Embodiment 1

[0028] Please refer to the attached Figure 1-3 , the purpose of this embodiment is to provide a dental implant with an osteoinductive structure, comprising: a solid part 1, a trabecular bone part 2 and a tantalum coating part 3; the solid part 1 has a top and a root, and the top of the solid part 1 The abutment part 4 is integrally formed; the total length from the top to the root of the solid part 1 is 6 mm, the diameter of the cylindrical part of the solid part 1 is 5 mm, and the conical diameter of the root of the solid part 1 is 3 mm. Preferably, the diameter of the abutment part 4 is larger than the diameter of the solid part 1, and the inconsistency between the two diameters can realize stress transfer and avoid stress concentration.

[0029] Specifically, the root of the solid part 1 is conical threaded and has a conical band structure. The root is not only a threaded structure, but the conical band is provided with three cutting edges. The screwing in has a self-tappi...

Embodiment 2

[0034] Please refer to the attached Figure 1-3 , the purpose of this embodiment is to provide a dental implant with an osteoinductive structure, comprising: a solid part 1, a trabecular bone part 2 and a tantalum coating part 3; the solid part 1 has a top and a root, and the top of the solid part 1 The abutment part 4 is integrally formed; the total length from the top to the root of the solid part 1 is 20 mm, the diameter of the cylindrical part of the solid part 1 is 8 mm, and the conical diameter of the root of the solid part 1 is 3-5 mm. Preferably, the diameter of the abutment part 4 is larger than the diameter of the solid part 1, and the inconsistency between the two diameters can realize stress transfer and avoid stress concentration.

[0035] Specifically, the root of the solid part 1 is conical threaded and has a conical band structure. The root is not only a threaded structure, but the conical band is provided with three cutting edges. The screwing in has a self-ta...

Abstract

The invention relates to the technical field of medical devices and provides a dental implant with an osteoinductive structure. Comprising: a solid part, a trabecular part and a tantalum coating part; the top of the solid part is integrally formed with an abutment part and a root part; the solid part has a spray-coated rough surface, and the rough surface forms irregular pores structure, a trabecular bone part is provided on the irregular pore structure, and the tantalum coating part is 3D printed on the trabecular bone part of the solid part; three self-tapping holes are provided on the root blade. The beneficial effects of the present invention are: the solid part is formed with an irregular pore structure, which increases the contact area with normal bone; the porous trabecular bone structure is conducive to the growth of new bone, providing sufficient space for blood vessel regeneration and new bone regeneration, Guarantee the stability of the implant in the later stage; tantalum metal is sprayed on the implant, and its good biocompatibility shortens the process of osseointegration and accelerates the rate of clinical osseointegration.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dental implant with an osteoinductive structure. Background technique [0002] Titanium alloy has the characteristics of small specific gravity, high specific strength, low elastic modulus, easy processing and forming, and rich raw material resources. It has now developed into an ideal functional structural material for surgical implants. However, the complex internal environment of the human body will cause corrosion of metal materials and release of toxic elements, thus reducing biocompatibility; for titanium and titanium alloy dental implants, only surface osseointegration can be formed slowly, and rapid bone ingrowth cannot be formed. Make the planting cycle longer, it is difficult to realize immediate planting. In addition, for middle-aged and elderly people with poor alveolar bone quality and osteoporosis, the initial implantation stability of titanium and titani...
