Your dentist has given you the
tools to titrate your Narval™CC.
Titration is the process of adjusting
the appliance to ensure it is as
comfortable as possible while
working effectively to treat your
sleep apnea symptoms.
Before taking your Narval CC home,
we strongly recommend that you
practice changing the connecting
rods while in your dentist’s office.
If you have difficulty doing so, your
dentist can assist you.
Additionally, if you have a condition
that can make it difficult to hold
the small connecting rods (such as
arthritis, carpal tunnel syndrome,
etc.), you may want to have your
dentist change the rods for you to
ensure proper adjustment.
1Hold the appliance so that the rods are perpendicular to the splints. The
mechanism that facilitates titration is the bowtie-shaped end of the rod,
which aligns with the bowtie-shaped cutout of the splints. This is more
visible on the splint that goes on your bottom teeth.

2Since the bowtie-shaped cutout is more visible on the bottom splint, disconnect
this side first. With the base of your thumb at the tip of the rod, push inward
and pull the rod firmly to disconnect the rod from the splint. If you are having any
difficulty, be sure to double check that the two bowtie pieces are fully aligned.
Disconnect both rods completely from the splints.
3Select the appropriate connector using the measuring guide on the other
side of this card. Adjust in 1 mm increments only (for example, from 30 to 29),
as adjusting in larger increments may cause undue discomfort.
• To increase protrusion, use a SHORTER connector
• To decrease protrusion, use a LONGER connector
4To re-engage the connectors, hold the rod perpendicular to the splint and
line up the bowtie end of the rod with the bowtie-shaped cutout on the
splint and simply click it into place. Repeat this step until all rods
are connected.
