Autorotation of the Mandible: A Truth or a Myth—A Review

Autorotation of the mandible plays a pivotal role in various aspects of jaw function and biomechanics. As the lower jaw rotates, it not only facilitates chewing and speech but also contributes significantly to maintaining proper occlusion and dental health. Autorotation is intricately linked with the temporomandibular joint (TMJ), allowing for smooth and coordinated movement during mastication and other oral activities. Understanding the dynamics of autorotation is crucial in diagnosing and treating conditions such as temporomandibular disorders (TMDs), where disruptions in mandibular movement can lead to discomfort and dysfunction. Autorotation of the mandible underscores the complexity of the craniofacial system and its interaction with surrounding structures. Advancements in biomechanical research have shed light on the nuances of mandibular autorotation, aiding in the development of therapeutic interventions and orthodontic treatments aimed at restoring optimal jaw function. This review helps in understanding of mandibular growth pattern and associated growth rotation. It also focuses on various predict methods of autorotation of mandible following Lefort 1 for achieving the desired treatment goals.
