When the time comes to choose a dental implant material, there are many things to consider. Aesthetically, you want an implant that matches your natural teeth, without grey showing through or any other discoloration. In terms of durability, you do not want to have an implant replaced every other year. Any implant you get should also be affordable. While zirconia implants may be a little more expensive than some other choices, they more than make up for it in terms of appearance and longevity.
What are zirconia implants?
Zirconia dental implants are a type of implant that is strong, natural-looking, and built to last. They are made of zirconium oxide, a durable material that is highly compatible with the body. For some patients who cannot tolerate metal, zirconia implants may be their best option.
Zirconia implants can be either solid or layered.
Solid zirconia implants (also called monolithic zirconia) are best used on molars. Their appearance is more opaque. Less light reflecting through and off the solid zirconia makes them look a bit less natural. The strength of solid zirconia dental implants, however, is good for hard chewing surfaces and makes up for their slightly artificial appearance. Patients who grind their teeth are also good candidates for this type of zirconia crown.
Layered zirconia implants are the most natural-looking option. These are easy to match to adjacent teeth and still offer superior strength and durability. Light reflects through these implants, making them resemble their neighboring teeth. Because they are applied in thin layers, these zirconia implants need more clearance (more space to work) and are generally used for teeth in the front of the mouth.
Zirconia is just one of several implant materials patients can choose from. Other types of implants are:
- Porcelain
- Ceramic
- Metal
- A combination of materials
What are the different types of zirconia implants?
There are two main types of dental implants: endosteal implants and subperiosteal implants.
Endosteal implants
Your dentist will surgically insert this type of implant directly into the jawbone. Once this heals, a second surgery attaches a post to the implant.
They’ll then attach the replacement zirconia tooth or teeth to this post.
Subperiosteal implants
Consisting of a frame fitted on the jawbone below the gum tissue, this type of implant becomes fixed to the jawbone as it heals. Posts attached to this frame stick out from the gum, and the tooth, bridge, or denture is snapped into place.
Dentists can use zirconia implants to replace single teeth or a group of teeth. Unlike other implant materials, zirconia dental implants can be made as one piece for those patients who cannot tolerate any metal. Zirconia dental implants are also available in two separate pieces, with a standard metal implant and post and a tooth or teeth made from zirconium.
Do I need zirconia implants?
Common uses for zirconia dental implants include:
- Implant supported dentures: These can be supported with more than one implant that runs the course of the denture, or simply by implants on either end.
- Dental bridge: While bridges can be supported on either end with a crown, some patients will opt for implant-supported bridges.
- Single tooth replacement: Zirconia implants are a great option to replace a single missing tooth. Their natural appearance is custom-made to blend in with the surrounding teeth, and the implant stimulates and protects bone growth in your jaw.
How long do zirconia implants last?
Zirconia implants are strong and durable.
With proper care and regular check-ups, it is possible for zirconia implants to last anywhere from 20 to 30 years.
What are the benefits of zirconia implants?
The major benefit to zirconia implants (after their durability) is the way they react with the body. Zirconia implants are made of a biocompatible material that virtually eliminates the possibility of an adverse reaction. Metal-free dental implants are a great choice for patients who have had adverse reactions in the past.
For some people, the metal lining of a porcelain implant means that the implant can cause irritation and other complications. The metal lining of a porcelain implant may also appear above the crown at the gumline. Although it does not matter so much in terms of molars, this dark metal line is not the best look for front teeth. Zirconia implants are natural-looking and appropriate for both front and back teeth.
Some might argue in favor of strong all-metal implants, but again, this is not necessarily appropriate for front teeth. Most patients will prefer implants that blend seamlessly with their natural teeth, and zirconia implants are the best choice in that regard.
Are there any zirconium implant problems?
For people who choose to avoid metal entirely, one major issue that may arise for zirconia implants is the fact that all-zirconia implants (posts and replacement teeth) are manufactured as one piece (instead of as two pieces as with other implant materials). This makes the placement of zirconia implants very important, as adjustments can be challenging.
Another issue with all implants is that the patient must have adequate jawbone to accept an implant. A benefit to implants is that once placed, bone growth is stimulated, but the jawbone must have enough one to begin with.
Finally, while zirconia is the Cadillac of metal-free implants, its strength is also a potential weakness. As with porcelain crowns, zirconia’s strength may cause damage to the opposite teeth.
How much do zirconia implants cost?
It is challenging to pinpoint the exact cost of zirconia dental implants. Many factors contribute to the price, including the location of the dentist, their level of experience, and the amenities they offer.
What should I get?
The best implant to get is the one that works for you, your dental needs, and your budget. Each patient is individual and needs to make the decision about which implant to get in consultation with their dentist.
