Abstract
The invention discloses a kind of manufacturing methods of hidden tooth appliance, and the former tooth model of rectifying effect is reached based on patient's preliminary scan, comprising: obtain the new tooth model that patient rescans；New tooth model and former tooth model are loaded by computer software programs and is overlapped, and obtain unfolded part as difference section；With regard to difference section, be obtained by calculation a new tooth model to former tooth model matrix information；According to matrix information, difference section is calculated using row's tooth algorithm, invisible orthotic device is manufactured according to calculated result.The accuracy of manufacture is high, and manufacturing cost can be effectively reduced.
Description
Technical field
The present invention relates to dental appliances.
Background technique
It may cause the effect of orthodontic that expection is not achieved because of some uncertain factors during orthodontic,
The appliance manufactured is not available, so that subsequent rescue can not carry out, entire scheme can only be redesigned, to increase
Addition sheet.Moreover, the invisible orthotic device of manufacture, often because error makes the accuracy of manufacture very low, needs more because uncertain
Secondary adjustment substantially increases manufacturing cost to manufacture multiple appliances.
Summary of the invention
The purpose of the present invention is to provide a kind of manufacturing methods of hidden tooth appliance, and the accuracy of manufacture is high, can effectively drop
Low manufacturing cost.
Realizing the technical solution of above-mentioned purpose is:
The manufacturing method of hidden tooth appliance of the invention, the original of rectifying effect will be reached based on patient's preliminary scan
Tooth model, comprising:
Obtain the new tooth model that patient rescans；
New tooth model and former tooth model are loaded by computer software programs and is overlapped, and are obtained unfolded
Part is used as difference section；
With regard to difference section, be obtained by calculation a new tooth model to former tooth model matrix information；
According to matrix information, difference section is calculated using row's tooth algorithm, invisalign is manufactured according to calculated result
Device.
Further, the matrix information calculating step 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 translating and rotating；
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, obtain new tooth model to former tooth model matrix information.
In the above technical solution, by loading and being overlapped new tooth model and former tooth model, difference section is obtained, is led to
It crosses calculating and obtains matrix information, difference section is calculated using row's tooth algorithm, invisible orthotic device is manufactured according to result, because
There is reference pair ratio and accurately calculate, so that the accuracy of manufacture is higher, manufacturing cost can be greatly reduced.
Detailed description of the invention
Fig. 1 is the flow chart of the manufacturing method of hidden tooth appliance of the invention；
Fig. 2 is the flow chart of the midway insertion correcting method for orthodontic of the invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
Referring to Fig. 1, the manufacturing method of hidden tooth appliance of the invention, will be reached strong based on patient's preliminary scan
Control the former tooth model of effect, including 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 is overlapped, and acquisition does not have
There is the part of overlapping as difference section.
Step S13, with regard to difference section, be obtained by calculation a new tooth model to former tooth model matrix information.
Specifically, comprising:
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 translating and rotating；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, and Z axis is also just identical, to obtain new tooth
Matrix information of the tooth model to former tooth model.
Step S14 calculates difference section using row's tooth algorithm, is manufactured according to calculated result according to matrix information
Invisible orthotic device.
Referring to Fig. 2, correcting method is inserted into the midway for orthodontic, to reach and rescue based on patient's preliminary scan
The former tooth model of effect, including the following steps:
Step 21, the new tooth model that patient rescans, and head photo, oral cavity photo and the X-ray of shooting are obtained
Photo.
Step S22 loads new tooth model and former tooth model by computer software programs and is overlapped, using not
Same color, a set of opaque display, a set of translucent display obtain unfolded part as difference section.
Step S23, with regard to difference section, be obtained by calculation a new tooth model to former tooth model matrix information,
It specifically 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 translating and rotating；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, and Z axis is also just identical, obtains new tooth mould
Matrix information of the type to former tooth model.
Step S24 calculates difference section using row's tooth algorithm, is manufactured according to calculated result according to matrix information
Invisible orthotic device cooperates the head photo, oral cavity photo and X-ray photograph of shooting, rectifys patient currently using invisible orthotic device
It controls step and reaches expected rectifying effect, facilitate subsequent rescue.
Above embodiments are used for illustrative purposes only, rather than limitation of the present invention, the technology people in relation to technical field
Member, without departing from the spirit and scope of the present invention, can also make various transformation or modification, therefore all equivalent
Technical solution also should belong to scope of the invention, should be limited by each claim.
