Deciduous tooth interval loss space restoring and maintaining method

Abstract

The invention discloses a deciduous tooth interval loss space restoring and maintaining method which is characterized by being realized by designing a deciduous tooth interval loss space restoring and maintaining device. The device mainly comprises a retention ring, a chute and a main arch wire, wherein the chute is fixedly connected with the outer side surface of the retention ring; a perforation matched with the outline of the main arch wire is formed in the chute; a retention hook is arranged on a side wall at the front end of the chute; the main arch wire is sequentially composed of a movable rod, a first U-shaped bend, a longitudinal connecting rod, a second U-shaped cheek bend, a front stop lever, a second U-shaped tongue bend and a rear stop lever; the first U-shaped bend, the second U-shaped cheek bend and the second U-shaped tongue bend have vertically downward bend bottoms and are perpendicular to the longitudinal connecting rod, the front stop lever and the rear stop lever; the movable rod at the rear end of the first U-shaped bend penetrates through the perforation in the chute and can slide back and forth in the perforation; a transverse rod is detachably connected to the longitudinal connecting rod; and the transverse rod, the front stop lever and the rear stop lever are parallel to one another and are all transversely arranged. The device is reasonable in design, simple in structure and convenient to use, and the method has high popularization values on child tooth loss space maintenance and restoration.

Description

technical field [0001] The invention relates to the field of oral medical devices, in particular to a method for restoring and maintaining gaps between missing deciduous teeth. Background technique [0002] Deciduous tooth caries is a common and frequently-occurring disease in children's teeth. Some scholars have investigated and analyzed that the rate of deciduous teeth caries in preschool children is as high as 75.3%. Most children have multiple carious teeth in their mouths at the same time. Those with severe caries may develop periapical abscess, alveolar abscess, etc., which must be extracted in the end. This is the main cause of premature loss of deciduous teeth. Secondly, deciduous tooth trauma is also a common cause of premature loss of deciduous teeth. . Deciduous teeth fall out prematurely due to inflammation, dental caries, trauma and other reasons. If the gaps are not maintained in time, the gaps between missing teeth will be lost rapidly. Misplaced eruption or...

AI Technical Summary

Problems solved by technology

The space maintainers commonly used in clinical practice cannot meet the complex situation of deciduous tooth loss

On the whole, the currently commonly used methods have the following clinical defects: (1) It is mainly used to maintain the gap after the premature loss of deciduous molars, or to expand the gap in a small amount. When the gap is reduced to more than 1mm, the space maintainer is commonly used. The gap cannot be expanded, and the adjacent teeth that have moved forward cannot return to the original position, which further leads to the occurrence of malocclusion of the matching teeth

(2) Even if the force can be adjusted slightly, the orthodontic force cannot be controlled, and the space maintenance is used in the mixed dentition stage of children, and the force must be light, usually about 60 grams

(3) After the deciduous molars are missing, the adjacent teeth tend to move mesially and obliquely. Even if the ordinary space maintainer can be slightly adjusted with force, the molars will go straight back, unable to complete the distal inclination and then upright

(4) The ordinary fine-tuning space maintainer has the power to directly expand the gap after it is brought into the mouth, and it cannot be taken out and adjusted after it is worn in and bonded. Children, as a special group, have immature minds and are likely to cause discomfort in children. Let the child get used to the retainer first, and then apply force

(5) For the cases of missing space between multiple deciduous teeth, it is impossible to divide into blocks, and finely adjust the force according to the specific situation of space loss
