Balance Base Abutment C/ | Bar-supported overdentures

Casting the model after taking the impression with

the Ankylos Balance C/ transfer post

The impressions for suprastructures on Ankylos
Balance Base Abutments C/ are made on the implant
level with Ankylos Balance transfer posts PickUp
(open tray) or repositioning technique with the C/
marking.

The impression and the components used, including
the screws, are handed over to the laboratory. The
components are attached onto Ankylos Balance C/
implant analogs. The model is then fabricated as usual.

Screwing in the Ankylos Balance

Base Abutments

Screw the Ankylos Balance Base
Abutments C/ or Base Abutments
C/ narrow hand-tight into the
implant analogs of the bar model
using the 1.8 mm prosthetic hex
ratchet.

If the impression has been taken
using retention copings, this step
is omitted. In this case, the position
of the abutments is shown by the
analogs (Balance Base Abutment
narrow) or the soldering post
(Balance Base Abutment) located
in the model.

Attaching the gold copings

Fit the Degunorm Ankylos
gold copings for Balance Base
Abutment to the abutments and
attach using a corresponding
screw (see page 46).

Adjusting the bars

Adjust the bars to the spaces
between the gold copings. Keep
gaps between the bar and the gold
copings as narrow as possible.

The bar is manufactured by laser-
welding (page 49) or soldering
(page 50).

Step-by-step: Conventionally

laboratory-fabricated bar restoration (laser-welded)

Bar – laser-welded

Bar – soldered

The Base Abutment must not

be inserted with the 1.0 mm hex

insert as this will damage the

thread.
