SNORING PROBLEMS
Clinical Information Before you prescribe a [ SILENSOR] for your patient, we would like to provide you with some additional information on snoring and obstructive sleep apnoea.
Snoring Studies have shown that approximately 40% of the population of the industrialised countries snore and that this increases to 60% in men above the age of 60. Most of the noises produced by snoring are generated by vibration of areas of the soft tissues. During sleep, there is a natural relaxation of the muscle tone in the neck and pharynx and the normal firmness of the tissues decreases, resulting in the formation of bottlenecks or even complete obstruction of the airways, especially when the patient lies on their back. Due to this narrowing of the pharyngeal space, the required volume of air must be respired at a higher velocity to deliver the same quantity of air. This results in stimulation and vibration of soft tissues, such as the velum palatinum (soft palate) and the uvulum. It has been found that snoring can also be caused by external factors such as corpulence, alcohol or sedatives. A reduction or elimination of any of these may in mild cases be sufficient to remedy the condition.
TREATMENT WITH THE SILENSOR
The Silensor is one of the oral appliances which can be worn at night. Its biggest advantage being that it is non-bulky.
The success of the treatment is largely dependent on the patient's acceptance of the appliance. Obviously, the depth of sleep and comfort of the patient will increase with the reduction in bulk of the appliance.
All these benefits are advantages of the [ SILENSOR].
The SILENSOR makes use of the fact that the pharyngeal space is enlarged when the lower jaw is displaced in an anterior direction.
The SILENSOR consists of two separate formings which fit over the upper and lower tooth arches. The formings are connected by two lateral rotating connectors which gently pull the lower jaw forward. Any further opening of the mouth increase the anterior displacement of the lower jaw. Despite wearing the SILENSOR, movement of the lower jaw is possible.
The SILENSOR has proven highly successful even when breathing through the nose is difficult or blocked, 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 impossible, e.g. by polyps, use of the SILENSOR is in no way precluded.
The SILENSOR cannot be used in the edentulous mouth. Where removable partial dentures are worn and are firmly retained within the mouth the SILENSOR can be used. In other cases, it must be assessed individually whether the standing teeth will provide sufficient retention of the device.
Important: In cases of suspected sleep apnoea the clinician should refer the patient back to their GP for referral to a sleep disorder clinic.
The SILENSOR is contra-indicated in cases of myofacial disfunction, TMJ disorders, arthropathy of the tempromandibular joint, or advanced periodontal condition.
Wearing the Silensor Before the SILENSOR is worn the connectors should always be checked to ensure that they are firmly attached.
Laboratory requirements It is essential that the anatomical portions of the impressions are cast in a hard synthetic stone and allowed to set hard before the impression is turned over to be based. It is only at this stage that a further mix of plaster may be made and the impressions turned over to be based. Important: because this appliance fits over that hard tooth structures, accuracy is essential. Casting impressions in one go by turning them over while still soft will cause the forces of gravity to pull the plaster away from the impression interface and create a distorted model.
