SynCone® C/ | Overdenture on tapered crowns
Casting the model after immediate loading
If the prosthesis is fabricated as replacement for
the long-term temporary denture made from the old
prosthesis, after healing of the immediately loaded
implants simplified impression with SynCone caps
is possible directly via the already incorporated
Ankylos SynCone abutments of the patient. The
prerequisite for this, however, is that the SynCone
abutments do not present any divergences or
resulting parallel taper surfaces.
Casting the model
To fabricate the model, insulate the
inner face of the Ankylos tapered
caps for SynCone if necessary,
fill with self-curing liquid plastic
and fit a dowel pin. Then fill the
impression with dental stone.
Check SynCone abutments
After casting the model based
on the alginate impression, the
replicas of the SynCone abutments
are measured with a parallelometer
to ensure a common direction of
insertion.
Here it is to be insured that the
abutments do not display any
divergences or resulting parallel
surfaces. After immediate loading
or simplified impression via the
SynCone caps, the selection and
attachment of the abutments given
on pages 74 – 75 is omitted.
The plastic stumps created during
the fabrication of the model serve
as placeholders for the abutments
in the model.
Please continue directly with the
fabrication of the framework, see
page 76.
Step-by-step:
Model casting
After immediate loading
In the case of divergences
and the resulting parallel
tapered surfaces, a new
impression has to be taken
using Ankylos Balance C/
components according to
the protocol for submerged
healing.
