FEM ANALYSIS FOR STRESS DISTRIBUTION OF ROOT ANALOGUE ZIRCONIA DENTAL IMPLANT: A REVIEW

Abstract

Dental implants constitute a well-established approach for substitute of lost teeth with titanium being the most preferential material for implantation. However, titanium has its confines in esthetically demanding cases and neither the form nor material of such implants has changed much over the past 40 years. Immediate implantation is used 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 has 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 toot. No complications occurred during the healing period. An excellent aesthetic and functional result was achieved with the composite crown. Significant modifications such as macro retentions seem to indicate that primary stability and excellent osseointegration of immediate root-analogue Zirconia implants can be achieved. The macro-retentions must be limited to the interdental space to avoid fracture of the thin buccal cortex.
