[0002] With the development of digital dentistry, 3D printing technology is increasingly being used in the field of dental implantology. Doctors typically construct a 3D model based on CT scan data of the patient's jawbone and then use 3D printing technology to create an implant model for preoperative simulation, implant guide design, and precise planning of implant placement. In this process, the surrogate within the implant model simulates the actual state of the implant after placement and is an important component of the implant model.

[0003] In current common planting models, the substitute usually needs to be installed on the model base by threaded connection or snap-fit. During use, improper installation can easily lead to positional displacement, affecting the accuracy of the model. In addition, frequent disassembly and assembly can also cause the fit between the substitute and the model to loosen, reducing the reusability and stability of the model. Therefore, how to simplify the installation structure of the substitute and improve its fit stability and ease of operation with the model body has become an urgent problem to be solved in the current planting model design. Utility Model Content

[0009] Preferably, the buffer and shock-absorbing cavity is composed of multiple annular chambers spaced apart from each other, and the chambers are separated by thin-walled structures to form compressible deformation areas.

[0010] Preferably, the first magnetic attractor and the second magnetic attractor are pre-embedded structures.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This installation-free 3D-printed planting model eliminates traditional installation steps through its integrated embedded structure design, improving the positioning accuracy and overall stability of the substitute, simplifying operation, and enhancing the model's reusability and production efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a 3D-printed planting model with a no-installation substitute, including a model body 1 and a substitute 2. The model body 1 has a positioning cavity 3, and a first magnetic suction member 4 is embedded in the bottom of the positioning cavity 3. The bottom of the substitute 2 has a flange portion that is adapted to the structure of the upper end of the positioning cavity 3. The bottom of the flange portion of the substitute 2 has a second magnetic suction member 5 that matches the first magnetic suction member 4. The first magnetic suction member 4 and the second magnetic suction member 5 are fixed by attraction through opposite magnetic poles. The lower part of the substitute 2 also has a guide post 6. The positioning cavity 3 has a guide hole 7 that cooperates with the guide post 6. The substitute 2 also has a buffer and shock absorption cavity 8 inside. This structure provides installation space for the substitute 2 through the positioning cavity 3 on the model body 1. The first magnetic chuck 4 and the second magnetic chuck 5 utilize the attraction force between opposite magnetic poles to quickly fix the substitute 2 to the model body 1, eliminating the need for traditional threaded or snap-fit ​​connections. The cooperation between the guide post 6 and the guide hole 7 ensures precise alignment of the substitute 2 during insertion, avoiding assembly errors caused by misalignment. Simultaneously, the buffer and shock-absorbing cavity 8, distributed inside the substitute 2, absorbs stress through its own structural deformation when subjected to external pressure or impact during assembly / disassembly, reducing the impact of rigid collisions on the overall model structure. This model not only simplifies the installation process of the substitute 2 and improves operational convenience but also significantly enhances the connection stability and reusability durability between the substitute 2 and the model body 1, effectively solving the problems of complex installation and easy loosening in existing technologies. To address the issues of decreased accuracy and shortened lifespan, the first magnetic chuck 4 is a ring-shaped permanent magnet embedded in the center of the bottom surface of the positioning cavity 3. The second magnetic chuck 5 is a circular magnet with opposite magnetic poles to the first magnetic chuck 4, embedded in the corresponding position at the bottom of the substitute body 2. This structure, through the attraction of opposite magnetic poles between the first magnetic chuck 4 and the second magnetic chuck 5, allows the substitute body 2 to be quickly and accurately attached to the model body 1, improving installation efficiency and connection stability. Simultaneously, the combined design of the ring-shaped permanent magnet and the circular magnet enhances the magnetic contact area, improving the attraction strength and alignment accuracy, preventing the substitute body 2 from shifting or loosening due to assembly errors, effectively ensuring the stability and repeatability of the planting model during use. The guide posts 6 are cylindrical structures, located at the bottom edge of the substitute body 2. There are two guide posts symmetrically distributed, positioned on both sides of the second magnetic chuck 5. The guide holes 7 are opened on the sidewalls of the positioning cavity 3, with their axial direction aligned with the guide posts 6. This structure allows the substitute body 2 to achieve precise guidance and positioning during installation through the cooperation of the guide posts 6 and the guide holes 7, effectively preventing the substitute body 2 from deviating during insertion, ensuring the stability and repeatability of each installation, and enhancing the alignment accuracy between the magnetic chucks, thereby improving the overall assembly precision and reliability. The positioning cavity 3 is a stepped blind hole structure, including a first cavity section 301 and a second cavity section 302, wherein the diameter of the first cavity section 301 is larger than that of the second cavity section 302.This structure allows the substitute 2 to be progressively limited and stably embedded through different diameter segments during insertion. The first cavity 301 provides initial guidance and installation space for the substitute 2, while the second cavity 302 precisely accommodates and positions the guide post 6 and the magnetic suction part, thereby improving assembly accuracy and structural stability, preventing poor installation due to interference or misalignment, and further ensuring the overall reliability of the model during use. The buffer and shock absorption cavity 8 consists of multiple mutually spaced annular chambers, which are separated by a thin-walled structure to form a compressible deformation area. This structure can withstand external impacts. During frequent disassembly and assembly, the buffer and shock-absorbing cavity 8 can absorb vibration and assembly stress through elastic deformation, effectively reducing direct collisions between rigid structures and preventing damage to the substitute 2 due to excessive force. Simultaneously, it maintains the stability and reusability of the overall structure, thereby improving the model's durability and lifespan. The first magnetic chuck 4 and the second magnetic chuck 5 are pre-embedded structures. This structure not only improves the overall integration and appearance flatness of the structure but also effectively prevents the first magnetic chuck 4 and the second magnetic chuck 5 from loosening or falling off during use, ensuring the stability and durability of the magnetic connection.

[0018] Working principle: When using this installation-free substitute 3D printing planting model, first align the guide post 6 at the bottom of the substitute 2 with the guide hole 7 on the side wall of the positioning cavity 3, and slowly insert it along the axial direction. As the substitute 2 continues to be pressed down, the second magnetic suction piece 5 embedded at its bottom gradually approaches the first magnetic suction piece 4 pre-embedded in the center of the bottom surface of the positioning cavity 3. Under the action of the opposite magnetic poles of the two, they are attracted and finally fit together. At the same time, the buffer and shock absorption cavity 8 is subjected to force synchronously with the pressure inside the substitute 2, ensuring that the entire assembly process is carried out smoothly. Finally, the substitute 2 is stably fixed on the model body 1, thereby completing a series of installation operations.

[0019] Although the present invention 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
