Embodiment 1

[0030] Step 1. The dental implants were ultrasonically cleaned twice with acetone, absolute ethanol, and purified water, each for 4 minutes, to remove oil stains on the surface of the dental implants;

[0031] Step 2. Use large particles of emery to sandblast the surface of the dental implant obtained in step 1 at a pressure of 0.4 MPa to form a micron-scale pit with a diameter of 10 μm, and then place the dental implant in acetone and 75% in sequence. Ultrasonic cleaning and drying in ethanol and distilled water;

[0032] Step 3. Put the dental implant obtained in step 2 in 0.09mol / L HF and 0.07mol / L HNO 3 The formed mixture is treated for 5 minutes, rinsed with double distilled water, and dried to form small sub-micron pits with a diameter of 0.2 μm on the surface;

[0033] Step 4. Wash the dental implants obtained in step 4 with purified water in turn, and ultrasonically clean with 5% NaHCO3 solution twice, each time is 5 minutes, with purified water, Micro90 degreasing liquid, ul...

Embodiment 2

[0035] Step 1. The dental implants were ultrasonically cleaned twice with acetone, absolute ethanol, and purified water, each for 5 minutes, to remove oil stains on the surface of the dental implants;

[0036] Step 2. Use large particles of emery to sandblast the surface of the dental implant obtained in step 1 at a pressure of 0.4 MPa to form micron-scale pits with a diameter of 12 μm, and then place the dental implant in acetone and 75% in sequence. Ultrasonic cleaning and drying in ethanol and distilled water;

[0037] Step 3. Put the dental implant obtained in step 2 in 0.1mol / L HF and 0.09mol / L HNO 3 The formed mixture is treated for 6 minutes, rinsed with double distilled water, and dried to form small sub-micron pits with a diameter of 0.3 μm on the surface;

[0038] Step 4. Wash the dental implants obtained in step 4 with purified water in turn, ultrasonically clean with 5% NaHCO3 solution twice, each time is 6 minutes, rinse with purified water, ultrasonic clean with Micro90...

Embodiment 3

[0040] Step 1. The dental implant was ultrasonically cleaned twice with acetone, absolute ethanol, and purified water, each for 7 minutes, to remove the oil on the surface of the dental implant;

[0041] Step 2. Use large particles of emery to sandblast the surface of the dental implant obtained in step 1 at a pressure of 0.4 MPa to form a micron-scale pit with a diameter of 15 μm, and then place the dental implant in acetone and 75% in sequence. Ultrasonic cleaning and drying in ethanol and distilled water;

[0042] Step 3. Put the dental implant obtained in step 2 in 0.11mol / L HF and 0.1mol / L HNO 3 The formed mixture is treated for 8 minutes, rinsed with double distilled water, and dried to form small sub-micron pits with a diameter of 0.6 μm on the surface;

[0043] Step 4. Wash the dental implants obtained in step 4 with purified water in turn, and ultrasonically clean with 5% NaHCO3 solution twice, each time is 8 minutes, with purified water, Micro90 degreasing liquid ultrasonic...

Abstract

The invention discloses a surface activation method for a dental implant. After dental implant is subjected to cleaning, sand blasting, acid treatment and secondary cleaning, a biological activity porous structure is formed on the surface of the dental implant. According to the surface activation method, mixed acid of hydrochloric acid and sulfuric acid is used for treatment, the corrosive effectof the mixed acid on titanium metal is utilized, the good surface appearance of the sand blasting dental implant is provided, thus the dental implant has the characteristic of a good rough surface, and the interface bonding strength of a dental implant scleromere surface is further improved. The acid etching effect achieved by the concentration ratio of 50%-75% of sulfuric acid and 8%-20% of hydrochloric acid is ideal, thus two or more times of acid etching steps adopted generally at present are simplified into one time to achieve the purpose, treatment time is shortened, work efficiency is improved, cost is lowered, and thus the surface activation method is suitable for commercialized production.

Description

Technical field [0001] The invention belongs to the technical field of dentistry and relates to a surface activation method of a dental implant. Background technique [0002] Dental implantology has been developed since the 1950s and 1960s, and has been very popular abroad, but the level of development in my country is relatively low. Dental implant is to plant an implant nail in the part of the patient's missing teeth, and then install the crown, which is equivalent to growing a new tooth, which is beautiful, convenient, and comfortable. It will not wear out healthy teeth like fixed teeth, and does not require the aid of hooks and trays of removable dentures. The domestic dental implant market is basically monopolized by foreign countries, and the prices are high. An important factor restricting the development of domestic dental implants is the surface treatment process of the implants. For the surface treatment process of dental implants, people have tried many methods, suc...
