초록

Purpose: The goal of this study is to examine the effect of articulation treatment using Oral Motor Training (OMT) on articulation accuracy and distortion errors of children who have speech sound disorders with class III malocclusion. Methods: Three children with class III malocclusion in the stage of deciduous dentition aged from 6;0-6;3 (year;month) participated in this study. These 3 children commonly exhibited unilateral mastication, mandible laterality on jaw movement and especially distortion errors of lateralizing for alveolar and palatal consonants mainly in vowel /i/ environment. Articulation therapy using OMT for both of improved non-speech and speech movement involved in target sound production was provided. The ABA design of single case experimental design was used. The articulation accuracy and the frequency of lateralization distortion errors at both of the word and sentence level were measured within baseline (A1), intervention (B), and maintenance (A2) phases. Results: It was found that all participants showed the higher articulation accuracy and the lower frequency of distorted lateralization errors for alveolar and palatal consonants at the both of word and sentence levels in intervention phases than in baseline ones and also these effects maintained after intervention. Conclusion: It was concluded that the OMT targeting appropriate non-speech and speech movement might be beneficial for young children who have class III malocclusion.
