3. Supreme intelligence and a fast bur
First it’s chalky, then
it’s hot, then it’s hard

4. cercon base cercon ceram KISS
It can do everything
The extra class:
Cercon is an all-round material.
The high-performace ceramic, ziconium
oxide has already been in use for along
time - in diverse applications such as the
Space Shuttle, Porsche cars

11. Standard Prep
• preparation:
120–140°
• 6° taper

12. Marginal Prep
•Shoulder or Chamfer Preparation
•1 mm circumferential shoulder

13. Prep
Standard Procedure,
line angles must be
softened

14. Sharp, clear impressions
are a must !!
A reliable bite is needed !!
Stable dies are required !

18. Confirm that preps have a parallel path of
insertion

19. Always use the surveyer....never
“eyeball it“

20. Standard waxing procedure
Wax the copings 0.5mm
thick
Add
the pontic,
connectors at
least
3x3mm

21. To control the right fitting of the modellation in the
scanning frame use the scanning pattern

22. Inserting the scanning frame into the parallelometerRemove all unnecessary parts off the modelLower scanning frame over the wax modellationSetting wax sticksFix the wax modellation to the scanning frameRemove modellation from the model

23. Cover the wax up with scan powder

25. operating instruction Cercon brain / CAM
Scanning and milling time:
Cercon base12 30 min
Cercon base30 50 min
Cercon base38 65 min
Cercon base47 90min
• course mill:
2,8 mm Ø
• fine mill:
1,0 mm Ø

27. separating the frame work
• the not sintered
material shows a
chalky consistence
• first the frame-
work has to be
separated from
the frame
• therefore sandblasting with
50 µm Al2O3 with 1 bar
pressure has to be applied
onto the gates

30. Product presentation
This and more is possible with CAD
More rapid digitization
More rapid modeling
Adjustable cement gap
Faster and better milling
(new strategy)
More economical use of

35. Cercon heat

36. Units are place in the Cercon Heat. The
temperature goes up to 13500
C and holds
for 2 hours.
• Put the crown or the framework
with the occlusal side on the
furnace tile.
• Push the start button and the
sintering process begins.
• After 6.5 hours the shrinking
process is done.

38. Influence of Sintering on the Microstructure
as milled as sintered

39. Always use water-cooled turbines for
grinding the sintered frameworks

40. Fit the frame work

41. The framework should be sandblasted with
110 µm Al2O3 and a pressure of 2,5 bar
carefully except for the margins and cleaned
with steam water

42. Veneering with Cercon Ceram KISS

43. Kiss: five advantages !
- optimum shade harmony
- easy and fast processing
- only 73 powders for all solutions
- efficient full-assortment
- extrem reliable

44. Economic efficiency :
• Reduced assortment.
• paste opaque or powder opaque
availible
• Fast firing cycles due to higher
heating rate.
• No long term cooling in combination
with concept alloys.
• Time saving during layering due to
the 3 powders layering technique.
• Low investment for the Lab due to
the small assortment and
good reasons for using Kiss

45. Minimum costs – maximum aesthetics.
