20 BRIDGES
A bridge is made up of two or more restorations that are
connected.
Bridge cases are unique in that they are designed as
individual teeth and milled as one unit.
This chapter assumes familiarity with multiple restoration
cases and other intermediate to advanced topics. Refer to
other chapters for more information.
20.1 Tooth preparation for bridges
Ensure the preparations for the abutment teeth are not
angled in different directions. If one is pointed towards the
lingual and the other towards the buccal, there may be
problems with path of insertion and over-milling.
NOTE
Cantilever and Maryland bridges are not supported.
20.1.1 Designating a bridge
1. On the
Setup
tab select each tooth that is part of the
bridge - the abutment(s) and the pontic(s).
2. Select the restoration type for each tooth.
3. Click Link.
The cursor changes to a chain symbol.
4. Click the mesial and distal teeth of the bridge. After each
end of the bridge is selected, the teeth turn purple.
The teeth are now designated as a bridge.
