Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a torque sliding straight wire bow support groove. Background Technology

[0002] Brackets are a crucial component of fixed orthodontic techniques. They are directly bonded to the tooth crown surface using adhesive, and the archwire applies various types of corrective forces to the teeth through the brackets. Brackets are made of stainless steel, bioceramics, or composite resin, and their primary function is to secure the archwire, allowing it to function more effectively and transmit corrective forces. This controls the three-dimensional movement of the teeth, achieving the goal of orthodontic treatment.

[0003] Brackets generally consist of a groove, bracket wings, and a base. The groove opens horizontally towards the labial and buccal surfaces, facilitating the smooth insertion of the archwire from the labial and buccal surfaces for applying force. The bracket wings facilitate the ligation and fixation of the archwire, and hooks can be attached to the wings for traction. According to the shape of the bracket wings, they can be divided into single-wing, double-wing, and triple-wing types. The base shape is mainly designed to enhance the adhesion to the tooth surface. The shape of the bracket base surface is adapted to the shape of the labial and buccal surfaces of each tooth, and it has a metal mesh or an etched base plate. The bracket is firmly bonded to the tooth surface by adhesive. Straight wire brackets are also a type of bracket, but they still have the following drawbacks that need to be addressed: food friction during chewing in the mouth can easily cause the self-ligating components to loosen, resulting in the orthodontic effect not meeting expectations.
