What are the properties of dental zirconia blocks？

Dental zirconia block as an advanced dental repair material, its performance is very excellent, which is reflected in the following aspects:

First, physical properties

1. High strength: Zirconia has a high bending strength, far exceeding the national standards for dental materials, and can withstand a large bite force, making the restoration more durable.

2. High hardness: The hardness of zirconia is also very high, close to the hardness of natural teeth, which makes it excellent in wear resistance and corrosion resistance.

3. Good toughness: zirconia material has a unique rupture resistance and strong curing properties after rupture, even when subjected to greater external force is not easy to break.

Second, chemical properties

1. Stability: Zirconia shows good chemical stability in the oral environment, and is not easy to react with acid and alkali substances in the mouth, so as to maintain the long-term stability of the restoration.

2. Biocompatibility: Zirconia is a non-toxic material that is non-irritating to oral tissue and does not cause problems such as allergic reactions or gum inflammation.

Third, aesthetics

1. Good transparency and refraction: zirconia porcelain teeth have good transparency and refraction, similar to the color and gloss of natural teeth, and the repaired teeth are very natural in terms of aesthetic effect.

2. Adjustable color: The color of zirconia porcelain teeth can be customized according to the color of the patient's teeth to achieve a more natural and beautiful effect.

Fourth, processing performance

1. Easy to process: Zirconia materials can be precisely machined by CAD/CAM technology to make the shape, size and thickness of the prosthetics precisely in line with the patient's oral condition.

2. Good edge tightness: The edge tightness of zirconia porcelain teeth is good, which can effectively prevent bacterial penetration and secondary caries.

In summary, dental zirconia block has excellent performance in physical properties, chemical properties, aesthetics and machining properties, and is an excellent dental repair material.
