What is the difference between dental zirconia block and metal porcelain teeth

Dental zirconia blocks and metal porcelain teeth are two different dental restoration materials, and there are several major differences between them:

1. Material:

Dental zirconia block: Mainly made of zirconia, it is an all-porcelain material and does not contain metal components. It has good biocompatibility and high strength, high wear resistance.

- Metal porcelain teeth: the inner crown is made of metal and the outer is covered with porcelain. The metal composition can be precious metals (such as gold alloys), titanium alloys or other alloys. Metal porcelain teeth may have different characteristics depending on the type of metal.

2. Aesthetics:

- Dental zirconia blocks: Due to the all-porcelain nature of zirconia, its color and light transmission are very similar to natural teeth, providing a high degree of aesthetic effect.

- Metal porcelain teeth: Although the outer layer of porcelain can improve the aesthetic, due to the metal structure of the inner layer, it may affect the transmission of light in some cases, resulting in a slightly lower aesthetic than all-porcelain materials.

3. Biocompatibility and comfort:

Dental zirconia blocks: have excellent biocompatibility, usually do not cause allergic reactions, and are not irritating to the gums.

- Metal porcelain teeth: Biocompatibility varies depending on the type of metal. Certain metals, such as nichrome, can trigger allergic reactions, such as problems with black gum lines or metal odors. The biocompatibility of precious metal porcelain teeth is relatively good.

4. Durability and maintenance:

Dental zirconia blocks: Due to their high strength and wear resistance, they are generally durable and relatively simple to maintain.

- Metal porcelain teeth: Durability depends on the metal material and manufacturing process. Some metal porcelain teeth may be broken or the porcelain layer falling off due to the combination of metal and porcelain.

5. Price:

Dental zirconia blocks: are usually more expensive due to their complex manufacturing process and high material costs.

- Metal porcelain teeth: Prices vary by metal type. The price of precious metal porcelain teeth is higher, while the price of ordinary alloy porcelain teeth is relatively low.

6. Application Scenario:

- Dental zirconia block: suitable for restoration of front teeth with high aesthetic requirements, and also suitable for areas such as rear teeth that need to withstand large bite forces.

- Metal porcelain teeth: Depending on the material of the metal inner crown, it is suitable for different oral environments and restoration needs.

In summary, dental zirconia blocks and metal porcelain teeth have significant differences in material, aesthetics, biocompatibility, durability, price and application scenarios. Patients should make comprehensive consideration according to personal oral conditions, aesthetic needs and budget.
