초록

The aim of this study was to investigate clinical and cephalometric characteristics of patients with anterior open bite and mandibular condylar resorption. Total of 45 subjects were recruited from the patients who visited the Department of Oral Medicine, Kyungpook National University Hospital in 2006 for treatment of temporomandibular dysfunction. After taking patient's history concerning temporomandibular joint dysfunction, clinical examination was performed and panoramic, transcranial, and lateral cephalometric radiographs were obtained. The cephalometric data were compared to those of normal Korean population. The results were as follow: 1. Clinical characteristics 1) Female was 4.6 time more prevalent than male, and 82.2% of the subjects were in second and third decade. 2) Angle's Class I occlusal type was 51%, Class II was 29%, and Class III was 20%. 3) The mean value of the overjet and overbite were 3.2mm and -1.1mm, respectively. 4) Most of the patients had parafunctional oral habits. 2. Cephalometric characteristics 1) SNA showed no significant difference between condyle resorption and normal group. However, in female resorption group, SNB was lesser and ANB was greater than those in normal group. 2) SN-GoMe and FMA increased in resorption group. 3) Palatal plane angle did not show significant difference between resorption and normal group. 4) Total posterior facial height was significantly smaller and total anterior facial height showed no significant increase as compared with those of the normal group. 5) Mandibular body length did not show any significant difference between resorption and normal group.
