Pre-orthodontic Orofacial Myofunctional Therapy With Myosimple: A Case Report

This case report describes how to begin multi-attachment or aligner orthodontic treatment with a phase of orofacial myofunctional therapy (OMT) combined with the use of Myosimple, a new prefabricated functional appliance (PFA). An 11-year-old patient presented with a Class I malocclusion tending towards Class II Division 2, 100% incisor overbite, maxillary and mandibular crowding, and atypical lateral swallowing. Treatment began with an OMT phase combined with the use of a Myosimple, which was worn for an average of 13-14 hours per day during the week, i.e. during sleep and during the day outside of school, with more regular wear at weekends. The Myosimple was immediately well accepted and worn thanks to its innovative design and very small size. Within three months, wearing the Myosimple corrected the incisor overbite, improved the coordination of the dental arches, reduced maxillary and mandibular crowding, and enabled functional swallowing. This improvement in the shape and relationship of the dental arches then allowed for more effective and faster continuation of treatment with multi-attachments or aligners.
