Retraction Cord Placement
Common Problems
I cannot get the cord into the sulcus, I need a
smaller cord The cord keep on poping out of the sulcus
I followed all the protocol and the cord is inthe sulcus perfectly, why the impression still
do not turn out

Retraction Cord Placement ISOLATION (no saliva and no blood)
Use of a hemostatic agent to controlbleeding (hemodent - aluminum chloride,ViscoStat - ferric sulfate)
Applied steady pressure to push the cord
into sulcus (sometime it may take a fewseconds); do not release the pressure untilthe cord stay in the sulcus
Pressure down gingivally (at angle angleslightly toward the root) and backward.
Keep the area dry until you are ready to pullthe cord out to inject the impression materialinto the sulcus
8/3/2019 10 Isolation and Retraction Cords
http://slidepdf.com/reader/full/10-isolation-and-retraction-cords 47/57
As the cord is placed
subgingivally, the
instrument must be pushed slightly
toward the area
already tucked into
place
If the force of the
instrument is
directed away from
the area previously packed, the cord
already packed will
be pulled out
