Fabrication of primary splint
Retention copings matching the
diameter of the abutment are used
for manufacturing the primary
splints, which are attached to the
analogs or the abutments with the
respective screws:
M 1.6 mm occlusal hex fixation
screw, extra long (order no. 3105
6025) for retention copings,
narrow, or wax-up screws (order no.
3104 5211/short and 3104 5213/long)
for 5.5 mm diameter retention
copings. The autopolymer resin
splinting is divided into separate
segments and is sent to the
practice for intraoral splinting and
impression.
Second consultation:
Intraoral splinting of the synthetic
elements
The practitioner attaches the
separate synthetic primary splint
segments delivered from the
laboratory onto the Balance Base
Abutments using the fixation
retaining screws. By doing so,
an adequate gap between the
separate segments should be
ensured. Where there is contact,
grind off the synthetic material.
Then, the tension-free synthetic
segments are splinted intraorally
using the same autopolymer used
by the laboratory.
Splint impression
The impression is then taken on
top of the now splinted retention
copings using impression material
and the customized tray. After the
dental impression material has set,
the fixation screws can be undone
and the entire tray removed.
This high precision impression is
sent to the laboratory to fabricate
the master cast, and on it, the wax-
up.
Dental practice
It is from this second impression of the intraoral splint
that the laboratory fabricates the master cast, and on
it, the wax-up.
