Jul 10, 2017

The EMA oral appliance from Myerson increases airway space by advancing the mandible using interchangeable elastic straps. EMA elastic straps come in **9 different lengths** (see figure A,) and **4 different strengths** (see figure B). The shorter the ema elastic strap, the farther the mandible is advanced (see figure C). **36 different straps** allow for the most effective repositioning with maximum comfort.
