“…The belief that the closest speaking space is smaller than the FS was not supported by that study. More recently, Meier et al [19] concluded that none of the registration methods studied display clear-cut superiority to the others. Therefore, nonocclusal advantages, such as airway patency, may help the clinician decide on which registration protocol to follow.…”

Patients with temporomandibular dysfunction (TMD) require antero-posterior (AP) correction of mandibular position inter alia. Determination of the limit of the AP correction using a sibilant phoneme registration (SPR) protocol is essential in not increasing muscular tonus. The aim of this study is to investigate the effect of a SPR protocol on the upper airway. Using acoustic pharyngometry data, mean airways of 46 adults undergoing treatment for TMD were reconstructed in 3-D and analyzed using finite element analysis and principal components analysis. When the mean baseline functional residual capacity (FRC) airway was compared to the mean collapsed residual volume (RV) airway, a 25% reduction in the 3-D upper airway was demonstrable (p < 0.01). When the mean baseline FRC airway was compared to the mean airway with SPR (FRC-SPR), a 12% increase was found at the oropharyngeal junction of the 3-D airway, but this finding failed to reach statistical difference. Similarly, when the mean FRC-SPR airway was compared to the mean RV-SPR airway, the amount of collapse was reduced to 16% but again no statistical difference was found. In contrast, when the mean RV airway was compared to the mean RV-SPR airway, a 15-18% increase was found (p< 0.05). It is concluded that the use of a SPR protocol may be useful in improving upper airway RV in patients, during treatment for TMD.

“…The precision of speech articulation is related to the freedom of the mandibular movements, modifying the spaces in order to allow the different articulatory positions of each sound (2). Furthermore, analysis of the mandibular movements during speech has been a useful method for determining the vertical dimension of dental occlusion, anterior guideline and tooth position in the rehabilitation treatment of patients (3). Mandibular movement dimensions are also important variables in the evaluation of speech patterns (4).…”

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.

“…24,25 Additional advantages of electronic axiography is avoidance of radiation exposure and real-time threedimensional representation of mandibular movements. 26 Most of the studies that observed TMJ anatomy and function used one specific sagittal condylar inclination angle 14,17,19,27,28 describing the left and right joints. Existing data about intraindividual variations of the sagittal condylar path are scarce.…”
