The invisible appliance comprises a tooth discharging groove, a base, a lip side surface and a tongue side surface. The invisible appliance has the beneficial effects that the lip side surface and the tongue side surface have certain difference from a staggered tooth jaw, and the appliance can generate force for enabling teeth to move towards the direction of a displacement load applied by the teeth after deformation, so that the teeth generate a certain amount of movement, and finally the staggered teeth are corrected; the thickness of the tongue side surface is larger than that of the lip side surface, and the thickness of the invisible appliance is controllable, so that the deformation force application of the appliance is larger, the force of the external expansion dental arch is larger than the counter-acting force, and the external expansion movement of the teeth is achieved; in the step A, the intraoral tooth jaw is scanned by using three-dimensional scanning to establish a three-dimensional digital model, so that a comprehensive three-dimensional tooth jaw shape can be obtained, and a gypsum tooth model can be converted into an operable digital model; and in the step C, a resin tooth model is manufactured by using a 3D printing technology, so that rapid, accurate and convenient conversion is realized, and popularization and use are facilitated.
Description
Technical field
The present invention relates to a kind of appliance, specially a kind of labial teeth area extends out invisible orthotic device and its manufacturer of dental arch
Method belongs to medical oral gear division orthodontic technology field.
Background technology
The movement of incisor lip side is suitable for the crowded dentition that incisor is more upright or tongue inclines, and traditional teeth rescues the realization of technology
Method is to reinforce unit lip on fixed appliance with vertical loop to bend Omega to development labial teeth, or in the cheek Guan Jinzhong that grinds one's teeth in sleep
Bent arch wire imposes incisor lip to inclined power to incisor.
And the production process of stealthy dental appliance is：First, the fast development of three-dimensional laser scanning technique makes gypsum tooth
Mould is converted into operable mathematical model, and no subsequent work of mathematical model is not all known where to begin；Secondly, CAD
Fast development with graphics allows developer to realize the 3D softwares of various functions using its various algorithm development, this is soft
Part system needs to complete to edit the processing of digital tooth mould, is formed and final rescues scheme etc., finally, rapid laser-shaping technique
That is the fast development of 3D printing technique have been realized in by digital model quickly, be accurately, easily converted to resin tooth mould
The process of type turns in resin tooth model by figure again by hot pressing plastics sucking moulding technology and makes transparent dental appliance, and
This elasticity, transparent appliance are exactly stealthy dental appliance, are commonly called as " stealthy facing ", the work of stealthy dental appliance
Principle is exactly by after the mobile malposed tooth jaw mathematical model to ideal position in rescuing system software, being with ideal dentognathic model
Formpiston makes invisible orthotic device, and patient-worn has the invisible orthotic device of certain difference with malposed tooth jaw, can be produced after appliance deformation
The strength of the raw displacement loading direction movement for making tooth be applied to it, finally makes malposed tooth be corrected, that is to say, that stealthy
The generation of the power of appliance is caused by displacement effect, and the metamorphosis after wearing is in corona, to make tooth generate one
Quantitative movement finally makes tooth become neat and completes correction process, however, due to entirely rescuing in scheme caused by each step
The synergistic effect of deviation causes final rectifying effect to deviate the design effect before rescuing, in order to eliminate above-mentioned rectifying effect and set
The deviation between effect is counted, needs constantly to redesign scheme, make light-cured resin prototype and compacting invisible orthotic device, this
Sample not only increases human cost and the cost of raw material, but also extends and rescue the period, also reduces doctor and patient to invisalign
The satisfaction of technology is unfavorable for the popularization of invisible orthotic device.

It states at the gap that pedestal is arranged between lip side and tongue side face and labial teeth area, the lip side, the lip side and tongue side face
In arc-shaped is distorted, the lip side is located at the outside in labial teeth area, and the tongue side face is located at the inside in labial teeth area.
A kind of labial teeth area extends out the invisible orthotic device of dental arch, and manufacturing method includes the following steps：
Step A, dentognathic model in scanning mouth, establishes tooth jaw mathematical model.
Step B designs pedestal, and the processing completed to digital tooth mould is edited, and tongue side face base is carried out in software Geomagic
Seat is horizontal to be thickeied, and lip side base level thickeies.
Step C carries out virtual row's tooth, in order to which digital model is converted to resin tooth model.
Step D is turned in resin tooth model by hot pressing plastics sucking moulding technology and is made transparent dental appliance.
Preferably, in order to generate the power of the displacement loading direction for making tooth be applied to it movement, the lip side and tongue
There is certain difference in side with malposed tooth jaw.
Preferably, in order to enable the power for extending out dental arch is more than reaction force, reach tooth and extend out movement, the tongue side face is thick
Degree is compared with lip side thickness.
Preferably, in order to obtain the tooth jaw shape of comprehensive solid, in the step A, by using 3-D scanning pair
Mouth interior tooth jaw is scanned to establish three-dimensional digital model.
Preferably, it quickly, is accurately, easily converted to realize, in the step C, is made and set using 3D printing technique
Fat tooth model.
The beneficial effects of the invention are as follows：The labial teeth area extends out the invisible orthotic device and its manufacturing method reasonable design of dental arch,
There is certain difference in lip side and tongue side face with malposed tooth jaw, will produce the displacement for making tooth be applied to it after appliance deformation
The strength of loading direction movement finally makes malposed tooth be corrected, tongue side face thickness to make tooth generate a certain amount of movement
Compared with lip side thickness, invisible orthotic device thickness is controllable, and to which appliance deformation force is bigger, biasing effect is controllable so that extends out tooth
The power of bow is more than reaction force, reaches tooth and extends out movement, in step A, is swept by using 3-D scanning counterpart interior tooth jaw
It retouches to establish three-dimensional digital model, the tooth jaw shape of comprehensive solid can be obtained, it is operable in order to which gypsum tooth mould to be converted into
Mathematical model, in step C, resin tooth model is made using 3D printing technique, is realized quickly, accurately, easily convert, just
In popularization and use.
