INTRODUCTION
Congratulations, you have taken the rst steps to
improve your sleep and well-being!
Your Healthcare Professional has chosen the
O2Vent Optima™ (Optima) specically for your
snoring and/or obstructive sleep apnoea (OSA)
therapy. OSA is a condition where a suerer
experiences repetitive episodes of partial or
complete blockage of the upper-airway during sleep.
This is caused by obstructions of the nose, soft
palate and tongue.
The Optima is a removable oral appliance that is
tted in the mouth and is intended to reduce or
alleviate snoring and mild to moderate OSA. The
Optima is indicated for use during sleep to aid in the
treatment of these conditions. Intended for adult
patients 18 years or older. The Optima device is for
prescription use only.

HOW YOUR OPTIMA DEVICE WORKS
Provides a unique air channel
in case of nasal congestion
or diculties with breathing
through the nose.
Brings/pulls the lower jaw
forward (this opens the airway
and stabilises the tongue)
The air channel allows the
air to ow smoothly to the
back of the airway.

In general, the Optima works in the following way.

In order manufacture the Optima, an image of the teeth
using 3D scanning or impressions are taken. The information
is sent to a laboratory where your customised Optima
will be made. When the Optima is ready, your Healthcare
Professional will t and assess how well the Optima works to
treat your snoring and/or OSA.

OVENTUS
The Optima consists of the following parts:
• Upper tray (upper teeth)
• Lower tray (lower teeth)
• Connector bands
The upper and lower trays are connected to each other
by the connector bands and will be delivered assembled:
– The bands are used to move the lower jaw (i.e. adjust
the trays) forward or backward.
– In order to adjust the trays to your specic needs,
the bands come in dierent lengths to enable
titration adjustment. There are 9 length size options
ranging from 13-21mm.
– Your new Optima is delivered fully assembled with the
19mm connector band as the recommended starting
titration length for all new users*.
– The shorter the connector band, the further the lower
jaw is moved forward.
– After the initial use, your Healthcare Professional will
help you to nd the right length of connector bands to
receive the best therapy.
HOW YOUR OPTIMA DEVICE WORKS CONTINUED
* In some instances, your Healthcare Professional may recommend a
dierent starting length for your connector bands based on your
jaw anatomy.

The Optima trays should never be worn separately.
Always wear both trays (assembled with the
connector bands) when using the device.
8OVENTUS
INSERTING YOUR OPTIMA
BEFORE YOUR SLEEP PERIOD

2. Make sure your Optima is connected with the bands and
they are the same length on each side.
3. Make sure your Optima is clean.
4. Rinse the Optima and brush your teeth before inserting.
5. Using your thumbs, insert the upper tray and gently
“push” onto the upper teeth; the tray should t snugly.
6. Insert the lower tray, “push” onto the lower teeth; the tray
should t snugly.
REMOVING YOUR OPTIMA
AFTER YOUR SLEEP PERIOD
7. Remove your Optima by gently opening your mouth, lift

FINDING THE RIGHT TITRATION SETTING
• Your Optima will be delivered ready to use, tted with
the 19mm connector bands as the recommended
starting titration for all new users*.
• During the initial phase of using your Optima, you will
work closely with your Healthcare Professional to nd
the correct position. ** It is important that you wear your
Optima each sleep period according to your Healthcare
Professional recommendations**
• Ensure the connector band lengths are the same on
each side.
• The titration may take several weeks or longer to achieve
the best therapy.
• If your Healthcare Professional suggests a shorter or
longer length band, refer to the diagram on page 10 for
length and titration information.
• After your settings have been established, you should
wear your Optima each sleep period.
* In some instances, your Healthcare Professional may recommend
a dierent starting length for your connector bands based on your
jaw anatomy.

USING YOUR OPTIMA CONTINUED
TIPS
• If you are having problems
adapting, try wearing your
Optima while watching TV
or reading. It will help you
to get used to using it.
• It might be helpful for you
to track how much you use
your Optima, this will help
you to get into the habit
of applying your Optima
before your sleep period.
The table below shows the lower jaw positioning range that
can be set by the connector band lengths. This is a guide only.
The recommended starting titration for new users in most
instances is the 19mm connector bands.
NOTE: The shorter the connector band, the further the lower jaw is
advanced. The longer the connector band, the less the lower jaw is advanced.
OPTIMA LOWER JAW POSITIONING RANGE
Titration length range: 13-21mm. The shorter the connector
band length, the further the lower jaw is moved forward

OPTIMA CLEANING INSTRUCTIONS

13
OVENTUS
• Place the antibacterial cleanser and the Optima device
in the water so that they are completely submerged and
leave them to soak, following the recommended time
according to the cleanser packet instructions.
• Remove and rinse both the Optima device and Oventus
tub thoroughly with lukewarm water, including through the
airway entry and exit points, to remove the cleaning agent.
• Dry your device after each cleaning with a clean cloth.
• Return to the Oventus tub to store, with the lid open to
allow the internal airway to dry.
• The Optima may change colour over time, which could
be due to certain foods/liquids. This will not change
the eectiveness of the device. If you use coloured
mouthwash after cleaning your teeth, wait 15 minutes
before inserting your Optima, to avoid discolouration. For
best results, follow these provided cleaning instructions.

OVENTUS
MAINTENANCE
Your Optima should be stored in the Oventus tub provided
as shown, during transport or when not in use.
Keep your device away from sunlight and out of reach of pets
and children.
Once you have determined the band length that optimises
your therapy, you can re-order them in packs of 25. To re-
order the connector bands, ask your Health Professional or
visit www.oventus.com.au
The Optima connector bands have a recommended usage
time frame of one month, as usage can aect the band length
and the titration of your device. The connector bands should
be replaced every month or more frequently if required.
GENERAL WARNINGS AND PRECAUTIONS

16 OVENTUS
REPLACING CONNECTOR BANDS
The connector bands are essential for keeping your Optima
device assembled, with the lower jaw set at the chosen
position eg. with 19mm bands. The connector bands need to
be replaced every month as they may lose elasticity. To identify
when both bands need changing, compare their length against
a new band. If the bands are longer or the holes stretch from
circular to oval, it is time to change both bands.
To remove a connector band from your Optima device,
pull the upper and lower device pieces apart (as shown in
diagram). Peel the band away from the wider end of the “lug”
and o the “lug” point.
To apply a connector band, hook the band over the pointed end
of the “lug” and pull gently to hook over the wider “lug” end.

KEEP A LOG OF YOUR OPTIMA TITRATION
It is recommended that you keep a usage log of your Optima
titration setting for the rst month of wear (recording which
length connector bands you try, to advance your lower jaw).
Your entry may be weekly or daily. It may take several weeks
or longer to achieve the best therapy. Refer to page 10 for
