Lateral segmental mandibulectomy can be associated with sequelae, such as mouth opening limitation and mandibular deviation, that lead to altered oral functions (chewing, swallowing, speech) and complex prosthetic management. The authors present a new protocol for surface electromyography (sEMG) and mandibular motion recording to help clinicians with decision-making and dental prosthetic treatment planning for segmental mandibulectomy. The clinical case of a patient with a reconstructed

During the orofacial reeducation and dental prosthetic reconstruction, three therapeutic steps can benefit from the MAC2 protocol: to analyze the initial muscular imbalance, to provide guidance in the choice of maxillomandibular relationship and to quantify the functional improvement. sEMG of masticatory muscles is a useful diagnostic tool in a context of mandibular kinematic disorders and the MAC2 protocol adds some guidance for dental prosthetic rehabilitation in the context of segmental mandibulectomy.
