Description

Vita VM13 Porcelain Base Dentine is a high-fusing feldspar ceramic with a fine structure, designed for porcelain-bonding alloys within the CTE range of 13.8 to 15.2 x 10⁻⁶K⁻¹. The application of fluorescent and opalescent supplementary porcelains allows for extremely individual, aesthetically satisfying results, with further customisation possible using Vita Akzent Plus and Interno stains.

VM13 Porcelain Base Dentine delivers enamel-like refraction and reflection characteristics, along with high firmness and excellent modelling properties. It can be ground and polished exceptionally well, producing homogeneous, dense surfaces that offer high plaque resistance and are antagonist-friendly. Base Dentine forms the foundational dentine layer within the VM13 build-up sequence, supporting very good aesthetic results, further complemented by a comprehensive range of supplementary porcelains for individualisation.
