Problems solved by technology

Compared with pure titanium, titanium alloys have higher mechanical strength, but they have the following disadvantages: ① Release of toxic ions: after titanium alloys such as Ti-6Al-4V implants are implanted in the body, they will slowly decompose after long-term contact with body fluids. Toxic ions such as Al and V are released, affecting osseointegration and endangering health; ② Poor osseointegration performance: Compared with pure titanium, there are more elements in titanium alloys, and the impact on the biological behavior of bone cells is more complicated
Low surface bioactivity, technical problems of low osseointegration effect

Embodiment 1

[0065] A pure titanium dental implant / micro-implant, comprising a titanium dental implant body, the titanium dental implant body is a pure titanium dental implant; the surface of the titanium dental implant body is provided with a surface with a certain roughness, and the roughness is like Figure 7 .

[0066] There are micron-scale pits on the surface, and the size of the pits is 98% similar to the depth.

[0067] Titanium dental implants are high-strength titanium dental implants with non-proportional extension strength R p0.2 / MPa range ≥485; tensile strength R m / MPa range≥580.

[0068] The specific steps of the preparation method are as follows:

[0069] (1) Pretreatment: The processed titanium nails (titanium dental implants) were ultrasonically cleaned successively with acetone, anhydrous ethanol and purified water, and each cleaning solution was cleaned for 20 minutes and three times.

[0070] (2) Sandblasting: The titanium nails cleaned in step (1) were blasted w...

Embodiment 2

[0077] Other contents are as in Example 1. After processing the raw materials into a certain shape, the surface is cleaned, sandblasted and acid etched in sequence to obtain a surface with a certain surface roughness, and most of the biological organisms formed in the process are retained. active molecules. Has good osseointegration effect. Titanium dental implants are high-strength titanium dental implants with non-proportional extension strength R p0.2 / MPa range ≥485; tensile strength R m / MPa range≥580.

[0078] The specific steps of the preparation method are as follows:

[0079] (1) Pretreatment: The processed titanium nails (titanium dental implants) were ultrasonically cleaned successively with acetone, anhydrous ethanol and purified water, and each cleaning solution was cleaned for 20 minutes and three times.

[0080] (2) Sandblasting: The titanium dental implant cleaned in step (1) was blasted with 60-mesh alumina fine sand for 1min under a pressure of 0.3MPa. A...

Embodiment 3

[0086]Pure titanium dental implant / micro-implant structure, including titanium dental implant body, the titanium dental implant body is provided with a base and a base, the base and the base are connected together left and right or up and down, and the base is cylindrical or has no vertebral angle The base is a cone with a parallel surface at the top; it also has milling grooves, single thread and double thread, the single thread is arranged around the surface of the base body, and the double thread is arranged around the surface of the base; there are 3 milling slots , set on the surface of the base body, from the upper surface of the single thread to the surface of the base body, from the top of the base body to the surface of the first double thread, longitudinally passing through the single thread, and dividing each single thread into three sections equally.

[0087] When the base is a cylinder, the lower surface area of ​​the base is the same as the upper and lower surface...

Abstract

The invention belongs to the technical field of titanium dental implants, and particularly relates to a pure titanium dental implant / micro-implant and a preparation method thereof. The preparation method comprises the steps that after a bracket is processed into a certain shape, cleaning, sandblasting, acid etching, re-cleaning and drying are carried out, wherein an acid etching mixed solution iscomposed of, by volume, 5.5%-6.5% of nitric acid, 3%-4% of hydrofluoric acid and 89.5-91.5% of purified water. The pure titanium dental implant / micro-implant and the preparation method thereof have the advantages that the biological surface activity of the titanium dental implant is high, the process is simple, low in cost and convenient and fast, and a better osseointegration effect can be obtained.

Description

technical field [0001] The invention belongs to the technical field of titanium dental implants, in particular to a pure titanium dental implant / micro-implant and a preparation method thereof. Background technique [0002] Dental implants are now the mainstream products that replace real teeth. They are surgically implanted into the upper and lower jaws of the human body with missing teeth. After the surgical wound is healed, a device to repair dentures is installed on the upper part. The core of dental implants is the implant part, which is equivalent to the root of a real tooth and plays a vital role in the fixation of the entire tooth. [0003] Dental implants are classified into metal and alloy materials, ceramic materials, carbon materials, polymer materials and composite materials according to their different materials. Among them, titanium and titanium alloys are the most widely used materials in clinical applications due to their good biocompatibility. Pure titaniu...
