Your implants are almost definitely titanium. Zirconia are very very new (only FDA approved for 5 years in the US) and very few place them yet. Also they are much more expensive, you would know if you had them! The quote I got was 5k per implant. And I have to travel 2-3 hours to find the closest person who does them vs titanium I could get from multiple places right in my town and they are more like 2-3k each. I hope that is helpful info.
