Problems solved by technology

The current implants often fall off within a few days after the implant is placed. Because there is a certain gap between the implant and the prepared hole after screwing in or early bone resorption due to extrusion, the implant cannot maintain a stable state.

Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0031] The preparation method of the medical implant of this example is as follows:

[0032] 1) Two kinds of molds are firstly prepared, and the schematic diagrams of mold 1 and mold 2 are obtained by modeling and designing after scanning the shape of the standard implant, and the glass mold 1 and the stainless steel mold 2 are constructed. Composition, after the two parts are molded together, a groove matching the surface of the implant is formed, and the internal contact surface is smooth....

Abstract

The invention discloses a medical implant and a preparation method thereof. The method comprises the following steps: firstly, constructing a special memory deformation high polymer material with pores, then fixing the special memory deformation high polymer material on the surface of an implant body, and carrying out volume expansion on the memory deformation high polymer material under illumination or temperature stimulation to obtain the degradable expansion implant. Compared with an existing medical implant, the implant is jointly composed of an outer-layer deformable material and an innerimplant body, and after the implant is implanted into sclerotin, the outer-layer high polymer material of the implant expands in a manual regulation and control mode, so that the high initial stability of the implant is achieved. Due to the degradability and the growth factor carrying capacity of the material, the synthesis of bone cell alkaline phosphatase and the deposition of calcium-containing minerals can be effectively promoted, and osteogenesis is induced, so that the rapid and effective osseointegration effect of the implant is finally realized.

Description

technical field [0001] The invention relates to a medical titanium implant and a method for preparing the surface functional structure thereof. Background technique [0002] In the 1960s, the Swiss biologist Branemark discovered that the implanted titanium metal can be firmly combined with the rabbit bone. In addition, it has strong mechanical properties, biocompatibility and corrosion resistance. Titanium metal implants It is widely used in bone-related aspects and has a great application prospect. [1] [0003] However, the success of implant placement has an extremely important relationship with its early primary stability. In the current research, the growth-promoting factor coating is added to the surface of the implant in a biological way to promote the early osseointegration of the implant to achieve stronger initial stability. Most of the research is through suitable modification of the surface of titanium metal, so as to make it beneficial to the rapid surface adh...
