IPS e.max ( Lithium disilicate) has a flexural strength of 500 MPa, many times more durable than other porcelains. The excellent flexural strength and fracture resistance make this material work well in the anterior or posterior. Appropriately used, e.max has a high probability of lasting a long time, resulting in patient satisfaction. It is the unique strength of e.max that allows for conservative dentistry, natural esthetics, and longevity.
The strength of the material allows for restorations to be fabricated as thin as 0.3mm. Being able to create veneers in such a thin dimension allows for a translucent effect similar to natural enamel, making it easier to achieve excellent color-matching results. Because the material is so versatile and comes in a variety of colors and opacities, it can block out dark underlying colors or be purposely designed to allow favorable underlying colors to show through.
Another factor of the durability of e.max is the ability to adjust with a high-speed handpiece with significantly less risk of fracturing the restoration than when doing the same with other types of porcelains. It is also effortlessly polished chair-side should the need to make corrections occur.
