Description

Technical Field

[0001] The present application relates to the field of scanning processing technology, and in particular to a data scanning method, device, electronic device and storage medium for an implant. Background Art

[0002] In the related art, in order to fit the denture in the oral cavity, it is necessary to design the denture based on the splicing data of the scanning rod and the gums. The existing scanning solution is to first install the scanning cap on the composite base in the patient's oral cavity, obtain the first scanning data with the scanning cap and gums through three-dimensional scanning, and then replace the scanning rod with the scanning cap, and then scan the scanning rod to obtain the scanning data of the scanning rod. Since the first scanning data with the scanning cap and the scanning data of the scanning rod are collected twice, the two are not in the same coordinate system. Therefore, the existing scanning solution needs to convert the scanning data of the scanning rod into scanning cap data, and then splice it with the first scanning data with gums to obtain the splicing data of the scanning rod and gums, which makes the scanning process complicated and cumbersome. In addition, the existing scanning solution needs to install the scanning cap and the scanning rod in the patient's oral cavity twice, which leads to an increase in scanning costs, and due to the small oral environment, installing the scanning cap and the scanning rod twice will also cause physical discomfort to the patient.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art in the technical field in this application. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. It should be understood that, unless otherwise specified in this application, "at least one" refers to one or more. "Multiple" refers to two or more than two. For example, at least one of a, b or c can represent: a, b, c, a and b, a and c, b and c, a, b and c seven situations.

[0030] In the related art, in order to fit the denture in the oral cavity, it is necessary to design the denture based on the splicing data of the scanning rod and the gums. The existing scanning scheme is to first install the scanning cap on the composite base in the patient's oral cavity, obtain the first scanning data with the scanning cap and gums through three-dimensional scanning, and then replace the scanning rod with the scanning cap, and then scan the scanning rod to obtain the scanning data of the scanning rod. Since the first scanning data with the scanning cap and the scanning data of the scanning rod are collected twice, the two are not in the same coordinate system. Therefore, the existing scanning scheme needs to convert the scanning data of the scanning rod into scanning cap data, and then splice the converted scanning cap data with the first scanning data with gums to obtain the splicing data of the scanning rod and gums, which makes the scanning process complicated and cumbersome. In addition, the existing scanning scheme needs to install the scanning cap and the scanning rod in the patient's oral cavity twice, which leads to an increase in scanning costs, and due to the small oral environment, installing the scanning cap and the scanning rod twice will also cause physical discomfort to the patient.

[0031] The embodiments of the present application provide a data scanning method, device and storage medium to solve the problems of complicated implant scanning process, high scanning cost and easy discomfort to users.

[0032] Figure 1 This is a flow chart of a data scanning method provided in an embodiment of the present application, and the data scanning method is applied in an electronic device. Figure 1 The method of the example includes one or more steps, but does not constitute a limitation of the present application. In addition, the order of the steps of the method is only an example, and the order of the steps can be changed. Additional steps can be added or steps can be reduced without departing from the content disclosed in the present application. The method includes the following steps.

[0033] S101, acquiring first scanning data of an oral cavity in a first state, wherein the oral cavity in the first state refers to an oral cavity in which at least one abutment is implanted, and the first scanning data includes initial abutment data and gum data.

[0034] In some embodiments of the present application, in a first state, at least one implant is installed on the gums of the patient's mouth, and an abutment is installed on the corresponding implant. The implant is an artificial tooth root used to replace missing teeth, which can be made of titanium alloy or ceramic material to become a support for the implant. The abutment is the part of the implant system used to support and fix the implant superstructure. The abutment is composited from a variety of materials through a special process. For example, the abutment can be made of titanium alloy or pure titanium as a substrate, and the surface is covered with ceramic or polymer materials. In some embodiments of the present application, the abutment can be an ordinary abutment or a composite abutment.

