Assessing the impact of complete dentures on speech and swallowing

Experimental Study of Tongue/Palate Interactions Using Upper coMplete dEnture

Not applicable Interventional Hospices Civils de Lyon · NCT03966131

This study tests how new complete dentures affect speech and swallowing in people who have lost all their teeth, comparing those who are new to dentures with those who have been using them for over a year.

What this trial studies

This project evaluates how new complete dentures affect speech production and swallowing in edentulous patients. Using sensors placed in a duplicate prosthesis, the study measures pressure and acoustic signals during speech and swallowing tasks. The research focuses on two groups: those wearing dentures for the first time and those who have been using them for over a year. The data collected will help map the mechanical pressures exerted by the tongue on the palate, providing insights into the functional outcomes of denture use.

Who should consider this trial

Good fit: Ideal candidates are bimaxillary edentulous patients over 18 years old requiring a prosthesis or those who have had a prosthesis for at least one year.

Not a fit: Patients with speech or neurological disorders, or those who are not native French speakers, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the design and functionality of complete dentures, enhancing speech and swallowing for patients.

How similar studies have performed: While similar studies have explored denture impacts, this specific approach using sensor technology for detailed pressure mapping is relatively novel.
