**8. Available products**

Many zirconia implants are commercially available. The most famous products are listed in **Table 1**. Even if all available implants are constituted by Y-TZP, the surface characterization (regarding in particular some parameters such as carbon contamination and phase transfor‐ mation) is far to be the same for all products [45], and few independent data are available on this issue. Contrary to CP titanium, the name "Y-TZP" is often insufficient to characterize the material, and the clinician must pay attention to the details of the selected product.
