Only SynCone abutments with the same
tapered angle may be used in a prosthesis.
The prerequisite for a successful application of
the SynCone concept is the common direction
of insertion of the SynCone abutments.
Screw-retention of the abutments,
closing the screw channel
Following parallelization, screw
the angled abutments in via the
window using the 1.0 mm hex
laboratory screwdriver.
For straight SynCone abutments
with a 5° tapered angle, the screw
channel hole can be sealed with
the cover screw for SynCone C/ 5°
abutments in the patient's mouth.
For angled abutments, self-curing
thermoplastics are used for this
purpose.
Marking the abutments
SynCone 5° abutments are
grooved at the occlusal margin to
hold these securely in the transfer
key.
To avoid misidentification, further
small grooves can be added
individually to the occlusal margin.
Transfer key
Once the abutments have been
aligned, attached and grooved, a
transfer key is fabricated.
This can be fabricated entirely from
quick-curing synthetic material
and, if necessary, provided with
a metal reinforcement, which is
adapted using synthetic material.
