Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dental brackets, in particular to an orthodontic bracket. Background Art
[0002] When a patient's crooked teeth need to be corrected, dental orthodontic brackets are needed. The brackets are fixed to the patient's teeth by bonding. The positioning midline in the middle of the bracket makes it easy to position the bracket in the middle of the tooth. The brackets also make it easy to position the arch wire and the fixing clip, making it convenient to correct the patient's teeth.
[0003] The existing orthodontic bracket includes a base for bonding the bracket to the tooth. The positioning center line in the middle of the bracket is used to facilitate positioning of the bracket to avoid the bracket from tilting. The placement groove inside the bracket is used to facilitate placement of the arch wire, and the arch wire is fixed in the placement groove by a fixing clip to ensure that the arch wire is stable and will not loosen.
[0004] However, in the implementation of relevant technologies, it was found that the existing orthodontic brackets have the following problems: there is a certain gap between the arch wire and the placement slot. After the patient has a meal, food residues are easily accumulated in the gap between the placement slot and the arch wire. Since the arch wire is fixed in the placement slot, it is not easy for a toothbrush to brush the food residues in the gap between the arch wire and the placement slot when brushing teeth, which can easily lead to bacteria breeding in the gap between the arch wire and the placement slot, increasing the risk of tooth decay for patients. In view of this, a dental orthodontic bracket is provided to overcome the above-mentioned defects. Utility Model Content
