Description

Technical Field

[0001] This application belongs to the field of oral restoration technology, specifically relating to a high-precision scanning rod structure for edentulous jaws. Background Technology

[0002] In current technology, the traditional method for taking impressions of edentulous patients involves using a composite transfer rod and a silicone rubber tray for transfer. This method connects the transfer rod to the composite abutment, and the intraoral environment is replicated onto the model using the silicone rubber tray before the restoration is fabricated. However, this traditional method has many drawbacks. The transfer rod is often too long, making it impossible to install properly if the patient's posterior teeth have limited opening during the transfer process. Furthermore, to ensure transfer accuracy, all transfer rods must be rigidly connected with wires, and a personalized tray must be fabricated for transfer. The entire process is relatively cumbersome, involves a lot of manual operation, and accumulates significant errors, severely affecting the final restorative outcome.

[0003] With the development of oral medicine, digital scanning poles have emerged. Installed on top of the implant, these poles determine the relative spatial relationship between the implant and adjacent tissues within the oral cavity, making them a crucial component in the digital implant restoration process. In clinical applications, the scanning pole is fixed to the implant, and an intraoral scanner can simultaneously acquire three-dimensional data of the pole, soft tissue, and adjacent teeth, thereby determining the implant's three-dimensional spatial position within the oral cavity. However, implant restorations in edentulous patients typically involve multiple implants, and these implants are often dispersed within the alveolar bone. This results in greater distances between adjacent scanning poles and fewer scanning feature points during digital scanning, increasing the difficulty of digital implant scanning. Furthermore, issues such as data layering, distortion, and poor accuracy can easily arise, ultimately affecting the precision of digital implant scanning.

[0004] Therefore, it is particularly urgent to design a high-precision scanning bar structure suitable for scanning multiple implants in edentulous jaws. Utility Model Content

[0005] This application aims to address the technical problem in the prior art where, during dental implant restoration for edentulous patients, multiple implants are typically placed. When these implants are dispersed within the alveolar bone, the distance between adjacent scanning rods is large, resulting in fewer scanning feature points, making it difficult for the scanning head to scan. This leads to issues such as data layering, distortion, and poor accuracy, resulting in low precision in digital implant scanning. To address this, a high-precision scanning rod structure for edentulous patients is proposed.

[0006] This application adopts the following solution: a high-precision scanning bar structure for edentulous patients, including an implant that fits into the alveolar bone and jaw of an edentulous patient, a plurality of scanning components spaced apart on the implant, a marking component on the scanning component, and a connecting component between the marking component and the scanning component. The connecting component includes a connecting ear on the marking component and a connecting groove on the connecting ear. The scanning component extends into the connecting groove to make the marking component detachably mounted on the scanning component.

[0007] In some feasible embodiments, the scanning assembly includes a connecting rod and a scanning head disposed on the connecting rod, the connecting rod being adaptable to extend into the connecting groove so that the marking component is detachably disposed on the scanning assembly.

[0008] In some feasible embodiments, the connecting assembly further includes a separator disposed on the connecting rod, the separator dividing the connecting rod into an upper connecting portion and a lower connecting portion, and the marking assembly being rotatable about the connecting rod when the connecting rod is fitted into the connecting groove.

[0009] In some feasible embodiments, the marking component includes a first marking plate, first marking grooves respectively disposed on both sides of the first marking plate, and a first marking portion protruding from the top of the first marking plate, and the connecting ear is disposed on one end of the first marking plate.

[0010] In some feasible embodiments, the first marking part is provided with multiple spaced portions along the length direction of the first marking plate, the first marking groove is provided with multiple spaced portions along the length direction of the first marking plate, and the cross-sectional shape of the first marking part is any one of star, hexagon, pentagon, and quadrilateral.

[0011] In some feasible embodiments, the marking assembly further includes a second marking plate, second marking grooves respectively disposed on both sides of the second marking plate, and a circular groove recessed on the top of the second marking plate. The circular grooves are provided in a staggered manner along the length direction of the second marking plate, and the connecting ear is disposed on one end of the second marking plate.

