Since the time of Dr Edward Angle, 100 years of research published in thousands of articles has proven that tongue position and function, plus mode of breathing and mouth breathing cause poor facial growth and malocclusion.

More recently, published articles relating to MRC's appliances have proven their effectiveness in treating varying malocclusions.
