Mandibular Condyle Position in Maximum Mouth Opening: A Magnetic Resonance Imaging Evaluation

The purpose of this study was to analyze the condylar position in the maximum mouth opening in a group of individuals with and without temporomandibular joint disorders (TMD) using corrected magnetic resonance imaging (MRI). It was analyzed the MRIs of 200 temporomandibular joint (TMJ) of 100 adults...

It was analyzed the MRIs of 200 temporomandibular joint (TMJ) of 100 adults (25 males and 75 females).
