What is natural tooth replacement?

What is natural tooth replacement?
Published Jul 01, 2021

If you are looking forward to replacing a missing tooth, you probably come across the option of a dental implant. However, not everyone is fond of the idea of having metal in their body, especially in the mouth.

Even though titanium is a highly biocompatible material with a high success rate, new technologies have been developed for people who would like to try a more holistic approach.

Ceramic dental implants are the solution for your problem if you are looking for a healthier alternative with better aesthetic results.

In this article, we will talk about how ceramic dental implants are a healthier and holistic solution.

What is zirconia?    

Zirconium (symbol Zr) is a chemical element with the atomic number 40 that doesn’t occur in nature in its pure form but is mixed with silicate oxides.

After being submitted to chemical reactions, zirconium oxide is obtained, which is a biocompatible ceramic material. Most commonly known as zirconia, it has been used in medicine and orthopedic since 1962 as a replacement for titanium prostheses. However, it was later used in implant dentistry.

Later, in 2000, implants with zirconia abutments were developed, and by 2005 the first fully zirconia implant was created.

Why are zirconia dental implants healthier?

Metal allergies are reactions that some patients can experience when they are treated with metal devices for different scenarios, such as fractures and implants.

During the process of oxidation, the electrons move from the zirconium to the oxygen molecules. Therefore, creating a durable ceramic metal-free material.

Without metal particles, the odds of implant rejection are reduced, becoming a highly biocompatible material for dental implants.

Corrosion, osseointegration, and conductivity


Zirconia can resist corrosion. The oral cavity is a wet environment where metals are prone to corrode. Also, their particles can migrate to adjacent areas. Thereby, zirconia corrosion resistance represents an outstanding feature.

Studies have shown that zirconia dental implants have a high rate of osseointegration. This allows them to remain firmly attached to your bone.

Moreover, zirconia is also a nonconductive material. This means that it does not transmit heat or electrical charges through its surface. Bacteria use electric impulses to help themselves to adhere and stay at teeth surfaces. However, due to the lack of conductivity, bacterial growth occurs at a slower pace within zirconia implants surface.

One-piece design 

Most zirconia dental implants are designed as a singular unit comprising the implant and the abutment where the crown will be cemented. This eliminates the risk of bacterial colonization between both parts that exist in implant systems made of separate components.


Ceramic implants are an excellent solution if you are looking for a tooth replacement treatment with a more holistic approach. Their healthy benefits can guarantee you a comfortable experience while achieving your desired results. Moreover, zirconia’s natural color not only makes it a more healthy alternative but also a more aesthetic one.
