Santé orale chez le sujet âgé édenté : enjeux et perspectives en prothèse odontologique

Abstract : This work focuses on the links between the edentulous elderly person oral health and his or her diet. Indeed, in the elderly, a regular and diversified food intake is to be sought to prevent protein-energy malnutrition. However, the rehabilitation of denture by removable dentures does not optimize or little diversification of food. The placement of implants by implant-retained prosthesis or scope remains restricted in this population. As such, one of the possible therapeutic solutions is the transformation of the removable prosthesis in implant-retained prosthesis by mini implants. The impact of this new procedure on masticatory function and patients' oral quality of life was evaluated by a follow-up study. This evaluation showed that the implant-retained prosthesis improves the masticatory capacity of subjects and its oral quality of life, but the masticatory efficiency remains well below that observed in elderly dented subjects.Subsequently, new therapeutic procedures using CAD / CAM (Design and Computer Aided Manufacturing) were developed and evaluated in rehabilitated subjects in the Odontology Department of the Estaing Hospital. The benefits of CAD / CAM in maintaining the oral health of the elderly were thus objectified. As a continuation of this work, new CAD / CAM procedures for the oral rehabilitation of the edentulous subject are currently being evaluated.Moreover, a quality food intake involves the bringing into play of different oral perceptions. The interactions between oral health impairment in the elderly, chewing and orosensory perceptions are therefore highlighted by a review of the literature. Factors affecting the food intake of the elderly are also identified. The ultimate goal is to work on the characteristics of the consumed food (nature and texture) to facilitate its chewing, modify its orosensory perception and thus certainly promote its consumption.
