Balance Base Abutment C/ | CAD/CAM suprastructures
Step-by-step: Impressions and
model casting for CAD/CAM restorations
Dental laboratory
In the dental laboratory:
Producing the master cast
The laboratory produces the
master cast based on the
impression of the intraorally
splinted retention copings.
This stone model is crucial for
the subsequent precise fit of
the suprastructure.

Wax-up
A wax mock-up with tailored teeth
is made on the master cast.
Preparing the transfer key
A transfer key is again manu-
factured from autopolymer in order
to be able to compare the implant
positions in the master cast with
the clinical situation. This key is
finally splinted in the laboratory.
The wax-up and the transfer key
are sent to the dental practice for
intraoral checking.
