you to create the crown first and then
“split” into a custom abutment and final
crown. In the Step menu, you can see the
steps (underscored in red) that need to
be completed prior to moving on to the
Acquisition phase.
fig. 6: The first step that needs to be
completed is to “Select Scanbody Type.”
We have two options for scanning the
restoration: TiBase and ScanPost. This
Tibase is a method to scan the location,
depth and timing of the implant restora-
tion on a model. The ScanPost is a new
feature of the V4.2 software that allows
you to scan intraorally. The difference
is that the ScanPost is positioned much
higher (above the tissue), allowing you
to verify that the scanbody is accurately
seated on the post.
In this case, the TiBase was used (Scan-
Post was not yet available) intraorally.
This can be done, but care must be taken
to ensure the scanbody is seated correctly.
fig. 7: After choosing the Scanbody Type,
you must designate which implant system
is being used. Most major implant manu-
facturers are present in the V4.2 software.
In this case, we used the AT OS 4.5/5.0
system.
fig. 8: When using the Multilayer
technique for creating abutments, we
must designate both the Veneering
Structure Material (the Crown) and
the Framework Material (the Abutment).
For the Veneering Structure in this
case, Ivoclar Vivadent IPS e.max
CAD was chosen.