[0012] In some feasible embodiments, the number of the circular grooves is defined as N, where N satisfies the following relationship: 2≤N≤5.

[0013] In some feasible embodiments, the marking assembly further includes a third marking plate and third marking grooves disposed on both sides of the third marking plate. The cross-sectional area of ​​the third marking plate gradually increases and then gradually decreases along its length direction. The cross-sectional area of ​​the third marking plate near the connecting rod is smaller than the cross-sectional area away from the connecting rod.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] This application provides a high-precision scanning bar structure for edentulous patients, comprising an implant that conforms to the alveolar bone and jaw of an edentulous patient, multiple scanning components spaced apart on the implant, a marking component on the scanning components, and a connecting component between the marking component and the scanning components. The connecting component includes a connecting ear on the marking component and a connecting groove on the connecting ear. The scanning component extends into the connecting groove to allow the marking component to be detachably mounted on the scanning component. When implants are distributed widely, this application increases the number of scanning feature points through the multiple spaced scanning components and marking components, facilitating accurate scanning by the scanning head and effectively avoiding problems such as data layering, distortion, and poor accuracy. This significantly improves the accuracy of digital implant scanning, thereby improving the effect and quality of dental implant restoration for edentulous patients. Furthermore, the marking component is detachable, facilitating replacement and adjustment, and has the advantages of flexible use, convenient operation, and ease of promotion and implementation.

[0024] Combination Figure 1-8The following description further illustrates the technical solution proposed in this application. This application provides a high-precision scanning bar structure for edentulous patients, including an implant 1 that conforms to the alveolar bone and jaw of an edentulous patient, multiple scanning components 2 spaced apart on the implant 1, marking components 3 on the scanning components 2, and a connecting component 4 between the marking components 3 and the scanning components 2. The connecting component 4 includes a connecting ear 40 on the marking components 3 and a connecting groove 41 on the connecting ear 40. The scanning components 2 extend into the connecting groove 41, allowing the marking components 3 to be detachably mounted on the scanning components 2.

[0025] This application provides a high-precision scanning bar structure for edentulous patients, comprising an implant that conforms to the alveolar bone and jaw of an edentulous patient, multiple scanning components spaced apart on the implant, marking components on the scanning components, and a connecting component between the marking components and the scanning components. The connecting component includes a connecting ear on the marking component and a connecting groove on the connecting ear. The scanning components extend into the connecting grooves to allow the marking components to be detachably mounted on the scanning components. When implants are distributed widely, this application increases the number of scanning feature points through the multiple spaced scanning components and marking components, facilitating accurate scanning by the scanning head and effectively avoiding problems such as data layering, distortion, and poor accuracy. This improves the accuracy of digital implant scanning, thereby enhancing the effect and quality of dental implant restoration for edentulous patients. Furthermore, the marking components are detachable, facilitating replacement and adjustment, and have the advantages of flexible use, convenient operation, and ease of promotion and implementation.

[0026] In this embodiment, the scanning component 2 includes a connecting rod 20 and a scanning head 21 disposed on the connecting rod 20. The connecting rod 20 can be matched and extended into the connecting groove 41 so that the marking component 3 can be detachably disposed on the scanning component 2.

[0027] In practice, the implants are first installed on the jawbone of the edentulous patient, ensuring a close fit to the palate. The number and placement of the implants are determined based on the patient's specific oral condition and the required scanning accuracy.

[0028] In actual implementation, the connecting ear on the sign component has a connecting slot. Align the connecting rod of the scanning component with the connecting slot and insert it into it, so that the sign component can be detachably connected to the scanning component. This makes it easier to disassemble and replace the sign component when it needs to be replaced or when the scanning component malfunctions.

[0029] In actual implementation, it also includes a threaded hole on the connecting rod and a stud on the scanning head that corresponds to the threaded hole. The scanning head and the connecting rod are detachably fixed by matching the stud with the threaded hole.

