Crowns and Bridges
Damaged teeth that can not be restored with fillings and veneers are restored to their former look with ceramic crowns. The tooth or an abutment on an implant are prepared and a dental technitian fabricates the crown. It can be either all-ceramic, zirconia-ceramic or porcelain-fused-to-metal. They are highly aesthetic, biocompatible and long-lasting. Today's ceramic is softer than before and doesn't damage the oposing teeth when chewing. If the treated tooth is extremely damaged a composite post is placed inside the root to give it strength (core build-up).
Porcelain fused to metal crowns (PFM crowns) have a nearly natural appearance, subject to two limitations: since they have a metal substructure, they require the use of an opaquer under the porcelain, which makes it impossible to re-create the translucency of natural teeth. They can show a dark line at the edge of the crown, next to the gum. Sometimes the line doesn't show when the crown is first placed but shows later, as the gum recedes. They do not have the biocompatibility of the „metal-free“ crowns.
All Porcelain Crown
All Porcelain Crown is a crown that doesn't have a metal substructure under it. They are the closest thing to the ideal enamel replacement that modern dentistry has yet invented and are 100% biocompatible. CAD/CAM technology is used in the process to ensure the perfect fit. A core of either aluminum-oxide or zirconia (Procera) ensures a high strength and ensures natural beauty of the gums.
