Abstract
The invention relates to a device for inducing reasonable arrangement of teeth of children and a manufacturing method of the device. Based on a three-dimensional model of a standard upper jaw and a standard lower jaw in a standard occlusal relation and a tooth socket in a dental arch track and form design, the device comprises upper and lower notches, side wall flanges at lip sides and tongue sides and breathing holes, wherein the shapes, the sizes and the spatial arrangement position of the upper and lower notches are designed according to standard tooth jaws; the upper and lower notches are different from teeth to be induced so that the notches generate a certain induction force for the teeth to be induced to induce the teeth to be reasonably arranged in the target direction; and the side wall flanges at the lip sides and the tongue sides are designed according to gums and mucosae of the standard upper jaw and the standard lower jaw in the standard occlusal relation, the oral and perioral soft tissue forms are adjusted so as to achieve the final effect of teeth induction. According to the dental arch line track of a patient, an appropriate tooth socket is selected, the manufacturing cost is reduced, the efficiency is improved, the financial burden is reduced for the patient and meanwhile the purpose of inducing reasonable arrangement of the teeth of the children is achieved.
Description
Technical field
The present invention relates to a kind of induction raisonne device of teenager teeth and manufacture method thereof, be applied to orthodontics.
Background technology
Medically by sticking up before people's chin, retrude or anisodont phenomenon be called malocclusion.The generation of the oral diseases such as malocclusion usually can cause various focusing depths represented, atrophy, bleeds, odontoseisis, early mistakes, affect oral health and also can cause facial deformity, affects beauty.Meanwhile, malocclusion also has a strong impact on social activity and work, and especially teenager and child usually becomes and feel oneself inferior owing to being subject to classmate or junior partner's ridicule, affects child's mental health.The investigation demonstration of China's stomatology meeting, Chinese children is 51.84% in the malocclusion prevalence of milk teeth period, and replacing the tooth phase is 71.21%, and the permanent teeth initial stage is 72.92%.
For the treatment of malocclusion, medically often take the method for orthodontics to carry out.Orthodontics is by the method such as correction or surgical operation treatment malocclusion.Common antidote mainly contains removable appliance, fixed appliance, function corrector and orthognathic surgery clinically.Wherein the fixed appliance taking metal bracket as representative and invisible orthotic device are the most frequently used.
There are the following problems for existing appliance:
1,, when metal bracket appliance elastic metallic arch wire is induced, metal arch wire is to be delivered on tooth and tooth sentence by a little metal bracket to the effect of tooth and tooth jaw.Tinsel is that point contacts or line contact with the way of contact of bracket.Fixing teeth appliance, because needs are fixed on facing, is worn for a long time and can be caused damage to tooth body and periodontal tissue.And the image of usually giving people's " iron teeth copper tooth ", affect attractive in appearance and social.
The advantages such as 2, stealthy appliance has personalization as existing novel fixed appliance, attractive in appearance, but stealthy appliance is to make based on the vacuum forming technology of thermoplastic, material hardness is large, wears difficulty, uncomfortable, and this personalized complex manufacturing process, the cycle is long, and cost is high.
Teenager teeth exists the significantly different tooth jaws that are to be grown up to shape from adult tooth, under naturalness, can not change, and child's tooth jaw still changes the phase in Rational Arrangement, even in the permanent teeth phase, tooth is still unstable, therefore, should be to induce its Rational Arrangement as main for teenager teeth, instead of correct.Existing appliance has laid stress on tooth, skeleton, and has ignored in oral cavity and the effect of mouthful all soft tissues, and mouthful phychology and a function interior and mouthful all soft tissues have a great impact the normal position that maintains denture in fact.
Summary of the invention
The object of the present invention is to provide a kind of induction raisonne device of teenager teeth and manufacture method thereof, be intended to overcome weak point above-mentioned existing dental jaw deformity corrector, braces and associated teeth abductive approach, and according to the residing special circumstances of teenager teeth, realization reaches the raisonne target of teenager teeth simply, conveniently, cheaply.The present invention is based on the standard upper jaw under standard occluding relation and threedimensional model and the dental arch track form of standard lower jaw, utilize forward software design to go out the threedimensional model of soft magnetism power facing, and utilize CAE, CAM technology, under the control of computer, according to this threedimensional model, adopt injection molding technology to produce the raisonne device of induction teenager teeth.
