All-Ceramic Restorations
All-ceramic restorations are the most commonly placed restorations in America. But there is still a large amount of confusion as to the options and features of the various materials and styles of crown fabrication. The purpose of this article will be to lay out the basic options available in materials and restoration styles, and I will also touch on some of the best applications for the various restoration categories within all-ceramic restorations.
The goal of any dental restoration is so well stated by Dr. Newton Fahl - “The primary goal of either monolithic or layered restorations is to reintegrate form, function, and esthetics with minimal damage and maximum longevity to the remaining natural dentition. Today’s state-of-the-art technology available in both realms is capable of yielding from above average to excellent esthetic results. The clinical choice between one or the other can depend on several factors that include strength and esthetics and whether restoring the anterior or posterior segments.”

IPS e.max Lithium Disilicate
e.max has become a staple restoration at Burbank Dental Lab. The versatility and durability are matched with outstanding esthetics in both monolithic and layered options. Within the e.max system, there are a variety of opacities and shades. These restorations can be either pressed or CAD Milled restorations.
Special Note
e.max is Ivoclar’s brand name for their “whole” all-ceramic system, including e.max ZirPress (fluorapatite glass-ceramic), e.max ZirCAD (Zirconium ZrO2), e.max Ceram layering porcelain (fluorapatite glass-ceramic), and the most recognized e.max LS2 (Lithium disilicate glass ceramic - LS2). The latter is what most clinicians refer to as e.max.

Zirconia Restorations
Zirconia restorations have swept in throughout all categories of restorations. This includes gold crown replacements that are very strong but not extremely cosmetic as well as both monolithic and layered options that are quite esthetic.
Opacities & Strengths
Opacities can range from very opaque with almost equivalent block out capacity as metal, to very translucent in the range of medium translucency e.max. Be aware that the strength will generally decrease as translucency increases.
