Zirconia dental implants are considered safe and biocompatible, with published multi-year survival rates comparable to titanium, though the overall body of long-term (15+ year) research is smaller simply because zirconia implants have been in clinical use for fewer decades.
Key takeaways
- —Zirconia is FDA-cleared and used in dental implants worldwide, not an experimental or unregulated material.
- —Multi-year clinical studies generally show survival rates comparable to titanium over the periods studied.
- —The research gap with titanium is about duration of follow-up, not about safety findings within the years studied.
- —As with titanium, outcomes depend heavily on case selection, surgical technique, and aftercare — not material alone.
What 'less long-term data' actually means
Titanium dental implants have been used clinically since the 1960s; zirconia implants entered more widespread use roughly two to three decades later. This means there's simply less time elapsed to generate 20- and 30-year outcome studies for zirconia — it does not mean existing studies have found safety problems that titanium lacks.
What the existing research does show
Multiple systematic reviews comparing zirconia and titanium implants over 5- to 10-year follow-up periods report broadly similar survival rates, generally in the 90-97% range for both materials in well-selected cases, though zirconia studies are fewer in number than the extensive titanium literature.
Where to focus your own due diligence
Rather than treating 'is zirconia safe' as a yes-or-no question, it's more useful to ask your provider about the specific implant system they use, its individual published track record, and their own placement experience with it — since outcomes vary meaningfully by these factors, for either material.

Frequently asked questions
Has the FDA approved zirconia dental implants?+
Yes, zirconia dental implant systems have received FDA clearance and are legally marketed and used in the United States.
Why don't more dentists offer zirconia implants?+
Adoption has been slower partly due to surgical technique differences (especially for one-piece systems) and a smaller number of training programs and specialists, not due to safety concerns specifically.
