The new IPS d.SIGN porcelain is a milestone in the evolution of the metal-ceramic technology. This ceramic closely simulates the optical characteristics of natural tooth structure while providing maximum strength and durability. IPS d.SIGN ceramic comes closer to mimicking all of the properties of natural teeth than any other dental material to date.
IPS d.SIGN ceramic exhibits wear characteristics more comparable to natural enamel than other feldspathic ceramics. It will not aggressively wear opposing natural dentition.

The brilliance achieved with d.SIGN ceramic material is the result of its unique refractive index. The fluorapatite crystals scatter light within the ceramic in a way similar to that of hydroxyapatite crystals found in natural tooth structure. Its physical properties are stronger and more durable than the typical feldspathic porcelains.

Revolutionary Material

IPS d.Sign is a revolutionary new glass-ceramic-fused-to-metal system featuring a patented new "Fluorapatite-Leucite Glass-Ceramic" with matching alloys. This patented formula is unlike any feldspathic porcelain ever produced because it replicates the shape of the needle-like hydroxy-apatite crystal found in natural tooth structure.
