“…These results are close to those found by other studies for the closest speaking space 2,4 and for the SSS 8 . Gillings 9 reported the closest speaking space as being 2.5 mm, although this value can be higher than real because the equipment used could have exerted significant weight over the mandible.…”

“…According to Silverman [26][27][28] , the sibilant sounds are the ones that most constantly bring the mandible to the closest speaking level. The sibilants are high-frequency sounds produced by a stream of air directed through a minimal incisal separation 4 and an example of it is the /s/ sound. Its mandibular speaking position has been used for vertical dimension evaluation and also as a parameter for placing anterior artificial teeth 7,15,18,19 .…”

RESUMOwww.fob.usp.br/revista or www.scielo.br/jaos he purpose of this study is to determine the association of speaking space of /s/ sound with vertical and horizontal overlaps for two subject groups. Group I comprised 61 subjects with complete permanent dentition and Group II comprised 33 complete denture wearers. They had their mandibular movement determined by using an electromagnetic method. Speaking space of /s/ was obtained from each subject as they were instructed to say the word 'seis' three times. The mean interocclusal distance during /s/ production was considered the speaking space of /s/. Vertical and horizontal incisor overlaps were also measured. The mean value of speaking space of /s/ was 2.22 mm (± 1.38) for Group I and 2.61 mm (± 1.53) for Group II. In Group I, significant correlations were found between the speaking space of /s/ and vertical overlap (r=0.36, P<0.01), and between speaking space of /s/ and horizontal overlap (r=0.45, P<0.01). In Group II, no significant correlation was found between speaking space of /s/ and the overlaps. It was concluded that incisor overlap had a direct influence on the measure of speaking space of /s/ for dentate subjects, but this association was not present for complete denture wearers.

O Grupo I foi formado por 61 indivíduos com dentição permanente completa e o Grupo II por 33 usuários de próteses totais. Todos tiveram seus movimentos mandibulares determinados por um método eletromagnético. O espaço de pronúncia do /s/ foi obtido em cada indivíduo conforme eram instruídos a dizer a palavra 'seis' por três vezes. A distância interoclusal média durante a produção do /s/ foi considerada como sendo o espaço de pronúncia do /s/. Os trespasses incisais vertical e horizontal também foram mensurados. Os valores médios do espaço de pronúncia do /s/ foram 2.22 mm (± 1.38) para o Grupo I e 2.61 mm (± 1.53) para o Grupo II. Para o Grupo I, observou-se associação entre o espaço de pronúncia do /s/ e os trespasses vertical (r=0.36, P<0.01) e horizontal (r=0.45, P<0.01). Para o Grupo II, não foi encontrada nenhuma correlação significante entre o espaço de pronúncia do /s/ e os trespasses. Concluiu-se que o trespasse incisal teve influência direta sobre as medidas do espaço de pronúncia do /s/ em indivíduos dentados, mas esta associação não esteve presente nos usuários de próteses totais.

“…This movement must have been influenced by the anterior tooth wear, considering that the emission of /s/ sounds depends on the minimum of interincisal separation and consequently the relationship of upper and lower teeth (6,(9)(10). Moreover, sibilant sounds produce the mandibular position that comes closest to the maximum intercuspal position during speech (7).…”

This study described changes in mandibular movements during pronunciation of /m/ and /s/ sounds in Portuguese, in patients presenting dental wear before and after appliance insertion and tooth reconstruction. Subjects were divided into a control group of dentate patients and an experimental group of patients with incisal tooth wear due to bruxism. A magnetic jaw tracking device measured the jaw opening, and translations to left and right sides of the mandible during pronunciation of phonemes. Evaluations were carried out 1 week and immediately before appliance insertion; 24 h, 7, 30 and 60 days after appliance insertion; and 1 week and 1 month after tooth reconstruction. Data were submitted to two-way ANOVA, Mann-Whitney and Friedman tests (p<0.05). Jaw opening was different (p<0.05) for both sounds in all periods. The anteroposterior amplitude for /s/ showed differences immediately before and 1 month after appliance insertion (p<0.05). Lateral amplitude for the right side showed differences between groups after appliance insertion for /s/, and 1 and 2 months after appliance insertion for the /m/ (p<0.05). Volunteers with anterior tooth wear had a wider opening movement, and the movements during speech of /m/ and /s/ sounds were not changed after appliance insertion and reconstruction of teeth.

“…6,7 The phonetic method is based upon measurement of the interocclusal dimension (IOD) during speech or the pronunciation of certain sounds, e.g., [s] and [m]. [8][9][10][11][12][13] As a reference position selected to determine the OVD, some researchers suggest that this position would not be infl uenced by factors such as lips, teeth, and various types of prostheses. [10][11][12]14 The method of continuous phonation of [n] was recently used by Yamamoto et al 15,16 and Ohmori et al 17 Yamamoto et al 16 reported on the mandibular position during continuous phonation.…”

Influence of experimental palatal plate on mandibular position during continuous [n] phonation and at the physiologic rest position

et al. 2010

The purpose of this study was to clarify the influence of an experimental palatal plate on the mandibular position during continuous [n] phonation and at the physiologic rest position. Twenty healthy dentulous volunteers (10 males and 10 females, mean age of 24.4 years) were investigated. Three kinds of experimental plate with a thickness of 3 mm, 5 mm, and 8 mm were fabricated and used for each subject. The mandibular position was recorded by a K7 kinesiograph during continuous [n] phonation and at the physiologic rest position under normal conditions and when the three kinds of plate with different thickness were worn separately. The results showed that the mean interocclusal dimensions during continuous [n] phonation were 0.5 mm vertically and 0.4 mm anteroposteriorly under the normal condition. After insertion of an experimental plate, the interocclusal distance increased a little, but the difference was not statistically significant between the normal condition and any of the three experimental conditions. No significant difference was found between the male and female groups. Furthermore, no significant difference in the interocclusal distance at the physiologic rest position was found between the above comparisons. Within the limitations of this study, we concluded that the mandibular position during continuous [n] phonation and at the physiologic rest position was not significantly influenced by the experimental plates.