[0030] In this embodiment, the connecting component 4 further includes a separator 42 disposed on the connecting rod 20. The separator 42 divides the connecting rod 20 into an upper connecting part 200 and a lower connecting part 201. When the connecting rod 20 is inserted into the connecting groove 41, the marking component 3 can rotate relative to the connecting rod 20.

[0031] In actual implementation, after the separator divides the connecting rod into an upper connecting part and a lower connecting part, two marking components can be set on the connecting rod at the same time. Adjacent scanning components can be connected through the marking components to form concentrated and continuous scanning feature points inside the patient's oral cavity, reducing the difficulty of digital implant scanning and avoiding issues such as layering, deformation, and poor accuracy of scanning data, thereby improving the accuracy of digital implant scanning.

[0032] In this embodiment, the marking component 3 includes a first marking plate 50, first marking grooves 51 respectively disposed on both sides of the first marking plate 50, and a first marking part 52 protruding from the top of the first marking plate 50. The connecting ear 40 is disposed on one end of the first marking plate 50.

[0033] In this embodiment, the first marking part 52 is provided with multiple intervals along the length direction of the first marking plate 50, and the first marking groove 51 is provided with multiple intervals along the length direction of the first marking plate 50. The cross-sectional shape of the first marking part 52 is any one of star, hexagon, pentagon and quadrilateral.

[0034] In practice, the first marking groove and the first marking part can increase the number of scanning feature points in the patient's oral cavity, reduce the difficulty of digital implant scanning, and avoid the occurrence of scanning data layering, deformation, and poor accuracy, thereby improving the accuracy of digital implant scanning.

[0035] In actual implementation, the number of first marker slots and the number of first marker parts can be determined based on the degree of dispersion of the implants in the patient's oral cavity.

[0036] In this embodiment, the marking component 3 further includes a second marking plate 60, second marking grooves 61 respectively provided on both sides of the second marking plate 60, and a circular groove 62 recessed on the top of the second marking plate 60. The circular grooves 62 are provided in multiple staggered intervals along the length direction of the second marking plate 60, and the connecting ear 40 is provided on one end of the second marking plate 60.

[0037] In this embodiment, the number of the circular grooves 62 is defined as N, and N satisfies the following relationship: 2≤N≤5.

[0038] For example, N can take the values ​​2, 3, 4, or 5.

[0039] In practice, by setting up multiple circular grooves and arranging them in an alternating pattern, the number of scanning feature points inside the patient's oral cavity is increased, significantly reducing the difficulty of scanning.

[0040] In this embodiment, the marking component 3 further includes a third marking plate 70 and third marking grooves 71 disposed on both sides of the third marking plate 70. The cross-sectional area of ​​the third marking plate 70 gradually increases and then gradually decreases along its length direction. The cross-sectional area of ​​the third marking plate 70 at the end near the connecting rod 20 is smaller than the cross-sectional area at the end away from the connecting rod 20.

[0041] In practice, by designing the cross-sectional area of ​​the third marker plate, the number of scanning feature points inside the patient's oral cavity is further increased, significantly reducing the difficulty of scanning.

[0042] This application provides a high-precision scanning bar structure for edentulous patients, comprising an implant that conforms to the alveolar bone and jaw of an edentulous patient, multiple scanning components spaced apart on the implant, marking components on the scanning components, and a connecting component between the marking components and the scanning components. The connecting component includes a connecting ear on the marking component and a connecting groove on the connecting ear. The scanning components extend into the connecting grooves to allow the marking components to be detachably mounted on the scanning components. When implants are distributed widely, this application increases the number of scanning feature points through the multiple spaced scanning components and marking components, facilitating accurate scanning by the scanning head and effectively avoiding problems such as data layering, distortion, and poor accuracy. This improves the accuracy of digital implant scanning, thereby enhancing the effect and quality of dental implant restoration for edentulous patients. Furthermore, the marking components are detachable, facilitating replacement and adjustment, and have the advantages of flexible use, convenient operation, and ease of promotion and implementation.
