“…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.…”

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.

“…The CRP and CSP have been determined by electrognathography in a number of studies. George (1983) described CRP, in three dimensions, to be 2·9 mm, below, 0·3 mm posterior and 0·5 mm lateral to IP. Rugh & Drago (1981), Howell (1986) and Rivera-Morales & Mohl (1991) have reported the vertical dimension of CRP as 2·1, 2·3 and 2·6 mm, respectively.…”

Two subject groups had their mandibular positions determined, using an electrognathograph, at the clinical rest position (CRP) and at the closest speaking position (CSP). They were classified into a toothwear (largely of attritional origin) group (n=30) and a non-toothwear, or normal, group (n=60). The mean CRP deduced for the groups was similar in all three dimensions and found to be just less than 2 mm open from and 0.6 mm posterior to intercuspal position (IP) and approximately in the midline. The CSP, in two dimensions, of the toothwear group was significantly closer to IP than that of the normal group. The vertical component of CRP and CSP was similar for the normal group but CSP was significantly reduced in comparison to CRP for the toothwear group. The most forward component of CSP was significantly more anteriorly placed than was that of CRP. Although there was a pronounced inter-individual variation the results suggest toothwear, of long acting aetiology, has less affect on CRP than on CSP.

“…Both occlusal scheme (Beyron, 1964;Gibbs et al, 1971;Gillings etal, 1973;Neill & Howell, 1986;Michler etal, 1987;Proschel, 1987), and the sex of the subject (Howell, 1987) have been shown to effect mandibular displacement. George (1983) suggested that to provide some degree of consistency within the measurements of jaw movements, a standardized occlusal relationship should be adopted.…”

In 10 male and 10 female adults jaw movements and muscle activity were monitored during chewing. Subjects had a Class I occlusion and fluent unrestricted jaw movements; non exhibited signs or symptoms of craniomandibular disorders. Recordings were made on two occasions separated by 2 weeks. Within each recording session the subjects carried out a number of tasks under direction, including eating nuts and gum. The jaw movements were monitored with a Sirognathograph which had been interfaced to a computer for data logging and analysis. A computer program identified each chewing stroke and after scrutiny a data base was constructed of measurements from a subset of 4447 suitable strokes. Mean values of 10 parameters selected to describe jaw movements during chewing were entered into an ANOVA. This indicated that the major contribution to variance was due to the subject from whom the data was recorded. This intersubject variability is well known, but can its separation from the other contributions to the variation within the data be assessed? To provide an estimate of the spread of data the variance for each parameter was calculated, transformed and these values entered into an analysis of variance. All subject differed significantly in their chewing movements from one another. But 15 of the 20 subjects showed a greater degree of consistency than the other five: they exhibited good inter- and intra-recording reproducibility. The food being eaten made a major contribution to the variability. The timing of the chewing strokes was also more consistent than the dimensions of the chewing envelope.
