MicrO2 is a sleep apnea oral appliance by MicroDental Laboratories.

MicrO2 is made from control-cured PMMA Poly(methyl methacrylate). It promotes that the dental device is adjustable with a single piece lingual free part with no moving pieces.

It is CAD/CAM milled sleep apnea dental device, that is FDA approved.

Instead of utilizing an adjustment system that works with screws or connecting bands of different lengths, the MicrO2 features a pair of upper and lower arches that can be set in differing increments. The mandibular advancement adjustments are made by swapping the arches.

Sleep apnea oral appliances, like the Micro2 by Microdental Laboratories work by a moving the lower jaw forward. These devices, also called Mandibular Advancing Devices (MAD), or Mandibular Advancing Splint (MAS) increase the diameter of the retropharyngeal airway behind the tongue. This reduces snoring and obstructive respiratory events during sleep.

How does the process work?
Usually, a person who believes that he/she has sleep apnea, will present to primary care physician with sleep complaints. A sleep study is usually performed – either a home sleep test, or laboratory sleep study. If the sleep study demonstrates mild or moderate obstructive sleep apnea, the patient may be a candidate for oral appliance therapy like the MicrO2 from Microdental Laboratories. The patient is then sent to a dentist for dental evaluation. If appropriate, the dentist will perform an impression of the patient’s teeth. This impression is sent to the dental laboratory where the oral appliance is created using the patient’s teeth impression.  The sleep apnea dental device is worn during sleep.

Obstructive sleep apnea effects over 5-percent of the adult population, and over 1-percent of children. Untreated sleep apnea is associated with an increase in risk for cardiac events, stroke, mood disorder, and motor vehicle accidents. Sleep apnea oral appliance therapy (OAT) is a primary treatment option for patients with mild to moderate obstructive sleep apnea, as well as for severe sleep apnea in patients that are intolerant to CPAP (Continuous Positive Airway Pressure).

Sleep apnea and snoring dental devices, like the MicrO2, are usually ordered by physicians and dentists.
