RESUMEN
BACKGROUND: Studies have demonstrated a relationship between dental malocclusion and posture defects. The aims of the study were to present (1) the effect of a physiotherapeutic approach to a patient with a distal occlusion defect with the use of a set of exercises to strengthen the muscles responsible for mandibular protrusion, and (2) a non-invasive and easy-to-use method to monitor the effects of therapy. METHODS: Five year old girl with a distal occlusion and with a low basic postural tone was referred to physiotherapy. A therapeutic program i.a. concerning a strengthening of the temporomandibular joint muscles with the use of a flexible tape was proposed. To assess the functional changes of the masticatory apparatus a photoanthropometric method was used. In side-face photos, proportions of 2 linear measurements and values of two angles on the first day of therapy, after 2 and after 4 months of exercises, with the mandible located freely and in the maximum protrusion were compared. RESULTS: A comparison of indices and angles showed a marked improvement in mandibular mobility already after two and four months of the exercises. Using the elastic resistance tape in addition to general developmental exercises allowed for increasing the mobility in the temporomandibular joint. CONCLUSION: Malocclusion should not be considered separately, without taking into account the body posture. The work of the physiotherapist can benefit the orthodontist, correcting postural defects and consequently affecting malocclusion. A comparison of linear measurements and angles can be used to assess the progress of the therapy.
