Intracapsular Problems
Eminence Click - results from the head of the condyle popping over the crest of the eminence.
Disk Movement (DM) - Results from the articular disk not being as stable as it should be.  This may be due to the laxity of one or more of the ligaments or tendons that function to hold the disk in its ideal position between the head of the condyle and the glenoid fossa.
Dislocated Disk (DD) - May be self-reducing, also known as auto-reducing (DDR).  A dislocated disk may be associated with a clicking or popping with movement of the mandible.  It may also be non-reducing in which case it may be quiet and without vibration and/or limit the range of motion of the mandible.  A non-reducing DD also may not limit the range of motion of the mandible if the ligaments have been stretched.  In this case the condition is usually associated with a disk that has been dislocated for a significant period of time.
Dislocated Disk with Degenerative Joint Disease (DD/DJD) - This condition could be self-reducing (DDR/DJD).  It may also be non-reducing with either early or advanced degenerative joint disease.
