Objectives:
This study aimed to identify speech sound disorders in children with class III malocclusion and evaluate the effect of orthodontic management and complementary speech therapy sessions on correction of these disorders.
Subjects and Methods:
A sample of eighteen patients with skeletal class III malocclusion and speech sound disorders. All patients were treated with maxillary protraction using facemask accompanied with rapid maxillary expansion using hyrax expander. Speech assessment for all children was performed at three times: T1(before orthodontic management), T2 (6 months after orthodontic management), T3 (after giving complementary speech therapy sessions).
Results:
Results after three different times of speech evaluation showed that there was no significant difference between (T1) before and (T2) after orthodontic treatment for all types of speech impediments, with all cases being the same. while, there was a significant improvement in all types of speech impediments for all patients after speech therapy (T3).
Conclusion:
Complementary speech therapy sessions after orthodontic management showed a significant improvement in all types of speech impediments than orthodontic treatment alone for children with class III malocclusion accompanied with speech sounds disorders.
