Abstract:
0.05). In amount of mandibular set back, we found the condylar hange(T2-T1) which had increased tendency from Group 1 to Group 3 and decreased tendency of MM' from Group 1 to 3. but there was no statistical significance (p>0.05). There was some correlation between condylar change and TMJ dysfuction. It seemed that postoperative condylar change had influenced the postoperative TMJ dysfunction, though was no statistical significance (p>0.05). As we have observed the change of condylar axis in the group that complained of TMJ dysfunction after operation in cases of large amount of mandibular set back, do we consider that the more trying to onserve the condylar position will decrease the occurrence rates of the postoperative condylar displacement, TMJ dysfunction and the relapse.]]>
