Orthodontic treatment and voice and wind instrument performance

Abstract

Orthodontic therapy is the primary treatment of dentofacial anomalies. Using internal and/or external appliances, orthodontic therapy aims to improve dentofacial balance through restoration of soft tissue, dental, and skeletal symmetries. Treatment-induced changes in the volume and cross-sectional area of the upper airway can lead to marked alterations in palatal morphology and velopharyngeal function, thus resulting in voice and articulatory problems, and difficulties playing wind instruments. Indirect effects secondary to pain during the course of therapy and/or disorders in the temporomandibular joint also may jeopardize voice. Wind instrumentalists with dentofacial anomalies need special attention. The choice of instrument can counteract the benefits of orthodontic therapy and precipitate difficulties in embouchure. Early intervention is recommended, particularly in subjects with pre-existing difficulty in performance.
