maxillofacial patient rehabilitation: how can we increase maximum interincisal opening in patients by surgical intervention?

Maximum interincisal opening (mio) refers to the greatest distance between the upper and lower incisors when the mouth is opened fully. it is a measure of the range of motion in the temporomandibular joint (tmj) and can provide insights into the function and health of the jaw. following maxillofacial surgery, patients frequently experience restricted mio for several reasons. effective rehabilitation is essential for restoring both functional and esthetic outcomes. normal mio values generally range between 40 to 60 millimeters in adults. however, this can vary based on individual anatomy and age. conditions leading to decreased mio include temporomandibular joint disorders, muscle disorders, dental issues, trauma, orthodontic issues, infections, and systemic conditions. if a decrease in mio is observed, it is often advisable to seek evaluation from a dental or medical professional to determine the underlying cause and appropriate treatment. this article discusses current strategies and advancements in the rehabilitation of mio in patients who have undergone maxillofacial procedures.
