Anti Snoring Device (ASD)

Snoring Treatment - Anti Snoring Device (ASD)





Over the past 20 years oral appliance therapy has emerged as an increasingly popular treatment for snoring and mild sleep apnea. Although CPAP (Continuous Positive Airway Pressure) appliance is considered the “Gold standard” and treatment of choice in the treatment of OSA (Obstructive Sleep Apnea) many patients are unwilling or unable to comply. Many patients prefer oral appliances to CPAP in most studies.

Generally oral appliances are effective in the treatment of snoring. Unfortunately treatment outcome with oral appliances cannot be predicted with certainty.

The Anti Snoring Device is made of a specially developed for snoring appliances a blue coloured “dual laminate” plastic material. These appliances are designed to move the lower jawbone forwards and with it the tongue (as the tongue is connected behind the middle of the lower jawbone). This forward movement of the tongue opens the airway space causing a reduction in snoring and sleep apnea. The appliances are most effective in cases where the problem is a retruded tongue position during sleep.

Several different appliances are used, some claiming to cure snoring and sleep apnea. They cannot cure but can prevent or reduce snoring and sleep apnea. They have the common effect of holding the lower jaw forwards during sleep. The oral appliances need to conform to SPECIFIC CRITERIA to be safe and effective. There is no guarantee that oral appliances will be successful for every patient. There is not enough scientific evidence to predict the outcome of the appliance, but it has been shown to substantially reduce snoring and sleep apnea in many cases. They most definitely have a place in the treatment of disruptive snoring and mild to moderate cases of sleep apnea.
