Technical Field

The invention relates to the technical field of orthodontic appliances, in particular to an appliance for tooth orthodontics.

Background

Orthodontics means correcting teeth, relieving malocclusion and malformation, and orthodontics mainly adjusts coordination among nerves and muscles of facial bones, teeth and maxillofacial parts through various correction devices, namely, adjusts abnormal relationships among upper and lower jawbones, between upper and lower teeth, between teeth and jawbones and between nerves and muscles connecting the teeth and the jawbones, and the final correction aim is to achieve balance, stability and beauty of the oromandibular system. Orthodontic appliances of present mainly used include bracket, buccal surface pipe etc. and wherein the bracket is the fixed important part of correcting the technique, and the arch wire is through holding in the palm the groove and exert the power of correcting to the tooth, and the main effect of holding in the palm the groove lies in fixed arch wire to make the arch wire exert better and correct the power, in order to reach the purpose of just abnormal correction. Current self-ligating brackets generally include a bracket body and a removable cover, insert or clamp removably attached to the bracket body for opening and closing an archwire slot for receiving an archwire.

Patent CN201380070480.2 discloses a self ligating orthodontic bracket with a sliding cover comprising a body and a ligating archwire cover having a centrally disposed, forwardly extending locking member containing a flexible locking tab adapted to effect closing and opening of the archwire cover as the archwire cover moves from an open position toward a closed position and the locking structure mates with a protuberance on the body. According to the technical scheme, the flexible locking joint is the elastic joint, the arch wire cover needs to be repeatedly rubbed with the bump on the main body when being opened and closed, the problem that the wear-resisting property of elastic materials is poor generally exists, after the arch wire cover is opened and closed for multiple times, the locking is not tight easily, and the problem that the arch wire cover is automatically opened easily is solved.

Detailed Description

Unless otherwise indicated, in the following structural description, reference to the tooth is required to describe the orthodontic bracket, and with particular reference to fig. 1, terms such as labial, lingual, mesial, distal, occlusal, and gingival, as used herein to describe orthodontic brackets are reference frames for the corresponding tooth. However, embodiments of the invention are not limited to the chosen frame of reference and the terms described, as orthodontic brackets may be used with other teeth and other orientations within the oral cavity. For example, orthodontic brackets may also be used bonded to the lingual surfaces of teeth and are within the scope of the invention. Those skilled in the art will appreciate that when there are variations in the reference frame, the descriptive terms used herein may not be directly applicable. However, embodiments of the invention are intended to be independent of position and orientation within the oral cavity and the relative terms used to describe the embodiments are merely intended to provide an unambiguous explanation of the embodiments in the drawings. Likewise, the relative terms labial, lingual, mesial, distal, occlusal and gingival are in no way intended to limit the invention to a particular position or orientation.

It is to be noted that the relative terms labial, lingual, mesial, distal, jaw plane and jaw-gum are the terms of art for orthodontic treatment. Taking the mandibular teeth as an example, the surface of the orthodontic bracket may be roughly divided into six planes. The face facing the lip is the labial side face of the orthodontic bracket, the face facing the tongue is the lingual side face of the orthodontic bracket, the labial side face is opposite to the lingual side face, and the direction formed by the labial side face and the lingual side face is also called the labial-lingual direction. The surface facing the occlusion of the upper jaw teeth is the occlusal surface of an orthodontic bracket, and can also be called as a jaw plane and a jaw end surface; the surface of the gum tissue facing the bonded teeth is the gum end surface of the orthodontic bracket; the direction in which the occlusal surface and the gingival surface form is also called the gingival jaw direction. The face of the tooth facing the midline of the tooth is the mesial face, the face opposite the mesial face is called the distal face, and the direction in which the mesial and distal faces are formed is called the mesial-distal direction.

And in the description of directions, such as the labial and lingual directions, it is generally referred to as bi-directional. For example, the lip-tongue direction refers to a single direction, i.e., a direction from the labial side to the lingual side, and whether or not a dash line is added is used as a distinction.

The axis inclination marking line refers to an inclined line which is arranged on the orthodontic bracket and has the same angle with the bracket axis inclination angle, and is used for more accurate positioning when a doctor uses the bracket to be bonded to a tooth surface.

Furthermore, the components and spaces described below are also described with reference to the reference system of the mandibular teeth, such as the gingival direction, jaw face, etc. of a component, but without limitation to the component and space.
