Self-locking bracket with sliding cover

Abstract

The invention relates to a self-locking bracket with a sliding cover. The self-locking bracket comprises a base and the sliding cover, wherein one part, which is positioned on one side of a groove, of the base serves as a first base, and the other part, which is positioned on the other side of the groove, of the base serves as a second base; the upper part of the first base is provided with a first slide way; the upper part of the second base is provided with a second slide way; the first slide way and the second slide way form a channel in which the sliding cover slides; the sliding cover comprises one end in the first slide way and the other end which can enter the second slide way; a limit groove is arranged in the middle part of the sliding cover along the sliding direction; and one end of a banking pin penetrates through the limit groove, and the other end of the banking pin is arranged on the inner wall of the first slide way. As the channel jointly formed by the first slide way and the second slide way limits the upper, lower, left and right movement range of the sliding cover, and the limit groove and the banking pin are matched with each other to limit the front and back movement range of the sliding cover, the sliding cover is effectively limited to move in six directions and can not accidentally fall off when moving and being worn, thereby effectively ensuring the stable and effective operation of orthodontic treatment.

Description

technical field [0001] The invention relates to the field of dental orthodontic instruments, in particular to a self-locking bracket with a 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. [0003] 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. In recent years, the emergence of ...

AI Technical Summary

Problems solved by technology

Since one end of the sliding locking piece in this patent is covered by the chute on one side of the groove, the position limit in the vertical direction is realized, and one end of the locking hook is arranged on the step surface on the other side of the groove, and in the vertical direction No limit measures are taken on the surface, so under the action of external force (such as being pushed away by the arch wire in the groove), one end of the lock hook is turned up to make the groove open accidentally, and the arch wire breaks away from the restriction of the groove

Secondly, the patent does not take measures to restrict the sliding of the sliding locking piece to the outside in the chute, and the sliding locking piece slips from the chute under the action of external force (such as a patient brushing his teeth with a strong force or a doctor’s careless operation, etc.) Retirement of lock brackets

In addition, because in the process of opening and closing the groove, the lock hook needs to be separated in the opposite direction under the action of an external force in the opposite direction in the horizontal direction, so that it can be snapped into or out of the semicircular lock groove. It is very inconvenient to exert external force in the horizontal direction on such miniature components, which increases the difficulty of clinical operation
