Edentulism is defined as “the state of edentulism; ; without natural teeth. The consequences of tooth loss were described in multidimensional views. Although edentulism is not a life-threatening condition, it is a debilitating and irreversible condition and is described as the "final marker of an oral health disorder." It is known to directly affect facial structures, eating, the ability to perform functional tasks such as eating, speaking and socializing. Although the incidence of edentulism has decreased over the past decade, with the advent of science and technology, the average life expectancy has increased steadily. Edentulism therefore remains a major disease worldwide, particularly among the elderly population. The conventional complete denture (CD) still remains the first choice of treatment for the rehabilitation of the isolated edentulous maxilla. A complete denture is defined as “a fixed or removable dental prosthesis that replaces the entire dentition and associated structures of the maxilla or mandible.” Say no to plagiarism.

Since it is claimed that complete dentures alter the resonance cavity of the vocal tract, many authors have reported speech disorders in patients with complete dentures. Therefore, for the optimization of one's performance in speech production, knowledge of the dynamic contacts of the tongue on the prosthesis is fundamental. However, a number of experimental systems have been designed in the recent past. the number of studies available is limited, particularly studies investigating dynamic measurements of tongue force exerted on complete dentures during speech. Mainly, through this case report, our objective is to illustrate the usefulness of a new experimental device, to be used in edentulous patients, to quantitatively evaluate the impact of the complete prosthesis on speech production. The objective of this study is the detailed presentation of the spatial and temporal mapping of the contacts applied by the tongue to the prosthesis. More specifically, the aim of this study was to evaluate the differences in contact dynamics in French stops in a patient with a complete denture. Tongue-palate contact was assessed by measuring pressure and time patterns characterizing stress signals and acoustic signals based on several parameters related to consonant production. It is important to emphasize that this patient had been using prostheses for more than three months and that his adaptation to the prosthesis was complete. Furthermore, the transducers and strain gauge wires produced no additional changes in the morphology of the artificial plate, we hypothesized that no disturbance was caused. at the joint. Therefore, in this study we managed to record tongue-palate interaction under conditions that were, to our knowledge, as close as possible to the natural physiological state of the complete denture user..
