Contribution of Elecromyographic Examination to Neuro-Occlusal Rehabilitation

For Pedro Planas, the indirect tracks allow, in addition to the treatment of certain malocclusions, to release laterality movements and thus increase the activity of the masticatory muscles. The objective of this work will be to observe the effect of the Planas device on the activity of the masseter and temporal anterior, on each side, during right and left lateral movements. An electromyogram is used to assess the bioelectrical activity of these muscles with and without tracks in place. Figure 1: Plates with tracks or indirect tracks of Planas.

The electromyogram used for this work is a neuro bipolar EMG eb with: 1) Two dynamic recording channels and a frequency response of 20KHz during a 100 millisecond scan; 2) Integrated acoustic and visual stimulators; Figure 2: Neuro bipolar EMG eb. 3) Computer including all necessary software, hardware and accessories (Figure 2). The graphical recording of the anterior masseter and temporal muscles on both sides for each patient was obtained by means of self-adhesive electrodes fixed on the skin covering the muscles concerned, following the direction of the muscle fibers detected by palpation. The impedance at the passage of the current was reduced by a scrupulous cleaning of the cutaneous part used, with alcohol at 90 °. To obtain these recordings, each patient was asked to remove his orthodontic appliance and perform right and then left lateral movements (Figure 3). Figure 3: Self-adhesive electrodes. The same procedure was carried out for the recording of the electrical activity of the temporals and masseter during laterality movements, with the Planas apparatus installed. For all recordings, the patient was seated, with the Frankfurt plane almost parallel to the ground. In addition, efforts have been made to create an atmosphere of tranquility and silence. All recordings were made by the same neurologist. Results The computer provides a qualitative record of the frequency spectrum achieved by the patient’s muscles. The record obtained corresponds to the maximum power developed by the muscular system. In each patient who performs plate-free slippery laterality movements, a moderate increase in
