Zirconia Dental Implants – A New Innovation In Implant Technology

Dental implants have come a long way, from simple sea shell implants to modern implants that offer years of functionality and beauty, they have certainly changed the way we look at missing teeth replacement options. Today, titanium dental implants have successfully changed the lives of many people and have given them a reason to smile. Though, the success rate of titanium implants is very high, there are some people who have sensitivity to certain metals; that’s why the researchers tried to find out a metal free alternative and came up with Zirconia Dental implants. In this article by Ridgetop Dental, the best centre for dental implants in MacLean VA, we are going to read about Zirconia Dental implants-the metal free implants.

Zirconium—The Metal-Free Option

In order to address the concerns related to metal implants, several companies conducted further research into “metal-free” implants. This led to the zirconium implants.

Zirconium, which is also a metal, is just one row below titanium in the periodic table. In dental implants, it is used in the form of zirconium oxide ZrO2. Trace amounts of other metals called hafnium (Hf) and yttrium (another metal) are added to improve its properties. The fusion of these metals result in white opaque-looking product, labelled as a ceramic. For years, this material has been in use for making crowns and bridges. It fuses to bone (osseointegrated) much like titanium and is very hard and strong.

Titanium and Zirconia implants—Differences

Both materials can integrate with bone with equal success, but there are certain differences. Let’s take a look:

According to Ridgetop Dental’s dentists in Reston VA, titanium implants are made as two piece system. Two piece systems offer much more versatility, for example-they can be used for removable teeth, or screwed onto the implants.

Zirconium implants on the other hand, are made as one piece. Therefore, it is not as versatile as titanium implants. Also, there is a very little room for error, so it has to be placed with great care.

In titanium implants the implant is buried under the gum tissue, whereas in Zirconia implants it cannot be buried under the gum tissue, so healing phase can be a little tricky.

Advantages of Zirconia implants:

Zirconia implants has many advantages too-

·         No metal showing through gums
·         No corrosion
·         Thermally non conductive

Both titanium and Zirconia implants have their own advantages. Talk to Ridgetop Dental’s experts today to know about the types of dental implants in Vienna VA and which type of implant will be the most suitable for you.
