About IPS e.max
IPS e.max restorations begin with lithium disilicate glass-ceramic. Lithium disilicate is a material that is unique in its ability to match existing teeth. When lithium disilicate is used to replicate a tooth for restorative purposes, the material can be expertly crafted to imitate the translucency, color, and even light diffusion properties of the patient’s tooth for a superior restoration that is typically indistinguishable from the natural teeth.
IPS e.max Restorations versus PFM Restorations
For many years, dental clients relied upon PFM, or porcelain-fused-to-metal restorations. The PFM restorations were more eye-appealing than the all-metal crowns, partial crowns, and inlays and stronger than the porcelain restorations available. Over the last seven years, PFM use has decreased drastically with the introduction and widespread acceptance of IPS e.max. It is estimated that approximately ten percent of crowns manufactured in the United States are now PFM fabrications, compared to about 65 percent in 2007.
PFM restorations have been found to have many drawbacks. It is not uncommon for the PFM restorations to wear down the opposing teeth. PFM restorations have also been known to separate, with the porcelain breaking off from the structure. In addition to these complications, PFM restorations have been known to become more noticeable over time when issues such as gum recession cause the dark metal edge of the crown to show. While PFM restorations touted the advantages of having greater strength and a better fit than all-ceramic restorations and greater blending ability than metal restorations, IPSe.max restorations are superior to PFM restorations in these areas.
IPS e.max Restorations
Lithium disilicate has been found to wear opposing teeth at a much more acceptable rate than most porcelain or metal restorations. IPS e.max restorations are also monolithic instead of bilayered, which have shown to be superior in restorations. In addition to the visual advantages, lithium disilicate is also less costly than most metals. This means that dental clients and their customers can enjoy the advantages of IPS e.max restorations at a lower cost than most other types of restorations.
