Description

Vita VM9 Effect Opal is a refractory feldspar ceramic with a fine structure, precisely matched in CTE to ZrO₂ frameworks (approximately 10.5 x 10⁻⁶K⁻¹), ensuring an optimum bond. It is also suitable for restorations made of Vitablocs and PM9, and can be individually customised using Vita Akzent Plus and Interno stains. Classified as a Class IIa medical device, Vita VM9 Effect Opal offers dental laboratories a reliable, high-performance ceramic material for creating opalescent light effects, replicating the natural translucency seen in incisal areas of teeth.

This ceramic delivers a natural shade effect and light dynamics, supported by optimal physical properties thanks to its fine structure. An excellent bond ensures reliable results and long-term success, while minimal shrinkage behaviour helps reduce complications during ceramic firing. Excellent modelling properties allow for fast, targeted application of the ceramic, and outstanding grinding and polishing properties support a smooth, refined finish. Homogeneous, closed surfaces offer high plaque resistance, and an extensive range of add-on materials enables excellent light-optical effects for natural, aesthetic results.
