I have 3 titanium implants now and have heard that zirconia, brand name CeraRoot, might be a better option because the titanium might cause neurological ill effects. What are your thoughts about which might be better for the patient?
I would recommend the titanium implants. I have one myself. I am not aware of any research that suggests any adverse neurological or other biological effects of titanium on the human body—it is one of the most biocompatible of all materials.
I don’t have a problem with the zirconia implants, but there is much less experience with them, and I don’t know any reason to vary from the time-tested success of titanium implants. Titanium has been used for decades, not only in dental implants but in joint and bone replacements all over the body.
There is a certain appeal to metal-free dental implants because there are some metal sensitivities that cause problems that some people have with certain dental work. But a blanket condemnation of metal in the human body isn’t justified, in my opinion. Remember that there are certain metals, such as iron and zinc, that perform essential functions in our biology and are essential ingredients of our diet.
