Oravan Herbst is intended to reduce snoring and mild to moderate sleep apnea in adults.

The Oravan Herbst is intended to reduce snoring and mild to moderate sleep apnea in adults. It is made of orthodontic acrylic trays and herbst assembly. It has two acrylic pieces - the upper acrylic tray that fits over the top posterior teeth and the lower acrylic tray that fits over the bottom posterior teeth. The herbst assembly provides a standard titration mechanism and enables mandibular advancement. With this design, the Oravan Herbst allows the physician to increase the patient's pharyngeal opening, improving their ability to exchange air during sleep and reduce vibrations. Each Oravan Herbst device is patient-specific (customized for each patient).
