Implant-supported crowns and bridges on Ankylos
Standard C/ abutments can both be cemented and
screw-retained. The fabrication of the suprastructure
is shown using the example of the restoration of an
edentulous gap with a bridge. The same steps are
performed in the procedure for fabricating a single
crown.
Assembling the models in the
articulator
Assemble the models by means
of assembling the impression
in the articulator as it would be
positioned in the patient’s skull.
Remove mucosa mask
Remove the mucosa mask in order
to have an unobstructed view of
the structure of the crown margins.
Attaching the wax-up copings
Attach suitably sized Ankylos
Standard wax-up copings for
bridges. Depending on the axial
alignment, the wax-up copings for
bridges (grey) without internal ribs
are used. This can have advantages
for the insertion alignment.
Wax-up copings with ribs for
rotational locking (white) are
available for fabricating single
crowns.
Cemented suprastructure
Seal both holes in the wax-up
copings with wax.
Wax up the bridge as usual. The
framework is fabricated and
veneered in accordance with
the current dental method for
metal-ceramic or full-ceramic
suprastructures.
The occlusion is designed
according to the “freedom in
centric” principle. A purely incisal /
cuspid guidance should be aimed
for in lateral movements. Check
the interdental spaces after the
veneering for hygienic capability.
