Balance Base Abutment C/ | Bar-supported overdentures
For the fabrication of soldered bars, it is necessary
to produce a soldering model for attaching the bar
during soldering. Ankylos soldering posts (for Balance
Base Abutment) or analogs (for the Base Abutment
narrow) are used in the soldering model.
Bar – soldered:
Attaching the bars for soldering
Abrade the gold copings in situ
to obtain a better bond when
attaching the bar copings to the
bars using modeling compound.
Check the hygienic capability of
the construction.
Oxidizing the soldering posts
(analogs)
Oxidize soldering posts or analogs
by flame.
Screw-retaining soldering posts
(analogs)
Detach the bar construction
from the model and screw the
soldering posts onto the structure
using wax-up screws (order no.
3104 5211/short and 3104 5213/long).
Analogs are used for restorations
on Balance Base Abutment C/
narrow, to which the construction
is screwed using M 1.6 mm occlusal
hex fixation screws (order no.
3105 6022/24/25/26). The fixation
screws for later use in the mouth
must not be used for the soldering.
Step-by-step: Conventionally
laboratory-fabricated bar restoration (soldered)
Bar – soldered
A passive, tension-free fit should be ensured when
manufacturing bar constructions as otherwise, problems
such as loosening or fracture of the screws may arise after
the prosthesis has been worn for a certain period.
