Background
Sleep Apnea Syndrome (SAS) is a sleep disorder in which breathing stops during sleep. The most common cause is upper airway obstruction, often ending with loud snoring, body twitching, or arm whipping. Sleep apnea is associated with sleep deficits, daytime sleepiness, fatigue, and bradycardia or arrhythmia and electroencephalographic awakening states.
A common Obstructive Sleep Apnea (OSA) is caused by the relaxation of soft tissue near the throat, which causes obstruction of the upper airway, and a narrowing of the airway that causes sleep Apnea. The solution is that the lower jaw of a patient is limited to a proper front extension position in sleep, and the genioglossus muscle drives the hyoid bone and the tongue body to move forwards, so that the air passage of the glossopharyngeal part is smooth; meanwhile, the tongue body moves forwards, so that the compression of the tongue body on the soft palate and the uvula is reduced or eliminated, the palatopharyngeal airway is also unblocked, and the ventilation is improved.
The upper respiratory tract can be opened by wearing the mandibular advancement appliance, so that the ventilation of the patient can be improved, and the sleep apnea syndrome of the patient can be effectively improved. In the present clinical situation, insufficient wearing compliance of patients is a key factor affecting prognosis. The traditional mandibular advancement appliance has the functions of adjusting and fixing by connecting the connecting rods between the upper jaw and the lower jaw, the protruded connecting parts stimulate the mucous membrane of a patient to a certain extent, and have strong foreign body sensation to cause discomfort of the patient, which often affects the wearing desire of the patient, thereby greatly reducing the treatment effect, and the precision of the appliance is still insufficient in clinical use.
