Background
The materials of the false teeth which are widely used clinically at present are zirconia and glass ceramics, and the zirconia occupies most of the false teeth due to the advantages of high hardness, difficult deformation and the like. Wherein, after the zirconia false tooth is cut, the quality of the finished product tooth can be achieved only by sintering, and the zirconia sintering generally needs 8-10 hours. Because of the demands of denture manufacturing quantity, existing denture manufacturers generally put a plurality of dentures into the same sintering furnace for simultaneous sintering, and then sort the dentures after sintering. Except for a certain degree of identification of a dental bridge (a plurality of connected teeth), the shapes of other teeth are not very different, so that the sintered denture and a dental model of a patient can only be tried on one by one to find an order (or a dental box) where the teeth are located. However, the above method of trying to sort each denture one by one has the following drawbacks: and (1) the sorting takes long time and the sorting efficiency is low. Taking the example of sintering 30 dentures at one time, the first denture needs to be worn at most 30 times, the second denture needs to be worn at most 29 times, and so on, the 30 dentures need to be worn at most 30+29+28+27+. + -. 1=465 times, and the sorting efficiency is low; (2) Because the form difference of some false teeth is very small, the condition that a plurality of false teeth can correctly wear the dental cast often appears, so that the judgment needs to be carried out by depending on the professional of an operator, the error probability is higher, the accuracy is poor, and the professional requirement on the operator is high.

The denture parameter data includes, but is not limited to, the number of each denture included, the weight before sintering, the steps from the completion of cutting to the denture before sintering, and denture selected material data, wherein the denture selected material data is a denture finished material, and the exact density corresponding to the denture selected material data selected or inputted by the user can be searched in a preset database. Specifically, the density data corresponding to the finished denture processing material of each manufacturer are public data, are collected and verified in advance, and are stored in a preset database in an associated manner.
And S102, calculating to obtain the volume data of the denture model corresponding to each denture through the rear end according to the denture model data of each denture.
Firstly, the design model of each denture is a closed body, and the back end can calculate accurate denture model volume data corresponding to each denture through an algorithm built in denture sorting auxiliary software.

And the back end divides each denture according to the denture model data and the model vertex data of each denture to obtain a plurality of triangular patch data corresponding to each denture, and calculates to obtain the denture model volume data corresponding to each denture according to the triangular patch data obtained by division.
Referring to fig. 3, the step S204 of obtaining the data of the dental prosthesis volume corresponding to each dental prosthesis by calculating according to the data of the plurality of model patches corresponding to each dental prosthesis by the back end may further be obtained by: step S300, calculating to obtain patch volume data corresponding to each model patch data according to a plurality of model patch data corresponding to each denture through the rear end; and step S302, respectively combining the surface patch volume data corresponding to each model surface patch data corresponding to each false tooth through the rear end to obtain the artificial tooth model volume data corresponding to each false tooth. In the previous example, the denture sorting auxiliary software at the rear end obtains a first triangular patch by calling a function method of a math library in a Python standard library, and obtains three vertexes of the first triangular patch, wherein three vertexes correspond to three-dimensional coordinates according to a counterclockwise sequence, and the three coordinates are (x) respectively 11 ，y 11 ，z 11 ）、（x 12 ，y 12 ，z 12 ）、（x 13 ，y 13 ，z 13 ) Based on the three vertex coordinates of the first triangle patch and equation 1:
V i = |(−x i3 y i2 z i1 +x i2 y i3 z i1 +x i3 y i1 z i2 −x i1 y i3 z i2 −x i2 y i1 z i3 +x i1 y i2 z i3 ) (1/6) |, calculating to obtain patch volume data V1 of the first triangular patch, wherein V i Representing the patch volume data corresponding to the ith model patch data, wherein x, y and z respectively represent the coordinate values of three vertexes in the model patch data in a three-dimensional space coordinate system, and by analogy, calculating to obtain patch volume data corresponding to each triangular patch, and substituting the patch volume data of all triangular patches corresponding to each denture into a formula 2: v total =∑ i V i Summing the patch volume data of all triangular patches corresponding to a denture to obtain denture model volume data V corresponding to the denture total 。
For example, taking a certain denture model data as an example, 27557 model vertexes are obtained, 55110 model patches are obtained by segmenting the denture, and x is the coordinate value of three vertexes of a first triangle patch 11 = -1.680549，y 11 = -49.935905，z 11 = -2.455484，x 12 = -1.729336，y 12 = -50.001141，z 12 = -2.456306，x 13 = -1.731409，y 13 = -49.971203，z 13 = 2.481415; substituting the formula 1 to calculate the patch volume data of the first triangular patch, repeating the above steps, substituting all triangular patch data into the formula 1 to calculate the patch volume data corresponding to each triangular patch, and summing the patch volume data of all triangular patches to obtain the corresponding denture model volume data, such as 413.79 cubic millimeters.
