Description

Technical Field

[0001] The utility model relates to the technical field of dental scanning, in particular to a large-span implant scanning auxiliary rod. Background Art

[0002] In the process of modern oral implant and restoration, digital scanning technology plays an important role, mainly relying on high-precision three-dimensional images to ensure the precise matching of implants and patients' teeth. The scanning rod is a commonly used tool in this process, used to stabilize the scanning device and guide intraoral scanning. At the same time, in order to improve the scanning accuracy, an auxiliary rod is often equipped as an additional positioning and identification point.

[0003] However, in the prior art, although the auxiliary rod provides key identification points, it is not the focus structure in the registration process itself, but only used as a positioning and reference tool. Therefore, during the three-dimensional registration and reconstruction stage, the existing auxiliary rods usually need to be removed. If these auxiliary rods are not deleted in the post-processing, it may distort the reconstructed model to prevent it from distorting the reconstructed model and affecting the true reproduction of the patient's intraoral structure.

[0004] Most current auxiliary rods are simple linear or circular structures. Although they help improve scanning accuracy, they will interfere with the normal operation of the registration algorithm. For example, these simple structures are confused with the real intraoral structure, making it difficult for the registration algorithm to accurately distinguish and process. Therefore, there is an urgent need to develop an auxiliary rod that can not only provide necessary identification points but also be easily recognized as a non-target structure by the algorithm during the registration process, thereby simplifying the data processing flow and improving the registration accuracy. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages existing in the prior art, and provide a large-span implant scanning auxiliary rod, which overcomes the limitations of traditional auxiliary rods in uneven distribution of identification points, low shape recognition efficiency, high data processing complexity, and operation complexity. The purpose of the utility model can be achieved by the following technical solutions:

[0006] The utility model provides a large-span implant scanning auxiliary rod, including:

[0007] A rod body, the main body of which is a cylindrical structure, provided with a geometric body or several single geometric bodies. The geometric body is used as an identification body to enhance the identification feature. Each geometric body is connected to the cylindrical rod structure through a concave transition structure to ensure the continuity of the shape recognition process; wherein, the geometric body is a cylinder or a regular polyhedron;

[0008] A connection structure for fixing the rod body to the connection port of the scanning rod.

[0009] Furthermore, the outer diameter of the geometric body is greater than the diameter of the cylindrical structure, which is used to highlight the identification body and the surface of the rod body.

[0010] Furthermore, the lateral section of the identification body is circular, triangular or quadrilateral, and the section width is 4 mm.

[0011] Furthermore, each geometric body on the rod body is arranged at a non-fixed interval, which is used to ensure that the identification points are unevenly distributed along the rod body.

[0012] Furthermore, the transition structure of the depression includes a cone, an inclined plane or a curved surface, which is used to optimize the shape transition from the cylindrical structure to the geometric body and reduce data interference during the scanning process.

[0013] Furthermore, the connecting structure is coaxial with the rod body, and the connecting structure includes threads for connecting with the connecting port of the scanning rod.

[0014] Furthermore, the length of the rod body is 6 mm to 15 mm, and the diameter of the cylindrical structure is 2 to 3 mm.

[0015] Furthermore, the materials of the rod body and the connecting structure are titanium metal, and the surface is treated with frosting.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] The present utility model provides a large-span implant scanning auxiliary rod with multiple lengths and multiple distinct geometric identification points. These identification points are composed of geometric bodies with non-uniform spacing, enhancing the accuracy of the scanned data. The geometric bodies are connected by a depression transition structure, which not only optimizes the reflection and refraction during the optical scanning process but also ensures the continuity of shape recognition, effectively reducing the complexity during the data processing stage. In addition, the structure of this auxiliary rod allows for more precise three-dimensional data reconstruction, improving the accuracy of implant positioning and restoration in intraoral scanning, thereby enhancing the quality of the final restoration and the user experience. Specifically, the more precise three-dimensional data reconstruction here specifically refers to assisting in the data reconstruction of the scanning rod.

[0018] By introducing connection structures of different shapes, such as a combined design of multiple shapes, the adaptability of the auxiliary rod is further enhanced, enabling it to more flexibly meet different scanning and registration requirements, such as personalized selection according to the distance between two adjacent composite abutments in the oral cavity. According to the distribution of implants in the user's oral cavity, an appropriate length of the auxiliary rod is selected and connected to the scanning rod, improving the accuracy and clinical operability of edentulous implant scanning and simplifying the clinical operation. The corresponding multiple-shaped identification points on the auxiliary rod facilitate the identification and image fusion registration of the intraoral scanner, thus ensuring the integrity and accuracy of the data during the scanning process.

[0019] The surface of the auxiliary rod is made of titanium metal and undergoes a matte treatment, which improves its durability and service life. At the same time, it reduces unnecessary reflections during the optical scanning process, thereby improving the accuracy of image acquisition. Description of the Drawings

[0026] The following describes the detailed embodiments of the present utility model in conjunction with the accompanying drawings and embodiments.

