Embodiment Construction

[0018] Such as figure 1 Shown is the two-stage implant of the present invention, comprising a body 1 and an abutment 2, the surface of the abutment 2 located above the top of the body 1 is provided with a first microporous area 3, and the first microporous area 3 is provided with There are first micropores 31 uniformly arranged, and the size of the first micropores 31 is 1-3 microns, and there are smaller nanoscale second micropores 32 evenly distributed in the first micropores 31, and its structure is as follows: figure 2 shown. image 3 is the scanning electron microscope image of the part of the abutment through the gingiva, where A is the smooth surface, the fiber cells are arranged in parallel, when the first micropore area 3 is set, as image 3 As shown in B, the surface is dimpled, and fibrous cells adhere to grow vertically or angularly, indicating that the design of micro- and nano-scale micropores on the surface has no obvious effect on early cell proliferation, bu...

Abstract

The invention discloses an implant for improving the sealing performance of soft tissue around the implant. The implant comprises a body part and a base foundation or a neck part, wherein the base foundation is connected with the body part through a screw; the neck part is integrally connected with the body part; the upper part of the body part matches with the bottom of the base foundation to form a shoulder foundation of 0.2-0.7mm wide; a first micro pore zone of 3-5mm wide is arranged on the implant; first micro pores which are uniformly distributed are formed in the first micro pore zone;the size of the first micro pores is 1-3 micrometers; the surface of an area above the first micro pore zone is a smooth surface; and the first micro pore zone is positioned on the surface of the basefoundation or the neck part above the top of the body part. The implant emphasizes on creativeness of the sealing performance of a gum threading part of the implant, the adhesiveness of soft tissue to the implant is improved, mucosal inflammation around the implant and peri-implantitis can be reduced, and the long-term success rate of implanting can be increased.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a dental implant. Background technique [0002] Implant restoration technology has been around for nearly 70 years, and it is increasingly accepted by patients with missing teeth due to its advantages of beauty, comfort and good function. After Professor Brannmark proposed the theory of osseointegration in 1952, various methods of enhancing osseointegration came into being gradually, making the success rate of implantation higher and higher. However, the occurrence of peri-implantitis often leads to implant loosening or even falling off, eventually leading to implant failure. It often starts from the initial peri-implant mucositis, and the bacteria gradually invade the soft tissue around the implant, causing the junctional epithelium to move to the root, leading to alveolar bone resorption, and even directly penetrating the combination of the implant and soft tissue, result...
