A self-locking bracket with an anti-dislocation sliding cover

Abstract

The invention relates to a self-locking bracket with a dislocation-preventing sliding cover, which comprises a bracket bottom plate, a base, a slideway, a sliding cover and a card slot. The card slot is arranged on the upper part of the second side wall and is parallel to the groove direction; the slideway is set on the base between the bottom of the groove and the bottom plate of the bracket, and is perpendicular to the direction of the groove; the slide cover is a U-shaped sheet, including sequentially connected cards, connecting pieces and slides. The card, the slide and the slide are respectively located on the two arms of the U shape. The end of the card can be snapped into the card slot, and the slide can slide in the slideway; the outer edge of the slide is an interference fit with the inner wall of the slideway. Since the slideway is arranged on the base between the bottom of the groove and the bottom plate of the bracket, the slide cover is designed as a U-shaped sheet with upper and lower arms, so that the limit and positioning of the slide cover are realized. Both the slideway and the slide sheet are hidden under the groove. Based on the protection of the upper part of the base, the slide cover will not cause accidents due to frequent contact with the lip and buccal surface of the self-locking bracket during the orthodontic treatment process. The situation of dislocation effectively guarantees the stable and effective progress of orthodontic work.

Description

technical field [0001] The invention relates to the field of dental orthodontic instruments, in particular to a self-locking bracket with a dislocation-preventing sliding cover. Background technique [0002] Orthodontic treatment is a highly specialized branch of dentistry, mainly for the correction of teeth, jaws, and facial deformities, and gradually restores the normal occlusal function of patients by fixing orthodontic appliances inside the oral cavity. Brackets are an important part of orthodontic appliances. They are mainly bonded to front teeth, canines, and premolars. Orthodontic treatment guides the misaligned teeth to move to the ideal position by installing the orthodontic arch wire in the groove of the bracket. s position. Traditional brackets are fixed in the groove by ligating wires or elastic rubber rings, but this fixing method has the disadvantages of time-consuming and inconvenient clinical operations, high friction, and poor comfort.

Problems solved by technology

However, in this patent, the sliding groove, positioning groove, locking buckle groove and core sliding cover are all arranged on the top of the bracket ligation wing, so that the core sliding cover is vulnerable to accidental opening by external influences such as patients chewing and brushing teeth, and loses the square wire. The groove controls the arch wire, which in turn affects the therapeutic effect

In addition, an inwardly protruding locking buckle is provided on the end of the side spring bar outside the core sliding cover. During the process of opening or closing the square wire slot, the locking buckle needs to be connected from the bracket ligation wing on the side of the square wire slot. The positioning groove of the bracket moves into the locking buckle groove of the bracket ligation wing on the side of the square wire slot, and when the locking buckle moves to the top of the square wire slot, there is no structural support above the square wire slot, so that the side spring bar returns to loose state, the locking buckle is stuck between the two side walls of the square wire groove, causing the square wire groove to be in a semi-closed state. Slotted Ligating Wings Locking Buckle Slots Very Difficult