[0027] Embodiment 1

[0028] In modern oral implant procedures, digital scanning technology has become a key means to ensure the precise positioning of implants and optimize the restoration effect. Existing technologies usually use auxiliary rods to provide additional identification points, thereby enhancing the accuracy and integrity of scanning data. These auxiliary rods are mostly simple linear or circular structures, serving as prominent markers to help optical scanning devices capture key feature points. However, there are some obvious problems with existing auxiliary rods in practical applications. Specifically as follows: (1) The distribution of identification points is uneven. Traditional auxiliary rods may not be set with evenly distributed identification points, resulting in uneven scanning data and affecting the accuracy of the overall scanning quality. (2) The shape recognition efficiency is low. In some cases, simple cylindrical and linear-structured auxiliary rods may not be sufficient to provide enough feature identification points, making it challenging to perform high-precision scanning in complex oral interfaces. (3) The data processing complexity is high. Traditional auxiliary rods may be misrecognized by the scanning system as part of the target structure, thus increasing the complexity in the data processing stage. (4) Existing auxiliary rods may require complex connection methods or are not convenient for quick replacement and adjustment.

[0029] Therefore, due to the limitations of existing technologies, the present utility model provides a large-span implant scanning auxiliary rod, comprising:

[0030] A rod body 3, with a main body being a cylindrical structure. Along the length of the rod body 3, a geometric body 2 is provided or several single (i.e., unified) geometric bodies 2 are arranged at equal distances. This geometric body 2 serves as an identification body to enhance the identification features, thereby improving the progress and reliability during the scanning process. Each geometric body 2 is connected to the cylindrical rod structure, i.e., the rod body 3, through a concave transition structure, which is used to ensure the continuity of the shape recognition process and the optimization of the optical scanning process; wherein, the geometric body is a cylinder or a regular polyhedron.

[0031] A connection structure 1, which is used to fix the rod body 3 to the connection port of the scanning rod.

[0032] Wherein, the outer diameter of the geometric body 2 is larger than the diameter of the cylindrical structure, protruding from the surface of the rod body 3 for easy identification by the scanning device. The lateral cross-section of the identification body is circular, triangular, or quadrilateral, and the width of each cross-section is set to 4 mm.

[0033] It should be specifically noted that the lateral cross-section can be various shapes, such as circular, triangular, quadrilateral, pentagonal, or hexagonal. The specific shape is determined according to the design requirements of the auxiliary rod and the requirements of the scanning recognition technology.

[0034] In this embodiment, the cylindrical recognition body provides the recognition of the curved edge. Compared with the curved shape, the polygonal structure is easy to maintain the shape consistency and stability during the manufacturing process, which is crucial for ensuring the reliability of the scanning auxiliary rod in production and actual use. Triangles and quadrilaterals have unique angles and edges, and these features can serve as strong visual cues in image processing to help the scanning software more accurately locate and identify these markers. Moreover, compared with circular or other curved shapes, the straight lines and angles of triangles and quadrilaterals can be processed and registered by the algorithm more quickly. Finally, due to the large difference in shape between triangles and quadrilaterals and the shapes of natural teeth and other intraoral structures, they are less likely to be confused with the background or non-target structures, thus reducing the possibility of misidentification.

[0035] Furthermore, each geometric body 2 on the rod body 3 is arranged at a fixed interval, and a plurality of regular polygon recognition bodies are arranged equidistantly along the length of the rod body 3 to ensure the uniform distribution of the recognition points, thereby improving the consistency and reliability of the scanning.

[0036] Furthermore, the transition structure of the recess includes a cone, an inclined plane or a curved surface, which is used to optimize the shape transition from the cylindrical structure to the geometric body 2, reduce the data interference during the scanning process, and optimize the shape transition from the cylindrical structure to the geometric body 2.

[0037] Furthermore, the connecting structure 1 is coaxial with the rod body 3, and the connecting structure 1 includes a thread for realizing the precise combination with the connection port of the scanning rod.

[0038] Furthermore, the length of the rod body 3 is 6 mm to 15 mm, and the diameter of the cylindrical structure is 2 to 3 mm. The materials of the rod body 3 and the connecting structure 1 are titanium metal, and the surface is treated with frosting.

[0039] Therefore, the large-span scanning auxiliary rod of this embodiment can cover a wide scanning area, and is particularly suitable for the three-dimensional reconstruction requirements of the full dentition or complex oral structures. Through one scanning process, the device can capture more details in the oral cavity, significantly improving the integrity of the data and the accuracy of the reconstruction. This scanning rod is equipped with cylindrical and various polygon recognition bodies, allowing flexible selection and use according to different scanning stages and specific requirements, so as to optimize the overall effect of the scanning. This design not only reduces the workload of post-data processing, but also reduces the human error caused by misidentification. Therefore, while ensuring the clarity and reliability of the scanning fiducial points, this auxiliary rod greatly supports the application of high-precision scanning technology, improving the reliability and efficiency of the scanning process, especially when facing large-scale complex oral structures.

[0040] Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and its equivalent technologies, the utility model is also intended to include these modifications and variations.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