[0035] After the abutment is installed in the oral cavity, the abutment and gums in the oral cavity can be scanned by an oral scanning device to obtain first scanning data, which includes initial abutment data and gum data. Figure 2 As shown, the initial abutment data may include three-dimensional data of the abutment. The three-dimensional data of the abutment may be data of the shape and structure of the part of the abutment exposed to the gums, including information such as thickness, shape, color, and texture. In some embodiments of the present application, the abutment may be three-dimensionally scanned by a small line segment scanning method to obtain small line segment scanning data, and the three-dimensional data of the abutment may be obtained based on the small line segment scanning data. The embodiment of the present application uses a small line segment scanning method to scan the abutment and gums in the oral cavity, and the initial abutment data may be obtained quickly and accurately.

[0036] In some embodiments of the present application, the gum data includes three-dimensional gum data. The three-dimensional gum data refers to data of the three-dimensional shape and structure of gum tissue, and may include information such as gum thickness, shape, color, and texture.

[0037] S102, obtaining second scanning data of the oral cavity in a second state, wherein the oral cavity in the second state refers to a base in the oral cavity installed with a corresponding scanning rod, and the second scanning data includes scanning rod data.

[0038] In some embodiments of the present application, in the second state, a scanning rod is installed on the base of the patient's mouth. The scanning rod is a device used for oral scanning, mainly used for three-dimensional scanning inside the oral cavity. Marking points are set on the scanning rod. Marking points are some specific points or marks on the scanning rod, which can be bright or colored points. There are multiple marking points or coding points on a scanning rod, which are distributed at different positions of the scanning rod to provide sufficient information to determine the position and posture of the scanning rod. After the scanning rod is installed in the oral cavity, the scanning rod is scanned by the scanning device to obtain the second scanning data (reference Figure 3 , code points not shown).

[0039] In some embodiments of the present application, obtaining second scanning data of the oral cavity in the second state includes: obtaining a landmark point image of the inner surface of the oral cavity, extracting landmark points from the landmark point image, and performing three-dimensional reconstruction of the landmark points, obtaining three-dimensional data of the landmark points, and determining scanning rod data based on the three-dimensional data of the landmark points, wherein the scanning rod data includes position information of each scanning rod and landmark point information on each scanning rod.

[0040] S103, determining a first conversion relationship between the scanning rod data and the target base data in the second scanning data.

[0041] refer to Figure 4 FIG. 1 is a flowchart of a method for determining a first conversion relationship between scanbar data and target base station data in some embodiments of the present application. The method includes the following steps.

[0042] S401, determining identification information of the scanning rod according to the marking point information on each scanning rod.

[0043] In some embodiments of the present application, different scanning rods have different marking point information. The identification information of the corresponding scanning rod can be determined according to the marking point information on each scanning rod. In some embodiments of the present application, the identification information of the scanning rod is used to identify the identity of the scanning rod, for example, the identification information of the scanning rod can be a string of numbers and letters.

[0044] S402: Determine a first conversion relationship between the scanning rod data and the target base station data in the second scanning data according to a preset binding relationship between the scanning rod and the base station and identification information of the scanning rod.

[0045] In some embodiments of the present application, determining the first conversion relationship between the scanning rod data and the target base data in the second scanning data according to the preset binding relationship between the scanning rod and the base and the identification information of the scanning rod includes: determining the model of the base corresponding to each scanning rod according to the preset binding relationship between the scanning rod and the base and the identification information of the scanning rod; retrieving the first standard base model corresponding to each scanning rod from the base database according to the model of the base corresponding to each scanning rod; combining the first standard base model and the position information of each scanning rod into target base data according to the binding relationship between the scanning rod and the base and the identification information of the scanning rod, and determining the first conversion relationship between the scanning rod data and the target base data in the second scanning data.

