Description

Technical Field

[0001] This application relates to the field of implant carrier technology, and in particular to an implant carrier that is easy to scan. Background Technology

[0002] Implant carriers are essential tools in the field of prosthodontics, widely used in dental implant surgery. With the development of modern dental technology, implant carriers not only need to meet basic installation functions but also require higher precision and versatility to adapt to the trend of digital dental restoration. Traditional implant carriers primarily achieve fixation to the implant through mechanical connections. This design, to a certain extent, meets basic clinical needs, but with increasing demands for implant placement accuracy and the application of digital restorative technologies, the functional limitations of traditional tools are becoming increasingly apparent.

[0003] In existing technologies, to solve the problems of implant installation and measurement, screw-connected carriers or simple mechanical mating structures are usually used. The former uses threaded connections to fix the implant, which can provide high connection strength, but requires additional screw parts, and the assembly process is complicated and requires strict control of torque; the latter uses simple geometric mating to achieve connection, but often cannot meet the needs of accurate measurement.

[0004] However, existing implant carriers generally lack an integrated design, failing to simultaneously meet the needs of scanning, measurement, and convenient installation. Particularly during transportation and installation, traditional carriers are prone to detachment due to unstable connections, leading to implant misalignment and affecting surgical outcomes. Furthermore, the lack of monitoring of gingival thickness and precise control over implant placement direction in traditional designs limits their application value in digital restorations. Therefore, designing an implant carrier capable of accurate measurement and good scanning compatibility has become a pressing technical challenge. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides an implant carrier that is easy to scan.

[0006] The implant carrier that is easy to scan provided in this application adopts the following technical solution:

[0007] An easily scannable implant carrier, comprising:

[0008] The post includes a measuring platform for use with an oral scanner to measure the gap between adjacent teeth;

[0009] A bar portion, connected to the post portion, the bar portion including an observation element for observing the thickness of the gingiva; and

[0010] A connecting part is connected to the end of the observation piece away from the post, and the connecting part is connected to the implant.

[0011] By employing the above-mentioned technical solutions, the implant carrier can measure the gaps between adjacent teeth, thus providing accurate data support for implant placement. Simultaneously, the design of the observation piece allows for direct observation of gingival thickness, aiding in the assessment of implant adaptability after placement. The connector design ensures a stable connection between the carrier and the implant, preventing detachment during transportation and installation, and improving ease of use and reliability.

[0012] Preferably, the pile also includes a locking member, which is integrally connected to the measuring platform and is located on the side of the measuring platform away from the pole.

[0013] By adopting the above technical solution, the locking component is integrally connected to the measuring platform and located on the side of the measuring platform away from the pole. This provides additional fixation during implant installation, ensuring that the carrier will not easily detach from the implant during transportation and operation, thereby improving the overall structural stability. This design requires no additional accessories, simplifies the assembly process, and enhances the reliability of the connection between the carrier and the implant.

[0014] Preferably, it also includes a torque break point structure, which is located at the connection shaft between the measuring platform and the rod, and automatically breaks when the torque exceeds a threshold.

[0015] By adopting the above technical solution, when the torque exceeds the threshold, the torque break structure can automatically break, thereby effectively preventing damage to the implant carrier or other connecting parts due to excessive force, ensuring operational safety and protecting the stability of the overall structure.

[0016] Preferably, the observation element includes a plurality of observation units formed on the surface of the observation element, each observation unit being a plurality of hemispherical grooves spaced apart along the length direction of the observation element, the observation units being linear in shape, and the observation units being arranged circumferentially with the central axis of the observation element as the axis.

[0017] By adopting the above technical solution, the observation piece has a cylindrical rod structure, and its surface is provided with multiple hemispherical grooves spaced apart along its length. These grooves form a linear observation unit, arranged circumferentially around the rod as its central axis. This design allows the observation piece to accurately reflect changes in gingival thickness, improving the accuracy and reliability of the measurement. Simultaneously, the circumferentially arranged observation unit ensures effective observation of the gingival condition from different angles, enhancing the flexibility and convenience of use.

[0018] Preferably, the connecting part includes a connecting member and a self-locking member. The connecting member is connected to the observation member and the self-locking member respectively. The connecting member extends into the implant and cooperates with the interior of the implant to restrict the circumferential movement of the implant. The self-locking member extends into the implant and cooperates with the interior of the implant to restrict the displacement of the implant along the length direction.

