PANAVIA Veneer LC - CONSISTENCY & AESTHETICS
NEW FILLERS
PANAVIA™ Veneer LC’s excellent handling is facilitated by the newly developed spherical silica fillers and nanocluster fillers (filler load; 66 wt%, 47 vol%). No sagging or drifting occurs due to the thixotropic properties of the cement. PANAVIA™ Veneer LC provides a controlled application, it stays put where applied but flows well during seating of the veneer(s). Thanks to its consistency and low film thickness (≈ 8 μm), PANAVIA™ Veneer LC produces a thin, evenly distributed cement layer. This contributes to easy seating without interference. In addition the use of only small, spherical fillers (Particle size;
0.05 μm - 8 μm) makes highly aesthetic and smooth margins possible and facilitate easy polishability and gloss durability.
SILICA FILLERS
Newly developed spherical silica fillers in the cement provide that it stays put where applied, but flows well during seating of the veneer. Allowing for easy placement without drifting or sagging. During application across the intaglio surface, the resin cement does not stick to the application tip, a property achieved by the addition of spherical nanocluster fillers to the paste.
These novel filler types
result in an excellent level of
smoothness, gloss retention as
well as easy handling.
VISCOSITY & THIXOTROPY
The viscosity of a cement is important and must be sufficiently low to prevent the prosthesis from fracturing during placement. At the same time, it must not be so fluid that it runs off during the application and seating of the restoration. Because PANAVIA™ Veneer LC contains an optimised filler/resin mix, its viscosity is subject to change under pressure. This phenomenon is known as thixotropy. The paste becomes more fluid under pressure during the placement and positioning of the veneer. When the pressure decreases, the viscosity increases again. Due to the thixotropic property of PANAVIA™ Veneer LC, the paste is easy to dispense and little pressure is needed to position the prosthesis and the excess is easy to remove. In short: maximum control.
Materials with the same viscosity do not necessarily have the same thixotropy. Temperature and pressure affect viscosity. The degree and rate at which a material returns to its original viscosity when the pressure is reduced depends on the thixotropy of the material.
