The Emerald Herbst appliance is a customized oral device featuring both lower and upper trays and interlocking system. The product is non-sterile, biocompatible, and provided in a sealed box with instructions for use. The upper and lower trays are connected by an adjustable hinge allowing the patient to open and close the mouth while wearing the appliance. The Herbst Telescopic Hardware on the side of the device allows the patient to move forward and left and right but not backwards. This freedom of movement is important for comfort and overall success of the device.The Emerald Herbst appliance treats snoring and mild to moderate sleep apnea by guiding the mandible forward during sleep, preventing the tongue and soft tissues of the throat from collapsing into the airway.
A removable intraoral device designed alleviate sleep-disordered breathing conditions (e.g., snoring, obstructive sleep apnoea) by repositioning the lower jaw (mandible), frequently in a downward and forward position, and by elevating the soft palate (soft tissue constituting the back of the roof of the mouth). It works by locking the mandible (e.g., holding the teeth) and preventing it from retruding and by applying pressure to lift a drooping soft palate, thus increasing the patency of the airway and decreasing both air turbulence and airway obstruction. This is a reusable device.
