Porcelain-fused-to-metal dental crowns (PFMs) have a metal shell on which is fused a veneer of porcelain in a high heat oven. The metal provides strong compression and tensile strength, and the porcelain gives the crown a white tooth-like appearance, suitable for front teeth restorations. These crowns are often made with a partial veneer that covers only the aspects of the crown that are visible. The remaining surfaces of the crown are bare metal. A variety of metal alloys containing precious metals and base metals can be used. The porcelain can be colour matched to the adjacent teeth.
In addition to being aesthetically pleasing, dental veneers can also serve a functional purpose by protecting the surface of a damaged tooth. In some cases, veneers may replace the need for a dental crown, eliminating the need for more invasive tooth preparation.
IPS Inline POM
IPS InLine PoM is a press-on-metal ceramic. With this material, accurately fitting aesthetic and functional restorations can manufactured in a consistent and reproducible quality. IPS Inline is the latest development in the press-on-metal technique. It is a new leucite ceramic which maximises the shade selection, function and surface structure of the restoration.
