In above-mentioned technical scheme, by loading and overlapping new tooth model and former tooth model, difference section is obtained, is led to
Cross calculating and obtain matrix information, difference section is calculated using tooth algorithm is arranged, invisible orthotic device is manufactured according to result, because
There are reference pair ratio and accurately calculating so that the accuracy of manufacture is higher, can greatly reduce manufacturing cost.
Correcting method is inserted in the midway for orthodontic of the two of the present invention, to be reached strong based on patient's preliminary scan
The former tooth model of effect is controlled, including：
Obtain the new tooth model that patient rescans；
By computer software programs load new tooth model and former tooth model and carry out it is overlapping, it is a set of it is impermeable substantially
Show, a set of translucent display, acquisition is used as difference section without overlapping part；
With regard to difference section, by calculating the matrix information for obtaining a new tooth model to former tooth model；
According to matrix information, difference section is calculated using tooth algorithm is arranged, invisalign is manufactured according to result of calculation
Device；
Making patient using invisible orthotic device, rescuing step reaches expected rectifying effect currently.
Further, the matrix information calculation procedure includes：
Every tooth in two set of model is calculated using existing dental features point in new tooth model and former tooth model
Coordinate system；
The origin of new tooth coordinate system is transformed into the origin position of former tooth coordinate system by translation and rotation；
Centered on origin, the X-axis of new tooth coordinate system is transformed into the X-axis position of former tooth coordinate system, new tooth
The Y-axis of coordinate system is transformed into the Y-axis position of former tooth coordinate system, obtains new tooth model to the matrix information of former tooth model.
In above-mentioned technical scheme, step is rescued by midway insertion, on the premise of former design is not changed in time
Adjustment, it is ensured that only after current rectifying effect has reached target, then rescuing for next step is carried out, rectified to follow-up
Control and lay a good foundation.
Brief description of the drawings
Fig. 1 is the flow chart of the manufacture method of the hidden tooth appliance of one of the present invention；
Fig. 2 is that the flow chart of correcting method is inserted in the midway for orthodontic of the two of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1, the manufacture method of the hidden tooth appliance of one of present invention, will be reached based on patient's preliminary scan
To the former tooth model of rectifying effect, comprise the following steps：
Step S11, obtains the new tooth model that patient rescans.
Step S12, loads new tooth model and former tooth model by computer software programs and carries out overlapping, acquisition does not have
There is overlapping part as difference section.
Step S13, with regard to difference section, by calculating the matrix information for obtaining a new tooth model to former tooth model.
Specifically, including：
Every tooth in two set of model is calculated using existing dental features point in new tooth model and former tooth model
Coordinate system；The origin of new tooth coordinate system is transformed into the origin position of former tooth coordinate system by translation and rotation；With original
Centered on point, the X-axis of new tooth coordinate system is transformed into the X-axis position of former tooth coordinate system, the Y-axis of new tooth coordinate system is turned
The Y-axis position of former tooth coordinate system is changed to, center is identical, and X-axis is identical, and Y-axis is identical, Z axis is also just identical, so as to obtain new tooth
Matrix information of the tooth model to former tooth model.
Step S14, according to matrix information, is calculated difference section using tooth algorithm is arranged, is manufactured according to result of calculation
