Description

Multifunctional straight wire bow bracket

Technical Field

The utility model belongs to the field of medical appliances, relates to an orthodontic component, and in particular relates to a multifunctional straight wire bracket used for fixing an appliance.

Background

Today, in orthodontic, the commonly used fixed correction techniques are divided into two main systems: a straight wire arch correction system and a Begg correction system. The straight wire arch correction system is also called as an square wire arch correction system, and can enable the movement of the teeth in the near-far direction (the front-back direction) (the horizontal direction) to be integral movement, so that the straight wire arch technology can accurately control the teeth, but the tooth movement speed is low, and the correction force is larger. The begg correction system can enable the teeth to rapidly move in an inclined mode in the horizontal direction, and usually the teeth crown is moved in an inclined mode firstly, then the teeth roots are moved in an inclined mode, the tooth correction is performed in a crossed mode, and finally the purpose of correcting the teeth is achieved. The begg correction system has the advantages of light force and high speed for moving teeth, and can obviously shorten the treatment course, but has the defects of complex operation of post positive axis (righting the tooth root, adjusting the mesial-distal direction of the teeth) and root control (adjusting the labial-lingual direction position of the tooth root) and the like.

Whether a straight wire arch correction system or a Begg correction system, the correction device mainly comprises a bracket, a belt ring, correction archwires, accessories and the like, wherein the length from a cutting end of a dental crown to a gingival end is limited, the whole length of the bracket cannot be excessively long (if the structural design of two grooves is adopted, the whole length of the bracket can be increased), otherwise, the excessively long bracket is easy to stimulate gums for some teeth, particularly rear teeth, or the mandibular bracket is easy to be bitten by maxillary teeth.

At present, the limitation of bracket length is limited, and current bracket all adopts single groove structure, either does whole removal, or does tilting movement, and the function is more single, is difficult to accomplish that a bracket possesses two kinds of tooth simultaneously and rectifies the removal form.

Disclosure of Invention

The utility model aims to provide a multifunctional straight wire arch bracket, which adopts a groove combined with parallel pipes design, utilizes an orthodontic wire to enable teeth to perform inclined movement or integral movement according to actual needs, organically combines a straight wire arch correcting technology (integral movement of the teeth) with a Begg correcting technology (inclined movement of the teeth), realizes reinforcement of anchorage, more effective positive axis, root control and the like, and improves the efficiency and effect of orthodontic correction.

In the dental industry, a portion near the cusp direction is generally defined as a tangential direction (a fitting direction) and a portion near the gum direction is generally defined as a gingival direction, depending on the orientation of the tooth. Similarly, in the orthodontic industry, after a bracket is bonded to a tooth surface, a portion near the cusp direction is called a tangential direction (a fitting direction), and a portion near the gingival direction is called a gingival direction.
