Finishing the framework
After casting, devest and finish
the framework. Small windows for
checking the fit of the caps are
placed in the occlusal edge of the
caps. These allow the adhesive to
escape easier during later bonding
in the mouth.
Check of stability and fit
The stability of the metal frame-
work is checked by applying
pressure on both sides of the
saddles. These should not bend
under pressure. The finished metal
reinforcement in the model is
checked for a contact-free fit on
the caps. To this purpose, the caps
are placed gently on the stumps
and must not come off when the
framework is removed.
The metal framework is bonded
to the tapered caps directly in
the patient's mouth to provide an
optimal, tension-free prosthetic fit
(passive fit). To this end, the dental
laboratory will make the following
preparations.
Preparations for intraoral bonding
The exterior of the tapered caps
is roughened by abrasive blasting
with aluminum oxide in preparation
for intraoral bonding. The caps
and the framework are sent to the
dental surgeon.
If the Ankylos SynCone abutments
are selected in the dental
laboratory, remove these from
the model using the transfer key
and also send them to the dental
practice.
