I N T R O D U C T I O N
Creation CP L & M is an injection moulded ceramic for fabricating
inlays, onlays, veneers and single crowns using the staining as well
as the build-up technique. A further indication is the „Metal Overpress“
technique. This technique opens a new dimension both
economically and aesthetically. Its physical properties, aesthetics
and unique shade stability are impressive.

I N T R O D U C T I O N
BUILD-UP TECHNIQUE
Inlays, onlays, veneers and single crowns can be fabricated efficiently
and aesthetically using this technique. Units are waxed-up
to their final shape on conventional section models and then injected
using the appropriate translucent pellet. After the injectionmoulded
units have been prepared, Creation CC.LF. Make Up
Instant stains are used to add the finishing touches.
STAINING TECHNIQUE
This technique is used for restorations which require high-quality
aesthetics. Fully anatomically waxed-up units can be injectedmoulded
and then reduced, or units can be waxed-up in reduced
form and injected using appropriate pellet. Creation LF and Creation
CC.LF. Make Up Instant stains are used for facing (The stain can
be mixed in or used on the surface). The dental technician’s creativity
is unlimited using this combination of materials.

Inner walls should not be prepared parallel, but open out approx.
15 ° towards the occlusal surface. Occlusal preparations
should be approx. 2 mm deep. Box preparations should have
rounded corners and edges with no contact to the opposing bite
at the junction of the tooth and inlay and no feather edges.
CROWNS
Reduce the incisal edge by 2 mm and labial and buccal walls by
1 – 1,5 mm. Prepare a well-formed deep chamfer or 90° shoulder.
There should be no sharp edges and a minimum space of 1 mm
palatally.
L A M I N AT E V E N E E R S
Prepare labially to a minimum of 0,5 mm at the gingival deep
chamfer and up to 1 mm at the incisal edge. All preparation margins
should be deep chamfers.

Push the silicone ring on the crucible former. Fill to just below
the edge of the silikon ring with special investment for injection
moulded ceramics. Put on the mould base former turning gently
(investment should exude easily through the opening). After the
investment has set, turn the mould base former and mould former
carefully to remove them. Smooth the underside with a plaster
knife. Follow the directions for preheating in the instructions for
use for the investment.
Important: Do not preheat the pellets!
Preheat the aluminium plunger!
Do not preheat the one-way plunger!

DEVESTING
11 | LOW & M E TA L
Mark the length of the plunger on the mould and separate along
the length of the mark. Then carefully break apart the sections of
the mould. The pressings should be roughly blasted with glass
beads (50 μm) at 4 bars with a pen blaster, then carefully with glass
beads (50 μm) at 2 bars.
Do not use aluminium oxide for blasting!

F I N I S H I N G
12 | L O W
Carefully remove the sprue pins with a suitable cut-off disc.
Now fit the pressed parts onto the die and then depending on
the technique used - carry out the finishing.
BUILD-UP TECHNIQUE
The fully anatomically modelled restoration should be reduced
with finishing abrasives that are suitable for working porcelain or
if the restoration was reduced before wax-up, prepare it for veneering.
Before layering, the surface should be blasted with aluminium
oxide (50 μm) and very slight pressure (1bar). Layering can be
started after through cleaning (steam blaster/ultrasonic cleaner).
Minimum framework thickness 0,8 mm or rather 2/3 of the anatomical
form must consist of pressable ceramic!

STAINING TECHNIQUE
13 | L O W
The objects are ready-finished (contact points, surface texture
etc.). When using silicone rubber polisher, blasting with aluminium
oxide (50 μm) and slight pressure (1bar) are required. Any
corrections can still be made with the Creation LF layering porcelain
before staining. Individual characterisation is then done with the
Creation CC.LF. Make Up Instant stains. One or more stain firings
may be carried out, depending on the situation. Then glaze the
ready-stained restoration once or twice.

B U I L D - U P
14 | L O W
Layering with Creation LF. Before layering, a characterisation
firing with Creation CC.LF. Make Up Instant stains can be fixed.
Missing areas of dentine can be added using dentine porcelain.
The incisal parts are added to the anatomical form, then fired as
specified in the firing chart. Firing is performed on firing cotton
or thin metal firing pins (use platinfoil), but molars should only
be fired on firing pad. A correction firing can be carried out, if
necessary.
A minimum thickness of 0,8 mm must be observed or 2/3 of the
anatomical form must consist of pressable ceramic!

G L A Z E F I R I N G

CEMENTING ALL-CERAMIC PRESSED CROWNS
The restoration fabricated from Creation CP Low has to be
adhesively cemented!
18 | L O W
Pre-treatment of the restoration before bonding (please follow
the manufacturer’s instructions):
• Carefully sandblast the inside of the crowns with Al 2O 3 (50 μm)
and 1 bar of pressure.
• Sandblasted surface.
• Etch the roughened surface with maximum 10 % hydrofluoric
acid for two minutes, according to the manufacturer’s
instructions.
• Thoroughly remove the acid residues under running water.
Then clean with ultrasound or steam blaster. In the dry state,
a milky white surface (fluorosilicate crystals) is visible.
• Acidify the fluorosilicate crystals with phosphoric acid (39%)
for one minute. Then thoroughly clean under running water.
• The microretentive surface is ready for adhesive bonding.

PRESS OVER METAL
The press over metal technique combines in an unique way
economic efficiency and aesthetics. This technique offers unlimited
possibilities to the technician, perfect ceramic shoulders
for crowns as well as for bridges. „Press over metal“ combines
the benefits of a metal ceramic with the possibilities of press
ceramics.
· Cut back technique: For highly aesthetic restorations.
· Cut back easy technique: Efficient and even aesthetical with
perfect accordance to the Vita ® Classic shade guide.
· Staining posteriors: Easy, fast and beautiful.

ALLOY
Overpress technique: Alloys with a coefficient thermal expansion
between 13,8 – 14,2 (25 ° – 500 °C) can be used.
This information is not obligatory. Please check the alloys suitabilities
for the press over technique before you start using it.
WAXING-UP
It is recommended to produce a diagnostic wax-up to position
the framework pattern correctly. You wax-up a little reduced as
with the MC technique with full shoulder. The pattern should
correspond to the reduced tooth mould to guarantee constant
layer thickness. The later metal part should be kept as small as
possible to avoid tension with the press ceramics.

WAXING-UP
The model is isolated and then the framework is put on the model
without pressure. According to the technique used you can
either wax-up completely or reduce. The minimum thickness of
the restoration is 0,8 mm.
Important: Check internally for wax, keeping wax free!
SPRUEING
The objekt is sprued directly. The wax wire should be 3 mm in
diameter, 5 – 7 mm long and should not taper towards the pattern.
The pattern is waxed onto the crucible former in a central
position.
