This report demonstrated the successful clinical use of a modified root-analogue zirconia dental implants for immediate single tooth replacement.
A right maxillary premolar was removed and a custom-made, root-analogue, roughened zirconia implant with macro-retentions in the interdental space was fabricated and placed into the extraction socket 4 days later. Four months after root implantation a composite crown was cemented. No complications occurred during the healing period. An excellent esthetic and functional result was achieved with the composite crown. No clinically noticeable bone resorption or soft-tissue recession was observed at 26 months follow up.
Significant modifications such as macro-retentions seem to indicate that primary stability and excellent osseointegration of immediate root-analogue zirconia implants can be achieved, while preventing unesthetic bone resorption. The macro-retentions must be limited to the interdental space to avoid fracture of the thin buccal cortex. This successful case warrants further clinical research in well controlled trials.
Immediate, non-submerged, root-analogue zirconia implant in single tooth replacement.

Zirconia dental implants are
Mon, 03/16/2009 - 07:09 — Dr. Jugue (not verified)Zirconia dental implants are more stetics than titanium implants and better for the soft tissues, we must study the case before implant this kind of implant because the one piece implants have risk about osteintegration, there are two serius trademark who work this zirconia implants; Z- Lock & Bredent Medical, being the second the best option in my opinion.
