For a long time, porcelain teeth have been a fast and effective way to restore teeth, but the metal ions of metal porcelain teeth can produce adverse reactions to the human body, such as blackened gums and bleeding and receding gums. Metal teeth may interfere when patients do CT or MRI, so the dental medical community has been trying to change this state, and currently the international dental community is popular for porcelain teeth without metal crowns - zirconia block series.

Are zirconia blocks safe?

Zirconia for medical and dental use has an excellent bio-safety profile. Over the years, numerous experiments and clinical cases have demonstrated that zirconia has no toxic damage to bone or soft tissue cells.

Non-metallic

Zirconia is sometimes mistaken for a metal. This is a confusion of the chemical concepts of metallic elements and metals. Zirconia is not a zirconium metal or zircon, but is an oxide ceramic, although it contains metallic elements. 

Radioactivity

Patients are concerned about whether zirconia is radioactive. In fact, zirconia, the source of zirconia, undergoes several steps such as purification treatment and powder processing, and the processing removes all impurities. The State Food and Drug Administration standards have strict criteria for all ceramic materials listed, and only after meeting the radioactivity test requirements can they be used as medical materials. Experiments have shown that pure zirconia powders are not only less radioactive than glass ceramics, but even less radioactive than human bone tissue.

Does zirconia cause erosion?

All-zirconia restorations are a good choice for patients who have a tight bite and do not have enough space for tooth preparation. You do not have to worry about excessive wear on the jaw teeth because the abrasive properties of zirconia depend on the smoothness of the surface, not the hardness. Therefore, zirconia restorations, when polished or enameled, do not cause excessive wear to the jaw teeth, and you can ask your technician to enamel or polish them yourself after adjustment.

We also have other materials for dental usage such as PMMA blocks and welcome your visit.

How long does a zirconia crown last?

The skill level of the surgeon is an important factor in determining whether the crown is well made or not. In addition to the doctor, the following points also determine the life span of a crown.

1. Usage

People who eat bread every day and people who eat ribs every day will definitely have a different tooth life. Porcelain teeth are most afraid of contact with things that are too hard.

2. Material quality

When all other things are equal, choose high-quality materials can last longer. The zirconia material sold by HONCHON SMILE is better, with a better fit and less irritation to the gums.

3. Daily care

Just like you have to take care of your car regularly after you buy it, so do porcelain teeth. If you don't brush your teeth properly every day, your teeth will be more likely to loosen and fall out. Remember to maintain a clean mouth!

STC zirconia blocks are pre-colored zirconia with higher translucency and high strength for making posterior bridges and crowns, full crowns and dental crowns. ST pre-colored zirconia blocks maintain high transparency and do not require staining, saving time and cost. If your hospital is in need, please contact us for purchase.
