[Presentation of a prototype dynamic palatography for measuring the downforce of the tongue on the palate in the swallowing time].

Abstract

The position of the tongue and the forces which it exerts on its dental and osseous environment would be responsible for a certain degree of dysmorphosis. However there is not tool usable in clinic which makes it possible to check the reality of the forces exerted by the tongue on the palate. We developed a prototype made up of an artificial palate in rigid resin including of pressure sensors and we report the feasibility of a study on healthy subjects. The sensors allow indeed of following dynamic visible differences between various "maneuvers" during the swallowing of a water mouthful. The tool will be now adapted for a clinical study comparing of the subjects with and without lingual dysfunction
