Reasonable arrangement inducing device for teeth of children and manufacturing method thereof

Abstract

The invention relates to a reasonable arrangement inducing device for teeth of children and a manufacturing method thereof. The device is characterized by consisting of an arc-shaped groove body which is sleeved on the teeth; the shape, the size and the spatial arrangement position of the internal of the arc-shaped groove body are different from those of the teeth to be induced so that certain induction force to the teeth to be induced can be generated on the inner surface of the arc-shaped groove body along any direction; therefore, the teeth are induced to be arranged along a target direction reasonably. The device aims to overcome the defects of conventional dentofacial deformity correctors, tooth positioners and related tooth induction methods, and fulfills the aim of inducing the reasonable arrangement of the teeth of the children individually and accurately according to special situations of the teeth of the children.

Description

technical field [0001] The invention relates to a device for inducing rational arrangement of children's teeth and a manufacturing method thereof. Background technique [0002] Medically, people's jaws are forward-turned, retracted, or teeth are not aligned. This phenomenon is called dento-jaw deformity. Dental deformities often lead to incomplete brushing. These parts will leave food residues, inflame the gums, cause caries (tooth decay) and periodontitis, etc., affecting oral health. At the same time, dental and jaw deformities also seriously affect social interaction and work, especially adolescents and children, who often become inferior because of being ridiculed by classmates or friends, which affects children's mental health. According to the survey conducted by the Chinese Stomatological Association, the prevalence rate of dental and jaw deformities in children in my country is 51.84% in the primary dentition period, 71.21% in the replacement dentition period, and 7...

AI Technical Summary

Problems solved by technology

[0006] 2. The force distribution of teeth and jaws is not easy to control

Since the contact area between the metal support and the teeth is limited and the position cannot be adjusted, it can only ensure that the teeth and alveolar bone are subjected to the force tending to the standard arched position, but the biomechanical rationality of the force distribution cannot be guaranteed;

[0007] 3. Since the fixed orthodontic appliance needs to be fixed on the tooth surface, wearing it for a long time will cause damage to the tooth body and periodontal tissue;

[0008] 4. Orthodontic appliances affect the appearance

At the same time, when the existing invisible aligners are applied to children, they can cover the teeth very well because of their personalized features, but this also hinders the rational arrangement of the deciduous teeth, and often causes correction due to tooth loss during the tooth replacement period. Instable device positioning and other problems seriously affect the treatment effect