[0046] In some embodiments of the present application, the preset binding relationship is the corresponding relationship set when the user opens a scanning order to scan the scanning rod and the base, and the base database includes standard base models of different types of bases. For example, the preset binding relationship can be that scanning rod A corresponds to base a, scanning rod B corresponds to base b, scanning rod C corresponds to base c, and scanning rod D corresponds to base d. If the identification information of the scanning rod is A, then the type of the corresponding base can be determined as base a based on the identification information A of the scanning rod; based on base a, the standard base model corresponding to base a is retrieved from the base database, and the obtained standard base model is used as the first standard base model corresponding to scanning rod A. In this embodiment, the process of determining the corresponding first standard base model according to scanning rods B, C, and D is the same as the process of determining the first standard base model according to scanning rod A, and will not be repeated here. After determining the first standard base model corresponding to bases a, b, c, and d, the first standard base model corresponding to bases a, b, c, and d and the position information of scanning rods A, B, C, and D are combined into target base data (reference Figure 5 As shown), thereby determining the first conversion relationship between the scanning rod data and the target base data in the second scanning data.

[0047] S104, based on the initial base data and the target base data, and the first conversion relationship between the scanning rod data and the target base data, the first scanning data and the second scanning data are processed to obtain a target three-dimensional model.

[0048] refer to Figure 6 FIG. 1 is a flow chart of a method for processing first scan data and second scan data in an embodiment of the present application. The method includes the following steps.

[0049] S601, determining a second conversion relationship between target base station data and initial base station data according to actual scanning models of each base station and a first standard base station model in the target base station data.

[0050] In some embodiments of the present application, the actual scanned model of each abutment is the outer surface data of the abutment exposed to the gums in the initial abutment data.

[0051] In some embodiments of the present application, a second conversion relationship between the target base station data and the initial base station data is determined based on an actual scanning model of each base station and a first standard base station model in the target base station data, including: retrieving a second standard base station model corresponding to each base station from a base station database based on the actual scanning model of each base station; combining each second standard base station model with the initial position information of each base station to form intermediate base station data, and using the initial position information of each base station as the final position information of each second standard base station model; determining the second conversion relationship between the target base station data and the initial base station data based on the corresponding relationship between the second standard base station model in the intermediate base station data and the first standard base station model in the target base station data and the second standard base station model in the intermediate base station data and each base station in the initial base station data.

[0052] In some embodiments of the present application, the base station database includes the correspondence between the actual scanning model of different base stations and the standard base station model. Based on the actual scanning model of the base station, the standard base station model corresponding to the actual scanning model of the base station can be retrieved from the base station database as the second standard base station model corresponding to the actual scanning model of the base station. In some embodiments of the present application, it is also possible to retrieve the corresponding standard base station model from the base station database as the second standard base station model corresponding to the actual scanning model of the base station according to whether there is a model in the base station database that coincides with the outer surface structure of the gums exposed outside the base station. In some embodiments of the present application, the base station includes a screw hole aperture, and it is determined whether there is a model in the base station database that coincides with the screw hole aperture of the actual scanning model, and the corresponding standard base station model is retrieved from the base station database as the second standard base station model corresponding to the actual scanning model of the base station. In some embodiments of the present application, the model in the base station database can also be screened according to the shape and size in the actual scanning model to determine the second standard base station model. The process of determining the second standard base station model according to the shape and size and the process of determining the second standard base station model according to the screw hole aperture are not described in detail here.

[0053] After determining the second standard abutment model of each abutment in the initial abutment data, all the second standard abutment models and the initial position information of all the abutments are combined into intermediate abutment data, wherein the initial position information of each abutment is used as the final position information of the second standard abutment model of the corresponding abutment. For example, the abutments in the initial abutment data include four abutments, i.e., a, c, b, and d. Based on the actual scanning model of abutment a, the standard abutment model corresponding to the actual scanning model of abutment a can be retrieved from the abutment database as the second standard abutment model corresponding to the actual scanning model of abutment a. According to the above method of obtaining the second standard abutment model corresponding to the actual scanning model of abutment a, the corresponding second standard abutment models of the remaining abutments c, b, and d in the initial abutment data are obtained. After obtaining the second standard abutment models of a, c, b, and d, all the obtained second standard abutment models and the initial position information of a, c, b, and d are combined into intermediate abutment data.

