Development of Phonetic Tests in Order to Improve the Functional Impression Technique in Total Edentation
This study is based on the idea that muscles on the periphery of total edentulous prosthetic field as well as the muscles mobilizing the mandible could contribute to a greater extent to the improvement of the quality of prosthetic part created. In this paper the authors aims on the basis of an interdisciplinary phonetic study in general linguistics to develop phonetic tests capable of modelling in the best conditions the edges of the mandibular port-imprint and the entire neutral zone of the dental corridor. Material and methods. The study included 20 patients, consisted of 10 females and 10 males. All the subjects are edentulous patients uni or bimaxilary and required complete dentures. We present the choice of phonetic tests for modelling lateral functional mandibular areas (buccal and lingual) and we select the most suitable isolated phonemes, and phonemes assembled a certain order, in order to give greater strength to the modelling power of the imprint. Results. The average value obtained for the vertical dimension of occlusion are 64,4 mm for males and 58,1 mm for females. Conclusions: The use of phonetic method for determining the vertical dimension of occlusion and for modelling the edges of the custom tray is simple and easy to perform.
