Description

Vita VMK Master Opaque Dentine is a feldspar veneering porcelain designed for porcelain-bonding alloys within the conventional CTE range of 13.5 to 15.2 x 10⁻⁶K⁻¹. It is especially suitable for veneering non-precious metal frames, thanks to its firing temperature and carefully balanced chemical and physical properties. Within the VMK Master system, Opaque Dentine bridges the masking layer and the dentine layer, offering additional opacity while contributing to the natural shade build-up of the restoration.

VMK Master Opaque Dentine is an uncompromising material where safety and aesthetics are equally prioritized, delivering highly aesthetic restorations through brilliant, natural colours. It supports classical dentine-incisal layering schemes, and is complemented by a comprehensive range of additional porcelains for further individualization.