[0019] By adopting the above technical solution, the connecting component and the self-locking component of the connector work together. The connecting component extends into the implant to restrict the circumferential movement of the implant, thereby preventing the carrier from rotating during use. The self-locking component also extends into the implant to further restrict the displacement of the implant along its length, ensuring that the carrier will not easily fall off during transportation and installation. Together, they achieve a stable connection between the implant and the carrier, improving the convenience of installation and disassembly, while avoiding assembly problems caused by improper torque control.

[0020] Preferably, the surface of the connector is provided with a plurality of evenly spaced circular protrusions, and an arc-shaped groove is formed between adjacent circular protrusions. The inner wall of the implant is provided with an arc-shaped protrusion that mates with the arc-shaped groove.

[0021] By adopting the above technical solution, the combination of circular protrusions and arc-shaped grooves effectively restricts the circumferential movement of the implant, ensuring a stable connection between the carrier and the implant. Specifically, the circular protrusions on the connector cooperate with the arc-shaped protrusions on the inner wall of the implant to prevent the carrier from rotating inside the implant, thereby improving installation accuracy and stability. The evenly spaced circular protrusions ensure more uniform stress distribution, avoiding localized stress concentration and extending service life. This structure requires no additional fixing accessories, simplifying the assembly process and improving ease of operation.

[0022] Preferably, the self-locking component comprises multiple elastic locking blocks, with at least two elastic locking blocks. The elastic locking blocks are symmetrically arranged around the central axis of the rod portion, and the elastic locking blocks engage with the threaded inner cavity of the implant through elastic deformation.

[0023] By adopting the above technical solution, the design of the elastic locking block enables the connection part to reliably engage with the threaded cavity of the implant. Since there are at least two elastic locking blocks arranged symmetrically at the center, this structure provides a stable fixation effect during implant transportation and installation, preventing dislodgement. Simultaneously, the elastic locking block engages with the threaded cavity of the implant through elastic deformation, eliminating the need for additional screws, simplifying the assembly process, reducing production costs, and avoiding the problem of precise torque control required in traditional torque connection methods, thus improving assembly efficiency and reliability.

[0024] Preferably, the rod portion further includes a limiting block disposed between the observation member and the connecting member, wherein the outer diameter of the limiting block is larger than the inner diameter of the implant.

[0025] By adopting the above technical solution, the limiting block is positioned between the observation piece and the connecting piece, and the outer diameter of the limiting block is larger than the inner diameter of the implant. This effectively prevents the connecting part from being over-inserted into the implant, thereby avoiding damage to the internal structure of the implant or affecting the fitting accuracy between the implant and the carrier. At the same time, the limiting block plays a positioning role, ensuring that the end face of the observation piece coincides with the end face of the implant opening, guaranteeing good stability and reliability of the device during use.

[0026] Preferably, the number of the circular protrusions corresponds to the number of the observation units.

[0027] By adopting the above technical solution, the circular protrusions of the implant carrier are correspondingly positioned with the observation units, ensuring that the position of each observation unit precisely matches the internal structure of the implant. This design ensures that the measurement data provided by the observation units is more accurate and reliable when observing gingival thickness. Simultaneously, the fit between the circular protrusions and the implant interior is more stable, improving the positioning accuracy and ease of operation during implant installation. Specifically, the number and position of the circular protrusions correspond to the observation units, enhancing the spatial correlation between the observation units and the internal structure of the implant, and improving measurement accuracy.

[0028] Preferably, when the connecting part is inserted into the implant, the end face of the observation piece near the implant coincides with the end face of the implant opening.

[0029] By adopting the above technical solution, when the connecting part is engaged with the implant, the end face of the observation piece near the implant coincides with the end face of the implant opening, which can ensure the accurate alignment of the implant after installation and avoid measurement errors caused by uneven end faces, thereby improving the stability and reliability of the overall device during use.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The post measurement platform can work with an oral scanner to accurately measure the gap between adjacent teeth, simplifying the measurement process and improving measurement accuracy;

[0032] 2. The observation piece on the bar has a special structural design that allows for direct observation of gingival thickness, reducing reliance on additional measuring tools and improving ease of operation;

[0033] 3. The flexible connection between the connector and the implant ensures stable installation of the implant and avoids time wastage caused by frequent tool changes, thus improving surgical efficiency. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0041] This application discloses an implant carrier that is easy to scan.

