영문 초록

It has been known that class Ⅲ malocclusion has various etiologic factors and characteristic maxillomandibular and dental relation. The treatment of class Ⅲ malocclusion is divied two type by treatment timing: early orthopedic treatment and late surgico-orthodontic treatment. Nowadays, it is popular for the surgerns to use the combination of orthodontic treatment and orthognatic surgery. To study the timing of treatment of growing skeletal class Ⅲ children, we selected normal 30 male, 30 female children and skeletal class Ⅲ 15 male children, 15 female children and skeletal Ⅲ 29 adult male, 29 adult female. Cephalometric radiograph was treated by single investigator and maxillary, mandibular length was measured. The results were as follows; 1. The maxillary length of normal group in both children and adults were larger than malocclusion group in statistically level (p<0.001). 2. The mandibular length class Ⅲ malocclusion group in female children and adult is larger than normal group in statistically significant level (adult: p<0.01, female children: p<0.001). 3. Max/mand. ratio were 0.73 in class Ⅲ male children, 0.71 in female children and 0.66 in class Ⅲ male adult 0.67 in class Ⅲ feamle. 4. Difference of maxillary and mandibular length were 29.06mm in class Ⅲ male children, 29.96mm in female children and 47.19 mm in class Ⅲ male adult, 42.06 mm in class Ⅲ female adult.