[0054] In some embodiments of the present application, based on the second standard base station model in the intermediate base station data and the first standard base station model in the target base station data, and the correspondence between the second standard base station model in the intermediate base station data and each base station in the initial base station data, the second conversion relationship between the target base station data and the initial base station data can be determined. Because the second standard base station model in the intermediate base station data and the first standard base station model in the target base station data are both standard parts with completely identical structures, the correspondence between the two can be determined by comparing the external surface or structure, thereby improving the accuracy and efficiency of determining the second conversion relationship.

[0055] In some embodiments of the present application, through the second conversion relationship, the initial position information of the base in the initial base data is replaced with the position information of the base in the corresponding target base data (position information of the scanning rod), thereby achieving correction of the initial base data.

[0056] S602, according to the second conversion relationship and the first conversion relationship between the scanbar data and the target base data in the second scan data, the target base data, the scanbar data, and the gum data are spliced ​​to obtain a target three-dimensional model.

[0057] In some embodiments of the present application, the first target base data corresponding to the initial base data in the first scan data can be determined based on the second conversion relationship; the second target base data corresponding to the scanbar data of the second scan data can be determined based on the first conversion relationship; based on the first target base data and the second target base data, the first target base data, the second target base data, the scanbar data, and the gum data are spliced ​​to obtain a target three-dimensional model (reference Figure 7 as shown).

[0058] In some embodiments of the present application, the method further includes: generating a denture model according to the target three-dimensional model and sending the denture model to a 3D printing device; receiving a user request for modifying the denture model in real time; and outputting a revised three-dimensional denture model according to the user request and the target three-dimensional model. In the embodiment of the present application, a revised three-dimensional denture model can be output according to the user request and the target three-dimensional model, so that the user can set dentures of different quantities, sizes and shapes and better meet the user's needs.

[0059] In some embodiments of the present application, the method further includes: displaying the target base data. In some embodiments of the present application, the target base data is displayed in real time on the interactive interface when the second scan data of the oral cavity in the second state is obtained. In another embodiment of the present application, after the second scan data of the oral cavity in the second state is obtained, the target base data is displayed in response to the user's switching instruction. In this way, after the user completes the scan, the standard base structure and the corrected position information (the position information of the scanning rod) can be seen in response to the user's needs, so that the user can make an analysis based on this.

[0060] In some embodiments of the present application, the method further includes: when acquiring the second scan data of the oral cavity in the second state, displaying the information of the marking points on each scanning rod in real time on the interactive interface; when determining the identification information of the scanning rod, calling up the standard scanning rod model of the scanning rod for display. By displaying the standard scanning rod model, the embodiment of the present application can facilitate the user to respond to the user's needs during the process of scanning the oral cavity with the scanning rod installed or after the scanning is completed, and quickly see the standard scanning rod structure, thereby improving the user experience.

[0061] In some embodiments of the present application, the method further includes: displaying the intermediate base data in real time on the interactive interface when acquiring the first scan data of the oral cavity in the first state, or, after acquiring the first scan data of the oral cavity in the first state, displaying the intermediate base data in response to a user's switching instruction. In this way, the user's needs can be responded to during the process of the user scanning the oral cavity with the base installed or after the scanning is completed, and the standard base structure can be quickly seen, thereby improving the user experience.

[0062] The embodiment of the present application is based on the first conversion relationship between the initial base data and the target base data, and the scanning rod data and the target base data, and processes the initial base data, gum data in the first scanning data and the scanning rod data in the second scanning data to obtain a target three-dimensional model, thereby splicing the gum data and the scanning rod data based on the first conversion relationship, that is, the fusion data of the gums and the scanning rod can be obtained. Therefore, the data scanning method of the present application does not need to install a scanning cap in the patient's mouth and determine the fusion data of the gums and the scanning rod based on the scanning data of the scanning cap, thereby reducing the scanning cap equipment required for scanning, saving costs, and reducing the process of scanning the scanning cap, thereby improving scanning efficiency.
