Abstract

Introduction: Zirconia is suggested in many clinical situations due to acceptable biocompatibility,
lower price compared with gold restorations, and better appearance than
traditional metal ceramic restorations. New translucent monolithic zirconia has been
developed to merge strength with improved tooth-colour matching. This work aims to
review relevant articles on new translucent zirconia restorative materials. Methods:
The published articles on translucent zirconia were searched through PubMed, Medline,
Google scholar, and indexed journals using the following keywords: translucent zirconia,
transparent zirconia, and tooth colored zirconia. The most relevant articles were selected
and reviewed. Result: Introduction of translucent zirconia, has brought the advantages
such as less tooth preparation, biological compatibility, high strength, good mechanical
properties, and less antagonist wear. However, the effects of altering material constituents
to increase translucency on properties such as phase transformation and low
temperature degradation may warrant further investigations. Conclusion: Translucent
zirconia can be prescribed in many clinical situations and may provide less complicated
procedures compared with the production of multilayer restorations of opaque zirconia
cores and translucent feldspathic veneers. This may otherwise decrease fabrication time
and defects, improve biological properties, reduce abutment tooth reduction, and result
in less antagonist tooth attrition.
