Description

Orthodontic gum anti-pressing structure

Technical Field

The utility model belongs to the technical field of appliances, and particularly relates to an orthodontic gingival compression-preventing structure.

Background

Orthodontic brackets are an instrument used in orthodontic treatment that functions to gradually move teeth to the correct position so that the teeth are aligned and occluded properly to improve oral health and appearance, and to facilitate a dentist to precisely control the speed and direction of movement of the teeth, thereby achieving the best orthodontic effect. In addition, the orthodontic bracket has high adhesiveness, can be stably fixed on the tooth surface for a long time, and reduces discomfort and treatment cycle of a patient. Orthodontic brackets are commonly used to close the maxillary gap, and in clinical treatment, the prior art uses elastic chain loops to hang over the buccal tube of the first molar of the upper jaw and over the towing hook between the maxillary side incisors and the maxillary cuspids. The above treatment regimen has the following problems:

because the cusp position is in the corner of whole dental arch, more salient, so, the gum in the cusp distance is oppressed easily to the chain circle, and for a long time can lead to patient's pain, and the gum injury reddish swelling is inflamed, and the gum is wrapped by the gum in the indentation of chain circle, and the painful bleeding of gum when the chain circle is changed. Therefore, some doctors clinically use long traction hooks to be placed on the long-cuspid middle arch wire to block the chain ring from pressing the gum, but the blocking part is often positioned at the far end of the long traction hooks, so that the force arm is too long, and the traction hooks can not block the chain ring from being pressed into the gum instead.

Secondly, when the gap is closed by adduction, the dental root of the maxillary cusp props against the buccal cortex of the alveolar bone, which easily causes the problems of slow gap closing, loss of anchorage and root absorption.

Accordingly, the present application has been further designed and developed based on some of the above prior art.
