Induction appliance with adjustable rear end, correction set and correction system

Abstract

The invention provides an induction appliance with an adjustable rear end, an appliance set and an appliance system.The induction appliance with the adjustable rear end comprises an appliance front body and an appliance rear body, the appliance front body is of an integrated structure and contains occlusion of upper teeth and lower teeth, the appliance rear body is used for adjusting molar occlusion, and the appliance front body comprises a tooth guide groove, a breathing hole and a containing groove which act on the upper teeth and the lower teeth respectively; the front orthodontic appliance body comprises a front occlusal pad and a rear orthodontic appliance body, the front orthodontic appliance body is provided with a containing groove, the containing groove is an open groove located in the middle of the tail end of the front occlusal pad, the rear orthodontic appliance body comprises a rear occlusal pad, a cheek rear baffle, a lingual baffle and a connecting pad, the length and the thickness of the rear occlusal pad have various dimensions, and the front orthodontic appliance body and the rear orthodontic appliance body are detachably connected through the containing groove and the connecting pad which are matched with each other. The appliance front body or the appliance rear body can be selectively replaced according to the correction requirement, and the appliance has the advantages of being easy to operate, economical, practical and the like.

Description

technical field [0001] The present application relates to the technical field of orthodontics, in particular to a rear-end adjustable induction appliance, an orthodontic set and an orthodontic system. Background technique [0002] For early malocclusion appliances in the growth and development stage of children, there are two common types at present. One is the fixed appliance designed and made of traditional hard materials. Among them, the fixed appliance mostly uses wire brackets. Oral hygiene is difficult to maintain during the process, which is likely to cause adverse consequences, and the orthodontic force is relatively large, and the wearing comfort is poor, so children often refuse to wear it; Among them, the unbracket-free clear aligner is suitable for a limited number of people. Since the teeth in children's dentition period have not fully erupted, the compliance of the unbracket-free clear aligner is poor, while the silicone-based clear aligner It uses the mechani...

Problems solved by technology

[0002] For early malocclusion appliances in the growth and development stage of children, there are two common types at present. One is the fixed appliance designed and made of traditional hard materials. Among them, the fixed appliance mostly uses wire brackets. Oral hygiene is difficult to maintain during the process, which is likely to cause adverse consequences, and the orthodontic force is relatively large, and the wearing comfort is poor, so children often refuse to wear it; Among them, the unbracket-free clear aligner is suitable for a limited number of people. Since the teeth in children's dentition period have not fully erupted, the compliance of the unbracket-free clear aligner is poor, while the silicone-based clear aligner It uses the mechanism of biomechanics to slowly displace the teeth in the alveolar bone, so that the teeth that have erupted from the misplacement become neatly arranged, and the abnormal occlusal relationship is adjusted to normal. Soft, so it is the first choice for children's orthodontic appliances

[0003] However, since the silicone induction appliance is an orthodontic device imported from abroad, the silicone induction appliance is made according to the dental arch development data of foreign populations, and is not suitable for the dental arch shape of Chinese children, mainly manifested in the back end of the appliance It is not adjustable, especially the length of the back end of the appliance cannot be adjusted, and doctors often need to trim it and adjust it to a size suitable for children. The thickness of the splint at the back end of the appliance cannot be adjusted, so it is impossible to control the vertical development of the front and rear teeth. In modern society, the food is becoming more and more refined. If children's occlusal chewing function is not trained enough, it will easily lead to dysplasia of the jaw and alveolar bone
