Balance Base Abutment C/ | CAD/CAM suprastructures
Step-by-step: Impressions and
model casting for CAD/CAM restorations
A precise stone model made in the laboratory, which
reproduces the clinical situation exactly, is crucial
for the perfect fit of a CAD/CAM-fabricated implant
suprastructure, even at the first fitting. An absolutely
precise impression of the clinical situation is essential
for this.
Dental practice
First consultation:
Impression for situation model
The first impression is taken using
the PickUp technique via retention
caps. Subsequently, the gingiva
forming components are again
fitted until the second consultation,
e.g. the Ankylos protective cap
narrow.
The impression is handed over
to the laboratory with all the
components used.

This should take place over several consultations and
in close cooperation with the laboratory. To better
illustrate the closely linked working steps between the
practitioner and the dental technician, the procedures
involved both in the dental practice and the laboratory
are depicted here.
Dental laboratory
In the dental laboratory:
Fabrication of the situation model
A situation model is made from
the impression. Depending on
which components are used for
impression taking, analogs (for
retention copings) or implant
analogs (for repositioning posts)
are used.
Balance Base Abutments C/ or
Base Abutments C/ narrow are
located in the analogs.
Individual tray
Based on this model, a customized
tray for the pick-up technique is
manufactured. Adequate space for
the impression material must be
ensured while manufacturing the
tray.
