Step-by-step: Immediate
restoration with long-term temporary
In case of an existing prosthesis with optimal fit and
occlusion, a patient can be restored immediately with
a temporary prosthesis placed on four interforaminal
implants and SynCone abutments. Therefore, the
prosthesis is prepared by the dental technician prior
to the surgical intervention.
Preparing the prosthesis
The prosthesis to be incorporated
must be ground sufficiently to
avoid imperfections on the caps.
The drilling guide can be used as
an aid here. After wound closure,
an alginate impression of the
inserted abutments can be taken
in order to grind the prosthesis
accordingly after casting the
model.
This procedure is highly
recommended in case of metal-
reinforced prostheses. At the same
time, grinding should be kept to a
bare minimum to avoid excessive
polymerization shrinkage.
The polymerization of the caps needed for attaching
the prosthesis is performed chairside. Then the
prosthesis is finished as a long-term temporary.
Shortening the functional margins
Due to the excellent retention
capacity of the SynCone prosthesis
on the tapered crowns, extended
functional margins can be
shortened to a minimum, thus
achieving optimal wearing comfort
for the patient.
Excess synthetic material on the
prosthesis base as well as on the
cap margins has to be removed.
Fabrication of the final
prosthesis with metal
reinforcement
The resin of the prosthesis
cannot compensate the forces
transfered on the tapered caps
on the long term. Therefore, a
new, metal-reinforced prosthesis
has to be fabricated after three
to six months of immediately-
loaded healing. The procedure
for fabricating this laboratory-
manufactured prosthesis is
described on the following pages.
