Silensor Anti-Snoring Device
| |
Snoring is a severe problem because |
| |
- many people suffer from snoring (studies
have shown, that app. 40% of the population in
industrialized countries do snore, with males
aged over 60 years it is even 60%
(1))
- snorers do have a poor sleep
- partners of snorers are disturbed in their
sleep because of the noise
- snorers are often tired and un-concentrated
during the day, what can lead to accidents
- snoring promotes heart and blood circulation
problems
- snoring can be the major symptom for the
obstructive sleep apnea
(see note below re:Respirtory arrest)

When your throat muscles relax in
sleep, and the muscle tone in the neck and pharynx
decreases, so they are less effective in holding your
breathing passages open. The soft sides of the airway
tend to close (pharyngeal space) in, and the air has
to move faster through a smaller space.
This causes vibrations of the soft tissues which generate
the noise of snoring as a higher volume of air must be
inspired at a higher velocity and noisy vibration (snoring)
of soft tissues, such as the velum palatinum (soft palate).

Respiratory arrest
during sleep (sleep apnea): Sleep apnea is, at a
certain level of severity, a serious disease that
may cause not only sleepiness during the day but
also serious vascular diseases.
This form of
respiratory arrest lasts at least 10 seconds,
before the patient resumes breathing in an
explosionlike and noise-generating
event.
Obstructive sleep apnea (OSA) is defined
as a respiratory arrest caused by restriction of
the airways. Hypopnea is a reduction in
respiratory volumes during
sleep. Wearing a Silensor anti snoring device may not have any effect on this condition.

How does the
SILENSOR help? |
| |
Silensor |
| |
|
| |
The SILENSOR makes sure, that night is
quiet and sleep is refreshing. |
| |
- The SILENSOR widens the respiratory tract by
anteriorization (moving forward) of the lower
jaw. The velocity of the inspired air decreases.
- Noise-generating vibrations of soft tissue
(snoring) is decreased or prevented completely
by the SILENSOR.
- SILENSOR is a custom-made device for your
patient.
- The SILENSOR is a comfortable device due to
its filigree design.
- Movement of the lower jaw still is possible
with the SILENSOR.
- The SILENSOR does not inhibit breathing
through the mouth.
- With the SILENSOR no further (appartus-)
noise emerges (as with other devices).
- With the SILENSOR there is no need for
operation/surgery.
|
| |
|
| |
The SILENSOR consists of two transparent
splints, one each for the upper and the lower jaw.
The lower jaw is held in a predetermined position
by 2 connectors that are fixed laterally to the
splint causing the pharyngeal space to open
up. |
| |
|
| |
Clinical tests have shown that the
anteriorization of the lower jaw reduces snoring
at 90% and may reduce the apnea index at up to 50%
(2) (3) (4) (5).

Suitability of the SILENSOR |
| |
The SILENSOR can be expected to be very
successful since in almost all cases the noise
involved in snoring is caused by constriction of
the airways.
Similarly, when breathing through
the nose is difficult or blocked, e.g. by polyps,
the use of the SILENSOR is in no way
precluded.
Because of its compact design the
device does not inhibit breathing through the
mouth. |
| |
Major obesity and/or major alcohol intake
impair the efficacy of the device.
The SILENSOR
cannot be used with edentulous patients and should
only be fixed to a partial denture which has
adequate retention. It is up to the dentist to
assess whether or not residual teeth provide
enough retention. |
