Diapositive 1
Froggymouth and Invisalign, by Dr Couchat


End of treatment

Michelle, 50, had an anterior open bite and refused to undergo surgery. She had a wide anterior open bite (5 mm) from canine to canine with maxillary endoalveolia. These two signs testify to the patient's lingual dysfunctions, notably atypical swallowing, in which an excessive contraction of the buccinator muscles can be observed (causing endoalveolia) along with tongue thrust (leading to the anterior open bite).
The treatment plan will therefore consist in getting the patient out of the dysmorphofunctional spiral through treatment to rehabilitate swallowing with Froggymouth and correcting the anterior open bite by egress of the incisors combined with retraction of the mandibular incisors and molar ingress.
At the end of treatment, the patient's atypical swallowing was rehabilitated and the anterior overlap was acceptable. The patient still presents class I occlusion. Bonded wires were placed on both maxillae and regular monitoring is needed to prevent functional recidivism.

Diapositive 1
Froggymouth and orthopedic "toboggan", by Dr Fellus

Since Marc was 2½ years old, every practitioner they saw told his parents that there was nothing they could do and they would have to wait until he was old enough to undergo surgery.
Marc was 4 when Dr Fellus suggested a different way of treating this severe retromandibulia - an orthopedic "toboggan" and the use of Froggymouth to stimulate the proliferation of pre-chondroblast cells and renewed mandibular growth.
Two year later, Marc is class I and will not be needing surgery.

Clinical studies

In 2015, an independent clinical study was carried out by Dr. Cornut atIn 2015, an independent clinical study was carried out by Dr. Cornut at the Lille University Medical Center. An 80-point increase in the number of patients who acquired secondary swallowing was shown after 10 weeks, three-quarters of whom had automated this new praxis.
A significant decrease of mouth breathing has been noted (60%).

Functional MRI


This functional MRI was performed on a 35-year-old patient by Dr. Pans at the Liège University Medical Center. It shows the sensorimotor areas of secondary swallowing and automation of the praxis after 1 month.

This functional MRI was performed on a 6-year-old child by Dr. Gaillard at Necker Hospital in Paris.

It highlights stimulation of the area controlling secondary swallowing starting with the first use of Froggymouth.
