AI Technical Summary
Existing dental implant support structures cannot flexibly adjust the crown height according to actual conditions, resulting in low flexibility and convenience in use, affecting the patient's experience, and may require reoperation to replace the implant, increasing costs and the burden on life.
Design an adjustable support structure including implant components, abutment and threaded parts. By setting up connected mounting slots and threaded holes, the crown height can be flexibly adjusted using pads and elastic elements. The elastic force of the elastic elements can be used to adjust the position of the abutment and pads to ensure that the crown is at the same height as other teeth.
This allows for flexible adjustment of the crown height based on actual conditions, improving the flexibility and convenience of dental implant use, reducing overall costs, enhancing the patient experience, and avoiding the need for repeat surgery for replacement.

Abstract
Claims
1. An adjustable support structure for a dental implant, characterized by Includes implant components, abutment, and threaded parts; The implant assembly includes a body, a pad, and an elastic element. The body has a through-hole and a threaded hole extending along its height. Both the pad and the elastic element are disposed within the through-hole, with the pad positioned above the threaded hole. The two ends of the elastic element along its length are connected to the pad and the end of the through-hole of the through-hole, respectively. The pad slides within the body. A connecting hole extends through the pad. The end of the pad away from the elastic element abuts against the abutment. The abutment is adapted to and slides within the through-hole. The end of the abutment away from the pad is connected to the crown. The base has a stepped hole through it, and the stepped hole, the connecting hole and the threaded hole are all coaxially arranged; the head of the threaded part is located in the stepped hole, and the threaded part of the threaded part passes through the stepped hole, the connecting hole and the mounting groove in sequence and is threadedly connected to the threaded hole.
2. The adjustable abutment structure for a dental implant according to claim 1, wherein Multiple elastic elements are provided, and the multiple elastic elements are distributed at intervals along the circumferential direction on the outside of the threaded hole and the connecting hole.
3. The adjustable abutment structure for a dental implant according to claim 2, wherein The body is also provided with a plurality of first blind holes communicating with the mounting groove. The plurality of first blind holes are distributed at intervals along the circumferential direction on the outside of the threaded hole. The pad is provided with second blind holes corresponding one-to-one with the plurality of first blind holes. The two ends of the elastic element in the length direction are respectively fixed to the first blind holes and the corresponding second blind holes.
4. The adjustable abutment structure for dental implant according to claim 1, wherein The body is in the shape of an inverted frustum, and the taper of the body is 5°-20°; the outer wall of the body is provided with external threads, and the external threads extend along the height direction of the body.
5. The adjustable support structure for dental implants according to claim 1, characterized in that, The diameter of the connecting hole is the same as the diameter of the threaded hole.
6. The adjustable abutment structure for dental implant according to claim 1, wherein The mounting groove is in the shape of a regular hexagonal prism; the pad is in the shape of a cylinder or a regular hexagonal prism that matches the mounting groove; When the pad is cylindrical, the side wall of the pad is tangent to all the wall surfaces of the mounting groove.
7. The adjustable abutment structure for a dental implant according to claim 6, wherein The abutment includes, from bottom to top, a first step, a second step, and a third step connected in sequence along its height direction. The first step is adapted to and slidably connected to the mounting groove. The first step abuts against the end of the pad away from the elastic element. The second step is used to contact the gingiva. The third step is used to connect the crown.
8. The adjustable abutment structure for a dental implant according to claim 7, wherein The first step is hexagonal prism-shaped, and the slope of the first step is 1°-5°. The second step is in the shape of an inverted frustum, and the slope of the second step is 15°-25°; The third step includes a first connecting segment and a second connecting segment. The first connecting segment connects the second step and the second connecting segment. The first connecting segment is cylindrical. The second connecting segment is frustum-shaped and has an inclination of 20°-35°.
9. The adjustable abutment structure for dental implant according to claim 1, wherein The threaded component is a screw, and the stepped hole includes a through hole and a tapered countersunk hole connected sequentially along the height direction of the base, with the head of the threaded component located inside the tapered countersunk hole.
