Abstract

The aim of this study was to investigate clinical assessment and cephalometric characteristics in 10s patients with condylar resorption, who visited in the Department of Oral Medicine Kyungpook National University Hospital at 2006, by use of panorama, transcranial view and lateral cephalometric radiograph. The results were as follows; 1. Clinical assessment 1) Total number of patients were 59. Female was 47 and male was 12, Females were predominant and patient's age ranged from 12 to 19. 2) Most of the patients had Grade II condyle resorption. 3) The number of who had Class I occlusion was 27, which was the largest group. The number of patients with openbite was 20. Average overjet was 3.58mm and average overbite was 0.97mm. 4) Most of the patients had parafunctional habit. 5) The patients of showing the pain in condylar resortion was 41 and the case of not showing the pain was 18. 6) Treatment duration of 23 patients were less than 1 month, 28 patients were treated with supported therapy. 2. Cephalometric Characteristics 1) A 16-year-old female patients showed smaller SNA, SNB and larger articular angle significantly as compared with those of normal group. 2) A 17-year-old female patients showed smaller SN, SAr, TPFH, ramus height and larger SN-GoMe, FMA, articular angle significantly as compared with those of normal group. 3) Over 18 years old female patients showed smaller SN, SNB, TPFH, ramus height and larger ANB, FMA, SN-GoMe, LAFH, articular angle, gonial angle significantly as compared with those of normal group. 4) Over 18 years old male patients showed smaller SN, TPFH, ramus height and larger FMA, SN-GoMe, LAFH, articular angle, gonial angle significantly as compared with those of normal group. 5) There was no significant difference between 10s and normal group in mandibular body length.
