A zirconia dental crown is made of zirconium dioxide—a high-strength ceramic. Its extraordinary strength helps it protect severely damaged or decayed molar teeth. Dr. Siny Thomas of Sugar Land provides durable, natural-looking restorations with zirconia crowns.
When Are Zirconia Crowns Used?
Dr. Thomas uses zirconia crowns for molar teeth and bridges. In high-stress situations, monolithic zirconia is used. Where the stress demands aren’t so great, zirconia overlaid with porcelain can be used to provide a higher level of aesthetics. Characteristics of the crowns include:
- Durability – They are extraordinarily strong and can withstand the forces of chewing and grinding food on molar teeth.
- Metal-free – If you have metal allergies or sensitivities, there’s virtually no risk of a reaction to a zirconia crown.
- Versatility – Zirconia is available in a variety of tints and opacities to match your natural teeth. When porcelain is layered over the zirconia, a high level of aesthetics is possible.
Zirconia Crowns vs. Porcelain Crowns
- Porcelain is a ceramic that can mimic the appearance of natural teeth so closely that it can be impossible to distinguish a porcelain crown from a natural tooth.
- It’s not as strong as zirconium dioxide.
- Some porcelain crowns are fused to a metal foundation to strengthen them. But the metal creates an opaque restoration and the metal eventually shows through as a dark line at your gumline.
- Zirconia alone is not as natural-looking as porcelain. But a ceramist can layer porcelain and bake it onto the crown to match the color and translucency of your natural teeth and produce beautiful results.
- It’s a high-strength ceramic—stronger than other dental ceramics.
- A zirconia core provides a strong, metal-free foundation for a crown that won’t show through at your gumline.
What’s the Process?
Several steps are involved in receiving a dental crown:
- Dr. Thomas will file and reshape your tooth so the crown will fit over it.
- We will scan your teeth and take digital impressions of them.
- We’ll send instructions and the digital impressions to Dr. Thomas’s ceramist, who will make a precisely fitting crown for you.
- Meanwhile, you’ll wear a temporary crown.
- When your zirconia crown is ready, Dr. Thomas will remove the temporary one, clean your tooth, and bond the permanent crown to it.
- He’ll check your bite and ensure the crown fits well.
- When you approve the color and fit of the zirconia crown, Dr. Thomas will bond it to your tooth.
How to Care for a Zirconia Crown
- Brush your teeth twice daily and floss between your teeth to remove bacteria and protect them from decay.
- Avoid using your teeth to open or bite hard objects.
- Keep your regularly scheduled appointments for dental cleanings and exams.
- Let us know if you clench or grind your teeth. Dr. Thomas can provide you with a customized night guard to prevent damage to your teeth and crown.
