Prof. Dr. Georgios Romanos: "The results of this study confirm wear from metallic, but not ceramic, dental implants at the time of insertion"

As part of the in vitro study conducted by Prof. Dr Georgios Romanos and colleagues on the wear of metallic and ceramic dental implants, five implant groups (groups 1-4 contained titanium implants and group 5 (zirconia implants Zeramex XT) were analysed using XRF spectrometry and statistical, descriptive analyses of Ti and Zr concentrations in the coronal, middle and apical bone interface were performed.

A comparative analysis confirmed differences between the surface stability of the implant and Ti accumulation at the insertion sites of the bone block. There was a direct correlation between the implant length and the amount of titanium found on the bone block. Titanium is released from the implant surface at the time of insertion.

Conclusion: The results of the study confirm the wear of metallic (titanium implants) but not ceramic implants such as Zeramex XT at the time of insertion.
