[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the invention.
[0025] like Figure 1 The diagram shown is a flowchart illustrating the oral cavity positioning method based on one-time printing calibration technology in an embodiment of the present invention.
[0026] The oral cavity localization method based on one-time printed calibration technology includes:
[0027] Step S101: Based on the first positioning mark of the corresponding occlusal bracket identified, establish the spatial positional relationship between the patient's jawbone wearing the occlusal bracket and the occlusal bracket; wherein, the first positioning mark is printed on the surface of the first locator set on the occlusal bracket.
[0028] In an embodiment, the establishing the spatial position relationship between the patient's dentition wearing the bite bracket and the bite bracket based on the identified first positioning mark of the corresponding bite bracket comprises: obtaining bite bracket positioning point information from the collected patient oral image information based on the identified first positioning mark of the corresponding bite bracket; and establishing the spatial position relationship between the patient's dentition wearing the bite bracket and the bite bracket according to the dentition position information corresponding to the patient's dentition and the bite bracket positioning point information; wherein the bite bracket positioning point information is the spatial position information corresponding to the first positioner arranged on the bite bracket; the dentition position information is the spatial position information corresponding to the patient's dentition; and the bite bracket positioning point information and the dentition position information are obtained from the collected patient oral image information.
[0029] In an embodiment, the establishing the spatial position relationship between the patient's dentition wearing the bite bracket and the bite bracket according to the dentition position information corresponding to the patient's dentition and the bite bracket positioning point information comprises: obtaining the relative position relationship between the bite bracket and the patient's dentition according to the dentition position information corresponding to the patient's dentition and the bite bracket positioning point information; and establishing the spatial position relationship between the patient's dentition wearing the bite bracket and the bite bracket according to the relative position relationship between the bite bracket and the patient's dentition.
[0030] In an embodiment, the patient oral image information is collected by CT scanning the patient wearing the bite bracket; the bite bracket positioning point information is obtained from the collected patient oral image information based on the identified first positioning mark of the corresponding bite bracket; the dentition position information corresponding to the patient's dentition is obtained from the collected patient oral image information; and the spatial position relationship between the patient's dentition wearing the bite bracket and the bite bracket is established according to the bite bracket positioning point information and the dentition position information; wherein the patient oral image information is CT data information obtained by CT scanning the patient wearing the bite bracket; the bite bracket positioning point information is obtained from the CT data information obtained by scanning; and the dentition position information is obtained from the CT data information obtained by scanning.
[0031] Specifically, before CT scanning, a first positioning mark is printed on a first positioner arranged on the bite support. After the patient wears the bite support, CT scanning is performed on the oral region of the patient to obtain CT data information corresponding to the oral cavity of the patient. During the CT scanning, the first positioning mark can also be scanned. The bite support positioning point information corresponding to the first positioning mark can be obtained from the CT data information of the oral cavity of the patient. Then, according to the bite support positioning point information and the dental bed information corresponding to the dental bed of the patient obtained from the CT data, the relative positional relationship between the bite support and the dental bed of the patient is obtained, so that the spatial positional relationship between the dental bed of the patient and the bite support is established according to the relative positional relationship between the bite support and the dental bed of the patient.
[0032] It should be noted that the spatial positional relationship between the dental bed of the patient and the bite support obtained directly from the CT data can save a large amount of surgical preparation time.
[0033] Step S102: determining the spatial positional relationship between the dental bed of the patient and the implant mobile phone based on the identified second positioning mark corresponding to the implant mobile phone and the first positioning mark corresponding to the bite support, and according to the spatial positional relationship between the dental bed of the patient and the bite support, to supply mutual positioning between the dental bed of the patient and the implant mobile phone; wherein the second positioning mark is printed on the surface of the second positioner arranged on the implant mobile phone.
[0034] In an embodiment, determining the spatial positional relationship between the dental bed of the patient and the implant mobile phone based on the identified second positioning mark corresponding to the implant mobile phone and the first positioning mark corresponding to the bite support, and according to the spatial positional relationship between the dental bed of the patient and the bite support includes: calculating the spatial positional relationship between the bite support and the implant mobile phone based on the identified second positioning mark corresponding to the implant mobile phone and the first positioning mark corresponding to the bite support; determining the spatial positional relationship between the dental bed of the patient and the implant mobile phone based on the spatial positional relationship between the bite support and the implant mobile phone and the spatial positional relationship between the dental bed of the patient and the bite support, to supply mutual positioning between the dental bed of the patient and the implant mobile phone.
[0035] In an embodiment, calculating the spatial positional relationship between the bite support and the implant mobile phone based on the identified second positioning mark corresponding to the implant mobile phone and the first positioning mark corresponding to the bite support includes: calculating the spatial positional relationship between the bite support and the implant mobile phone based on the position information of the corresponding implant mobile phone determined according to the second positioning mark and the position information of the corresponding bite support determined according to the first positioning mark by referring to the Apriltag technology.
