Abstract
The purpose of this study was to investigate the disclusion time and occlusal patter duri(?) lateral movement in normal group and temporomandibular dysfunction (TMD) group. Twe(??) dental college students of Chosun University without the abnormal occlusion (???) temporomandibular dysfunction were selected as a normal group, and twenty sligh(?) temporomandibular dysfunction (TMD) group and the ten moderate temporomandibu(?) dysfunction (TMD) group classified according to Helkimo’s dysfunction index were selection Occlusal pattern was classified as canine guided occlusion, group functioned occlusion and k(?0 other group during lateral movement and disclusion time in lateral movement was measured using T-Scan system. @ES The results were as follows: @EN 1. The disclusion time according to each group was 1.24±0.58 sec in normal group, 1.60±0.79 sec in slight TMD group and 2.29±0.80 sec in moderate TMD group. There was statistically significant between normal group and moderate TMD group(P<0.001) slight TMD group and moderate TMD group(P<0.05). 2. The distribution of occlusal pattern in normal group was 62.5% (25 side) in canine gi(?) occlusion, 27.5% (15 side) in group functioned occlusion. 3. The distribution of occlusal pattern in slight TMD group was 45% (18side) in canine gui(?) occlusion, 35% (14 side) in group functioned occlusion and 20% (8side) in other and (?) in moderate TMD group was 15% (3 side) in canine guided occlusion, 35% (7 side) group functioned occlusion and 50% (10 side) in other. 4. The disclusion time in normal group was 1.05±0.59 sec at canine guided occlusion (?) 1.53±0.72 sec at group functioned occlusion. 5. The disclusion time in slight TMD group was 1.23±0.75 sec in canine guided occlusi(?) 1.50±0.88 sec in group functioned occlusion, and 2.61±0.57 sec in the other. The was statistically significant between canine guided occlusion and other(P<0.001) and group functioned occlusion and the other )P<0.05). 6. The disclusion time in moderate TMD group was 1.28±0.84 sec in canine guided occh(?) 1.75±0.58 sec in group functioned occlusion, and 2.98±0.08 sec in the other (P<0.01).
