[0065] The function implemented by the method for determining layout information of a scanning rod provided by the embodiments of the present application can be realized by calling program code by the processor of the electronic device, and the program code can be saved in a computer storage medium.

[0066] The embodiment of the present application provides a method for determining layout information of a scanning rod, and Figure 1 is a schematic diagram of an implementation process of a method for determining layout information of a scanning rod according to the embodiment of the present application, as shown in Figure 1, which comprises the following steps.

[0067] In step S101, user dental arch data is acquired, wherein an implant is installed on the user dental arch, and the implant is used to install the scanning rod.

[0068] In the embodiment of the present application, the dental arch data can be three-dimensional model data of the dental arch, and the electronic device can be communicatively connected with a digital impression instrument to form a three-dimensional scanning system, so that the user dental arch data is obtained through scanning and processing by the three-dimensional scanning system. In the embodiment of the present application, the implant can be installed on the dental arch, and then the digital impression instrument is used to scan the oral cavity. The device uses an optical sensor to capture image data in the oral cavity, and the dental arch data is generated by three-dimensional reconstruction of the image data in the oral cavity through the electronic device. The dental arch data can include three-dimensional topographic data of the dental arch, and the data of the implant is included in the dental arch data. The implant is used to install the scanning rod.

[0069] In step S102, a layout scheme of the scanning rod is determined based on the dental arch data.

[0070] In the embodiment of the present application, the layout scheme can include information such as the position, model, angle and spacing of the scanning rod.

[0071] In the embodiment of the present application, the neural network model can be used to determine the layout scheme of the scanning rod.

[0072] In some embodiments, step S102 can be implemented by the following steps.

[0073] In step S1021, position information of the implant on the dental arch is determined based on the dental arch data.

[0074] In the embodiment of the present application, the dental arch data can be input into computer software for analysis and processing, and through computer simulation, the position of the implant on the dental arch can be determined.

[0075] In the embodiment of the present application, when the computer is processing, the position information of the implant on the dental arch can be obtained by fitting a cylindrical surface with a plane based on the feature information of the implant through the intersection of the cylindrical axis.

[0076] In some embodiments, the dental arch data can be input into a pre-established neural network model to output the implant position information on the dental arch. In the embodiments of the present application, sample data can be collected, which can include dental arch data. Then the sample data is labeled, that is, the corresponding output data, that is, the implant position information on the dental arch, is provided for each sample data, to obtain a sample data set for training. Select an appropriate neural network structure and algorithm, such as a deep neural network (DNN) or a convolutional neural network (CNN), to adapt to the characteristics and complexity of the input data. Use the data set to train the neural network model, and continuously adjust the model parameters through the back propagation algorithm, so that it can accurately predict the implant position information on the dental arch. After training, the trained model can be verified using a validation set to evaluate its performance and optimize it to improve the accuracy and generalization ability of the model. Then the trained neural network model is deployed, and after the dental arch data is obtained, it can be input into the trained neural network model to output the implant position information on the dental arch.

[0077] In some embodiments, the dental arch data can be automatically matched with the feature information of EXOCAD to obtain the implant position information on the dental arch. When the dental arch data is automatically matched with the feature information of EXOCAD to obtain the implant position information, the dental arch data and the feature information of EXOCAD can be preprocessed to ensure that their formats and coordinate systems are consistent. Data alignment, coordinate system conversion and other operations are required. Use an automatic matching algorithm to match the dental arch data with the feature information of EXOCAD. When matching, you can choose feature point matching, surface matching, least squares fitting, etc. to determine the first position information of the implant on the dental arch.

[0078] FIG. 2 is a schematic diagram of determining position information according to an embodiment of the present application. As shown in FIG. 2, 1 corresponds to the position information of an implant.

[0079] In step S1022, the position information is input into the layout algorithm model of the scanning rod, and the layout scheme that meets the preset layout condition is determined as the layout scheme of the scanning rod.

[0080] In the embodiments of the present application, the preset layout condition includes an interference degree condition. The interference degree condition can be that there is no interference between the scanning rods in the layout scheme, which means that there is no collision between the scanning rods. In some embodiments, the interference degree condition can also be that there is interference, but the number of scanning rods with interference is the smallest, and in the case of the same number, the magnitude of the interference is the smallest.

[0081] In some embodiments, the preset layout condition further includes a loop layout condition. The layout scheme that meets the preset layout condition is the layout scheme that meets the loop layout condition.

[0082] In the embodiments of the present application, for the case of three or more scanning rods, the loop arrangement condition includes: any scanning rod is arranged adjacent to at least two other scanning rods, and the position of any scanning rod can be defined by reference to at least two other scanning rods, for example, the scanning rods are arranged in a ring shape, or a section of the scanning rods is arranged in a cluster, so as to meet the loop splicing requirement.

