specific Embodiment approach 1

[0041] Embodiment 1: This embodiment is a method for preparing a pure titanium oral implant micro-arc oxidation-dopamine-coupled traditional Chinese medicine coating, which is specifically carried out according to the following steps:

[0042] 1. Surface pretreatment of the pure titanium sample: roughly grind the surface of the pure titanium sample to be treated with sandpaper, then use acetone and distilled water to ultrasonically for 25 minutes each, blow dry, put it in a sealed bag and seal it for later use;

[0043] HF acid, concentrated HNO 3 Mix evenly with deionized water to obtain a mixed acid, put the dried pure titanium sample into the mixed acid and soak for 20s to 40s to obtain a pure titanium sample after acid treatment; the mass concentration of the HF acid is 40 %~44%; the concentrated HNO 3 The mass concentration is 65%; the HF acid and concentrated HNO 3 The volume ratio is 1:2, and the volume ratio of the HF acid and deionized water is 1:3;

[0044] 2. Con...

specific Embodiment approach 2

[0049] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the concentration of sodium silicate in the micro-arc oxidation electrolyte described in step 2 is 5g / L, and the concentration of potassium hydroxide is 5g / L, The concentration of potassium fluoride is 6g / L, and the concentration of sodium phosphate is 14g / L. Others are the same as the first embodiment.

specific Embodiment approach 3

Abstract

The invention discloses a preparation method for a micro-arc oxidation-dopamine coupling carried traditional Chinese medicine coating of a pure titanium oral implant and relates to a preparation method for a pure titanium oral implant. The preparation method disclosed by the invention aims to solve the technical problem of implantation failure as an existing titanium oral implant is slowly healed in the early implanting period and bacteria invade after implantation to lead to early infection after an implant surgery. The preparation method provided by the invention comprises the steps of: I, pre-treatment of the surface of a pure titanium test sample; II, preparation of a micro-arc oxidation electrolyte; III, ultrasonic micro-arc oxidation treatment; and IV, post-treatment. After micro-arc oxidation on the surface of a pure titanium implanting material, the material is modified by taking dopamine as a coupling agent carrying traditional Chinese medicines, so that growth and development of skeleton are promoted, material metabolism of human cells is enhanced, aging of muscles and skeleton is prevented, and the broad-spectrum antibacterial action is improved, and therefore, a novel bone implant which is better in biocompatibility and faster to heal is obtained.

Description

technical field [0001] The invention relates to a preparation method of a pure titanium oral implant coating. Background technique [0002] With the increase of trauma such as bone injury and bone defect and the improvement of human living standards, problems such as bacterial infection caused by implantation of oral implants for bone repair have gradually attracted people's attention. Compared with natural teeth, implant dentures have their particularity. The implant cuff is the oral soft tissue that surrounds the implant where the implant penetrates the gums. The junctional epithelium here mainly acts as a barrier and forms a good biological seal around the implant. However, compared with natural teeth, the junctional epithelium at the cuff of the implant is attached thinner, so its barrier effect is relatively weak. In addition, there are fewer blood vessels in the connective tissue around the implant than in natural teeth, and the bonding interface between the implant a...