And step S104, calculating to obtain the predicted sintered weight of each denture through the back end according to the denture model volume data of each denture and the corresponding denture parameter data, and sending the predicted sintered weight of each denture to the server.
In this embodiment, the denture model volume data and the corresponding denture parameter data for each denture are input into a preset denture weight prediction model, and the predicted post-sintering weight of each denture is calculated. In an exemplary embodiment, the denture parameter data includes the number of teeth each denture contains, the pre-sintered weight, the steps the denture undergoes from the completion of the cutting to the pre-sintering, and denture selected material data. Inputting the denture model volume data and the corresponding denture parameter data of each denture into a preset denture weight prediction model can be understood as inputting the number of each denture, the weight before sintering, the steps from cutting completion to denture experience before sintering, denture selected material data (material brand) and the denture model volume data into the preset denture weight prediction model, and calculating the predicted sintered weight of each denture. Further, the predicted sintered weight of each denture is sent to the server, so that the server can store the predicted sintered weight in a preset database.
For example, referring to fig. 4, the step S104 of calculating the predicted sintered weight of each denture by the back end according to the dental model volume data and the corresponding denture parameter data of each denture may further include steps S400 to S404, where: step S400, acquiring the volume contraction ratio corresponding to each denture through the data of the denture model volume of the rear end based on each denture; step S402, obtaining an average weight change ratio corresponding to each denture through the back end according to the number of each denture, the weight before sintering, the steps from the cutting to the denture before sintering and the data of the materials selected by the denture; and step S404, calculating the predicted sintered weight corresponding to each denture through the back end according to the denture model volume data, the volume shrinkage ratio and the average weight change ratio of each denture. In this embodiment, the predicted sintered weight corresponding to each denture is calculated by combining the volume shrinkage ratio, the average weight change ratio, the industrial experience value, and the denture model volume data of each denture.
In an exemplary embodiment, the method further includes constructing a model to be trained, and training based on the model to be trained to obtain the preset denture weight prediction model; as shown in fig. 6, the details are as follows: step S600, obtaining a plurality of sample data of a plurality of sample dentures which are sintered by a plurality of sintering furnaces, wherein the plurality of sample data comprise the number of dentures, the weight before actual sintering, the steps from cutting completion to denture before sintering, the data of materials selected by the dentures and the weight after actual sintering; step S602, classifying a plurality of sample data of the plurality of sample dentures based on the sintering time of the completed sintering and the sintering furnace in which the sample dentures are located, to obtain sample data of a plurality of groups of sample dentures, wherein the sample dentures of the same group are all sintered in the same sintering furnace at the same sintering time; step S604, respectively inputting the sample data of the sample dentures of each group into a model to be trained, and outputting the predicted sintered weight of the sample corresponding to each denture in each group; step S606, comparing the predicted sintered weight of the sample corresponding to each denture in each group of samples with the corresponding actual sintered weight to obtain a corresponding loss value; step S608, based on the corresponding loss value, adjusting the model parameters in the model to be trained to obtain trained model parameters; step S610, obtaining the preset denture weight prediction model based on the trained model parameters. In this embodiment, the denture weight prediction model can be understood as a weight change rule before and after denture sintering under different scenes, and needs to be calculated through a large amount of test data, so that a large amount of sample data of actually delivered dentures needs to be collected for repeated verification and adjustment.
And S106, after each denture is placed into the same sintering furnace for sintering, acquiring the actually sintered weight of each denture through the rear end, and sending the actually sintered weight of each denture to the server.
