Distraction or compression
Once the rod has been introduced and attached to the
implants, distraction or compression can be carried out.
This is usually performed with two neighbouring
implants with one implant firmly tightened and the
other loose. Distraction is carried out with the spreader
forceps and compression with the compression forceps.
The tip of the instrument is placed on the sleeve of the
implants.
Options
Use one of the following alternative methods when for-
ceps cannot be applied directly to the implants because
the neighbouring implants are too far apart.
a. Additional use of holding forceps for rods
Instead of using the fixation ring, secure the holding for-
ceps next to the dedicated implant and carry out distrac-
tion or compression.
b. Additional use of fixation ring
A fixation ring is placed adjacent to the implant where
compression or distraction is to be performed. The ring
is placed onto the rod using the hexagonal screwdriver
and the holding sleeve. The distraction or compression is
now carried out over the implant and the fixation ring.
The implant must be loose (i.e. not rigidly fixed to the
rod) during this procedure. Remove the fixation ring
after tightening the Nut of the implant.
