The EMA Oral Appliance works by opening the bite and advancing the lower jaw with interchangeable elastic straps to increase airway space. The EMA is made from a thermoplastic polymer that delivers superior impact strength to acrylic at a lower cost than polycarbonate. The flexibility of the elastic bands allow for individualization of treatment, and the ability for quick and easy adjustments. Bands of varying elasticity move the mandible forward into the desired position while allowing the jaw to move in all directions. This positioning of the mandible causes a forward movement of the tongue, reopening the air flow through the oral pharynx. EMA elastic straps come in 9 different lengths and 4 different strengths. The shorter the ema elastic strap, the farther the mandible is advanced. 36 different straps allow for effective repositioning with maximum comfort.
