Dr. Azadeh Khajavi invented an all-on-six dental implant made of zirconia instead of titanium. Zirconia implants have cosmetic and biological benefits over traditional titanium implants, as zirconia is naturally white so it blends better with teeth, does not corrode like titanium which can cause gray gums, and is less likely to trigger allergic reactions. Zirconia implants also allow for immediate installation after tooth extraction and faster recovery compared to titanium implants.

2. Introduction
Oral implantologist and master surgeon Dr. Azadeh “Amy”
Khajavi is the inventor of the innovative all-on-six metal-free
dental implant made from zirconia. Over the course of her
career, Dr. Azadeh Khajavi’s pioneering non-metal implants
have become the industry standard for biocompatible dental
implants.

3. While traditional dental implants contain a base of titanium,
metal-free implants are set into the patient’s gums using the
biocompatible material, zirconia. There are cosmetic and
biological benefits to opting for a zirconia implant. Firstly,
zirconia is naturally white and blends better with human
teeth. Titanium can show through thinner gums and cause the
tissue to appear gray. This is not an issue with zirconia
implants.

4. Additionally, the type of long-term corrosion common with
titanium implants does not occur with those made from
zirconia. In some cases, metal implants can trigger allergic
reactions, especially in people with nickel allergies or who are
very sensitive to metals. The procedure for installing zirconia
implants is also less invasive as they can be installed
immediately after tooth extraction. Patients also undergo
more rapid recovery when compared with titanium implants.
