Fig. 2 be corona veneer of the present invention digitalized design method in patient's smile curve graph.
Specific embodiment
The present invention provides a kind of digitalized design method of corona veneer, to make the purpose of the present invention, technical solution and effect
Fruit is clearer, clear and definite, referring to the drawings and gives an actual example that the present invention is described in more detail.It should be appreciated that this place is retouched
The specific embodiment stated is only used to explain the present invention, is not intended to limit the present invention.
Fig. 1 is referred to, Fig. 1 is the step flow chart of the digitalized design method of corona veneer of the present invention, the corona patch
The digitalized design method in face, includes the following steps：
Step S10, the three-dimensional modeling data of corona in patient mouthful is obtained by scanner in mouth.Scanner will in the mouth
Three-dimensional modeling data is uploaded to host.In order to skilled worker designer corona veneer is designed on host.Preferably, it is described
Scanner digitizes scanner in mouth for the TRIOS of 3SHAPE companies in mouthful.
Step S20, the smiley image and the corona image of open that acquisition patient dehisces；Wherein, smiley image is to be used for
Design smile curve and for examining corona veneer design effect, corona image are for understanding the whole of corona in patient mouthful
Body situation and for corona colorimetric.Specifically, the step S20 is specifically included：
Step S210, when patient dehisces to smile, the smiley image of corona is exposed at front shooting patient facial region's mouth；When
It can also be so to be filmed the entire face of patient, and the image at mouth is intercepted in entire picture.
Step S220, when patient's open, the corona image out of all angles shooting patient mouthful passes through the corona figure
Concrete condition as that can understand corona in patient mouthful on the whole provides basic information for the design of corona veneer, specifically, institute
Step S220 is stated to specifically include：
Step S221, the first corona image during lower jaw occlusion upper from front shooting patient；
Step S222, the second corona image during lower jaw separation upper from front shooting patient；
Step S223, third corona image during lower jaw occlusion upper from left side shooting patient；
Step S224, the 4th corona image during lower jaw occlusion upper from right side shooting patient；
Step S225, the 5th corona image for clapping patient's facies maxillaris is faced upward from front；
Step S226, it takes a crane shot the mandibulofacial 6th corona image of patient from front.
The step S20 is further included：Step S200, the CBCT or X-ray in patient mouthful are obtained, then obtains the smile of patient
Image and corona image, it is preferred that the CBCT or X-ray in patient mouthful are provided, for understanding the health of each tooth of patient
Situation.
Step S30, the smiley image of two dimension is converted by 3-D view by D reconstruction design software.That is, doctor
By the smiley image of shooting be passed to skilled worker host in, by D reconstruction design software by two dimension smiley image convert
Into 3-D view.The D reconstruction design software is preferably the software using 3-Sweep technologies（That is 3-Sweep softwares）.
It is of course also possible to be Photofly softwares, the present invention is not construed as limiting.
Step S40, the three-dimensional modeling data and 3-D view are combined to the 3D models formed when patient smiles.By institute
It states three-dimensional modeling data and includes the data such as position, size, shape of each tooth in oral cavity.And the 3-D view reflection is
Position relationship of lip and tooth etc. outside oral cavity, therefore, the 3D models include the 3D data in patient mouthful and outside mouth.The step
Rapid S40 is specifically included, and in the Three-dimensional Design Software of the host, the three-dimensional modeling data and 3-D view are incorporated in one
It rises, and the 3-D view is corrected according to the three-dimensional modeling data, the two is fused to 3D moulds when patient smiles
Type.The step S40 is further included：The 3D models are printed by 3D printer, in this way, it is possible to provide patient is intraoral
The truth of each tooth designs the corona of bad tooth and corona veneer convenient for doctor.
Step S50, patient's smile curve, that is, curve of smiling are designed on corona image.
As shown in Fig. 2, Fig. 2 be corona veneer of the present invention digitalized design method in patient's smile curve graph, specifically,
The step S50 is specifically included：
Step S510, corona image is put into using digital facebow as X-axis, using center line as in the coordinate system of Y-axis；
Step S520, it is divided into two using center line as symmetry axis from corona image middle part；
Step S530, patient's smile curve is designed on corona image by the coordinate system.
Step S60, according to patient's smile curve and 3D models, virtual corona veneer is designed, and by the virtual tooth
Hat veneer is superimposed upon on the corresponding position of smiley image.The step for, it is realized in dormitory Three-dimensional Design Software.
Specifically, the step S60 is specifically included：
S610, by the Three-dimensional Design Software, the original size ratio of each corona of patient is measured on corona image,
Such as the lateral dimension ratio of corona and vertical dimension ratio.
S620, based on patient's smile curve, the original size ratio of each corona in 3D models is adjusted, and hook
The corona form after adjustment is strangled out, which need to meet the aesthetic requirement of current patents；
The dimension scale of each corona of 3D models after S630, reference adjustment, designs virtual corona on corona
Veneer, and the virtual corona veneer is superimposed upon on the corresponding position of corona image, certainly, also by the virtual corona veneer
On the 3D models of superposition after the adjustment, make the 3D models that can really simulate patient and use the effect after corona veneer.Upper
Under the frame for stating corona form, by corona veneer, to patient, original corona compensates, it is made finally to meet the tooth after adjustment
Crown state.
S640, the virtual corona veneer is superimposed upon on the corresponding position of smiley image, with test design effect.
After patient is satisfied with this corona recovery scenario, corona veneer three-dimensional data is imported into lathe, and pass through machine
Bed processes corona veneer, then full porcelain tooth is made out by traditional fabrication artificial tooth technique and is preced with veneer, and be bonded on patient's corona
Corresponding position compensate, be finally completed corona reparation.
In conclusion a kind of digitalized design method of corona veneer provided by the present invention, in this way, can be right
The progress of corona veneer is pre-designed, and can carry out simulation and try on, and patient can watch desired effect, and root before corona reparation
Corona recovery scenario is adjusted according to the hobby of patient, after patient confirm after, then according to confirm after corona recovery scenario into
Row corona veneer makes, and the corona veneer to complete is bonded in the corresponding position on patient's corona.
It should be understood that the application of the present invention is not limited to the above, it for those of ordinary skills, can
To be improved or converted according to the above description, all these modifications and variations should all belong to the guarantor of appended claims of the present invention
Protect range.
