A case study on myofunctional therapy and malocclusions created by oral habits

To demonstrate the effect of an orofacial myofunctional therapy intervention by an interdisciplinary team composed of a registered dental hygienist who is also a certified orofacial myologist (COM^®), a general dentist, and an orthodontist on the elimination of oral habits and changes in dental malocclusion.

This case study describes a 7-year-old female who underwent an individualized myofunctional therapy program and was given supervised education on a series of exercises targeting the muscles of mastication and facial expression over 5 months. Correct oral rest postures of the tongue and the lips were also established through therapy.

The intervention enabled the client to eliminate multiple oral habits, which corrected oral rest postures of the lips and tongue. This correction consequently improved the client's malocclusion and further prepared the client for future orthodontic treatment.

Myofunctional therapy facilitated the elimination of unfavourable oral habits that led to malocclusion. Eliminating oral habits better prepared the client for orthodontic treatment and retention. Use of an interdisciplinary team facilitates optimal client care.
