[0024] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.
[0025] Figure 4 FIG. 1 is a schematic structural diagram of a registration device according to an embodiment of the present application.
[0026] like Figure 4 As shown, the registration device 10 includes a tray 11 and a plurality of marking rods 13 .
[0027] The tray 11 is an arched sheet structure for the edentulous patient to bite in. When the tray 11 is placed between the upper and lower jaws of the edentulous patient and the edentulous patient bites the tray 11, the arch of the tray 11 matches the arch of the alveolar bone of the edentulous patient.
[0028] A plurality of marker rods 13 are provided on at least one surface of the tray 11 and are arranged at intervals along the extension direction D1 of the tray 11. The extension direction D1 of the tray 11 is the same as the direction of the arch curve of the alveolar bone of the edentulous patient. The plurality of marker rods 13 can be arranged at intervals along the extension direction D1 of the tray 11 on the same surface of the tray 11, such as the upper surface or the lower surface of the tray 11; the plurality of marker rods 13 can also be arranged at intervals along the extension direction D1 of the tray 11 on two surfaces of the tray 11, such as the upper surface or the lower surface of the tray 11. By arranging the plurality of marker rods 13 at intervals along the extension direction D1 of the tray 11, the plurality of marker rods 13 can be arranged in an arch shape on at least one surface of the tray 11, so that the arrangement shape of the plurality of marker rods 13 is adapted to the arch shape of the alveolar bone on the corresponding jaw side of the edentulous patient.
[0029] The multiple marking rods 13 are used to adhere paint, for example, paint can be adhered to the ends of the multiple marking rods 13. The multiple marking rods 13 are also used to transfer the paint adhered to their respective ends to the alveolar mucosa on the corresponding jaw side of the edentulous patient when the tray 11 is engaged, thereby forming multiple first marking points (not shown in the drawings) on the corresponding alveolar mucosa, and making the multiple first marking points correspond one-to-one with the ends of the multiple marking rods 13. The multiple first marking points and the ends of the multiple marking rods 13 can be clearly displayed in an image scan such as an X-ray or CT scan.
[0030] Exemplarily, when the plurality of marking rods 13 are arranged on the upper surface of the tray 11, the plurality of marking rods 13 can transfer the paint adhered to the respective end portions to the mucosa of the maxillary alveolar bone of the edentulous patient to form a plurality of first marking points on the mucosa of the maxillary alveolar bone of the edentulous patient, which are arranged along the direction of the arc curve of the maxillary alveolar bone at intervals. When the plurality of marking rods 13 are arranged on the lower surface of the tray 11, the plurality of marking rods 13 can transfer the paint adhered to the respective end portions to the mucosa of the mandibular alveolar bone of the edentulous patient to form a plurality of first marking points on the mucosa of the mandibular alveolar bone of the edentulous patient, which are arranged along the direction of the arc curve of the mandibular alveolar bone at intervals. In this way, the plurality of first marking points can be one-to-one corresponding to the end portions of the plurality of marking rods 13, and the setting of the marking points of the edentulous patient is realized, so as to provide a reference base for subsequent registration; wherein the end portions of the plurality of marking rods 13 can serve as a plurality of second marking points. For example, in subsequent registration, the one-to-one correspondence between the plurality of first marking points and the plurality of second marking points can be used to register the three-dimensional upper dental arch bone image of the edentulous patient with the three-dimensional registration device image and / or register the three-dimensional mandibular alveolar bone image of the patient with the three-dimensional registration device image, and register the three-dimensional registration device image with the three-dimensional facial image of the patient, so that the three-dimensional upper dental arch bone image and / or the three-dimensional mandibular alveolar bone image are superimposed with the three-dimensional facial image.
