Balance C | All-ceramic crowns
Step-by-step: All-ceramic crowns
with Ankylos® Cercon® Balance C/
Regardless of whether a prosthetic restoration
on Ankylos Balance Anterior C/ or /X titanium
alloy abutments or on Ankylos Cercon Balance C/
abutments is planned, the patient impression is
Ankylos Cercon Balance C/
The preparation of the cast for
processing the Ankylos Cercon
Balance abutment C/ and the
selection of the abutments is
similar to that described for
Ankylos Balance Anterior C/
(page 24).
For reasons of stability, the
small Ankylos Cercon Balance
C/ abutment must not be
further reduced in the region
of the head.

made with the identical transfer post PickUp (open
tray) or repositioning post with the C/ marking.
Ankylos Balance C/ implant analogs are fixed in these.
Customizing the Ankylos
Cercon Balance C/ abutment
Prior to grinding, block the screw
channel of the large Ankylos
Cercon Balance C/ abutment.
Customize the abutment using
diamond burs. In order to prevent
damage to the abutment, use
only water cooling during this
process. Grinding the abutment
in the Ankylos handle for implant
analogs and abutments allows
easier management and prevents
damage to the cast.
Please always observe the
following guidelines for the
preparation and the manufacturer's
information for the system used for
all-ceramic restorations:
• Grind down the coronal area of
the abutment maximally to the
size of the small Cercon Balance
abutment. Do not prepare the
contact surfaces up to 1 mm
above the taper connection.
• Do not go below a minimum
wall thickness of 0.5 mm when
grinding.
• A marked channel or a step with
an internally rounded edge can
be prepared, if preferred.
• A circular step depth of one milli-
meter is desirable. All transitions
from the axial to the occlusal
or incisal surfaces should be
rounded.
For grinding we recommend using
the ceramic-line diamond grinding
sets by DeguDent GmbH.
