Abstract

The invention provides an adjustable mandibular advancement device used for treating benign sleep apnea syndromes, mild-moderate obstructive sleep apnea hypopnea syndromes and sleep apnea syndromes. The adjustable mandibular advancement device comprises an upper tooth socket and a lower tooth socket, a first connecting block is arranged on the lower surface of the upper tooth socket, a second connecting block is arranged on the upper surface of the lower tooth socket, and the first connecting block and the second connecting block are connected through connecting shafts. One end of each connecting shaft is connected with one connecting block through meshed thread structures, and the other end of the same is connected to the other connecting block. By the adjustable mandibular advancement device, accurate mandibular advancement amount is provided according to actual requirements of a user, so that the 'sleep apnea syndromes' is treated more effectively.

Description

technical field [0001] The invention relates to a device for treating benign snoring and mild to moderate sleep apnea-hypopnea syndrome, in particular to an adjustable mandibular advancement appliance. Background technique [0002] Snoring is a very common sleep phenomenon. According to its severity, it can be divided into benign snoring and sleep-disordered breathing syndrome. Sleep structure disorder, and induce high blood pressure, arrhythmia, myocardial infarction, angina pectoris, and even nocturnal apnea for more than 120 seconds, can easily lead to sudden death. At present, the methods of operation and drug therapy are commonly used for treatment, and the cost of operation is high, while drug therapy has a long course of treatment and slow effect. [0003] Oral appliances (also known as mandibular advancement devices, snoring devices, etc.) have been used clinically to treat snoring for many years. Generally, oral appliances include upper teeth brackets and lower tee...
