|Ceramics have been widely used in dentistry and as the demand for more aesthetic, and stronger prostheses increase, ceramics have been developed, that give increased mechanical properties as well as superior aesthetics. One of the most widely used ceramics in dentistry are the glass ceramics group of dental ceramics. Glass ceramics were first developed by Corning Glass Works in the late 1950s. Over time, manufacturers started adding filler particles to the base glass composition to improve mechanical properties, such as strength and thermal expansion and contraction behavior. In order to be able to extend the use of resin-bonded ceramic restorations and possibly use them for bridge construction, a glass ceramic based on a SiO2–Li2O (lithium disilicate) system has been developed and introduced into the market in 1998 (Empress II, Ivoclar- Vivadent). IPS E.max (Ivoclar Vivadent) was introduced in 2005 as an improved ceramic material compared to IPS Empress II. It consists of a lithium-disilicate pressed glass ceramic, but its physical properties and translucency are improved through a different firing process. E.max which has been widely adopted as the ceramic of choice by many clinicians and this lecture will focus on its background, uses and also the clinical applications and limitations of this material, to ensure a long-lasting, well researched applications of this dental ceramic in the clinical setting.|