[0083] In the embodiments of the present application, the layout algorithm model can be an AI model. The layout algorithm model can be established in advance. A sample data set can be obtained, and the sample data set can be preprocessed, including data cleaning, labeling, format conversion, etc., to ensure the quality and consistency of the data, and then a deep learning model is designed. The deep learning module can include a neural network, a convolutional neural network (CNN), a recurrent neural network (RNN), etc., or a machine learning algorithm such as a support vector machine (SVM), a decision tree, etc. The deep learning model is trained through the preprocessed data, and the model parameters are repeatedly iterated and optimized to enable the deep learning model to accurately learn and predict the task of oral implant surgery layout. After the training is completed, the deep learning model can be deployed in an electronic device, so that the electronic device can determine the layout scheme that meets the preset arrangement condition as the layout scheme of the scanning rods after inputting the position information into the layout algorithm model.

[0084] In step S103, the layout scheme is output.

[0085] In the embodiments of the present application, the layout scheme can be displayed in the form of a two-dimensional plan view, and the position, angle, and spacing of the scanning rods can be clearly displayed. This display method is suitable for simple layout schemes and can intuitively display the layout of the scanning rods.

[0086] In some embodiments, the layout scheme can be converted into a three-dimensional model. By displaying the three-dimensional model, the position of the scanning rods and the oral structure can be more realistically displayed. Through the three-dimensional model, the spatial relationship between the scanning rods can be observed, helping users better understand the layout scheme.

[0087] In some embodiments, virtual reality technology can be used to present the layout scheme in a virtual environment, so that users can interact and simulate operations in real time in the virtual environment. This display method can improve the accuracy and visualization effect of the surgery planning.

[0088] In some embodiments, the layout scheme can be displayed through animation, which can vividly display the layout and adjustment process of the scanning rods. Animation display can help the surgical team better understand the process of layout algorithm and scheme design.

[0089] FIG. 3 is a schematic diagram of a layout scheme provided by an embodiment of the present application. As shown in FIG. 3, the position, angle, spacing, model, etc. of the scanning rods can be displayed in the layout scheme.

[0090] The method for determining layout information of a scanning rod provided in the embodiments of the present application comprises: acquiring dental arch data of a user, wherein the dental arch of the user is provided with implants, and the implants are used to install scanning rods; determining a layout scheme of the scanning rods based on the dental arch data, and outputting the layout scheme, so that the user can be guided to assemble according to the layout scheme, and the assembly efficiency can be improved.

[0091] In some embodiments, after step S103, the method further comprises:

[0092] Step S104: updating the layout scheme in response to an editing operation of the user on the layout scheme.

[0093] In the embodiments of the present application, the user can adopt the scheme provided by the layout algorithm model, or edit the layout scheme.

[0094] In the embodiments of the present application, editing the layout scheme comprises: adjusting the positions of the scanning rods, adjusting the models of the scanning rods, modifying the orientations of the connecting rods of the scanning rods, and the like. In some embodiments, editing the scheme can further comprise: free editing, in which the user can customize the correspondence between the implants and the scanning rods, freely select to simulate the assembly of the numbered scanning rods on the data implants, and rotate the orientations of the connecting rods of the scanning rods along the axes.

[0095] In some embodiments, the layout scheme can be displayed in a three-dimensional model or a two-dimensional model. When editing, the editing can be performed on the three-dimensional model or on a two-dimensional plane.

[0096] In some embodiments, after step S104, the method further comprises:

[0097] Step S105: determining whether the layout scheme updated by the editing operation satisfies an interference degree condition.

[0098] In the embodiments of the present application, it is determined whether the modified layout scheme satisfies the interference degree condition, for example, whether there is interference.

[0099] Step S106: when the layout scheme updated by the editing operation does not satisfy the interference degree condition, outputting first prompt information, wherein the first prompt information is used to prompt the user to perform an optimization operation on the layout scheme.

[0100] In the embodiments of the present application, if the layout scheme does not satisfy the interference degree condition, it means that there is interference between the scanning rods in the layout scheme.

[0101] In the embodiments of the present application, the first prompt information can be a text prompt, or the color of the interference position can be changed to output the first prompt information.

[0102] In the embodiments of the present application, the first prompt information is used to prompt the user to optimize the interference.

[0103] In some embodiments, after step S106, the method further includes:

[0104] Step S107, in response to the user's optimization operation on the layout scheme, the orientation of the connecting rod of the scanning rod is optimized to optimize the interference degree between the scanning rods updated by the editing operation.

[0105] In the embodiments of the present application, the optimization function option can be set in the interface, and the user can click the optimization function option, so that the electronic device obtains the optimization operation on the layout scheme, the electronic device can calculate the optimal orientation of the connecting rod, and then recalculate the distance and positional relationship between the scanning rods through the new connecting rod orientation information to ensure that there is no interference between the modified scanning rods. When the orientation of the connecting rod is optimized, the scanning rod and the implant position do not move, and only the connecting rod rotates.

