The document discusses dental biostratification using Ceramic Dentin. Ceramic Dentin consists of three main components: Dentin, Dentin+, and Transpa. When combined, they recreate the optical properties and three-dimensional structure of natural dentin layers, resulting in a highly natural appearance. The biostratification technique allows for individual customization of each dental restoration with uniform and seamless transitions between the different ceramic layers. This sophisticated ceramic system provides professionals with a versatile solution for reconstructing the anatomical and optical complexity of natural teeth.
