SIZE GUIDE

HORIZONTALLY, THE FROGGYMOUTH MUST BE SLIGHTLY
SMALLER THAN THE SIZE OF THE PATIENT'S MOUTH

THE ACTION OF THE FROGGYMOUTH IS TO INHIBIT THE FACIAL NERVE
AND THUS PREVENT CONTRACTIONS OF THE LABIO-MENTAL AND
JUGAL MUSCLES DURING SWALLOWING.

THE INHIBITION OF THE FACIAL NERVE WILL PROMOTE THE ACTION OF ITS ANTAGONIST, THE TRIGEMINAL NERVE. THE LATTER CONTROLS THE RESPIRATORY CENTERS IN THE PONTINE TEGMENTUM THROUGH ITS SENSORY NUCLEUS AND WILL THEREFORE PROMOTE RESTORATION OF NASAL BREATHING.

YOU UNDERSTAND THUS WHY A HORIZONTALLY LARGER FROGGYMOUTH THAN THE INTER-COMMISSURAL GAP WILL NOT BE SUITABLE.

THUS, IN CASE OF DOUBT BETWEEN TWO SIZES,
WE WILL ALWAYS RECOMMEND THE SMALLER ONE.

THIS WILL AVOID STRETCHING THE LIPS AT THE COMMISURES
AND THUS STIMULATING THE FACIAL NERVE.
