Development of an in vivo ultrasound protocol to study the musculoaponeurotic architecture of the masseter during mandibular protrusion and lateral excursion

Temporomandibular disorders (TMDs) affect 5% to 12% of the population and lead to disability and pain. It has been suggested that architectural changes occur in the masseter muscle (MM) in TMDs. However, studies on normal in vivo MM architecture are scarce. Previously, our laboratory examined MM architectural changes during maximum intercuspation.
