Positives and Negatives of Zirconia Implants At Nashville Center for Aesthetic Dentistry – Dr. Dennis Wells we can help guide you to the best decision on tooth implants. According to an article in Periodontology 2000, zirconia dental implants have several advantages:
- Zirconia bonds better with gum tissue and is more biocompatible.
- Zirconia implants have a much lower bacterial attraction.
- Zirconia has good strength and fracture resistance.
- Zirconia holds up against wear and corrosion very well.
- Zirconia is more desirable cosmetically because it matches closer to tooth color.
However, there are some drawbacks to zirconia dental implants, as the same article notes:
- Sometimes the material can deteriorate over time and develop tiny cracks.
- Zirconia is usually only available as a one-piece implant. If a patient requires an angled abutment to correct alignment, they may need to choose a metal option.
- Any grinding on the surface of the implant can weaken the structure.
- Failure rates of zirconia implants have yet to be discovered.
Pluses and Minuses of Titanium Implants There are several advantages in choosing to use a titanium implant, the article continues:
- Titanium implants are readily available in a two-piece version, which helps to angle the crown for correct implant positioning.
- The failure rate of titanium implants is estimated to be significantly lower than that of zirconia implants.
- Titanium has a high resistance to corrosion and excellent biocompatibility with the bone and gum tissues.
However, there are also several disadvantages associated with titanium implants:
- A titanium implant may fail if there is an allergic reaction to the metal.
- Metal ions released from titanium can cause local inflammation and irritation in some patients.
- If the tissue around the implant is thin, the dark metal may show through.
With proper maintenance, titanium or zirconia dental implants can last for many years, typically for at least five years, but most are likely to have a much longer life. To increase the lifespan of your implant, keep up with a regular oral hygiene routine, avoid smoking, and get regular dental checkups. Choosing the right implant material for you is an important decision. Discuss your options with your dental professional, and make sure you speak to your insurance provider as well in order to find the best solution.
