with prime means of support.
- Secondary abutment: that supports the primary
abutment in addition to that provides the
support to the bridge.
- Pier abutment: is an isolated or intermediate
abutment where the anterior and posterior
adjacent teeth to it are missing.
- Distal abutment:that is situated distal to the
edentulous area or the last abutment distally.
