Example one
The embodiment of the present application provides a method for constructing a crown-bridge model, and in a first embodiment of the method for constructing a crown-bridge model of the present application, with reference to fig. 1, the method is applied to a device for constructing a crown-bridge model, and the method includes:

and S50, generating a crown-bridge model at the missing tooth position based on the adjacent tooth model and the filling model so as to enable a user to carry out crown-bridge repair on the missing tooth patient based on the crown-bridge model.
In this embodiment, the application scenario is that, at present, when a doctor performs crown bridge repair treatment on a patient with a missing tooth, the doctor determines to obtain a treatment plan based on own treatment experience. Firstly, a doctor creates a corresponding solid oral cavity model according to the oral cavity condition of a patient, and can determine the missing teeth of the patient according to the solid oral cavity model. And then, determining an entity crown-bridge model at the missing tooth position according to the characteristics of the missing tooth and the characteristics of natural teeth around the missing tooth by a doctor, and finally, properly adjusting the entity crown-bridge model after communicating with a patient to obtain a final entity crown-bridge model. However, the solid crown-bridge model obtained by the subjective experience of the doctor has deviation from the actual requirements of the patient, so that the prior art has the problem of low treatment precision when performing crown-bridge repair on the patient with the missing tooth.
This embodiment is intended to improve the treatment accuracy in crown bridge repair of a patient with a missing tooth.
In this embodiment, the method for constructing a crown-bridge model is applied to a device for constructing a crown-bridge model.
The method comprises the following specific steps:
step S10, when a construction instruction is received, scanning the oral cavity of a user with missing teeth, and constructing a three-dimensional oral cavity model based on a scanning result;
in the present embodiment, the construction instruction is an instruction to construct a three-dimensional oral cavity model.
As an example, a user operates on a preset terminal interface, the terminal generates a building instruction according to the operation information of the user, and decides when to send the building instruction to the building device of the crown-bridge model based on the setting content of the user, the building instruction may be sent to the building device of the crown-bridge model at the current moment, and the building instruction may be sent to the building device of the crown-bridge model at the moment reserved by the user.
As an example, the construction apparatus of the crown bridge model, upon receiving the construction instructions, shows the physician that the parts are in place and can start the scan. After seeing the display information, the doctor guides the user of the missing tooth to open the mouth of the scanner for scanning by the scanner. The oral cavity of the user with the missing tooth is scanned through the scanner, a scanning result is obtained, and a three-dimensional oral cavity model is constructed based on the scanning result.
Step S10, when a construction instruction is received, scanning the oral cavity of a user with missing teeth, and constructing a three-dimensional oral cavity model based on the scanning result, wherein the step S11-step S12 comprises the following steps:
s11, when a construction instruction is received, scanning the oral cavity of a user with missing teeth to obtain the scanning data;
as an example, the construction device of the crown bridge model scans the oral cavity of the user with missing teeth when receiving the construction instruction, and obtains the scanned data. The scanning data may be image data or ultrasonic data, and is not limited to this.
As an example, if the scanner is an image-class scanner, the scanning result is obtained based on the image. If the scanner is an ultrasonic scanner, a scanning result is obtained based on the ultrasonic waves.
As an example, the step of obtaining the scan data by scanning the oral cavity of the user with missing teeth when receiving the construction instruction comprises:
and screening the image data to obtain image data meeting preset screening conditions, wherein the image data without natural teeth are removed.
As an example, after obtaining image data by an image scanner, the image data needs to be further screened because some images are blurred and cannot be directly used, or some images do not capture the teeth of a user with missing teeth. Therefore, the obtained image data is subjected to screening.
As an example, there are various indexes for measuring the image, including the fidelity of the image and the readability of the image. The fidelity of the image refers to the deviation degree of the evaluated image from the standard image. The smaller the deviation between the two, the higher the fidelity. The readability of an image refers to the ability of the image to provide information to a person or machine, which is not only related to the application requirements of the imaging system, but often also to the subjective perception of the human eye.
As an example, the quality indicators of the image include resolution and color depth.
As an example, the filtering condition may be that the resolution is higher than a preset resolution threshold, the filtering condition may also be that the color depth is higher than a preset color depth threshold, and the filtering condition may also be whether there is a natural tooth in the image.
As an example, the image data is filtered to remove image data without natural teeth, and image data with natural teeth is obtained.
