The Silensor-sl consists of one transparent or tinted splint for the upper jaw and one for the lower. The lower jaw is either held in a predetermined position or advanced by 2 connectors that are fixed laterally to the splint. The Silensor-sl thus counteracts the narrowing of the respitory tracts. The velocity of the inspired air decreases and so does noise generating vibrations of soft tissues.

With Silensor -sl jaw movements are possible but falling back of the lower jaw is prevented. This makes the Silensor-sl a comfortable and effective appliance for snore management. 

Clinical tests have shown that the advancement of the lower jaw considerably reduces snoring in more than 80% of patients and may reduce the apnea index by up to 50%.
