Description

Technical Field

[0001] This disclosure relates to the field of data processing technology, and in particular to a method, apparatus, device and medium for generating profile lines of a dental model. Background Technology

[0002] Currently, user dental data is generally archived and stored using plaster models. If a scanner is available, the plaster model is scanned and stored as a digital model.

[0003] However, due to the inconvenience of model acquisition, there are relatively few models from different periods for the same user. This makes it difficult for doctors to observe two different sets of model data to see the differences between the models. Even if manual observation is possible, the efficiency and accuracy are relatively poor. In addition, even with intraoral scan models available, there is a lack of software for model comparison. Summary of the Invention

[0004] To solve the above-mentioned technical problems, or at least partially solve them, this disclosure provides a method, apparatus, device, and medium for generating profile lines of a dental model.

[0028] Figure 1 This is a flowchart illustrating a method for generating profile lines of a dental model according to an embodiment of this disclosure. The method can be executed by a dental model profile line generation device, which can be implemented using software and / or hardware, and is generally integrated into an electronic device. Figure 1 As shown, the method includes:

[0029] Step 101: Display the first and second dental models to be compared.

[0030] Among them, the first and second dental models to be compared refer to two sets of maxillary and mandibular dental models.

[0031] In this embodiment, two sets of maxillary and mandibular dental models to be compared can be selected and registered and aligned according to the application scenario to obtain a first dental model to be compared and a second dental model to be compared. In one specific embodiment, a first dental model (e.g., a first maxillary and mandibular dental model) of the user at a first time point is obtained, and a second dental model (e.g., a second maxillary and mandibular dental model) of the user at a second time point is obtained. The second time point is different from the first time point. The first and second dental models are registered and aligned based on a preset registration and alignment algorithm to obtain the first dental model to be compared and the second dental model to be compared. The dental model may only include teeth.

[0032] For example, for each set of dental models, the region of each tooth is first identified by artificial intelligence, and then the dental models are aligned according to the tooth identification information. After the alignment of each set of dental models is completed, the two sets of dental models are aligned and adjusted, for example, by using the ICP (Iterative ClosestPoint) model registration method, to obtain the first and second dental models to be compared after registration and alignment.

[0033] Understandably, there are many ways to display the first and second dental models to be compared, and the settings can be selected according to the application scenario. As an example of an application scenario, the user's trigger operation on the display page can be detected. When the user clicks or hovers over the display controls for the first and second dental models to be compared, the display trigger operation for the first and second dental models to be compared can be received, and thus the first and second dental models to be compared can be displayed. For example, clicking the model display control 1 will display the pre-registered and aligned first and second dental models to be compared, M1. Or, clicking the model display control 2 will display the pre-registered and aligned first and second dental models to be compared, M2.

[0034] Step 102: Based on the preset cross-sectional position, display the cross-sectional screenshots of the first and second dental models to be compared, so as to determine the comparison results of the first and second dental models to be compared based on the cross-sectional screenshots.

[0035] The cross-sectional position can be selected and set according to the application scenario. In a specific embodiment of this disclosure, the preset cross-sectional position is the midline of the jaw.

[0036] Among them, the section line screenshot refers to the screenshot of the section outline of the two sets of dental models at this section position.

[0037] In this embodiment of the disclosure, after displaying the cross-sectional screenshots of the first and second dental models to be compared, the comparison results of the first and second dental models to be compared can be determined based on the cross-sectional screenshots. For example, tooth wear can be determined based on the straight-line distance between each point on the cross-sectional outline in the cross-sectional screenshot. Specifically, each comparison point is selected according to the application scenario to obtain the corresponding comparison results.

[0038] The dental model section line generation scheme provided in this disclosure displays a first and a second dental model to be compared. Based on a preset section position, it displays section line screenshots of the first and second dental models to be compared, so as to determine the comparison result of the first and second dental models to be compared based on the section line screenshots. Using the above technical solution, section line screenshots can be generated during dental model comparison, allowing the comparison result of the two dental models to be compared to be determined through section line screenshots when comparing two sets of dental models. This provides a precise understanding of changes in tooth position and morphology, improving the accuracy of dental model comparison.

