The aim of this study was to investigate clinical assessment, panorama & MRI findings and cephalometric characteristics in 42 patients with condylar resorption, who visited in the Department of Oral Medicine Kyungpook National University Hospital at 2006. The results were as follows; 1. Clinical assessment 1) Female was 34 and male was 8, females were predominant. Distribution of age showed as follows; 10s was 14, 20s was 13, 30s was 7, 40s was 3, 50s was 4 and 60s was 1 patient. 10s and 20s were predominant. 2) Most of the patients had parafunctional habit. 2. Findings of panorama & MRI 1) Most of the patients had degree of Grade II condylar resorption by panorama taking. 2) Most of the patients had disc dislocation and belonged to the degree of stage IV by MRI taking. 3. Cephalometric Characteristics 1) SN, SAr and saddle angle in female patients were significantly smaller and SN in male patients showed only significantly smaller than normal group. 2) SNA showed no difference from the normal group in both patients. SNB was smaller and ANB was lager in female patients than normal group. 3) SN-GoMe and FMA increased in patients. 4) Total posterior facial height & ramus height were significantly smaller. 5) Mandibular body length did not show any significant difference.
