The Science of e.max Ceramic
e.max restorations use a high strength ceramic material called lithium disilicate. This material has over 10 years of use in the dental industry and has proven to be extremely durable in addition to being beautiful.
In clinical testing, restorations made with e.max lithium disilicate have a 98.2%* survival rate. This is one of the highest rates of restorative survival ever documented.
Favorable Wear Characteristics
In the past, doctors and patients have expressed concerns about how all-ceramic restorations could wear on the natural teeth. e.max restorations have been tested and shown to have very favorable wear** characteristics especially when compared to other materials on the market.
When compared to restorations such as traditional porcelain-fused to metal, e.max restorations have shown to have greater resistance to fracture***.
Tried and True. Over 40 million times.
There are more than 40 million restorations placed around the world using e.max which speaks volumes about the material s quality, longevity and beauty.
Biocompatibility is regarded as a material's quality of being compatible with the biological environment, i.e. the material s ability to interact with living tissues by causing no, or very little biological reactions. A dental material is considered to be biocompatible if its properties and function match the biological environment of the body and do not cause any unwanted reactions. Several studies confirm that e.max lithium disilicate is a biocompatible material.
