Problems solved by technology

[0003] The existing dental implants have the following problems in use: after the implant screw is set to the root of the tooth, loosening may occur after a long period of use, and the stability of the entire implant after assembly cannot be obtained. Further improvement; at the same time, in the process of designing coatings on the surface of dental implants, its work efficiency has not been significantly improved

Embodiment 1

[0039] This embodiment provides a specific structure of a diamond-coated dental implant, such as Figure 1-3 Shown, a diamond-coated dental implant comprising:

[0040] An implant comprising an upper part 2, a middle part 3 and a lower part 4;

[0041] The abutment 1 has a screw 101 welded to its bottom, and the screw 101 is screw-fitted into the preset groove 6 inside the implant; and

[0042] At least two groups of posts 5 are plugged into the preset post grooves 7 on the surface of the lower part 4 , and one end of the posts 5 extends into the groove body 6 .

[0043] like figure 1 As shown, the upper part 2 and the lower part 4 are conical structures, the middle part 3 is a columnar structure, and the surface of the implant is coated with a diamond film layer.

[0044] In the implant mentioned above, the upper part 2 provides the function of bone expansion and initial stabilization, the middle part 3 can effectively disperse the stress, and the lower part 4 ensures the ...

Embodiment 2

[0049] The present embodiment provides a kind of preparation method of diamond-coated dental implant, comprises the steps:

[0050] Substrate pretreatment: use a grinder to grind and polish each part of the substrate to form a preliminary implant, abutment 1 and post 5;

[0051] Drilling treatment: use a drilling machine to open slots inside and on the surface of the implant, and finally form the slot body 6 and column slot 7;

[0052] Surface treatment: including but not limited to spin deposition method and acid etching sandblasting method, and chemical deposition method can also be used to coat the surface of the implant, and the surface coating treatment of titanium and titanium alloy implants, and form diamond film layer.

[0053] The specific process of substrate pretreatment is:

[0054] First, using powder metallurgy technology, Nb, Zr or Mo elements are added to medical pure titanium, and the ratio of each element to medical pure titanium is 0.01-0.2:1, thereby form...

Abstract

The invention discloses a diamond-coated dental implant. The diamond coated dental implant includes: an implant including an upper layer portion, a middle layer portion and a lower layer portion, a base table of which the bottom end is provided with a screw rod, wherein the screw rod is spirally assembled in a groove body preset in the implant, and at least two clamping columns which are assembledin column grooves preset in the surface of the lower layer part in an inserting manner, wherein one end of each clamping column extends into the groove body. The technical key points are as follows that: the diamond film layer is designed on the surface of the implant, so that the hardness of the implant can be remarkably improved, the implant can be screwed in, the surface friction force is reduced, the screwing-in process is smoother, the damage to tissues during screwing-in is reduced, cell protein adhesion can be remarkably promoted, and the osseointegration is enhanced at the same time,the clamping column is designed on the surface of the implant, and the clamping column can be extruded in the process of mounting the base station, so that the whole implant has a barb function, and the stability of the whole implant after being assembled is remarkably improved.

Description

technical field [0001] The invention belongs to the field of dental implants, in particular to a method for preparing a diamond-coated dental implant. Background technique [0002] Dental implants are surgically implanted into the upper and lower jaws of the missing teeth of the human body. After the surgical wound is healed, a device for repairing dentures is installed on its upper part. The core of dental implants lies in the implant part, which is equivalent to the root of the real tooth and plays a vital role in the fixation of the entire tooth. [0003] The existing dental implants have the following problems in use: after the implant screw is set to the root of the tooth, loosening may occur after a long period of use, and the stability of the entire implant after assembly cannot be obtained. Further improvement; at the same time, in the process of designing the coating on the surface of the dental implant, its work efficiency cannot be significantly improved. Conte...
