Step-by-step:
Crown or bridge, cemented
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
Assembling the models in the

edentulous gap with a bridge. The same steps are
performed in the procedure for fabricating a single
crown.
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.