[0039] Based on the foregoing embodiments, with the widespread use of intraoral scanning devices, acquiring data from a user's mouth has become simple and quick. After acquiring data from the user's mouth over a certain period, comparative analysis of two sets of models can be performed. By providing cross-sectional screenshots during model comparison, the changes in the position and shape of the teeth in the user's mouth can be accurately understood through functions such as cross-sectional screenshots and cross-sectional contour measurements when comparing two sets of models.

[0040] Specifically, Figure 2 This is a flowchart illustrating another method for generating profile lines of a dental model according to an embodiment of this disclosure. This embodiment further optimizes the aforementioned method for generating profile lines of a dental model based on the previous embodiment. Figure 2 As shown, the method includes:

[0041] Step 201: Obtain the user's first dental model at the first time point and the user's second dental model at the second time point; wherein the second time point is different from the first time point, the first dental model and the second dental model are registered and aligned based on a preset registration and alignment algorithm to obtain the first dental model to be compared and the second dental model to be compared.

[0042] The first and second time points can be selected according to the comparison needs. For example, the first and second time points can be spaced one year apart. The registration and alignment algorithm can also be selected according to the application scenario, such as the nearest point iteration algorithm.

[0043] Step 202: Display the first and second dental models to be compared.

[0044] After step 202, steps 203 and / or 204 and / or 205 and / or 206 can be executed. The execution order of steps 203-206 can be determined according to the actual situation. Figure 2 This is just an example.

[0045] Step 203: Based on the midline position of the jaw, display the cross-sectional screenshots of the first and second jaw models to be compared.

[0046] For example, Figure 3 This is a schematic diagram illustrating an information display provided in an embodiment of the present disclosure, such as... Figure 3 As shown, it includes a first tooth model 11 to be compared, a second tooth model 12 to be compared, and a cross-sectional screenshot 13. That is, when comparing two sets of tooth data, the cross-sectional screenshot function is turned on. The cross-sectional screenshot is taken at the midline of the tooth by default. Figure 3 The bottom right corner displays cross-sectional views of the two models at this midline position of the jaw.

[0047] Step 204: Receive the trigger operation of the section position adjustment control, determine the section update position, and display the section line update screenshots of the first and second tooth jaw models to be compared based on the section update position.

[0048] Specifically, the section position can be adjusted, meaning the section interface can be repositioned. The section can be dragged along the dental arch line, and the orientation of the section can be rotated. During operation, the section line screenshot is updated in real time. Figure 4 As shown.

[0049] Step 205: Receive an operation request for the section line screenshot, and perform operation processing on the section line screenshot based on the operation request.

[0050] The operation settings can be selected according to the application scenario, such as panning, zooming, etc., to further meet the user's needs.

[0051] Step 206: Receive a selection request for the profile screenshot, determine and display the first and second measurement endpoints based on the selection request, and determine and display the measurement distance based on the first and second measurement endpoints.

[0052] Optionally, the first and second measurement endpoints lie on the outline of the profile view.

[0053] For example, Figure 5 A schematic diagram of a cross-sectional view provided in an embodiment of this disclosure, such as... Figure 5 As shown, straight-line measurements can be performed on section line screenshot 13 to measure the distance from one point to another on the section outline. The measurement endpoint can be dragged, and it will always remain on the outline. For example... Figure 3The first measurement endpoint A and the second measurement endpoint B shown are either Figure 5 The first measurement endpoint C and the second measurement endpoint D are shown.

[0054] The dental model profile generation scheme provided in this embodiment obtains a first dental model of the user at a first time point and a second dental model of the user at a second time point. The second time point is different from the first time point. Based on a preset registration and alignment algorithm, the first and second dental models are registered and aligned to obtain a first and a second dental model to be compared. The first and second dental models to be compared are displayed. Based on the dental midline position, a profile screenshot of the first and second dental models to be compared is displayed. A trigger operation on the profile position adjustment control is received, and the profile update position is determined. Based on the updated profile position, an updated profile screenshot of the first and second dental models to be compared is displayed. An operation request for the profile screenshot is received, and the profile screenshot is processed based on the operation request. A selection request for the profile screenshot is received, and a first and a second measurement endpoint are determined and displayed based on the selection request. A measurement distance is determined and displayed based on the first and second measurement endpoints. By adopting the above technical solution, it is possible to more accurately view and measure the contour differences and the amount of differences in different regions of the model, improve the accuracy of the generation of dental model section lines, update section line screenshots at different section positions to meet user needs, and perform related operations on section line screenshots to further enhance the user experience.
