Everything You Need to Know About Zirconia Block Durability

Zirconia block is a high melting point metal oxide with very stable chemical properties and features such as wear resistance, high temperature resistance and corrosion resistance. Zirconia blocks can be widely used in many fields as a new type of structural and functional ceramic material due to its excellent mechanical properties such as good thermal shock resistance, high refractive index and good thermal stability.

How durable are zircon blocks? How long can a dental restoration made with zircon blocks last? Let this article reveal the answer for you.

The durability of zirconia blocks depends on the actual situation. What’s more, the durability of zirconia blocks is affected by the following factors.

1. Humidity

Zirconia blocks are very sensitive to humidity. In a high humidity environment, the corrosion resistance of zirconia blocks will be greatly reduced. This is because moisture will cause the concentration of hydroxide ions on the surface of zirconia blocks to increase, which will cause the grain boundaries of zirconia blocks to become unstable, and ultimately cause the crystal structure of zirconia blocks to change, making it less durable and even cracking.

2. Temperature

The performance of zirconia blocks is also affected by temperature. Under high temperature conditions, the crystals of zirconia blocks will undergo thermal expansion, causing the zirconia block material to deform or even break. In addition, high temperature conditions will also promote the reaction between zirconia blocks and other metal materials, which will have a negative impact on the corrosion resistance of zirconia blocks.

3. Chemical substances

Zirconia blocks will also lose their characteristics and performance in some specific chemical environments. For example, zirconia blocks will react with alkali in a strong alkaline environment and will also be affected in an acidic environment.

4. Mechanical stress

Zirconia blocks are brittle materials and are susceptible to mechanical stress. Extra force or vibration may cause the zirconia blocks to break or deform.

In recent years, zirconia blocks have also been widely used in the field of oral restorations as an excellent material for making dentures and tooth restorations. At the same time, the durability of zirconia blocks teeth also depends on many factors.

1. Individual differences

Different people's oral health conditions, chewing habits, oral health awareness and other factors will affect the durability of zirconia blocks teeth.

2. Tooth position

Zirconia blocks teeth are subjected to different pressures and frictions in the mouth, so their durability is also different. For example, the front teeth are more susceptible to external impacts than the back teeth, so their lifespan may be relatively shorter and their durability is poorer.

3. Design and production quality

The design and production quality of zirconia blocks teeth directly affects their durability. If the production process is sophisticated and the design is reasonable, the durability may be better. Therefore, when deciding to repair teeth, you should choose zirconia blocks produced by trustworthy professional brands, such as ZirChime.

In summary, the performance of zirconia blocks will be affected by various external factors. Therefore, when using zirconia blocks, it is necessary to pay attention to the environment and use conditions in which they are located to ensure their performance and durability.
