Dental implants constitute a well-established approach for replacement of lost teeth with titanium being the most
favored material for implantation. However, titanium has its limitations in esthetically demanding cases and neither
the form nor material of such implants has changed much over the past 40 years. Immediate implantation has been
introduced to overcome the disadvantages of conventional implantation which in turn has many disadvantages
owing to the incongruence of the implant to the extraction socket. Today, there is scientific evidence that zirconia dental implants osseointegrate well and offer many advantages over titanium implants. The successful use of
zirconia ceramics in orthopedic surgery led to a demand for dental zirconium-based implant systems. Because
of its excellent biomechanical characteristics, biocompatibility, and bright tooth-like color, zirconia (zirconium
dioxide, ZrO2) has the potential to become a substitute for titanium as dental implant material. In addition, there
are previous reports on the successful use of Zirconia as root-analogue implants by reproducing the contours of the
extracted tooth.
This article presents an overview of the technique of using root analogue zirconia dental implants as an immediate
implantation material which are replicas of the extracted tooth and therefore truly anatomical and socket friendly.
