SynCone® C/ | Overdenture on tapered crowns
Step-by-step:
Fabrication of the metal framework
Regardless of whether the prosthesis is fabricated
following submerged healing or after immediate
loading on Ankylos SynCone abutments already in situ
in the patient's mouth, all further steps for fabricating
the framework and finishing the prosthesis are
identical.
Attaching Ankylos tapered caps
for SynCone
Place the Degulor tapered
caps without retention on the
abutments and cover with a
0.2 mm thick layer of wax as a
placeholder.
When using tapered caps with
retention, the retention section
of the caps should be ground off
beforehand.
All undercut sections should be
blocked for preparation of the
duplicate model for making the
cast.

Wax-up of metal framework
The metal reinforcement, repre-
sented in the illustration as an
internal reinforcement, is waxed up
on the investment model. A wax-
up with matrix ensures the correct
position of the metal framework, a
rear cover plate can be fabricated
as an option.
Ensure that the connections
between the cap mountings and
the retentions are stable. The
framework must have a clearance
of 1–2 mm to the basal mucosa and
should be shorter than the caps.
