Self-ligating bracket with anti-dislocation slip cover

Abstract

The invention relates to a self-ligating bracket with an anti-dislocation slip cover. The self-ligating bracket comprises a bracket baseplate, a pedestal, a slideway, the slip cover and a neck, wherein the neck is arranged at the upper part of a second sidewall and parallel to the direction of a groove, the slideway is arranged on the part of the pedestal located between the bottom of the groove and the bracket baseplate and is perpendicular to the direction of the groove, the slip cover is a sheet with a U-shaped cross section and comprises a snapping piece, a connecting piece and a sliding piece, the above-mentioned pieces are successively connected, the snapping piece and the connecting piece are respectively positioned at two arms of a U shape, the end of snapping piece can be inserted into the neck, the sliding piece is slidable in the slideway, and the outer rim of the sliding piece is in interference fit with the inner wall of the slideway. According to the invention, since the slideway is arranged on the part of the pedestal located between the bottom of the groove and the bracket baseplate, the slip cover is accordingly designed to be a U-shaped sheet with upper and lower arms, so the slideway and the sliding piece used for spacing and positioning of the slip cover are hidden below the groove; due to protection of the upper part of the pedestal, the slip cover is prevented from accidental dislocation because of frequent touching with a buccal labial surface of the self-ligating bracket in the process of orthodontic treatment of an orthodontic patient, so stable and effective orthodontic operation is effectively guaranteed.

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
