Characteristics of masticatory behavior of patients with mandibular prognathism.

Background: Patients with mandibular prognathism exhibit not only its characteristic maxillofacial morphology but also discrepancies in stomatognathic function, and understanding this morphology and function is vital for establishing a plan for surgical orthodontic treatment or providing guidance for recovery after orthognathic surgery. However, few studies have yet addressed the objective evaluation of masticatory function before and after surgical orthodontic treatment. In particular, the masticatory behaviors that show how you chew in your daily meals, including the number of chews, chewing rate, and posture during chewing, has not yet been fully studied in patients with mandibular prognathism.
