Placing dental crowns is a common restorative procedure in dentistry. Advances in dental technology have given patients various options for dental crowns such as standard porcelain fused to metal, metal-free composite and metal-free zirconia crowns. All types of crowns are successful in restoring teeth to their intended function, but metal-free zirconia crowns offer several additional aesthetic and functional benefits for patients.
Enhanced Appearance
Zirconia crowns are nearly identical in appearance to natural teeth. This metal-free material is ideal for restorative work in the smile zone, where metal hues are often visible through ultra-thin natural tooth enamel. Zirconia crowns can also be stained to match the color of a patient’s surrounding teeth
Improved Strength
Zirconia is a strong, durable material that is capable of withstanding a wide range of biting and chewing forces. This makes it an excellent choice for restoring back teeth, like molars, that are exposed to significant force due to normal function.
Longevity
In addition to its strength and aesthetic advantages, zirconia dental crowns are often long-lasting restorations. With proper care, these crowns can last up to 15 years or longer, making them a cost-effective solution for replacing missing or damaged tooth structure.
Other Advantages
- Biocompatibility – Zirconia is a biocompatible material that is not rejected by the body.
- Safety – This metal-free material is safe to use in patients who are metal-allergic.
- Minimal preparation – Zirconia crowns require less removal of the existing tooth structure during placement, resulting in a more conservative approach to restorative dentistry.
- Plaque resistance – Non-porous zirconia resists development of plaque buildup, making it easier to maintain dental health.
In conclusion, zirconia crowns provide beautiful and long-lasting tooth restoration for patients seeking to improve the function and appearance of their smiles. Patients should discuss their concerns with their dentist to select the best option for their particular needs.
