Abstract 1

Surface Electromyography (sEMG) is particularly indicated in neuromuscular occlusion assessments as it allows for a global and simultaneous analysis of different muscles, in a physiological mandibular resting position (mandibular posture) and/or during mouth closure and occlusion (habitual or corrected).

The authors aim to present the protocol for recording and analyzing muscle activity using electromyography, as practiced in the Occlusodontology and Functional Rehabilitation of the Masticatory System Unit at CHU Rangueil (Toulouse) and in ICCMO French section. The presented methodology refers to the MAC (Muscular Activity Protocol) and can be supplemented by an electronic recording of mandibular kinematics (MAC, Mandibular Kinematics Protocol)

Abstract 2

After studying muscle activity using surface electromyography (sEMG), the next step is to analyze certain mandibular movements in the three spatial planes and over time. Initially, this involves successively examining mandibular posture (rest position), habitual dental occlusion, and swallowing.

In the second phase, recording the amplitude of mandibular movements (opening/closing, laterality, and propulsion) and the velocity of the opening/closing movement provides additional information to the clinical examination. These movements can be recorded simultaneously with the EMG activity of the orofacial muscles.

The presented methodology refers to the MAC Protocol (Mandibular Kinematics Protocol) (1).
