Abstract: Objective To analyze the relationships between MRI image changes of lateral pterygoid muscle (LPM) , disc position and condylar mobility. Methods Twenty Class Ⅱ1 patients were chosen and MRI images of LPM were taken. The relationships between MRI image changes of LPM, disc position and condylar mobility were analyzed. Results The rate of MRI image changes of LPM in Class Ⅱ1 patients was about 45%. No significant correlations were found between MRI image changes of LPM, condylar mobility and disc position. Conclusions MRI image changes of LPM in Class Ⅱ1 patients was common hut no significant correlations were found between MRI image changes of LPM, condylar mobility and disc position.
