Since they were first approved in 2001 by the FDA, zirconia dental implants
have been used by more and more dentists. Zirconia implants have been
used in Europe for more than a decade because they have shown excellent
biocompatibility and stability in patients. In this blog, we explain some
of the pros and cons of zirconia
dental implants so that you can decide if these implants are right for you.
Pros of Getting Zirconia Dental Implants
If you are interested in getting dental implants but you are worried about
metal-free dentistry, zirconia implants might be a viable option for you.
Zirconia is a completely inert material that is useful for people who
have metal allergies or sensitivities. Zirconia implants eliminate the
risk of having dark lines appear around the gum, which gives these implants
an aesthetic appeal.
At first, the implants were only available as a one-piece implant, but
two-piece zirconia implants have since been introduced. The two piece
implants allows for abutments to be fully customized. A metal-free zirconia
implant can be a healthier option for gum tissue because the material
retains less plaque and calculus than titanium. This is especially true
when a patient selects a one-piece zirconia implant.
Zirconia has a solid flexural strength and is known to be tougher against
fractures than other types of ceramics. Because of its white color, low
modulus of elasticity, and low thermal conductivity, zirconia has become
a popular choice for implants among dental professionals. Studies have
shown zirconia to be as good as or even better than titanium in terms
Cons of Getting Zirconia Dental Implants
One drawback to zirconia dental implants is low-temperature degradation
as the implant ages. This can sometimes result in the mechanical properties
of the zirconia becoming degraded, which reduces the strength, density,
and toughness of the implant. There haven’t been many studies published
about the long term success of the implant. Because there hasn’t
been much research regarding two-piece zirconia dental implants, a dentist
might prefer using one-piece dental implants instead.
