Research related to stomatognathic functions

　In the classroom, we carry out basic and clinical research on the diagnosis and treatment of stomatognathic function such as chewing, swallowing, and breathing, and muscle function therapy (MFT) using jaw movement measurement devices, electromyograms, occlusal force meters, NIRS (near-infrared spectroscopy), fMRI, and a self-developed device for determining continuous sealing of the lips, etc.

1. Research regarding sealing of the lips
2. Stomatognathic function and higher brain function research
3. Temporomandibular joint research

1. Research regarding sealing of the lips

　Muscle function therapy in orthodontic treatment improves the balance of power between the orbicularis oris muscle and the tongue, and is effective in improving malocclusions and stabilizing occlusion as a result of treatment. Lip training, a type of lip closure training, is part of this treatment. So far, we have discovered two different types of orbicularis oris training methods to enhance muscle strength and endurance.
We have also investigated whether endurance enhancement training is effective in achieving lip closure for people with lip closure difficulties in every-day life.

2. Stomatognathic function and higher brain function research

We are currently carrying out elucidation of higher brain functions regarding stomatognathic functions (chewing, pronunciation, swallowing, etc.) and analysis of higher brain functions such as emotional changes and thoughts regarding occlusal conditions and skeletal morphology. We are also analyzing brain functions related to pain in orthodontic treatment.

3. Temporomandibular joint research

Research regarding the relationship between temporomandibular disorders typified by TMJ arthrosis and growth development, malocclusion, and orthodontic treatment continues with the use of EMGs, jaw movement measuring devices, and examination equipment.
Additionally, we are also developing a therapeutic splint for TMJ arthrosis.
