What is an advantage of zirconia implants compared to titanium implants, aside from esthetics?

The primary non-esthetic advantage of zirconia implants over titanium implants is their superior corrosion resistance. Zirconia is a chemically inert ceramic that does not release metal ions, making it ideal for patients with metal allergies or sensitivities. Titanium, while highly biocompatible, can release titanium ions over time, especially in acidic environments or with fluoride exposure, which may contribute to peri-implant inflammation. Titanium actually has superior bending strength and a longer clinical track record. Osseointegration rates for titanium are well-established and comparable or slightly superior. Zirconia implants are generally more expensive.
