Construction of Complete Denture below the Floor Level Load
Pressure Measurement System with Film Type Sensor

Abstract

Dentures can be made by considering the load pressure distribution, and it is thought that the maintenance of the state of the mandible bank is possible by clarifying the dentures' load pressure distribution below the floor level. This study aimed to insert a film pressure distribution measurement sensor sheet under the denture floor mucous membrane, and to construct a system to measure in real time the denture's load pressure distribution below the floor level mucous membrane in the mouth. The development of the sensor, the denture load pressure measurement below the floor level tissue, and the system for synchronization and digital video shooting were developed as the first stage.
The pressure distribution measurement sensor sheet (Nitta) was improved, the sensor was produced, and installed on a full denture. There were six sensor installation sites in total. The bite of the center occlusion and right lateral occlusion was measured five times.
Especially, the front tooth load pressure was the highest in the centric occlusion and the right lateral occlusion. The load in the right lateral occlusion indicated a significant load increase to the right. This approximated to the basic research result, and showed a positive correlation.
The load pressure distribution below the denture floor level in the mouth was effectively measured in real time using the updated sensor.
