Problem
Snoring is a severe problem because
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 unconcentrated 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
Snoring is generated when soft tissue vibrates. During sleep, muscle tone in the neck and pharynx decreases. This causes narrowing of the pharyngeal space, the required volume of air must be inspired at a higher velocity and noisy vibration (snoring) of soft tissues, such as the velum palatinum (soft palate) and the uvulum is stimulated.
OSA (without Silensor)
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.
The severness of this sickness is assessed by an apnea-index.
A index up to 5 is seen as normal, 6-20 as medium and above as severe sleep apnea.
The index is to be determined in a sleep laboratory.

recreativ sleep (with Silensor)
How does the Silensor help?
Erkodent´s Silensor, an individual solution for the patient, makes sure that night is quiet and sleep is refreshing.
The Silensor consists of two 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.
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.

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).
In which cases the Silensor is suitable?
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.
