“…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. Howell (1986) described the CSP as 3·1 mm from IP and 1·5 mm anterior to IP.…”

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.

“…simultaneously registering the interocclusal space. This space is small (average value is 1-2 mm -Silverman 14, 15 , 2.6 mm -Benediktsson 33 , 3.1 mm -Howell 34 ) and the lips are close together so it is not possible to observe the interocclusal space. All the authors who have used the phonetic method for determining the VDO aimed at getting the value for the SA and then that value was used to obtain values f or VDO.…”

“…The present study questions this belief, since it was found that the inverse was true. It was stated that the closest speaking space is greater than the FS in dentate subjects 10,14 . Similarities between SSS and FS were shown in several studies 3,8,12,21 .…”

ABSTRACT:The purpose of this study is to assess the relation between the speaking space of the /s/ sound and the freeway space in two subject groups. One group had natural dentition (Group I, n = 61) and the other comprised complete denture wearers (Group II, n = 33). The analysis was done by means of a jaw-tracking device (K6-I Diagnostic System, Myotronics Research Inc., Seattle, WA, USA). Freeway space was determined by asking the subjects to occlude from the postural rest position. Speaking space of /s/ was measured during the pronunciation of the word "seis" and comprised the mean distance from the /s/ speaking position to maximal intercuspation. A weak correlation was found between the speaking space of /s/ and the freeway space in Group I (r = 0.41, p < 0.01), but in Group II, the correlation was stronger (r = 0.75, p < 0.01). The speaking space of /s/ and freeway space were different in Group I, but statistically similar in Group II (paired t-test, α = 0.05). It can be suggested that anatomic changes following prosthetic procedures caused a functional adaptation which resulted in more similar values for the speaking space of /s/ and the freeway space. DESCRIPTORS: Phonetics; Dental occlusion; Denture, complete; Jaw relation record. RESUMO:O objetivo deste estudo foi investigar a associação entre o espaço de pronúncia do som /s/ e o espaço funcional livre em dois grupos de indivíduos. A amostra foi classificada em dentados (Grupo I, n = 61) e portadores de próteses totais (Grupo II, n = 33). A análise foi realizada empregando um instrumento cinesiográfico (K6-I Diagnostic System, Myotronics Research Inc., Seattle, WA, EUA), capaz de fornecer registros dos movimentos mandibulares. O espaço funcional livre foi determinado solicitando-se ao indivíduo que ocluísse a partir da posição de repouso postural. O espaço de pronúncia do /s/ foi aferido durante a pronúncia da palavra "seis", registrado como a posição mandibular média para o som /s/ em relação à máxima intercuspidação. Houve uma fraca correlação entre o espaço funcional livre e o espaço de pronúncia do /s/ para o Grupo I (r = 0,41, p < 0,01), mas uma correlação relativamente forte para o Grupo II (r = 0,75, p < 0,01). O espaço funcional livre e o espaço de pronúncia do /s/ foram diferentes no Grupo I, mas estatisticamente semelhantes no Grupo II (teste t pareado, α = 0,05). Dessa forma, pode-se deduzir que mudanças anatômicas após o procedimento protético provocaram uma adaptação funcional, sendo que esse processo adaptativo aproximou as duas variáveis -espaço de pronúncia do /s/ e espaço funcional livre.
