All-Ceramic Crowns & Bridges
Recents breakthrough in adhesives, combined with the development of stronger porcelain materials, allow us to make crowns & bridges entirely of porcelain which is healthier for your teeth and gums also giving a perfect natural lifelike look.
All-Ceramic crowns are distinguished by their excellent aesthetics. Light is not only reflected, there is also real transparency as seen in natural teeth. This effect makes the all-porcelain crown perfect for use in anterior areas, whereby minor form and alignment corrections are also possible.
A further advantage of the metal-free ceramic crown is the tooth-shaded margin, which need not be placed under the gum line. Thus, the crown margin does not irritate the gingival tissue and prevents gum recession.
Porcelain (ceramic) is an extremely biocompatible material with no allergenic potential. This can be a real advantage to predisposed (allergic) patients.
Progressive development in ceramics brings forth ever stronger materials, such as zirconium ceramic. Therefore, it is now possible to fit metal-free porcelain crowns in the posterior area.
Advantages and disadvantages of metal-free all-ceramic crowns:
Aesthetics and durability are important considerations for all-ceramics. IPS Empress has proven itself for more than 15 years as regards both criteria. The IPS Empress pressed ceramic system satisfies discerning users and patients all over the world. Twenty-five million placed restorations are testimony to the durable true-to-nature effect, long-lasting success and the high quality standard of IPS Empress.
Procera All Ceram combines excellent and profound strength with beautiful esthetics. The material consists of 99.5 percent pure aluminum oxide and is biocompatible, thereby ensuring excellent long-term esthetics. Procera All Ceram is translucent giving the tooth a natural appearance. At the same time Procera All Ceram is excellent for concealing underlying surfaces, such as amalgam and root fillings. This ceram is also customized but still industrially produced, ensuring predictable results. You should try quickly in your mouth with minimal adjustments.
Fillings in Tooth Shades (Composite Fillings)
Gone are the days of silver fillings, which used to look black and leak with time leading to caries again in the same tooth.
The adhesive bond between composites and enamel is achieved through etching and application of primer to the tooth’s surface. In this way, even fragile teeth are strengthened. For almost every tooth shade there is a similarly shaded composite available, almost always allowing perfect aesthetic adaptation of the filling.

Ceramic Inlays (Porcelain Inlays)
Ever more patients express the wish to replace their old amalgam fillings with a biocompatible and durable material. From an aesthetic view, ceramic inlays are regarded as the top of all available alternatives.
Inlays are indirect fillings applied in back teeth (premolars, molars). After removal of the old, defect filling or caries, an impression is made of the cavity (that is the drilled out defect). A filling is then made in the laboratory from gold or ceramic, which fits the cavity with the utmost precision and restores the original form of the tooth. In the second session, the inlay is cemented into place. Large inlays which cover the cusps are referred to as onlays.
In principle, all back teeth (molars and premolars) can be fitted with porcelain inlays. Front teeth (incisors and canines), on the other hand, are treated with composites. Only in cases where the defect (caries or filling) reaches deep under the gum, or where the remaining tooth substance is weak and brittle (for example root-canal-treated teeth), is a crown the better and lasting alternative.
