Titrating The EMA Appliance

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.
