Problems solved by technology

Metal parts obtained by cutting methods will inevitably destroy the original streamlines inside the metal, so the product strength of the formed parts will be reduced
In addition, through cutting and forming, the metal fragmentation generated during the cutting process will increase the cost of the product manufacturing process (the usual raw materials titanium and titanium alloys are very expensive)
Moreover, the small-diameter oral implants realized through processing are prone to fatigue and cracking in the mouth during clinical use, which is a problem that is difficult to solve by cutting technology.
In addition, the processing of oral implant systems often requires expensive processing machine tools, which also increases the cost of the processing method of the implant system.
Through the processing of the implant system, since the surface of the parts obtained by processing is usually a smooth surface, the subsequent surface treatment process is required to obtain the microscopic surface of the implant clinically required, which not only makes the processing process more cumbersome, but also the main reason for the increase in the cost of the implant. factor
[0004] In addition, oral implants completed by 3D printing are more economical in the use of raw materials, but the strength of oral implants realized by this process is limited

Embodiment 1

[0025] The embodiment of the present application provides a plastic molding mold for preparing oral implants, as shown in the attached Figure 1-5 As shown, it includes a forming die, which is used to accommodate the oral implant blank 2; a forming punch 1, which is used to extrude the oral implant blank 2 in the forming die, and includes a support seat 11 connected in sequence, a connection part 12 and forming part 13, wherein the connecting part 12 and forming part 13 are used to extrude to the inside of the blank to form the top groove of the oral implant; wherein, the inner side wall of the forming die is provided with a plurality of microscopic protrusions , used to form microscopic holes in the outer surface of oral implants. Since the surface of the parts currently processed is usually a smooth surface, subsequent surface treatment processes, such as high-speed sandblasting and impact technology, are required to obtain the microscopic surface required for clinical impla...

Embodiment 2

[0030] An embodiment of the present application provides a method for manufacturing oral implants through plastic processing of oral implant molds, the method comprising the following steps:

[0031] Step 1: Prepare titanium or titanium alloy blank;

[0032] Step 2: Place the embryo material in the oral implant mold for extrusion molding, and the deformation rate is controlled at 10 -2 S -1 -10 - 4 S -1 ;

[0033] Step 3: After the oral implant is extruded, perform stress annealing and ultrasonic cleaning;

[0034]Wherein, the inner wall of the forming die of the oral implant mold is provided with a plurality of microscopic protrusions, and the surface of the extruded oral implant has corresponding microscopic holes.

[0035] In the existing situation, usually for metal materials, there are cold processing (normal temperature forming) and hot processing (the blank needs to be formed after heating or in a heat preservation state). For pure titanium materials, under norma...

Abstract

The embodiment of the present application provides a plastic molding mold and method for preparing oral implants. The method includes a forming die for containing the oral implant embryo material; a forming punch for feeding the oral implant embryo in the forming die Material extrusion processing, including sequentially connected support seat, connecting part and forming part, wherein the connecting part and forming part are used to extrude to the inside of the blank to form the top groove of the oral implant; the inner side of the forming die There are multiple microscopic protrusions on the wall to form microscopic holes on the outer surface of the oral implant. The parts produced by this application are formed by plastic processing, and the surface of the oral implant is formed into 20-40 microns and 2-4 microns. The micron pore structure is controllable, and at the same time, the flow line of the oral implant metal is basically complete along the direction of the implant, which can increase the cost rate of the product and reduce the processing cost of the product.

Description

technical field [0001] The application belongs to the field of oral medical devices, and in particular relates to a plastic molding mold and method for preparing oral implants. Background technique [0002] In terms of the use of raw materials, oral implants mainly use pure titanium as the main raw material, or titanium alloy with titanium as the main body (the purpose of using titanium alloy is mainly to increase the strength of the product). According to the requirements of clinical use, the appearance of the product is designed to meet the application scenario. From the perspective of industrial processing, the mainstream processing method is to realize the appearance of the product by cutting the product. In recent years, 3D printing has also been used for processing. Standard implant product. [0003] The conventional processing method mainly adopts the cutting process, and the metal before cutting is usually a drawn or rolled bar or wire. From the perspective of the m...
