Elastomeric Metal-free Sleep Anti-snoring Appliance

Studies conducted at the University of
Kentucky Medical Center Sleep Apnea
Laboratory have shown the Elastomeric Sleep
appliance to be effective in the treatment of
snoring and mild to moderate obstructive
sleep apnea. The material used in this appliance
is normally used for tooth movement
procedures because of its elasticity. In the
sleep appliance it is passive and exerts no
tooth-moving forces. The Elastomeric Sleep
appliance is made of soft silicone in a custominjection process to yield the optimum in
retention and patient comfort. This compares
favorably in terms of comfort to other dental
appliances, as well as the CPAP device commonly
prescribed for sleep apnea patients by
physicians. Not recommended for patients
who brux
NAPA Anti-snoring Appliance (with clasp retention or Metal-free)*

The NAPA appliance has been very effective in
reducing objective and subjective sleep apnea and
snoring. In patients who have had overnight
polysomnographic testing before and after the NAPA,
the average reduction in the apnea index was 77%,
with a range from 49% to 100%.
Snoring in nonobstructive sleep apnea individuals
occurs when the tongue is posteriorly displaced, but
not contacting the posterior pharyngeal wall. This narrows the airway which, due to the Venturi
effect, causes the air to move more rapidly resulting in the vibrations of snoring. Most OSA
patients are loud snorers, but not all snorers have OSA. It is important to screen all snorers for
OSA. No OSA patient should be treated by a dentist without the referral of a physician or sleep
disorder center.

Material Options: Hard acrylic with clasping (standard). Also can be fabricated with
Variflex™, (clasping optional), or Durasoft Metal Free (no clasping).
Aveo Metal-free TSD - Tongue Stabilizing Anti-snoring Device

This unique one size fits all device treats chronic
snoring by repositioning the tongue forward instead
of relying on the mandible. Uses gentle suction –
rather than the aveolar ridge or dentition – to stay
in place. Allows patient to swallow comfortably.
Made of an injection-molded medical grade silicone.
No impression needed.
Ideal for these patient types:
• Edentulous • Complicated dentition
• TMJ indicated • Periodontal problems
• Large tongue • Children
Herbst® Anti-Snoring Sleep Appliance

There is now a large body of evidence showing
the effectiveness of mandibular repositioning
appliances for mild and moderate obstructive
sleep apnea. To give an appliance the best
chance to be successful, it should be retentive,
comfortable to the patient, and adjustable from
its original position. The Herbst Sleep
appliance (whether made of hard acrylic, soft
vinyl material, or Variflex heat-softening acrylic)
is more than adequately retentive. Herbst appliances have been used in orthodontics for decades and are well tolerated. The mandibular portion of the appliance can be adjusted forward in 1/4mm increments using telescopic hardware. This allows gradual advancement without the use of shims and allows the clinician a more precise means of positioning the mandible to the therapeutic position. Pre-cut tubing segments of the Herbst hardware can also be used which allows 1mm advancements.
