Abstract:
OBJECTIVETo analyze the relationships between MRI image changes of lateral pterygoid muscle (LPM), disc position and condylar mobility.
METHODSTwenty Class II 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.
RESULTSThe rate of MRI image changes of LPM in Class II patients was about 45%. No significant correlations were found between MRI image changes of LPM, condylar mobility and disc position.
CONCLUSIONSMRI image changes of LPM in Class II patients was common but no significant correlations were found between MRI image changes of LPM, condylar mobility and disc position.
