Team develops tongue prosthesis to help colleague who had tongue cancer speak again

About the solution

Shogo was assisted by a team of researchers from the university after Kenichi had most of his tongue surgically removed. As he was no unable to speak, he asked Shogo to help him by creating a new prosthesis that would allow him to speak.

The professor started working on the challenge by looking into existing tongue prosthesis and only found one paper about the subject, in Japan, in which the artificial tongue was part of a denture and could not be moved.

“Developing an oral prosthesis is a painstaking process for patients. This time, we could create a really good prosthesis quickly thanks to Kozaki, who is a dentist himself. He tried many different versions of the prosthesis and offered us detailed feedback”, the inventor explained.

Shogo Minagi’s team developed a solution having into account that whenever someone speaks, the tongue has to touch the palate, but the problem was that people with no tongue are not able to perform this action.

The new prosthesis is made of resin, moves up and down in the mouth as it is connected to the back teeth by a wire. The user controls the device by pushing it with the remaining base of their tongue.

The team leader also added that some users can wear a resin filling over their palate to make it easier for the device to make contact.

Now, the team hopes that the innovation becomes available worldwide - and that’s why they’ve used materials that are already widely used by these industry professionals.

“We have used materials that are already widely used, so any dental technician can make this type of prosthesis. We would like to share our know-how widely with clinics nationwide, to help as many people as possible”, he expressed.

At the time of the development, at least four people were about to get these artificial tongues.

About the author

Shogo Minagi, born and living in Japan, is a professor of dentistry at Okayama University who invented the world’s first movable tongue prosthesis. Shogo created this device in 2015, at the request of his colleague Kenichi Kozaki, also a dentistry professor, who had been diagnosed with tongue cancer in 2014 and was unable to speak because he had most of his tongue removed.
