Intraoral devices to prevent snoring increase the tone of pharyngeal muscles, which prevents them from vibration and the appearance of snoring.
There are several types of intra-oral devices to prevent snoring.
Some intraoral devices (eg, "Extra-ent") by referring vaguely resemble a normal baby pacifier and consist of a cup-shaped petals, regarding language, and fixing rims designed to protect against loss or swallowing mouth. The therapeutic effect of the device is a reflex stimulation of the muscles of the tongue and throat, which increases the tone of the sky, preventing vibration and eliminates snoring. Devicehas the greatest effect in patients without acute obesity, uncomplicated snoring and breathing freely through the nose. The main disadvantage of this device is the possible deterioration of the quality of sleep because of the presence of a foreign body in the mouth.
There are also simulated intraoral devices that shift forward lower jaw, which increases anteroposterior airway size and thus reduces snoring and the severity of obstructive sleep apnea (OSA). These devices made of special heat-labile material which when heated to a set top jaw (Mouthpiece as a boxer), after which the patient closes his mouth with extended lower jaw. Harvesting freezes and re-use secures the extension of the lower jaw forward.
These devices provide a good effect with uncomplicated snoring, mild and moderate forms of OSA, especially in patients with malocclusion (posteriorly displaced mandible). The main disadvantages of simulation devices is their high cost (from 100 to 300 U.S. dollars).
