Embodiment 1

[0042] refer to Figure 1-Figure 5 As shown, this embodiment provides a dental implant, comprising: a dental implant body, a porous layer 1 is arranged outside the dental implant body; the porous layer 1 includes at least one hollow polyhedral structure 2, and the surface of the hollow polyhedral structure 2 has a The hollow cavities of the hollow polyhedron are connected micropores. Among them, refer to Figure 4 and Figure 5As shown, the porous layer 1 in the present invention is composed of a hollow polyhedron 2 with micropores on the surface. By setting the structure of the porous layer 1 to replace the rough surface in the prior art, the strength and osseointegration efficiency of the dental implant are greatly improved.

[0043] Specifically, refer to Figure 1-Figure 3 As shown, the porous layer 1 in this embodiment includes multiple hollow polyhedral structures 2, and the multiple hollow polyhedral structures 2 are sequentially distributed along the circumferential...

Embodiment 2

[0062] This embodiment provides a dental implant manufacturing method for manufacturing the dental implant in Example 1, which specifically includes the following steps:

[0063] S1: Use the DICOM modeling method, use CT technology to photograph the edentulous mandible, obtain the corresponding CT data, and use the medical image software Minics, reverse engineering software Geomagic and 3D design software SolidWorks to establish a model including the edentulous mandible, mucosa and the first three-dimensional finite element model of the denture;

[0064] S2: Through the drawing of the dental implant, each part of the three-dimensional model of the dental implant is established in SolidWorks, and assembled to form a second three-dimensional finite element model of the dental implant;

[0065] S3: Assemble the first three-dimensional finite element model in step S1 with the second three-dimensional finite element model in step S2 to obtain the required third three-dimensional fi...

Abstract

The invention provides a dental implant and a manufacturing method thereof. The dental implant comprises a dental implant body, and a porous layer is arranged outside the dental implant body; and the porous layer comprises at least one hollow polyhedral structure, and micropores communicating with a hollow cavity of the hollow polyhedral structure are formed in the surface of the hollow polyhedral structure. The dental implant provided by the invention solves the problems of slow healing speed, easy falling of the dental implant and easy implantation failure caused by overlarge elastic modulus of the surface of the dental implant and bone tissues in the prior art. According to the manufacturing method of the dental implant, the dental implant is manufactured by adopting 3D printing, so that the processing precision and the product stability are ensured, the processing cost is also greatly reduced, the step of surface roughness treatment in the prior art is avoided, and the influence on the mechanical property of the dental implant in the processing process is avoided.

Description

technical field [0001] The invention relates to the technical field of oral implants, in particular to a dental implant and a manufacturing method thereof. Background technique [0002] Tooth loss will cause difficulty in chewing, increase the burden on the digestive tract and even endanger the health of periodontal tissue. It will also lose support for the soft tissue of the maxillofacial region, which is not conducive to pronunciation and aesthetics. With the rapid development of modern stomatology technology, artificial dental implants have become an important means of repairing missing teeth. With the rapid development of implant technology, dental implants are widely used in the field of dental restoration to compensate for missing teeth. [0003] In order to ensure that the dental implant has sufficient strength and osseointegration ability, the implant is made of stainless steel or titanium alloy, so that it has good biocompatibility, mechanical properties and corros...