And S12, inputting the scanning data into a preset neural network model, and processing the scanning data based on the neural network model to obtain the three-dimensional oral cavity model.
In this embodiment, the neural network model is a trained model, and is used for processing image data.
In this embodiment, the neural network model may be applied to a plurality of fields, including an automatic control field, a combinatorial optimization field, a pattern recognition field, a signal processing field, and the like.
As an example, the neural network model processes the filtered image data to obtain a three-dimensional oral cavity model.
As an example, before the step of inputting the scan data into the preset neural network model, the neural network model is obtained. The method comprises the steps of firstly obtaining oral cavity scanning image data of a plurality of missing tooth patients, using the data as sample data, screening the sample data to obtain a training data set and a test data set, building a model to obtain a model to be trained, training the model to be trained based on the training data set, and testing based on the test data set. When the test accuracy reaches a preset accuracy threshold, it is determined that the model training is finished, and the model obtained through training is used as the neural network model in the embodiment.
Step S20, dividing each natural tooth on the three-dimensional oral cavity model to obtain an independent natural tooth model;
in this embodiment, the user has a missing tooth in the oral cavity, and also has a natural tooth. The number of missing teeth may be 1 or more.
As an example, when the user has one missing tooth position, the natural teeth adjacent to the missing tooth are adjacent teeth, and the adjacent teeth may refer to one or two of the adjacent teeth.
As an example, the crown-bridge model construction device segments, i.e., divides, each natural tooth on the three-dimensional oral cavity model from the model. And (4) obtaining an independent natural tooth model after each natural tooth is separately divided.
Step S30, determining an adjacent tooth model corresponding to the missing tooth from the natural tooth model based on the distribution position of the missing tooth in the three-dimensional oral cavity model;
as an example, the distribution positions of the missing teeth are different for different patients, and the number of the missing teeth is different.
As an example, according to the distribution positions of different missing teeth, adjacent teeth of the missing teeth are determined, and the adjacent teeth are normal natural teeth. If there is only one missing tooth, the corresponding adjacent teeth are two adjacent teeth on the left side and the right side of the missing tooth, and if there are two missing teeth and the two missing teeth are adjacent, the adjacent teeth corresponding to the missing tooth are the adjacent teeth on the left side of the missing tooth on the left side and the adjacent teeth on the right side of the missing tooth on the right side.
After the adjacent teeth are determined, the corresponding model is the adjacent tooth model.
Step S30, determining an adjacent tooth model corresponding to the missing tooth from the natural tooth model based on the distribution position of the missing tooth in the three-dimensional oral cavity model, wherein the step S31-step S33:
step S31, determining the crown bridge model to be a single-side support or a double-side support based on the construction instruction;
as an example, when performing a crown bridge repair treatment for a patient with only one missing tooth, the selected crown bridge may be unilaterally supported or bilaterally supported.
As an example, the one-side supported crown bridge refers to a crown bridge in which a first dental prosthesis and a second dental prosthesis are fixed together, and two dental prostheses fixed together are called one-side supported crown bridge, in which a left adjacent natural tooth of a missing tooth is ground to be thin, and the first dental prosthesis and the second dental prosthesis are completely identical to the natural tooth before grinding. And (3) wearing the manufactured crown bridge model on the polished natural teeth by using the supporting force of the single-side natural teeth on the left side of the missing teeth as a bridge.
Similarly, as an example, the bilaterally supported crown bridge refers to a first dental prosthesis, a second dental prosthesis and a third dental prosthesis, which are manufactured by grinding and thinning two natural teeth on both sides of a missing tooth and are completely aligned with the natural teeth before grinding. Wherein the first, second and third dental prostheses are fixed together and the three dental prostheses fixed together are referred to as a bilaterally supported crown bridge.
Step S32, if the tooth model is determined to be supported on one side, determining an adjacent tooth model of the missing tooth in the direction of supporting one side from the natural tooth model based on the distribution position of the missing tooth;
as an example, if one-sided support is determined, which side a specific one-sided support is to be. This is because the missing tooth generally has two adjacent teeth on either side. Determining an adjacent tooth model of the missing tooth in a unilateral supporting direction from the natural tooth model based on the distribution position of the missing tooth.
And step S33, if the bilateral support is determined, determining a first adjacent tooth model and a second adjacent tooth model of the missing tooth in the bilateral support direction from the natural tooth model based on the distribution position of the missing tooth.