[0031] The above scheme, since the registration device 10 comprises the tray 11 in an arc-shaped sheet structure and the plurality of marking rods 13 arranged on at least one surface of the tray 11, and the plurality of marking rods 13 are arranged at intervals along the extension direction D1 of the tray 11, and the plurality of marking rods 13 are arranged for adhering paint, so that when the edentulous patient bites the tray 11, the plurality of marking rods 13 can transfer the paint adhered to the respective end portions to the mucosa of the corresponding jaw side alveolar bone of the edentulous patient to form a plurality of first marking points on the corresponding alveolar bone mucosa, and the plurality of first marking points are one-to-one corresponding to the end portions of the plurality of marking rods 13. In this way, the registration device 10 can set a plurality of first marking points for the edentulous patient, and use the end portions of the plurality of marking rods 13 as a plurality of second marking points, to realize a registration device 10 capable of setting marking points for the edentulous patient. In addition, it should be noted that the registration device 10 of the embodiment of the present application sets the marking points for the edentulous patient in a non-invasive manner, which is more helpful to reduce additional incisions.
[0032] In an embodiment, as Figure 4As shown, the plurality of marking rods 13 includes a plurality of first marking rods 131 and a plurality of second marking rods 132. The plurality of first marking rods 131 is vertically arranged on the upper surface of the tray 11, and is used to transfer the adhered paint to the mucosa of the maxillary alveolar bone of the edentulous patient, so as to form a plurality of first sub-marking points on the mucosa of the maxillary alveolar bone, and realize the setting of the marking points on the mucosa of the maxillary alveolar bone of the edentulous patient. The plurality of second marking rods 132 is vertically arranged on the lower surface of the tray 11, and is used to transfer the adhered paint to the mucosa of the mandibular alveolar bone of the edentulous patient, so as to form a plurality of second sub-marking points on the mucosa of the mandibular alveolar bone, and realize the setting of the marking points on the mucosa of the mandibular alveolar bone of the edentulous patient. The plurality of first sub-marking points and the plurality of second sub-marking points constitute the plurality of first marking points. Based on this, the plurality of first marking rods 131 can be used to set the plurality of first sub-marking points on the mucosa of the maxillary alveolar bone of the edentulous patient, and at the same time, the plurality of second marking rods 132 can be used to set the second sub-marking points on the mucosa of the mandibular alveolar bone of the edentulous patient, which is beneficial to improve the setting efficiency of the first marking points.
[0033] In an embodiment, as shown in Figure 4 The plurality of first marking rods 131 is arranged adjacent to the outer side of the upper surface of the tray 11, and the plurality of second marking rods 132 is arranged adjacent to the inner side of the lower surface of the tray 11.
[0034] In actual application, when the edentulous patient is in a resting state, the maxillary alveolar bone and the mandibular alveolar bone are naturally occluded, the maxillary alveolar bone is closer to the labial side of the edentulous patient, and the mandibular alveolar bone is farther away from the labial side of the edentulous patient. By arranging the plurality of first marking rods 131 adjacent to the outer side of the upper surface of the tray 11, and arranging the plurality of second marking rods 132 adjacent to the inner side of the lower surface of the tray 11, the positions of the plurality of first marking rods 131 can be adapted to the positions of the maxillary alveolar bone when the maxillary alveolar bone is in a natural occlusion state, and the positions of the plurality of second marking rods 132 can be adapted to the positions of the mandibular alveolar bone when the mandibular alveolar bone is in a natural occlusion state, which is helpful to accurately transfer the paint to the mucosa of the maxillary alveolar bone by the plurality of first marking rods 131, and to accurately transfer the paint to the mucosa of the mandibular alveolar bone by the plurality of second marking rods 132. In this way, it is beneficial to improve the accuracy of setting the first marking points.
[0035] In an embodiment, as shown in Figure 4 The plurality of first marking rods 131 and the plurality of second marking rods 132 are both cylindrical and uniformly arranged along the extension direction of the tray 11, the diameter range of the plurality of first marking rods 131 and the plurality of second marking rods 132 is 1nm-3nm (including the end point value), and the number range of the plurality of first marking rods 131 and the plurality of second marking rods 132 is 6-12 (including the end point value).
