Dentsply Sirona Ankylos Balance C Laboratory Manual page 37

Do not damage the straining screw when grinding. Make sure that an
adequate wall thickness of minimum 0.5 mm is retained, and make sure
that the abutment height is adequate for cemented suprastructures.
Do not grind the lateral threaded hole any thinner particularly with
screw-retained suprastructures.
Customizing the Ankylos
Regular C/ abutments
Grind the Regular C/ abutment
to adjust it to the individual
situation. The prefabricated taper
surfaces and the index must
not be processed. Grinding the
Ankylos Regular C/ abutment in
the Ankylos handle for abutment
analogs and abutments makes
them easier to handle and prevents
damage to the master cast.
Therefore, make sure to have
placed a Regular C/X implant
analog.
Transfer key
Prepare a transfer key to retrieve
the selected position on the cast
and later on in the mouth over the
customized Ankylos Regular C/
abutments (block out horizontal
grooves).
The transfer key is handed over
to the dental practice together
with the completed prosthetic
restoration.
