Description

Fully synchronous bracket

Technical Field

The invention relates to the technical field of orthodontic treatment, in particular to a fully synchronous bracket.

Background

Brackets are important components of orthodontic treatment, in the course of conventional orthodontic treatment, an orthodontist affixes the brackets to a patient's teeth and places an archwire in the archwire slots of the brackets, the archwire applying force to the teeth to move the teeth to the correct position.

The brackets do not have specific retention for the archwire and typically use an auxiliary tool such as a ligature wire to tie the tie wings of the bracket so that the archwire is retained within the bracket. In order to facilitate the binding of a ligature wire to a bracket, four outwardly extending ligating wings are typically provided on the bracket body of prior brackets. The bracket is small in size, and the four outward-spread-shaped ligating wings inevitably form sharp convex parts around the bracket body. The bracket is used on teeth, which is easy to cause discomfort of the oral cavity of a user and has poor comfort. In the aspect of resisting food impact, the sharp appearance of the bracket body can not only increase the food impact force and damage teeth, but also the outward-spread type ligation wings are easy to break due to the impact of food, so that the ligation wires cannot be tightened continuously, and the ligation is failed or even falls off.

Disclosure of Invention

In view of the above problems, the invention provides a fully synchronous bracket with a round shape and convenient for ligature of a ligature wire, which is used for orthodontic correction of teeth, has more beautiful shape, more comfortable use and convenient ligature and tightening of the ligature wire, is beneficial to less impact of food on a bracket body and teeth, avoids the broken wings of the ligature wings, can reduce the abrasion of food impact on the teeth and is more beneficial to protecting the health of the teeth.

The technical scheme of the invention is as follows: a full synchronous bracket comprises a bracket body with an arch wire groove, wherein the arch wire groove is transversely arranged in the middle of the bracket body, and the upper side and the lower side of the arch wire groove are respectively provided with an upper tongue-shaped wing and a lower tongue-shaped wing; the two sides of the upper part of the upper tongue-shaped wing are arc-shaped, and the two sides of the lower part of the lower tongue-shaped wing are also arc-shaped. Compared with the traditional bracket body with four ligating wings, the bracket body adopts the upper and lower integrated tongue-shaped wings, namely the upper and lower tongue-shaped wings with arc-shaped corner transition, so that the bracket body is more round in appearance, the sharp bulge of the traditional bracket body is eliminated, the bracket body is more attractive in appearance and more comfortable to use, ligation and tightening of a ligature wire are facilitated, less food can impact the bracket body and teeth, broken wings of the ligating wings are avoided, abrasion of food impact on the teeth can be reduced, and tooth health can be protected.

Preferably, the base of the bracket body is arc-shaped, and arc-shaped transition curved surfaces are arranged on two sides of the base. The improvement of the structure is beneficial to the binding of the ligature wire, the ligature wire can be more tightly bound, and the condition that the ligature wire is loosened is avoided.

Preferably, a positioning midline is arranged on the upper tongue-shaped wing and/or the lower tongue-shaped wing.

Preferably, the upper tongue-shaped wing is further provided with a positioning mark.

Preferably, the left side and the right side of the base of the bracket body are provided with the protruding parts, so that the stability of the base is improved, and the transmission and the expression of torque are facilitated.

Preferably, the contact surface of the base of the bracket body, which is in contact with the ligature wire, is an arc-shaped surface, and arc-shaped transition curved surfaces are arranged on two sides of the base of the bracket body.

Preferably, an inner sinking groove is arranged in the middle of the arch wire groove. The structural design of the inner sinking groove is beneficial to reducing the contact surface between the arch wire groove and the arch wire, thereby reducing the friction.

Preferably, the left and right notch edges of the arch wire groove are provided with arc chamfers, so that the arch wire can be conveniently guided in.

The invention has the beneficial effects that: compared with the traditional bracket body with four ligating wings, the bracket body adopts an upper single wing structure and a lower single wing structure, namely the upper tongue-shaped wing and the lower tongue-shaped wing with arc-shaped corner transition, so that the bracket body is more round in appearance, the sharp bulge of the traditional bracket body is eliminated, the bracket body is more attractive in appearance and more comfortable to use, ligation and tightening of a ligature wire are facilitated, the impact of less food on the bracket body and teeth is facilitated, the broken wings of the ligating wings are avoided, the abrasion of the food impact on the teeth is reduced, and the health of the teeth is more facilitated to be protected.
