The limiting post has two symmetrically arranged limiting grooves on its outer wall, and an arc-shaped groove is formed near the bottom of the outer wall of the limiting post. Pressure plates are provided on both sides of the top of the arc-shaped groove away from the limiting groove.

[0004] The denture connection structure in the above patent has the following shortcomings: the denture structure does not have a limiting structure, which may cause the crown to shift due to hard objects during chewing, thus affecting the user's use.

[0005] Therefore, there is an urgent need to improve a denture connection structure to solve the aforementioned problems. Utility Model Content

[0015] This utility model has at least the following beneficial effects:

[0016] The crown angle is adjusted using a fine-tuning component. A tool is used to rotate the first cross groove, causing the connecting base to rotate, which in turn rotates the crown, allowing for precise adjustments. After adjusting the connecting base, a tool is used to install a fastening bolt into the fixing hole on the outer wall of the crown base. Rotating the fastening bolt causes the rubber pad at the end of the bolt to press against the rubber ring on the connecting base, facilitating adjustments to the crown angle according to the patient's chewing habits and improving patient comfort. The fastening bolt and rubber pad, used to compress and limit the connecting base, prevent the denture from shifting during use, avoiding impact on patient comfort and facilitating disassembly and maintenance. A limiting groove is also provided to limit the crown's position relative to the connecting base, preventing misalignment.

[0017] Holes are drilled in the patient's alveolar bone, and the implant is fixed to the alveolar bone. Then, materials such as bone powder are used to fill the gap between the implant and the alveolar bone. By setting several drainage holes on the outer wall of the implant, when materials such as bone powder are used to fill the holes in the implant and alveolar bone, the material can enter the drainage holes, thereby improving the connection strength between the implant and the alveolar bone.

[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] Examples, such as Figures 1-7 As shown, a denture connection structure includes an implant 1, an installation hole 16 inside the implant 1, a second cross groove 17 at the end of the installation hole 16 on the implant 1, a fine-tuning component installed in the installation hole 16, a crown 2 installed in the fine-tuning component, the fine-tuning component including a crown base 5, a through hole inside the crown base 5, a threaded lower half of the through hole of the crown base 5, a cavity 19 in the upper half of the through hole of the crown base 5, a plurality of fixing holes arranged circumferentially on the outer wall of the crown base 5 near the cavity 19, threads in the through holes, a connecting base 6 installed in the through hole of the crown base 5, a cylindrical rod in the lower half of the connecting base 6, a threaded ring 11 on the outer wall of the cylindrical rod, a first cross groove 13 on the outer wall of the connecting base 6 near the cylindrical rod; the end of the connecting base 6 is provided with The crown 2 has a first threaded hole 9 and a fixing cavity 3 at its end. The fixing cavity 3 has a through hole and a fixing bolt 4 is installed in the through hole. The crown 2 is installed on the first threaded hole 9 by the fixing bolt 4. The fine-tuning component also includes a rubber ring 12, which is installed on the cylindrical rod of the connecting base 6. The rubber ring 12 is located above the threaded ring 11 and in the cavity 19 of the crown base 5. The rubber ring 12 is made of food-grade material. The fine-tuning component also includes a fastening bolt 8, which is installed in the fixing hole of the crown base 5. A rubber pad 14 is installed on the outer wall of the fastening bolt 8. The rubber pad 14 is made of food-grade material. The connecting base 6 has several limiting grooves 10 on its outer wall near the first threaded hole 9. The bottom of the crown 2 has several square protrusions that are adapted to the limiting grooves 10.

[0029] During dental implant surgery, an opening is made in the patient's alveolar bone. Using a tool, the implant 1 is rotated through the second cross groove 17 to install it onto the alveolar bone. After a series of surgical procedures, a crown 2 matching the patient's tooth shape is fabricated. The crown 2 is then installed onto the crown base 5 using fixing bolts 4. During installation and subsequent maintenance, the angle of the crown 2 is adjusted using a fine-tuning component based on the patient's needs and the dentist's judgment. By rotating the first cross groove 13 using a tool, the connecting base 6 rotates, causing the crown 2 to rotate and achieving a fine adjustment of the 022 angle. After adjusting the connecting base 6, the angle is further adjusted by... Using a tool, the fastening bolt 8 is installed in the fixing hole on the outer wall of the crown base 5. By rotating the fastening bolt 8, the rubber pad 14 at the end of the fastening bolt 8 is pressed against the rubber ring 12 on the connecting base 6, which makes it easy to adjust the angle of the crown 2 according to the patient's chewing habits, thereby improving the patient's comfort. By using the fastening bolt 8 and the rubber pad 14 to compress and limit the connecting base 6, the denture can be prevented from shaking during use, avoiding affecting the patient's use. At the same time, it is easy to disassemble and maintain. By setting the limiting groove 10, the crown 2 and the connecting base 6 can be limited to prevent the crown 2 from deflecting between the crown 2 and the connecting base 6.

[0030] Furthermore, such as Figure 1 As shown, the implant 1 has threads on its outer wall away from the mounting hole 16, and several drainage holes 15 are arranged circumferentially on the outer wall of the mounting hole 16 near the threads. A hole is drilled in the patient's alveolar bone, and the implant 1 is fixed to the alveolar bone. Then, bone powder or other materials are used to fill the gap between the implant 1 and the alveolar bone. By providing several drainage holes 15 on the outer wall of the implant 1, when bone powder or other materials are used to fill the holes in the implant 1 and the alveolar bone, the material can enter the drainage holes 15, thereby improving the connection strength between the implant 1 and the alveolar bone.

[0031] Furthermore, such as Figure 2 and Figure 3 As shown, the end of the crown base 5 is provided with several fixing holes, in which set screws 7 are installed. The outer wall of the implant 1 is provided with second threaded holes 18, which are symmetrically arranged. The crown base 5 is installed on the implant 1 by the set screws 7. After the crown 2 is adjusted, the crown base 5 is installed in the implant 1 by rotating the set screws 7 using a tool.

[0032] like Figures 1-7 As shown, the principle of a denture connection structure provided in this embodiment is as follows:

[0033] The implant 1 is surgically installed on the patient's alveolar bone. The gap between the alveolar bone and the implant 1 is filled with materials such as bone powder. Subsequently, the patient's alveolar bone is reshaped through multiple surgeries to create a matching crown 2. Then, according to the patient's chewing habits, the angle of the crown 2 is adjusted by the doctor using a fine-tuning component. The adjustment method is to install the crown 2 on the connecting base 6 with the fixing bolt 4, and then adjust the angle of the crown 2 by rotating the first cross groove 13 with a tool. After adjusting to the appropriate angle, the fastening bolt 8 is rotated to make the rubber pad 14 fit with the rubber ring 12 to fix the connecting base 6. Then, the crown 2 is removed, and the crown base 5 is fixed in the implant 1 with the set bolt 7. The crown 2 is then reinstalled on the connecting base 6, and the fixing bolt 4 is fixed with a torque wrench. Finally, the fixation cavity 3 is filled with a specific resin.
