Summary

The relationship between form and function within the craniofacial complex has been investigated by several Authors. However, there is still controversy regarding the different electromyographic activation patterns of the elevator muscles of the jaw. One particularly contentious area of enquiry is whether it is facial morphology that determines the strength of muscle activation, or whether a strong musculature can influence skeletal growth processes.

In light of the aforementioned considerations, the objective of the current clinical observational study was to investigate the potential correlation between the electromyographic activity of selected masticatory muscles (masseter, anterior temporalis and suprahyoid) and the craniofacial morphology of subjects under examination, with a particular focus on elucidating the mechanical advantage derived from different sagittal relationships between the maxillae. The electromyographic evaluation is carried out before the beginning of the orthodontic treatment (T0).

Interventions

DIAGNOSTIC_TEST

EMG

Disposable bipolar surface electrodes will be used. The patient's skin will be clean with cotton gauze soaked in alcohol before electrodes placement to reduce skin impedance. The operator will palpate the muscle belly while the patient clenches his teeth and will position surface electrodes in parallel to the muscular fibres. Doing so the position of the electrodes results as follows: Masseters electrodes will be fixed parallel to the exocanthion-gonion line and with the upper pole of the electrode under the tragus-labial commissural line. Temporalis electrodes will be positioned along the anterior margin of the muscle (corresponding to the frontoparietal suture). Suprahyoid muscles electrodes will be placed in the submental area nearly 1 cm posterior to the mental symphysis, paramedian to the midline and lightly diverging. A reference electrode will be applied to the forehead of the patient.