[0036] Exemplarily, the plurality of first marking points comprises a plurality of first sub-marking points and a plurality of second sub-marking points. When the plurality of first marking rods 131 is used to transfer the paint to the upper alveolar mucosa of the edentulous patient, and the plurality of second marking rods 132 is used to transfer the paint to the lower alveolar mucosa of the edentulous patient, the plurality of first sub-marking points formed on the upper alveolar mucosa and the plurality of second sub-marking points formed on the lower alveolar mucosa are all round dots. During the process of transferring the paint, under the action of the occlusal force, the area of the first sub-marking point formed by the paint on the upper alveolar mucosa is greater than the projection area of the paint on the end of the first marking rod 131, and the area of the second sub-marking point formed by the paint on the lower alveolar mucosa is greater than the projection area of the paint on the end of the second marking rod 132. By setting the diameter of the plurality of first marking rods 131 and the plurality of second marking rods 132 to be between 1 nm and 3 nm, and setting the number of the plurality of first marking rods 131 and the plurality of second marking rods 132 to be between 6 and 12, the area and density of the plurality of first marking points and the plurality of second marking points can be within a suitable range, thereby avoiding overlapping between adjacent two first sub-marking points and avoiding overlapping between adjacent two second sub-marking points, and ensuring that the plurality of first sub-marking points and the plurality of second sub-marking points are clearly visible, which is conducive to improving the reliability of the marking point setting.
[0037] In an embodiment, as shown in FIG. 1, the height of the plurality of first marking rods 131 and the plurality of second marking rods 132 gradually decreases along the extension direction D2 from the middle part to the end part of the tray 11. Figure 4
[0038] In actual application, the height of the tooth gradually decreases along the direction from the anterior region to the posterior region. By setting the height of the plurality of first marking rods 131 and the plurality of second marking rods 132 to gradually decrease along the extension direction D2 from the middle part to the end part of the tray 11, the height distribution of the plurality of first marking rods 131 and the plurality of second marking rods 132 can be adapted to the distribution of the height of the tooth, which can improve the adaptability between the plurality of first marking rods 131 and the upper alveolar mucosa, and improve the adaptability between the plurality of second marking rods 132 and the lower alveolar mucosa, which is conducive to the plurality of first marking rods 131 setting the plurality of first sub-marking points with uniform shapes on the upper alveolar mucosa, and conducive to the plurality of second marking rods 132 setting the plurality of second sub-marking points with uniform shapes on the lower alveolar mucosa, thereby improving the uniformity of the marking point setting.
[0039] It should be noted that, in order to make the drawings simple, Figure 4 In an embodiment, as shown in FIG. 1, the height of the plurality of first marking rods 131 and the plurality of second marking rods 132 gradually decreases along the extension direction D2 from the middle part to the end part of the tray 11. Figure 4 As shown, the outer side edge of the tray 11 is provided with a first surrounding plate 14, and the inner side edge of the tray 11 is provided with a second surrounding plate 15, the first surrounding plate 14 is opposite to the second surrounding plate 15 and extends along the extension direction D1 of the tray 11. In this way, when the edentulous patient bites the tray 11, the maxillary alveolar bone and the mandibular alveolar bone can be limited between the first surrounding plate 14 and the second surrounding plate 15, so that the maxillary alveolar bone mucosa is opposite to the plurality of first marking rods 131 and the mandibular alveolar bone mucosa is opposite to the plurality of second marking rods 132, which is beneficial to improve the convenience of setting the marking points.
[0040] In an embodiment, as shown in Figure 4 The height of the first surrounding plate 14 and the second surrounding plate 15 gradually decreases along the extension direction D2 of the middle part to the end part of the tray 11. In this way, the height of the first surrounding plate 14 can be matched with the thickness of the maxillary alveolar bone, and the height of the second surrounding plate 15 can be matched with the thickness of the mandibular alveolar bone, which is beneficial to improve the comfort of use.
