Many patients who present for orthodontic corrections have some form of temporomandibular joint dysfunction (TMJD). These problems can extend from rather simple to extremely complex. The most difficult category includes those patients with internal joint derangement. Patients with dislocated non-recapturable temporomandibular joint (TMJ) are provided a new method of treatment. Mitek Anchor Surgery: Orthodontic patients are evaluated to determine whether they posses signs and symptoms of TMJD, or do they have normal joints. A joint is normal when the following characteristics exist: Painless, noiseless, full range of motion, and without deviation or deflection. A normal patient is generally free of headaches, neckaches, earaches, facial or joint pain.
The condyle should contact the central avascular portion of the disc which should function against the anterior slope of the eminence. There should be a consistent contact of these structures in all movements without any displacement or dislocation of the disk. The joint structure should be supported by normal muscle function with a Class I mutually protected occlusion.
