The aim of the study is to evaluate the occlusion time is prolonged in patients with TMJ internal derangement (TMJ ID) as compared to healthy control subjects. Materials and Methods: Subjects with full dentition and angle class I relation. DC/TMD criteria was used to diagnose the patients, the occlusion time OT registered in the maximum intercuspation digitally by using T-Scan NOVUS device. Results: Non-significant differences between the age groups, disc displacement with reduction is the more prevalent disorder. Highly significant differences between the participant’s genders and the female demonstrated the higher percentage of the TMJ ID patients. Highly significant difference in the occlusion time is reported between the TMJ ID patients and the healthy control. Conclusion: In this study, the Disc displacement with reduction is the more prevalent and females represent the higher percentage in having TMJ internal derangement. Prolonged occlusion time was reported in both healthy control and the patients with signs and symptoms of TMJ internal derangement. But it was higher in the TMJ ID patients with a significant difference. Regarding the different conditions of disc displacement, there were a non-significant difference in OT between them.