[0041] In an alternative embodiment, as shown in Figure 4 The height of the plurality of marking rods 13 is lower than the height of the first surrounding plate 14 and the second surrounding plate 15 at the corresponding position along the vertical direction D3 of the extension direction D1 of the tray 11. For example, the height of the marking rod 13 located in the middle part of the tray 11 is 5mm, the height of the marking rod 13 located in the end part of the tray 11 is 2mm, the height of the first surrounding plate 14 located in the middle part of the tray 11 and the second surrounding plate 15 located in the middle part of the tray 11 is 1cm, and the height of the first surrounding plate 14 located in the end part of the tray 11 and the second surrounding plate 15 located in the end part of the tray 11 is 0.5cm. Based on this, when the tray 11 is placed in the oral cavity of the edentulous patient and is bitten, it can prevent the tray 11 from being normally bitten due to the height of the marking rod 13 being too high, and affect the limiting effect of the first surrounding plate 14 and the second surrounding plate 15.
[0042] In another alternative embodiment, the height of the plurality of marking rods 13 is higher than the height of the first surrounding plate 14 and the second surrounding plate 15 at the corresponding position along the vertical direction D3 of the extension direction D1 of the tray 11. In this way, it is helpful for the doctor to grind the height of the plurality of marking rods 13 according to the biting condition of the edentulous patient before using the registration device 10, so that the height of the plurality of marking rods 13 is matched with the biting condition of the patient. In an embodiment, as shown in Figure 4As shown, the outer side of the middle part of the tray 11 is provided with a mounting plate 16, and the side of the mounting plate 16 away from the tray 11 is provided with a plug 161 perpendicular to the mounting plate 16. The registration device 10 further comprises a registration plate 12, and the inner side of the registration plate 12 is provided with a plug-in seat 17, and the middle part of the plug-in seat 17 defines a plug-in port 171, and the plug 161 is detachably plugged with the plug-in port 171. In this way, the registration plate 12 and the tray 11 can be detachably assembled, and the tray 11 and the registration plate 12 can be flexibly used.
[0043] In an embodiment, as shown in Figure 4 and Figure 4 As shown, the registration plate 12 is provided with a plurality of first registration pits 121a, two second registration pits 121b and a third registration pit 121c.
[0044] The plurality of first registration pits 121a are recessed from the inner side of the registration plate 12 to the outer side and are spaced apart and surrounded by a triangle at the periphery of the plug-in seat 17. Since the triangle has stability, by surrounding the plurality of first registration pits 121a by a triangle, the accuracy of subsequent registration using the plurality of first registration pits 121a is improved. For example, as shown in Figure 5 Figure 2A In the related art, by setting 3 first mark points 31 on the residual dentition 21 of the patient, and setting corresponding 3 second mark points 32 on the three-dimensional dental impression model 22, the 3 first mark points 31 and the 3 second mark points 32 are surrounded by a triangle, and then when the three-dimensional dentition image 41 and the three-dimensional registration device image 42 are registered, the 3 first mark points 31 and the 3 second mark points 32 can be registered one by one, avoiding the shift between the three-dimensional dentition image and the three-dimensional registration device image, and improving the accuracy of registration.
[0045] The two second registration pits 121b are recessed from the outer side of the registration plate 12 to the inner side and are respectively located at the two sides of the plug-in seat 17, and the third registration pit 121c is recessed from the inner side of the registration plate 12 to the outer side and is located at the middle part of the plug-in seat 17 and perpendicular to the plug-in seat 17. By setting the two second registration pits 121b respectively at the two sides of the plug-in seat 17 and setting the third registration pit 121c at the middle part of the plug-in seat 17 and perpendicular to the plug-in seat 17, the ends of the two second registration pits 121b and the third registration pit 121c are also surrounded by a triangle, which is beneficial to improve the accuracy of subsequent registration using the two second registration pits 121b and the third registration pit 121c.
[0046] The shape of the first registration pit 121a can be triangular, the shape of the second registration pit 121b can be circular, and the shape of the third registration pit 121c can be a rounded rectangle. It should be noted that the shapes of the first registration pit 121a, the second registration pit 121b, and the third registration pit 121c can be selected and adjusted according to actual needs, and the embodiments of the present application do not limit this.
