Conservative reduction by lever action of chronic bilateral mandibular condyle dislocation.
OBJECTIVE
The treatment of long-standing dislocation of the temporomandibular joint is broadly classified into open reduction and closed reduction. The current study presents a case of long-standing dislocation of the temporomandibular joint treated 3 years after dislocation. In this study, the authors evaluated the long-term outcome of conservative reduction by lever action of chronic bilateral mandibular condyle dislocation.


METHODS
Manual repositioning of temporomandibular joint dislocation lasting for 3 years in a 31-year-old woman was attempted without success; therefore, conservative reduction by lever action was carried out because the patient declined treatment under general anesthesia.


RESULTS
The treatment was discontinued after 6 days because of the subluxation of the retaining tooth. The retainer was changed from tooth to screw for intermaxillary fixation, and treatment was reinstituted. Fifteen days later, reduction was achieved and retention was started and continued for 2 months. The outcome was good, with no recurrent dislocation within 24 months of the treatment.


CONCLUSIONS
Conservative reduction by lever action, involving minimally invasive treatment and little dysfunction, should be considered an optional conservative treatment.
