Evaluating the Impact of Myofunctional Therapy on Orthodontic Treatment Outcomes

Abstract

ABSTRACT Background: Myofunctional therapy has gained attention as a potential adjunct to orthodontic treatment, focusing on improving orofacial muscle function and balance. Despite its increasing popularity, the precise impact of myofunctional therapy on orthodontic treatment outcomes remains to be fully elucidated. Materials and Methods: A retrospective cohort study was conducted, involving 80 orthodontic patients aged 8–18 years, divided into two groups: Group A received orthodontic treatment alone, while Group B received orthodontic treatment combined with myofunctional therapy. Orthodontic treatment outcomes were assessed based on occlusal stability, facial aesthetics (evaluated through standardized photographs), and patient-reported satisfaction scores. Posttreatment stability of occlusion was assessed using the peer assessment rating (PAR) index, with lower scores indicating better occlusal outcomes. Results: The results indicated a significant improvement in orthodontic treatment outcomes among patients who received myofunctional therapy in addition to orthodontic treatment. Group B demonstrated a mean decrease of 25% in PAR index scores compared to Group A, indicating superior occlusal stability posttreatment. Facial aesthetics were also notably enhanced in Group B, with a higher percentage of patients achieving harmonious facial profiles than Group A. Additionally, patient satisfaction scores were significantly higher in Group B, with 85% of patients reporting high satisfaction levels, compared to 60% in Group A. Conclusion: Myofunctional therapy as an adjunct to orthodontic treatment has a positive impact on treatment outcomes, including improved occlusal stability, enhanced facial aesthetics, and increased patient satisfaction.
