Evaluation of Denture Functions in Complete Denture Wearers by Using Electromyography and Pressure Distribution Measuring System.

Abstract

Abstract:The biting forces from integrated EMG and the pressure distributions at the denture basemucosal interface in three complete denture wearers were recorded simultaneously under the regular clenching condition.In order to measure the stress of the tissue bearing pressure, duplicated mandibular dentures containing six pressure sensors on basal surface were constructed.Integrated EMG and pressure distributions were measured at the same time and analyzed on time by using digital processing system. The conclusions as to the change of pressure distribution and calculating the biting force by proceeding occlusal adjustment were as follows:1. It was possible that present method of calculating the biting force from integrated EMG and pressure distribution by pressure sensors could be used for complete denture wearers.

Influence of denture treatment on brain function activity

“…It has been reported that the occlusal contact area and occlusal force are closely correlated with the masticatory efficiency [43][44][45][46]. These results suggest that subjects could safely masticate due to an increase in the occlusal contact area and an adequately distributed occlusal force.…”

Influence of Occlusal Force on Electroencephalograms in Edentulous Patients

“…Furthermore, deterioration of masticatory muscle function can lead to a disruption of the α‐γ coupling mechanism controlling jaw movement, which could undermine brain function activity . A strong correlation between mastication function and occlusal force suggests that an improvement in masticatory function through complete denture treatment can lead to increased occlusal force, and eventually, enhance synaptic/neuronal function in the brain.…”
