Abstract

Thirty patients who visited our hospital with a chief complaint of mismatched dentures and were subsequently diagnosed as class C 1 according to Eichner's classification (mean age: 66.6 years) were the subjects. The oral cavity of each patient was examined. In addition, questions were asked and X-rays and MRI were taken to investigate the relationship between disc displacement and factors such as condyle position and the state of the oral cavity.<BR>Fisher's exact probability test and multivariate analysis utilizing Hayashi's quantification theory were applied for statistical analysis.<BR>The results were as follows:<BR>1. MRI imaging revealed disc displacement in 20 joints of 13 patients (43.3%).<BR>2. Condylar bone changes were seen in 11 joints of 8 patients.<BR>3. A lateral or bilateral posterior shift of the condyle position was seen in 54% of the patients with disc displacement.<BR>4. Statistical analysis revealed significant difference in the type of artificial teeth, deviations in the opening and closing movements of the mouth, past history of temporomandibular arthrosis, and joint click between the patients with disc displacement and healthy individuals.<BR>5. The presence of disc displacement most strongly correlated with the past history of temporomandibular arthrosis, followed by deviations in the opening and closing movements of the mouth.
