[To probe into the practicability of using the jaw position of eliminating TMJ clicks as the therapeutic position of repositioning splint].
OBJECTIVE
To evaluate that it was practicable to use the jaw position of eliminating TMJ clicks as the therapeutic position of repositioning splint and to probe into the therapeutic mechanism of repositioning splint.


METHODS
25 patients with reducible disc displacement were treated with repositioning splint. The therapeutic jaw position was the position without TMJ clicking, then verified by Arthrography. The treatment effect was observed.


RESULTS
Among 25 cases, 19 discs were completely recaptured, 5 incompletely recaptured, 1 not recaptured. Once the splints inserted, the movements of disc-condyle complex were smooth. After treatment finished, the opening types were improved, the clicks were lessened.


CONCLUSIONS
It's practicable to use the jaw position of eliminating clicks as the treatment jaw position of repositioning splint. The therapeutic mechanism of repositioning splint may be that it altered the relationship of disc and condyle and improved their movement. That was favorable to fibrize the retrodiscal tissue and to strengthen the posterior band of disc.
