Individual tongue side self-locking appliance

Abstract

The invention discloses an individual tongue side self-locking appliance which comprises a plurality of tongue side self-locking support grooves and an arch wire which is used for serially connecting the tongue side self-locking support grooves, wherein each tongue side self-locking support groove comprises a bottom plate which is fitted for a corresponding tooth position tongue side and a support groove body which is fixedly connected with the bottom plate; a locking cover is hinged on the support groove body; the locking cover is elastically hinged on the support groove body; and a locking groove for clamping the tail end of the locking cover is formed in the support groove body. According to the individual tongue side self-locking appliance, the plurality of tongue side self-locking support grooves are serially connected together by using the arch wire, the bottom plates at the bottoms of the support groove bodies are made of a flexible metal, and the locking cover is clamped into the locking groove in the serially connecting process, so that the self-locking of the arch wire in each support groove body position is realized, each support groove body position of the self-locking appliance has better freedom, the comfort degree of patients is effectively improved, and at the same time the clinical operation of doctors is facilitated, as a result, the individual tongue side self-locking appliance is applied to the field of tooth appliances.

Description

technical field [0001] The invention relates to the field of dental appliances, in particular to a lingual self-locking appliance. Background technique [0002] With the development of orthodontic technology, lingual orthodontics is considered by more and more orthodontists as the development direction of orthodontic technology. In current orthodontic treatment, ordinary brackets need to use ligature wires or rubber rings to maintain the contact between the archwires and the brackets, which will generate greater pressure on the archwires and reduce the friction between the archwires and the grooves. The increase hinders the normal movement of the arch wire and affects the effect of orthodontic treatment. At the same time, ligature wire ligation or rubber band ligation, especially in the narrow space of the tongue side, is difficult to operate, and the doctor needs to spend more time.

AI Technical Summary

Problems solved by technology

In current orthodontic treatment, ordinary brackets need to use ligature wires or rubber rings to maintain the contact between the archwires and the brackets, which will generate greater pressure on the archwires and reduce the friction between the archwires and the grooves. Increased, which hinders the normal movement of the arch wire and affects the effect of orthodontic treatment

At the same time, ligature wire ligation or rubber band ligation, especially in the narrow space on the lingual side, is more difficult to operate, and the doctor needs to spend more time

[0003] There are three main types of lingual self-ligating brackets currently on the market, one is a simple self-ligating bracket with two-dimensional self-locking function, which has the advantages of small size and thin thickness, but because it cannot achieve three-dimensional control of teeth , so it can only treat simple malocclusion cases; the other is a lingual bracket similar to a labial bracket. Therefore, the overall thickness and volume of the bracket are still very large, which seriously affects the comfort of the patient; in addition, a lingual self-ligating bracket with a personalized bottom plate has recently appeared, but the self-locking bracket body is still mass-produced , and then welded on the personalized bottom plate, therefore, the problem of bracket thickness is not completely solved

[0004] In addition, the above brackets did not fully consider the difference between the force on the lingual side of the archwire and the force on the labial side, and the difference in the correction methods during the correction of the labial and lingual side. The self-locking structure generally adopts the same method as the labial side.
