Abstract

The speech is a very complicated process which can be essentially influenced by a small modification of an individual, shared component. As components we designate the teeth, the tongue and the palate and further anatomical structures which perform together during articulation and influence themselves. In such a way, the tongue leans on the palate relief to form specific fricatives , which can cause a modification of the initial situation for carriers of loose tooth-substitutes with full dentures which cover the palate completely or partially. Accordingly, a full denture must also guarantee a not disturbing articulation in addition to a functional and aesthetic rehabilitation. The aim of this study was to examine the influence of the design on the palatal appliance instrumentalphonetically and to formulate therapeutic approaches with the developed method by W. Wisser [2000]. Eleven female and nine male probands were tested for this examination, who had another full denture pair in addition to the actual teething substitute. Besides of the capability to speak a dialect-free German and to the position to have a well property of reading, the unlimited hearing property of these probands were also checked audio metrically. In agreement with the probands, the surface of the artificial palate of the second full denture was modified after the production of a palatogram as follows: · polished surface of upper complete denture · median palatine rugae (regio Papilla incisiva, regio 15/25) · median and transversal palatine rugae on articulation place · median and transversal palatine rugae before articulation place · median and transversal palatine rugae after articulation place · modified Snow bulge · roughened surface The probands had to read a text with each of these modifications. By using a DAT-recorder and a microphone fixed on the headset high fidelety recordings of these voice-tests were made. By a computer-assisted frequency-analysis according to the principle of the Fast Fourier transform (FFT), also to the subsequent statistical evaluations by the Wilcoxon- and Friedman-test it was possible to prove objectively and reproducible form differences in articulation of the examined consonants as a result of the modification of the worn palate-plate in each case. In this research there could not be seen any statistically significant deviations through the palatal-appliance-modifications in the sounds ?k?, ?f?, ?ts?, ?s? and ?C?. This was rather unexpected for the loud ?s?, however it shows the compensation-ability of articulation. In this examination differences in articulation could be proved in the sounds ?S?, ?n? and ?l?, but normally only by putting on the transversal palatine rugae. The rough surface in the area of the articulation-zones of the examined tones, wax bulges in the palatine field of the first premolar teeth, as well as the placing of a median palatine rugae were not evaluated statistically significant for articulation. For the first time a study shows statistically saved results for the influence of the palate appliance to full denture on articulation.The speech is a very complicated process which can be essentially influenced by a small modification of an individual, shared component.
