IPS Empress Overview

IPS Empress is the original pressed all-ceramic, and has been successfully used in clinical situations for the past 10 years. During this time, IPS Empres®s has continued develop and refine this product to satisfy the changing customer and market requirements. With no metal substructure or core material, the light refraction and reflection of IPS Empress® more closely mimics that of natural tooth structure. Testing shows that the wear characteristics of this ceramic are in the range of natural enamel. IPS Empress® pressed reinforced ceramics exhibit nearly two times the strength of conventional porcelains helping ensure long-term esthetics and durability.

The many indications of the material range from veneers to all-ceramic bridges. The system is rounded off by matching cementation materials.

IPS Empress Preparation

Facial Enamel Reduction
0.6 mm depth cuts are made to establish a uniform preparation and porcelain
Uniform Facial Preparation
A medium grit rounded diamond bur is used to remove a uniform thickness of facial enamel by joining the depth-cut groves

Uniform Facial Preparation
The depth of the grooves are joined in three planes by angling the diamond bur to the corresponding gingival, middle, or incisal plane of the tooth.

Chamfer Margins
Correct preparation of the chamfer margins interproximally allow the appropriate bulk of porcelain.
Interproximal Extention
Using the same diamond bur, the interproximal preparation is extended from the gingival chamfer into the proximal space.
Incisal Preparation
The diamond bur is angled to bevel back the incisal edge.
Linqual Reduction to Increase Length
The diamond bur is angled to eliminate undercuts and establish a deep chamfer on the lingual aspect of the preparation to ensure a passive fit. The incisal should be rounded. Avoid sharp line angles.
