Problems solved by technology

[0004] Ultraviolet irradiation is a process that can activate the surface of the implant before dental implant surgery to regain the hydrophilic surface. Although the corresponding implant activation instrument can make the implant reach the hydrophilic level to a certain extent, However, it has not been widely promoted in the market. The main reason is that the activation power of ordinary UVC ultraviolet rays (wavelength 253.7nm) is low, the energy is not concentrated, and the time required for activation is long (generally more than 4 hours).
During clinical use, the doctor needs to prepare for the activation of the implant 4 hours in advance, which is cumbersome and time-consuming during the actual operation
Moreover, the implant cannot be sterilized again after it is taken out. Once the operation time needs to be changed due to reasons of the patient or the doctor, the implant cannot continue to be used, resulting in waste.

Embodiment 1

[0122] Pre-treatment: Prepare a small implant disc with a diameter of 10 mm and a thickness of 1 mm by machining, and use rutile sand to perform sandblasting on the surface of the above implant, with a sandblasting distance of 8 mm and an angle of 45°. for 15s to form a first-level hole. The surface of the implant was etched with sulfuric acid at 60°C for 60 minutes to form secondary holes.

[0123] Activation: Before the experiment, take out the pre-treated implant, and activate the small disc under the excimer lamp activator. The excimer lamp activator provides 172nm and 7.2eV photons to the implant to be activated Energy of vacuum ultraviolet light. The activation time is 1min, and the distance between the activation instrument and the small wafer is 30mm. Test immediately after activation.

[0124] Among them, the structure of the excimer lamp is as image 3 As shown, it includes an inner quartz tube A and an outer quartz tube B coaxially arranged, and an airtight annu...

Embodiment 2

[0130] Pre-treatment: First prepare a small disc with a diameter of 10 mm and a thickness of 1 mm by machining, and use rutile sand to blast the surface of the implant with a blasting distance of 8 mm, an angle of 45°, and a time of 15 seconds. A first-order hole is formed. The surface of the implant was etched with sulfuric acid at 60°C for 60 minutes to form secondary holes.

[0131] Activation: Before the experiment, take out the pre-treated implant, and activate the small disc under the excimer lamp activator. The excimer lamp activator provides 172nm and 7.2eV photons to the implant to be activated Energy of vacuum ultraviolet light. The activation time is 1min, and the distance between the activation instrument and the small wafer is 30mm. After activation, place it in the air for 15 minutes before testing.

[0132] The used excimer lamp of this embodiment is with embodiment 1.

Abstract

The invention discloses an implant activation method and an activated implant and belongs to the field of medical products. The method comprises the step of irradiating a to-be-activated implant underan excimer light source for activation treatment, wherein the excimer light source provides 148-196 nm vacuum ultraviolet with 6.3-8.4 eV photon energy for the to-be-activated implant. By use of theactivation method, a hydrophilic implant with longer hydrophilic effect retention time can be rapidly obtained before an implant surgery, besides, pollution caused by an organic carbide on the surfaceof the implant can be reduced, and the oxygen content can be increased, so that the surface of the implant can adsorb more bioactive substances and osteogenic protein, and combination of the implantwith bone is promoted. The activated implant after activation treatment has a low surface contact angle, can keep hydrophilic performance for a longer time, and has higher content of surface oxygen and titanium and lower content of polluting elements.

Description

technical field [0001] The invention relates to the technical field of medical products, in particular to an implant activation method and an activated 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 the abutment and the crown is installed on its upper part. For the modern oral cavity, dental implants are widely used in tooth loss and restoration because of their beauty, comfort and long life. They are called the third set of teeth for human beings. [0003] Hydrophilic dental implants tend to have better biological activity. A series of studies have shown that hydrophilic implants can promote the differentiation of bone cells and are especially effective for early osseointegration. However, the existing implants generally have a relatively high contact angle (above 90°), and the hydrophilicity of some hydrophilic i...
