SynCone® C/ | Overdenture on tapered crowns
After intraoral bonding of the tapered caps and the
metal framework, the dentist is to perform a bite
registration and produce an overall impression for
transferring the framework position in the patient’s
mouth. Both are sent to the dental laboratory together
with the metal framework bonded to the caps.
The SynCone abutments always remain in the patient’s
mouth. The existing prosthesis should be ground out
in the area of the abutments now remaining in the
patient’s mouth and adapted to the altered situation
using non-hardening relining material.
Casting the model
The dental laboratory creates a
model from the overall impression
sent by the dental practice,
showing the exact position of
the intraorally bonded metal
framework in the patient’s mouth.
To fabricate the model, first
insulate the Ankylos SynCone caps,
fill these with self-curing liquid
plastic and provide with a dowel
pin. Then fill the impression with
dental stone.
Dividing the tray
The tray must not be removed as
usual after the stone has hardened,
as this may cause the framework
to bend. Instead, the synthetic tray
is divided into segments and the
impression is removed from the
model and framework in sections.
Opaquing the framework
Pink opaquer is applied to the
framework to complete the
prosthesis.
