Clinical cases

Correction of an incisor open bite in
two months of wearing Froggymouth

Julia, 4 years old – Case treated by Dr. P. Fellus

This four-year-old little girl showed an isolated incisal open bite. She wore the device between 31st of March and 1st of June. The dysmorphic feature continued to spontaneously correct itself, and the result obtained on 11th of October lets us foresee definitive physiological dental occlusion without any orthodontic intervention.

Froggymouth and Aligners

Michelle, 50 years old – case treated by Dr D. Couchat

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 had therefore consisted in getting the patient out of the dysmorpho – functional spiral through treatment to rehabilitate swallowing with Froggymouth and correct 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 relapse functional recidivism.

Correction of an open bite in
3 months of wearing Froggymouth

Male patient, 6 years old – Case treated by Dr. Rafi Romano

A 6-year-old child with an open bite, mouth breathing, and hypotonic facial muscles received treatment at an orthodontic clinic of Dr Rafi Romano. The FroggyMouth was prescribed for 15 minutes per day to strengthen the lip muscles and change the tongue behavior. After three months of using FroggyMouth, the child’s open bite had closed, and the child’s mother reported improved breathing and mouth closure not only during the FroggyMouth sessions but also throughout most of the day. NO additional treatment was used in these 3 months.