[0106] In the embodiments of the present application, by optimizing the orientation of the connecting rod of the scanning rod, the modified layout scheme avoids interference during assembly.

[0107] In some embodiments, after step S107, the method further includes:

[0108] Step S108, determining whether the layout scheme updated by the optimization operation meets the interference degree condition;

[0109] Step S109, when the layout scheme updated by the optimization operation does not meet the interference degree condition, outputting suggestion information, the suggestion information is used to suggest the user to replace the corresponding relationship between the scanning rod and the implant.

[0110] In the embodiments of the present application, if there is interference between the optimized scanning rods, it means that the optimization fails, and at this time the user is suggested to replace the corresponding relationship between the scanning rod and the implant.

[0111] In some embodiments, after step S1022, the method further includes:

[0112] Step S1023, in the case that the layout scheme does not meet the interference degree condition, outputting second prompt information, the second prompt information is used to prompt the user to perform batch layout.

[0113] In the embodiments of the present application, if no layout scheme is generated, it means that there is interference between the scanning rods, and the batch layout can include determining the layout scheme in batches.

[0114] In the embodiments of the present application, the second prompt information can be output through voice or text.

[0115] In some embodiments, after step S1022, the method further includes:

[0116] In step S1024, when the arrangement scheme does not satisfy the interference degree condition, a batch layout scheme is formed based on the arrangement scheme, and the batch layout scheme is determined as the layout scheme of the scanning rods.

[0117] In the embodiment of the present application, the arrangement scheme can be input into the batch layout model to obtain the batch layout scheme. The batch layout scheme is the layout scheme of the scanning rods.

[0118] In some embodiments, after step S1024, the method further comprises:

[0119] In step S1025, a target scanning rod with interference in the arrangement scheme is determined, and the target scanning rod includes a first scanning rod and a second scanning rod.

[0120] The first layout scheme and the second layout scheme are generated based on the target scanning rod, the first layout scheme is generated based on the arrangement scheme and the second scanning rod, and the second layout scheme is generated based on the arrangement scheme and the first scanning rod.

[0121] In the embodiment of the present application, the first layout scheme does not include the second scanning rod, and the second layout scheme does not include the first scanning rod.

[0122] In the embodiment of the present application, the first layout scheme is generated by removing the second scanning rod based on the arrangement scheme, and the second layout scheme is generated by removing the first scanning rod based on the arrangement scheme.

[0123] For example, the user is a patient with a half-mouth edentulous jaw, and there are six implants in the lower jaw, wherein the distance between two implants 2 and 3 does not satisfy the condition of simultaneously installing the upper scanning rod. The interference condition after simulation assembly is displayed to the user.

As shown in FIG. 4, the scanning rod corresponding to 2 is the first scanning rod, and the scanning rod corresponding to 3 is the second scanning rod.

[0124] In the embodiment of the present application, the first layout scheme can be obtained based on the second scanning rod and the scanning rods corresponding to other bases. The second layout scheme can be obtained based on the first scanning rod and the scanning rods other than the first scanning rod.

[0125] Based on the above example, the first layout scheme can be the scanning rods corresponding to 1, 2, 4, 5, and 6, and the second layout scheme can be the scanning rods corresponding to 1, 3, 4, 5, and 6. FIG. 5 is a schematic diagram of a first layout scheme provided by an embodiment of the present application. As shown in FIG. 5, there is no scanning rod corresponding to 3 in the first layout scheme. FIG. 6 is a schematic diagram of a second layout scheme provided by an embodiment of the present application. As shown in FIG. 6, there is no scanning rod corresponding to the second position in the second layout scheme.

[0126] The method provided in the embodiments of the present application can be directly generated when the typesetting algorithm model can generate a typesetting scheme, and can be generated in batches if the typesetting algorithm model cannot generate a typesetting scheme.

[0127] In some embodiments, the method further comprises:

[0128] In step S110, a scanning path is determined based on the typesetting scheme.

[0129] In the embodiments of the present application, the typesetting scheme can be input into a pre-established path planning model to determine the scanning path.

[0130] In the embodiments of the present application, the typesetting scheme of the scanning rod includes position, orientation and other information input into the pre-established path planning model. According to the input typesetting scheme of the scanning rod, the path planning model will perform calculation and optimization of the path planning algorithm to determine the scanning path and avoid repeated scanning or missed scanning. The path planning model will consider the positional relationship between the scanning rods, the continuity of the scanning path and the coverage area and other factors to optimize the scanning path, so as to improve the scanning efficiency and accuracy. According to the optimal scanning path calculated by the path planning model, a final scanning path scheme is generated, including the moving trajectory and scanning sequence of the scanning rod, for the user to perform actual scanning operation.

[0131] In step S118, the scanning path is output.

[0132] In the embodiments of the present application, the scanning path can be displayed through a display device. The user can be guided in the scanning process in the display interface. The display in the interface can be a dynamic model indicating the scanning path, or a curve planning the scanning path.
