Abstract:
Objectives: To investigate the occlusion features in thre e dimensions in patients with temporomandibular disorders(TMD). Methods: Occlusal casts were obtained from 23 asymptom volunteers and 101 TMD pati ents and were analyzed in three dimensions by scores vertically, mesio-distally and labial-or buccal-lingually. Bilateral TMJs of each TMD patient was examin ed with Schuller's radiograph and tomograph, the sounding TMJs were examined wit h arthrography. The relationship between occlusion scores and the changes shown in X-ray images were analyzed. Results: 66.3% TMD patients had abnormal occlusion in vertical direction.Abnormal occlusion in vertical directio n was correlated with TMD symptoms(P 0.05 ). Conclusion: Abnormal occlus ion in vertical direction is correlated with TMD symptoms.
