Ceramic (Zirconia) Implants

In case of missing teeth, the dental implant is placed in the jaw bone like a tooth root and allows aesthetics and function to be restored.

Until now, the most widely used and still used implants were made of titanium material. Although titanium was thought to be tissue compatible, more and more studies began to show that its parts could spread to surrounding tissues and even elsewhere in the body by corroding. This can cause titanium to trigger inflammatory reactions in the body, especially in those with a genetic predisposition.

The arrows in the picture point to fragments of titanium detected in the tissue around the implant. These particles are perceived as “foreign” by the body and are swallowed by macrophages, and this can initiate inflammatory reactions. (source article: https://europepmc.org/article/med/29440784)

Since ceramic implants do not corrode like metals, they stand out as a more biocompatible material than titanium. Contrary to popular belief, “Zirkolith®” implants, which are obtained by turning zirconium metal into ceramic by going through processes that require extremely advanced technology, are no longer “zirconium”. Technically ceramicized zirconium is called “zirconia”.

Why Ceramic Dental Implants?

 

  • Bacterial plaque involvement in ceramic implants is extremely low. In this way, it reduces the risk of developing inflammation in the tissue around the implant.
  • The gingiva naturally tends to wrap around zirconia implants, and gingival insertion procedures, which may be required in titanium implants, are generally not required in zirconia implants.
  • This behavior of the gums is also a sign of the compatibility of the implant with body tissues.
  • Zirconia does not transmit electric current.
  • It is aesthetically more advantageous than titanium, as it is completely white.
  • When placed, it can be abraded as if it is your own tooth and taking measurements can be done. There is no need for complicated gauging and laboratory steps in titanium.
  • The success rate of ceramic implants after 5 years is over 95%.
  • Zirconia is extremely strong and can withstand twice the maximum stress and strain loads that pure titanium and titanium alloys can withstand.

On the left of the photo you can see the teeth made using titanium and ceramic implants on the right. It is possible to observe the difference in the structure and color of the gum.

Zirconia / ceramic implants combined with the general treatment principles of biological dentists in search of biocompatible materials, created their own application protocol. Before and after implant application, a preparation and maintenance phase that will ensure the good functioning of bone metabolism, and practices that will positively guide bone and soft tissue healing during the application, without using foreign grafting materials, are taken care of. In short, zirconia implant application is much more than using an alternative material.
