Data research shows that the micro morphology and physical and chemical properties of implant surface treatment technology are the main factors affecting bone bonding. Next, let's take a look at the domestic and imported mainstream surface treatment technologies.

1. Large particle sandblasting and acid etching surface treatment technology (SLA)

Swiss Zhuoman is a Swiss Zhuoman, and many brands still use this technology.

It is mainly to impact the surface of the implant with 0.25-0.5mm or so corundum particles under high pressure with high-speed airflow, and then put the implant into the mixture of high-temperature hydrochloric acid and sulfuric acid for acid etching to produce multidimensional structures that are easy to attach, such as bone cells and fibrinogen.

2. Anodizing surface treatment technology

The technology was developed by Swedish Norpak.

Anodizing is mainly to put the implant as an anode into the electrolyte, and then to form a multi-dimensional micro structure from an average thickness of 17-200nm to an average thickness of 600-10000nm on the surface of the implant.

3. Hydrophilic surface treatment technology

Generally, the implant surface is in a hydrophobic state, which is not conducive to the rapid attachment of osteoblasts and blood cell growth factors.

The implants treated by hydrophilic surface treatment technology can accelerate the attachment of osteoblasts and growth factors in blood cells, and accelerate bone bonding.

The technique is to put the implant into sodium hydroxide solution after large particles are sandblasted and etched to obtain a hydrophilic surface.

4. Plasma spraying surface treatment technology

This technology generally uses ossifying bone chemicals such as hydroxyapatite or hydroxyapatite β - tricalcium phosphate to obtain better biological cleanliness and humidity.

Hydroxyapatite has good biocompatibility, low immunogenicity, corrosion resistance and other characteristics, which can promote early bone formation.

The implant surface combined with nano material spraying technology is more conducive to the attachment of osteoblasts, thus improving the osseointegration.

5. Laser engraving surface treatment

At present, only the Laser lok planting system of American Brilliant adopts implants in this technology.

The basic principle is to treat the surface of the implant neck with laser engraving technology to form a microbial closed channel, inhibit the downward growth of epithelial cells, and promote the attachment of bone cells and soft tissues to a certain extent.

These are the five implant surface treatment technologies used in clinical practice. Let's take a look. The doctor and alveolar bone need to decide which one you are suitable for after various examinations.