[0042] refer to Figure 1 and Figure 2 An easy-to-scan implant carrier includes a post 1, a rod 2, and a connecting part 3. The post 1 is connected to the rod 2 via a measuring platform 10, and the rod 2 is connected to the connecting part 3 via an observation piece 21. The post 1, rod 2, and connecting part 3 are coaxially arranged, and the connecting part 3 forms a stable connection with the implant 4, achieving the effects of convenient installation, accurate measurement, and good compatibility. Specifically, this is due to the reasonable design and optimized coordination of each part of the structure.

[0043] The post 1 includes a measuring platform 10 and a locking element 11. The measuring platform 10, in conjunction with an oral imaging instrument, measures the distance between adjacent teeth. The locking element 11 is rotated to implant and fix the implant 4. Specifically, the measuring platform 10 has a frustum-shaped structure and is available in different sizes to adapt to different working scenarios. The locking element 11 is integrally connected to the measuring platform 10 and uses a hexagonal nut. The outer surface of the measuring platform 10 is coated with a radiopaque coating, which can be either polymethyl methacrylate (PMMA) or zirconia ceramic coating. An ArcScan scanner, suitable for medical use, can be used in conjunction with the dental scanner to prepare for subsequent dental procedures.

[0044] refer to Figures 1-5 The rod 2 includes an observation element 21 and a limiting block 22. Specifically, the observation element 21 has a cylindrical rod structure with multiple observation units 211 on its surface. There are six observation units 211, each consisting of multiple hemispherical grooves 2111 spaced apart along the length of the observation element 21. Each observation unit 211 has three hemispherical grooves 2111 to facilitate the dentist's observation of gingival thickness and the implantation direction of the implant 4. Each observation unit 211 is linear and circumferentially arranged with the central axis of the observation element 21 as the reference to ensure uniformity and accuracy of observation. The limiting block 22 is located between the observation element 21 and the connecting part 31. Its outer diameter is larger than the inner diameter of the implant 4. When the connecting part 3 extends into the implant 4, the end face of the limiting block 22 away from the rod 2 coincides with the upper end face of the arc-shaped protrusion 41 near the limiting block 22, which prevents over-insertion. The shape of the limiting block 22 can be designed as cylindrical or conical, depending on the fitting requirements with the implant 4.

[0045] Specifically, the connecting part 3 includes a connecting member 31 and a self-locking member 32. The connecting member 31 has multiple evenly spaced circular protrusions 311 around its circumference, forming an arc-shaped groove 312 between adjacent circular protrusions 311. The inner wall of the implant 4 has arc-shaped protrusions 41 that mate with the arc-shaped grooves 312. The connecting member 31 extends into the implant 4, and the arc-shaped grooves 312 and arc-shaped protrusions 41 mate to restrict the circumferential movement of the implant 4, ensuring connection stability. The self-locking member 32 consists of multiple elastic locking blocks 321, with at least two elastic locking blocks 321 symmetrically arranged around the central axis of the rod 2. Through elastic deformation, they engage with the threaded inner cavity 42 of the implant 4, thereby restricting the displacement of the implant 4 along its length. The elastic locking blocks 321 can be made of stainless steel or titanium alloy, possessing a high elastic modulus (200-250 GPa) and a deformation controlled within 0.5-1.5 mm.

[0046] In addition, this device is equipped with a torque break point structure 5, located at the connection shaft between the measuring platform 10 and the rod 2. When the torque exceeds a set threshold (25-35 N / cm), the torque break point structure 5 will automatically break, preventing damage to the implant 4 and surrounding tissues due to excessive force. The torque break point structure 5 is a pre-designed brittle material layer, such as medical-grade polyetheretherketone (PEEK), which has high rigidity, low elastic modulus (PEEK: 3.5-4.0 GPa), and controllable fracture characteristics. It can precisely match the installation torque range of the implant 4. This design not only improves safety but also extends the service life of the equipment.

[0047] The implementation principle of an easy-to-scan implant carrier according to an embodiment of this application is as follows: In use, the connecting part 3 is inserted into the implant 4, the arc-shaped protrusion 41 and the arc-shaped groove 312 are engaged and locked in place, the self-locking part 32 is engaged with the threaded inner cavity 42, and then the implant 4 is connected to the device. The implant 4 is inserted into the installation position, the measuring platform 10 is used in conjunction with the oral scanner to measure the distance between adjacent teeth, the locking part 11 is rotated to drive the implant 4 to rotate and be implanted, when a certain safety threshold is reached, the torque break point structure 5 automatically breaks, the post 1 is removed, the direction of the observation unit is checked to determine the direction of the implant, and the relative position of the hemispherical groove 2111 and the surrounding gingiva is observed to confirm the thickness of the gingiva.

[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
