E Max Crowns in Dentistry

Introduction: In the recent era, the demand for esthetics has seen steep growth. The patients have been highly demanding of newer, more esthetically pleasing restoration for their teeth. This led to the development of ceramic restorations for direct and indirect use. Materials with high strength ceramic core have been developed, where the core is a high strength ceramic material. IPS E-Max is one such development which has been produced by Ivoclar Vivadent, Schaan in Liechtenstein. Aim of Work: This review gives a detailed explanation of the microstructure, mechanical and optical properties of E-Max crowns. It explains the various clinical indications of E-max crowns and their performance. Methodology: This review is a comprehensive research of PUBMED and Google Scholar from the year 1990 to 2019. Conclusion: E-Max crowns have gained huge popularity in recent times because they combine the excellent esthetics and superior mechanical properties of all-ceramic and metal-ceramic restorations. The mechanical and optical properties of E-Max crowns are largely affected by the microstructure of the material, and hence a detailed study of the microstructure and phase transformation of the material is required. Due to the recent developments that keep taking place in E-max crowns and the recent advent of the material, there is a shortage of long-span studies for E-Max crowns, and hence more studies should be carried out to study the longevity and long term clinical success of E-Max crowns.
