Abstract

La présente invention concerne un capteur pour mesurer une pression, qui est conçu de manière à pouvoir mesurer des pressions dans différentes zones de la cavité orale qui peuvent causer une malocclusion d'une dent ou série de dents, c'est-à-dire des pressions telles que celles exercées entre les lèvres et les dents ainsi qu'entre la langue et les dents et les forces de mastication des molaires, de manière à produire un procédé servant à étudier les effets de telles pressions sur une malocclusion, et également pour une chirurgie de redressement de dent efficace ou le maintien et la surveillance d'une dentition normale après chirurgie de redressement en utilisant les pressions mesurées en tant que données. A titre de moyen pour résoudre ce problème, la présente invention comprend un capteur pour mesurer la pression en utilisant un matériau tel qu'une résine silicone qui n'est pas nocive pour le corps tout en ayant une bonne élasticité et étant souple, et le capteur pour mesurer une pression comprend un ballonnet formé avec une cavité centrale sur un côté du tube de raccordement formé avec un trou de décharge d'air et, lorsque le ballonnet est comprimé lorsqu'une pression à l'intérieur de la cavité orale doit être mesurée, l'air à l'intérieur de la cavité centrale passe par le trou de décharge d'air et est expulsé de telle manière que la pression puisse être mesurée par excitation d'un manomètre ; et la pression mesurée par le manomètre est appliquée à un système de commande et un logiciel de mesure disposés dans un ordinateur, de sorte que la valeur de pression mesurée soit affichée et que la valeur de pression mesurée soit transmise via un système de sortie et puisse ensuite être utilisée en tant que donnée pour le redressement de dent ou donnée pour maintenir et surveiller une dent ou des dents redressées.
