and working principle of the utility model are further described in detail below in conjunction with the accompanying drawings.

Referring to the accompanying drawings, the utility model includes a non-circular stainless steel arch wire 1, and the corresponding arch wire 1 between the two teeth from the lateral incisor to the end of the second molar is bent with a diameter of more than 1 pair and less than 5 pairs. Omega 2 is 2 to 4 mm. One side of the mouth of Omega 2 is distal 3, and the other side is mesial 4.

The arch wire 1 between every two omega curves 2 of the utility model is fixed on the teeth, and the arch wire 1 is square, so the adjustment of the arch wire 1 can move the teeth in three-dimensional directions. Adjusting the inclination of the distal 3 and mesial 4 of the Omega Curve 2 can change the curvature of the arch wire 1, thereby loading the force on the teeth. When correcting malocclusion, the Omega Curve 2 can be hung with various rubbers Circle, assisted orthodontic treatment.
