Specific embodiment
Below by drawings and Examples, technical scheme is described in further detail.
The flow chart of one embodiment of denture processing method of the invention is as shown in Figure 1.
In a step 101, the alveolar ridge data of patient are obtained.In one embodiment, can be by scanning the tooth of patient
Groove ridge die or alveolar ridge model obtain alveolar ridge data.
In a step 102, according to alveolar ridge data in complete denture template database selection target artificial tooth template.Full mouth
Artificial tooth template database includes multiple standard artificial tooth templates, and standard artificial tooth template can be complete denture scan data, or entirely
Mouth denture designing data.In one embodiment, alveolar ridge data can be entered with the data in complete denture template database
Row fuzzy matching, obtains the standard artificial tooth template matched the most with the alveolar ridge data of patient as target artificial tooth template.
In step 103, according to target artificial tooth template and alveolar ridge data acquisition complete denture design data.In a reality
Apply in example, row's tooth, adjustment and the operation merged with the alveolar ridge surface data of patient can be carried out on the basis of template, with
Obtain complete denture design data.In one embodiment, due to target artificial tooth template and patient alveolar ridge data not necessarily
Can completely match, therefore can be finely adjusted to improve the standard of complete denture design data on the basis of target artificial tooth template
Exactness.
In the operation of artificial tooth jewelry making practice, the inventors discovered that can be according to the personal considerations of patient for different patients design
The form of the complete denture of making is roughly divided into several types, and the difference of the complete denture of same type is smaller.By so
Method, the alveolar ridge data of patient can be matched with the standard artificial tooth template data in ATL, so as to be fitted
Together in the standard artificial tooth template of patient, further complete denture design is carried out based on the template, so as to instead of traditional-handwork
Cumbersome, the complicated manual steps of complete denture are made, the automaticity and denture processing of complete denture design is improve
Efficiency.
In one embodiment, jaw bow curve data, base edge can be included in the alveolar ridge data of the patient of acquisition
Line number is according to one or more in, alveolar ridge data.In one embodiment, can be to the alveolar ridge die or alveolar ridge of patient
Model scanning data carry out feature extraction, obtain jaw bow curve data, base edge line data, alveolar ridge data, it is also possible to logical
The mode for crossing intraoral 3-D scanning obtains alveolar ridge data.During jaw bent into curve data, base edge line data, alveolar ridge data
One or more matched with standard artificial tooth template, obtain target artificial tooth template.
By such method, can be matched to obtain target artificial tooth template using clear and definite characteristic, so that
Operand is reduced, the performance requirement to realizing equipment is reduced, efficiency is also further increased, is easy to expanded application.

Groove ridge die or alveolar ridge model obtain alveolar ridge data.In one embodiment, can be using Germany Smart Optics
The scanner of 880Dental Scanner companies model Smart Optics is scanned operation.
In step 202., the combination of the artificial front and rear tooth form number of patient is determined.The determination of tooth model can include
Selection Upper Anterior Teeth, lower labial teeth, the several parts of backteeth.
In the choice during anterior teeth model, if clinical providing carries tooth jaw plane and richness, center line and mouth
The standard wax dike of linea angulata, then can determine Upper Anterior Teeth tooth form number based on the standard wax dike, can specifically include：
(1) face contour according to patient selects the type of artificial tooth, and the type of artificial tooth can be including S (Square, side
It is circular), T (Tapering, point is circular), three kinds of O (Ovoid, oval).
(2) on measurement patient's bite block between bilateral line of angulus oris incisxal edge line curve distance, subtract after 4-5mm with various width
Same tooth form artificial tooth compare selection Upper Anterior Teeth convenient width, selection with the immediate model of normal width.
In the case where clinic is without standard wax dike is provided, bilateral alveolar ridge top line should be drawn first and is prolonged forwards, backwards
It is long, then draw the bisector (lip jaw side is divided equally) of incisive papilla and extension to the left and right intersects with alveolus crestal culmination extended line.Take two
The distance between crosspoint determines labial teeth width (two crosspoints are the axial points of bilateral canine tooth).
According to the model of selected Upper Anterior Teeth, can correspond, it is determined that the model of lower labial teeth.
After selection during tooth, selection according to eye tooth it is remote in (line of angulus oris and incisxal edge line intersection point are on alveolar ridge of mandible
Subpoint, to mobile 1.5mm in remote or so) with lower molar after before pad 2-5 millimeters of distance confirm the length of backteeth 4-7,
4 or 7 teeth can less be arranged according to the absorbing state of alveolar ridge and precipitous situation selectivity, and then obtain the artificial of Edentulous Cases
Backteeth model.
In one embodiment, after the combination of artificial front and rear tooth form number is completed, can be by data inputting to hold
The ensuing screening operation of row.
In step 203, according to obtain it is artificial before and after tooth form number combination screening complete denture template database
In standard artificial tooth template, obtain initial screening artificial tooth template；Alveolar ridge data are matched in initial screening artificial tooth template, target is obtained
Artificial tooth template.In one embodiment, complete denture template database includes the artificial front and rear tooth of each standard artificial tooth template
Type information, can store standard artificial tooth template classification according to the combination of tooth form number before and after artificial is different, so as to
The standard artificial tooth template of correspondence classification is selected during matching somebody with somebody carries out further screening matching.
In step 204, according to target artificial tooth template and alveolar ridge data acquisition complete denture design data.
By such method, the artificial front and rear tooth form number of patient can be first obtained, and tentatively be sieved on this basis
Choosing, so as to greatly reduce matched data amount, further increases the efficiency of denture processing, and reduces to equipment fortune
The requirement of calculation level.
Flow chart such as Fig. 3 institutes of one embodiment of alveolar ridge Data Matching in denture processing method of the invention
Show.
In step 301, according to obtain it is artificial before and after tooth form number combination screening complete denture template database
In standard artificial tooth template, obtain initial screening artificial tooth template.In one embodiment, complete denture template database includes respectively
The artificial front and rear tooth type information of individual standard artificial tooth template, can be different by standard according to the combination of artificial front and rear tooth form number
Artificial tooth template classification is stored.
In step 302, curve data screening initial screening artificial tooth template is bent according to jaw, obtains postsearch screening artificial tooth template.
