inciseTM recommended materials
To prevent cracking, it is necessary to select a porcelain with a coefficient of thermal expansion (CTE or TEK) matched to the zirconia core.
The porcelain used must have a CTE of (9.8 ± 0.5) x 10-6 K-1.
The following systems have been tested by Renishaw and show adequate bond strength to inciseTM zirconia:
- NobelRondo™
- 3M EPSE Lava™
- GC Initial
inciseTM recommended tools
- Edenta CeraGloss HP (part no. 301HP) diameter 25 mm x 2 mm thick
- Edenta SuperMax (part no. 9007.220HP) 22 mm x 2.5 mm thick
- Edenta 'Keramik Tool Set' (part no. 900.410SO)
- Grit blasting - 50 µm alumina at 5 bar air pressure
Framework preparation
The supplied copings have already been grit blasted in a controlled environment. If modification of a framework is necessary, the above tools should be used at high speed and light pressure, and water is desirable.
Do NOT sterilise the restoration using steam. This may have long term implications for the strength of the material.
Renishaw recommends a range of porcelains and tools that are optimally matched with the characteristics of
