Speech Articulation Problems Associated With Placement Of Orthodontic Appliances

Speech Changes Following Orthodontic Treatment With The Functional Regulator

“…That is, although there was slight variation in performance across evaluation sessions, the eventual scores approximated those obtained during the baseline recordings. The gradual adaptation to the appliance is similar to the findings reported by other investigators who studied speakers without cleft palate (Feldman, 1956;Erb, 1967). Speakers appear to adapt to alterations in their oral environment and re-establish articulatory production targets following a period of appliance wear.…”

“…An illustration of the functional regulator is presented in Figure 1. In the noncleft population, the functional regulator has been utilized to affect changes in the orofacial complex such as: increases of the transverse and sagittal intraoral space; increase of vertical intraoral space; anterior positioning of the mandible and/or maxilla; formation of new patterns of motor function; stimulation of muscle tonus; and development of a correct oral seal (Frankel, 1966;Frankel, 1970;Frankel, 1974;Graber and Neuman, 1977). When persons are fitted with various dental appliances, they must presumably adapt to the changes within the oral cavity.…”

“…Their findings indicated that appliance wear did result in articulatory production errors. Additional investigators (Feldman, 1956;Erb, 1967;Altmann, Gaydke and Schlegel, 1981) have also studied this phenomenon through sampling at periodic intervals. The results of the investigations are similar initially to the results of Garber and her group; however, disruptions are minimized after a short period of wear.…”

Effects of fixed labial orthodontic appliances on speech sound production

“…[2][3][4]14 The phonemes acknowledged to present lingering difficulties with articulation are /s/, /f/, /v/, /t/, /r/, /n/, and /l/ phonemes. 5,6,14 Feldman 15 presented the sole article containing data on the effects of labial fixed appliances in 1956 and reported an increase in errors immediately after appliance insertion, with resolution within weeks. Though useful, this study presents several shortcomings: small sample size, appliance variability, lack of sound error type and uniformity in evaluating sample readings, a lack of adult patients, and, finally, a lack of attention to malocclusions that may predispose one to maladaptation.…”

Der Einfluss kieferorthopädischer Oberkieferdehnplatten auf Sprechgeschwindigkeit und Artikulation

“…In der Literatur sind immer wieder Hinweise darauf zu finden, dass kiefer orthopädische Behelfe einen Einfluss auf die Artikulation haben (Cadenat et al, 1970;Erb, 1967;Feldmann, 1965). Dies muss vor allem deshalb berücksichtigt werden, da solche Geräte bei Kindern, deren Artikulation noch nicht gefestigt ist, therapeutisch angewandt werden müssen.…”