[0036] The method of calculating the spatial positional relationship between the occlusal bracket and the implant handset will be explained in detail below:
[0037] In the operation, the position information of the corresponding implant handset is calculated based on the second positioning mark of the corresponding implant handset identified in real time through the Apriltag technology. The position information of the corresponding occlusal bracket is calculated based on the first positioning mark of the corresponding occlusal bracket identified in real time through the Apriltag technology, and then the spatial positional relationship between the occlusal bracket and the implant handset is calculated according to the calculated position information of the corresponding implant handset and the position information of the corresponding occlusal bracket. Then, according to the spatial positional relationship between the patient's dental bed and the occlusal bracket obtained before the operation and the calculated spatial positional relationship between the occlusal bracket and the implant handset, the spatial positional relationship between the patient's dental bed and the implant handset can be determined for mutual positioning between the patient's dental bed and the implant handset.
[0038] It should be noted that the Apriltag technology is a high-efficiency two-dimensional code recognition technology, which can quickly and accurately identify two-dimensional codes under high-speed movement and low light conditions. The principle of Apriltag is to analyze the black and white pixels in the image to identify the position and direction of the two-dimensional code, thereby realizing the recognition of the two-dimensional code. The recognition process of Apriltag is divided into two steps: detection and decoding. In the detection stage, Apriltag will perform binaryzation processing on the image to separate the black and white pixels in the image. Then, Apriltag will analyze each pixel in the image to find the black and white boundary, thereby determining the position and direction of the two-dimensional code. In the decoding stage, Apriltag will decode the two-dimensional code to convert the information in the two-dimensional code into numbers or characters. The advantage of Apriltag is that it can quickly and accurately identify two-dimensional codes under high-speed movement and low light conditions, and Apriltag can also identify multiple two-dimensional codes to realize multi-target tracking.
[0039] The first locator, the second locator and the corresponding positioning marks mentioned in the above method will be explained in detail below in conjunction with the embodiments:
[0040] In an embodiment, the first locator is arranged at the end of the occlusal bracket, and the second locator is arranged at the end of the implant handset. It should be noted that arranging the first locator at the end of the occlusal bracket and the second locator at the end of the implant handset facilitates printing the first positioning mark and the second positioning mark, and facilitates identifying the first locator and the second locator. Moreover, it can also avoid occlusion and leave a space for the doctor to operate.
[0041] In an embodiment, the first locator and the second locator adopt a PC plastic cylindrical holder. The PC plastic has the advantage of being light and not interfering with fixation. The cylindrical holder can eliminate the visual dead angle when tracking the two-dimensional code using the Apriltag technology, and the first locator and the second locator can still be accurately identified after being transformed to any position and angle.
[0042] In an embodiment, the first positioning mark corresponding to the occlusal support and the second positioning mark corresponding to the implant handset adopt two-dimensional codes with different value ranges. For example, the two-dimensional code can be a pattern as shown in the following figure. Figure 2 The two-dimensional codes with different value ranges can distinguish the first locator arranged on the occlusal support from the second locator arranged on the implant handset in the identification process.
[0043] In an embodiment, the first locator is attached with a first label part, the surface of the first label part is printed with the first positioning mark, the second locator is attached with a second label part, and the surface of the second label part is printed with the second positioning mark. The first label part and the second label part adopt a flexible material, which can be paper, polyvinyl alcohol (PVA), polyester (PET), polyimide (PI), polyethylene naphthalate glycol (PEN), textile material, and the like, which are not listed here.
[0044] Specifically, the first positioning mark can be printed on the surface of a flexible material, and the flexible material can be attached to the surface of the first locator. The second positioning mark can be printed on the surface of another flexible material, and the flexible material can be attached to the surface of the second locator.
[0045] In an embodiment, the first positioning mark is printed on the surface of the first locator and the second positioning mark is printed on the surface of the second locator by a direct printing method. The direct printing method includes directly printing the first positioning mark and the second positioning mark on the surface of the corresponding locator by laser marking technology.
[0046] Specifically, the first positioning mark can be directly printed on the surface of the first locator by laser marking technology, and the second positioning mark can be directly printed on the surface of the second locator by laser marking technology.
[0047] It should be noted that laser marking technology is a new type of marking process that is non-contact, pollution-free and non-destructive. It integrates laser technology, computer technology and mechatronics technology, and is currently the most widely used advanced manufacturing technology in laser processing technology. The principle of laser marking is to use high-energy density laser to locally irradiate the workpiece, so that the surface layer of the material is vaporized or undergoes a chemical reaction to change color, thereby leaving a permanent mark.
[0048] It should be noted that the two printing methods described above can be selected by those skilled in the art according to actual needs to meet the accuracy requirements.
[0049] Similar to the above embodiment, the application provides a positioning device based on one-time printing calibration technology.
