Sleep Disordered Breathing (SDB)

Sleep Disordered Breathing is defined as labored respiration during sleep caused by airway obstruction. If you suffer from SBD, as you fall asleep you experience a loss of muscle tone called airway patency. The soft tissues in your airway relax against the tongue, partially cutting off air flow to your lungs. SBD can be severe to the point of complete airway collapse.  Those who suffer from SBD experience breathing difficulty ranging from mild to acute: Snoring, upper airway resistance syndrome (UARS), and obstructive sleep apnea (OSA).  Snoring is always indicative of the development or existence of a sleep breathing disorder. UARS is more common in younger women and is often accompanied by headaches, Gastroesophegeal Reflux (GER), and asthma.   OSA is, as defined by the National Heart,Lung, and Blood Institute, "a breathing disorder characterized by brief interruptions during sleep...repeated periods of no breathing for at least 10 seconds at a time."  These periods are called apenic events and can last longer than one minute.

Your Dentist Can Help.

HOW?

Sleep Disorders Dentistry.

SDD (sleep disorders dentistry) concentrates on reducing respiratory distress (your breathing problems at night) by determining the location and degree of airway obstruction and placing your airway in optimal breathing position to restore its patency. in order to determine the severity of your sleep disordered breathing problem, the dentist will "map" your nasal passages and your oral airway with a quick and painless technique called acoustic reflection technology. ART draws a picture of your nasal passages and oral airway with sound. After pinpointing the location and degree of airway obstruction,  your dentist will treat you with Oral Appliance Therapy.

When "mapping"  your airway the dentist uses two tools : the rhinometer and the pharyngometer.

Rhinometer

The rhinometer test is performed first, in order to check the nasal passages. This tool helps to rule out any obstruction or enlargement in the turbinates as the cause of your sleep disordered breathing problem. If an obstruction or enlargement is discovered, the dentist will refer you to an Ear, Nose and Throat specialist.

Pharyngometer

The pharyngometer is used to "map" the cross- sectional diameter of the oral airway and measure its stability. This allows the dentist to discover existing points of obstruction as well as your optimal breathing position. in addition, the pharyngometer is instrumental in determining your eligibility regarding successful oral appliance therapy.

Oral Appliances

After establishing your optimal breathing position, your dentist will fit you with an oral appliance.  An oral appliance looks like an athletic mouth guard, but much less bulky. Using the testing methods the dentist can place the oral appliance correctly, allowing for maximum airway patency. The oral appliance gently holds your jaw in the right position to maintain proper airway function as you sleep.  Successful treatment is achieved by simply wearing the oral appliance at night.

It is important that you treat your sleep disordered breathing problem as soon as possible.
