GC Initial IQ – Lustre Pastes: for the press-over technique, but also for all GC Initial metal-ceramic and all-ceramic restorations

“Painting by numbers” with ceramic lustre pastes – for a natural translucency and colour depth

Since the GC Initial IQ – One Body concept was first presented at IDS 2007, the overpressed ceramic systems GC Initial IQ – Press-over-Metal (POM) and Press-over-Zircon (POZ) as well as the 3-dimensional ceramic lustre pastes have become indispensable in many laboratories. The new press-over concept from GC EUROPE, with opalescent effect pellets for metal and zircon frameworks, is not just extremely time-saving in terms of handling, but it is also impressively aesthetic and lifelike in its colour results thanks to the newly designed GC Initial IQ – Lustre Pastes. The two special lustre paste sets for POM and POZ are highly versatile and also compatible with all the GC Initial veneering ceramic systems – giving ceramic restorations a natural translucency and colour depth, whether high or low coefficients of thermal expansion are involved.

Owing to the 3-dimensional fine ceramic particles in the GC Initial IQ – Lustre Pastes, the coloured pastes can be applied in a thicker layer than conventional ceramic stains. The result is an impressive depth of colour and vital light dynamics, but also a structured, individualised surface.

Inexhaustible: diversity in the system – aesthetics achieved with the system

For endless creativity the Body and Effect lustre pastes can not only be combined with the press-over technique; they are also ideal as a substitute for the conventional ceramic stains and glaze materials and for colour corrections and changes to the surface structure for all metal-supported and all-ceramic restorations using the GC Initial system! For instance, the Lustre Pastes for the Press-over-Metal technique can be used with GC Initial MC, LF and PC (high CTE) while the Press-over-Zircon Lustre Pastescan beusedwith GC Initial TI, AL and the new Zr-FS (low CTE). To intensify their colour effect even more, the pastes can also be mixed directly with the conventional GC Initial ceramic stains.

No more complicated layering, just single glazing!

Handling of these pastes is also impressive: owing to their thixotropic properties, these special lustre pastes, like an oil paint, can be easily and precisely applied to the finished restoration using a brush. Thanks to the complete serial numbering of the Effect and Body materials, dental technicians can apply them together, alongside or underneath each other, with uncompromising simplicity as if “painting by numbers”. In addition, their special ceramic material properties make them extremely abrasion-resistant and enable them to bond directly to the stained surface. Another advantage is that the GC Initial IQ – Lustre Pastes are supplied in ready-to-use, user-friendly syringes – in other words, no more contamination or drying out.

The desired surface smoothness of the glazed objects can be achieved either by gently tapping the model or by rippling the restoration. The subsequent final firing is performed at 750° to 810°C for metal supported and all-ceramic restorations. Corrections to the final firing or colour changes can easily be made at any time by a repeated GC Initial IQ glaze firing with the same firing values. In short, with just a single 3-dimensional glaze/final firing, dental technicians can achieve a very natural-looking Vita-Classic tooth colour in less than two minutes!

Two lustre paste ranges for two CTE ranges

The two GC Initial IQ – POM and POZ Lustre Paste ranges, which are compatible with the tried and tested GC Initial metal and all-ceramic systems as well as the new GC Initial IQ – Press-over-Metal and Press-over-Zircon systems, are available in an exclusive “black box”. This contains one Neutral, four Body (A, B, C, D) and seven Effect lustre pastes, thinner, two special brushes and a mixing tray as well as demonstration tools for “painting by numbers”.
