Abstract
The patient was 18 years old female with chief complaint of intermittent closed lock, sound and pain on opening movement on left temporomandibular joint (TMJ), especially rising. Though her maximum opening range of jaw opening was limited less than 27mm, she was able to normal opening when she was made eccentric jaw opening movement. In the MRI view in which both side TMJ were anterior disk displacement with reduction. Based on axiograph view, we considered that click-ing during mouth closing occurred in the mandibular position in which the displaced disc returned to the normal position on the chondyle, as we called therapeutic reference position (TRP), and per-formed therapy of using functional appliance. After the elimination of the clinical symptom is confirmed, as clicking, sound and pain during jaw movement, the occlusal reconstruction was per-formed by using the three dimensional control of tooth which multi-bracket method for TRP jointly with the functional appliance. The reconstructed occlusion was obtained with disappearance of all clinical symptoms passed after 2 years of post retention.
Therefore, it is possible that the therapy of occlusal reconstitution using the technique of orthodontics was an effective treatment for the anterior disc displacement with reduction case.
