Which is better, zirconia or porcelain teeth

When comparing zirconia and porcelain teeth, we need to consider from multiple dimensions. Here's a detailed comparison of the two:

1. Material and strength:

Zirconia teeth are mainly made of zirconia ceramics, which has a very high bending strength, generally reaching 900MPa or even higher. It also has relatively good fracture toughness, which means that it can effectively resist crack growth when subjected to impact.

Full porcelain teeth are made of porcelain materials, although not as strong as zirconia, but also have higher compressive strength, and natural luster and color closer to natural teeth.

2. Aesthetics:

All-porcelain teeth have advantages in terms of aesthetics, their transparency and gloss are higher, and they are closer to the color and shape of natural teeth.

The transparency of zirconia teeth is relatively low and may be slightly inferior in aesthetics.

3. Scope of application:

Due to its high strength, zirconia is particularly suitable for use in areas such as back teeth that bear a large bite force.

Full porcelain teeth are more suitable for the front tooth area because of their excellent aesthetics, and can also be used for the restoration of the rear teeth.

4. Biocompatibility and safety:

Both have good biocompatibility and are non-irritating to the gums.

Full porcelain teeth do not contain metal and are a suitable choice for patients with metal allergies.

5. Price and durability:

The price of zirconia and full porcelain teeth is relatively high, but the specific price may vary depending on the brand, manufacturing process and other factors.

In terms of durability, both can provide long-term stable repair effects, but the specific service life will be affected by a variety of factors, such as patient oral hygiene habits, repair system quality.

In summary, zirconia and porcelain teeth have their own advantages and application scenarios. In the selection, should be based on the patient's specific needs, dental status and economic budget for comprehensive consideration. Zirconia may be a better choice for posterior tooth areas requiring high strength support; For the pursuit of higher aesthetics of the front tooth area, porcelain teeth are more suitable.
