release metal ions into your mouth due to corrosion, a process that gnaws away bits of metal from the metal’s surface.
These ions react with other components of your body, leading to sensitivity, inflammation, and, ultimately, autoimmune disease. Increasing the corrosion rate, therefore, increases the chance of developing immunologic or toxic reactions to the metals.
Second, some individuals are very susceptible to these internal electrical currents. Dissimilar metals in your mouth can cause unexplained pain, nerve shocks, ulcerations, and inflammation, and many people also experience a constant metallic or salty taste, or a burning sensation in their mouth.
Moreover, there is the concern that oral galvanism directs electrical currents into brain tissue and can disrupt the natural electrical current in your brain.
New Alternatives to Titanium Implants
In recent years, high-strength ceramic implants have become attractive alternatives to titanium implants, and some current research has focused on the viability of materials such as zirconia (the dioxide of zirconium, a metal close to titanium on the periodic table).
Metal-free zirconia implants have been used in Europe and South America for years, but they have only recently become available in the U.S.
Zirconia implants are highly biocompatible to the human body and exhibit minimum ion release compared to metallic implants.
Studies have shown that the osseointegration of zirconia and titanium implants are very similar, and that zirconia implants have a comparable survival rate, thereby making them an excellent alternative to metal implants.
Moreover, zirconia ceramics have been successfully used in orthopedic surgery to manufacture ball heads for total hip replacements.
Therefore, given that titanium dental implants can induce metal sensitivity, inflammation, autoimmunity, and malignant tumors, while zirconia implants
