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
