Aim: This study is aimed to evaluate the efficacy of modified stabilizing splint in reduction anteriorly displaced disc in patients with bruxism.   Patient & Methods: This study was carried out on 26 patients, (14 femal&12male) .Patients complained of severe periauricular pain, inability of eating food, loudly unilateral clicking and se- vere temporal headache. Tenderness of masseter and temporalis muscles on palpation. All patients underwent unilateral arthrocentesis and delivered with modified stabilizing splint with posterior open bite 6, 4, 2 mm, two weeks for each consecutive posterior open bite.MRI was done for each patient preoperative, one and 12months postoperatively. Follow up period was one year.   Results: All patients showed relief of periauricular pain, no clicking in (18 patients). Percep- tible clicking in (8patients). MRI revealed recapture of the anteriorly displaced disc on the condyle in closed &opened positions postoperatively, while anteriorly displaced deformed disc remained in position postoperatively in (8 patients) . Conclusion: Arthrocentesis and modified stabilizing splint are effective in recapture of the anteriorly displaced non deformed disc on the condyle in patients with bruxism.