As an example, if it is determined as bilateral support, first and second adjacent tooth models of the missing tooth in the bilateral support direction are determined from the natural tooth model based on the distribution position of the missing tooth.
Step S40, generating a filling model at the missing tooth position based on the contour characteristics of the adjacent tooth model;
as an example, to make a dental prosthesis that is completely permanent with respect to the missing tooth, the specific shape of the missing tooth needs to be determined. Specifically, the shape of the missing tooth can be determined based on the adjacent teeth on both sides of the missing tooth. Therefore, a filling model at the missing tooth is generated based on the contour features of the neighboring tooth models, wherein the shape of the filling model is the shape of the replacement denture of the missing tooth.
And S50, generating a crown-bridge model at the missing tooth position based on the adjacent tooth model and the filling model so as to enable a user to carry out crown-bridge repair on the missing tooth patient based on the crown-bridge model.
As an example, image data of an adjacent tooth is obtained based on an adjacent tooth model, and image data of a replacement denture for a missing tooth is determined based on a filling model. And carrying out model training on the two parts of image data, and fusing again to obtain a crown bridge model at the missing tooth.
The user provides an overall treatment plan for the missing tooth patient based on the obtained crown bridge model.
Step S50, after the step of generating the crown bridge model at the missing tooth based on the adjacent tooth model and the filling model, the method comprises the steps S61-S63:
s61, acquiring a deflection material of a user, and selecting a blank of the deflection material;
as an example, a user may provide a crown bridge of multiple materials for a patient, the crown bridges of different materials have different service lives, the user provides multiple materials for the patient to select, and after selecting a biased material, the user selects a blank of the corresponding material.
Step S61, obtaining the deflection material of the user and selecting the blank of the deflection material, comprising the steps of A1-A2:
step A1, obtaining a deviation material of a user;
as an example, the construction device of the crown bridge model determines the biased material according to the input information of the user, and obtains the biased material of the user.
And A2, selecting the embryo with the color matched with the biased material from a preset embryo library based on the color of the natural tooth of the user.
As an example, the natural teeth of different users are different in color, and there are multiple colors of embryos in the embryo library.
And if the natural teeth of the user are dark in color and light in color, the embryo body which is matched in color and is biased to be made of material is released from the embryo body library according to the color of the natural teeth of the user.
Step S62, based on the crown and bridge model, cutting the blank through a preset first processing device to obtain a preliminary solid model;
as an example, after the model is determined, it is sent to the processing plant for processing. And based on the crown and bridge model, cutting the blank body through preset first machining equipment to obtain a preliminary solid model.
Step S62, based on the crown bridge model, before the step of cutting the blank body through a preset first processing device to obtain a preliminary solid model, the method comprises the steps B1-B2:
step B1, acquiring correction data of the crown bridge model;
as an example, after the model is determined, the model is sent to a processing plant for processing, and if the processing side determines that the sent model is not suitable for processing according to the processing environment and needs to correct the model, a correction suggestion is given, and specifically correction data is given. And the construction device of the crown bridge model acquires the correction data of the crown bridge model.
And B2, correcting the crown and bridge model based on the correction data.
As an example, the construction device of the crown and bridge model corrects the crown and bridge model based on the correction data.
And S63, based on the crown bridge model, polishing the preliminary solid model through preset second machining equipment to obtain a solid crown bridge.
As an example, after obtaining the corrected crown bridge model, the preliminary solid model is ground by a preset second machining device to obtain a solid crown bridge.
Compared with the prior art that the treatment precision is not high when the crown-bridge repair is carried out on a patient with missing teeth, the method, the device, the equipment and the storage medium for constructing the crown-bridge model have the advantages that when a construction instruction is received, the oral cavity of the user with the missing teeth is scanned, and the three-dimensional oral cavity model is constructed on the basis of the scanning result; dividing each natural tooth on the three-dimensional oral cavity model to obtain an independent natural tooth model; determining an adjacent tooth model corresponding to the missing tooth from the natural tooth model based on the distribution position of the missing tooth in the three-dimensional oral cavity model; generating a filling model at the missing tooth based on contour features of the adjacent tooth models; and generating a crown-bridge model at the missing tooth based on the adjacent tooth model and the filling model so as to enable a user to carry out crown-bridge repair on the missing tooth patient based on the crown-bridge model.
