저자는 Angle씨 제Ⅲ급 부정교합과 정상교합간의 두개 및 악안면 경조직의 상호 연관성의 차이점을 조사하기 위해 성인 제Ⅲ급 부정교합자 남녀 각 28명과 정상교합자 남자 35명, 여자 46명을 대상으로 두개저 실측거리 및 두개저에 대한 악안면 경조직 제 부위의

비율 등, 29개 항목을 계측 조사하였으며, 제Ⅲ급 부정교합을 정상범위의 SNA각 및 SNB각을 기준으로 남녀별 유형별 분류하여 다음의 결론을 얻었다.

1) 제Ⅲ급 부정교합에서 남녀 모두 두개저 실측치는 정상교합보다 작게 나타났다.

2) 제Ⅲ급 부정교합에서 남녀 모두 BN/ptm-A에서 정상교합보다 작았으나 유의차는 없었다.

3) 제Ⅲ급 부정교합에서 남녀 모두 ramal inclination, mandible inclination, BN/Go-Pog, lower gonial angle등이 정상교합에 비해 크게 나타났다.

4) 제Ⅲ급 부정교합에서 정상교합에 비해 상악전치는 순측경사, 하악전치는 설측경사되어 있었다.

5) 제Ⅲ급 부정교합의 유형별 분류에서 남녀 모두 상악골은 정상범위, 하악골은 전방돌출된 유형이 가장 많았다.



[영문]A COMPARATIVE STUDY ON CRANIOFACIAL SKELETON BETWEEN ANGLE'S

This is to investigate the difference between craniofacial correlation of Angle's class Ⅲ malocclusion and that of normal occlusion.

For this investigation, 28 adult males and famales, who have class Ⅲ malocclusion, and 35 adult males and 46 adult females, who have normal occlusion were selected to measure actual dimension of cranial base and to investigate ratio of various parts of maxillofacial skeleton against cranial base. Class Ⅲ

malocclusion were, also, classified based on SNA and SNB angle in normal range.

Results were as follows.

1. In class Ⅲ malocclusion, actual dimension of cranial base were appeared to be less than normal occlusion in both sex.

2. In class Ⅲ malocclusion, values were less than normal occlusion in BN/ptm-A in both sex but had no significance between two.

3. In class Ⅲ malocclusion, ramal inclination, mandible inclination, BN/Go-Pog, lower gonial angle were appeared to be greater. Thus, characteristic mandibular protrusive appearance of class Ⅲ malocclusion was due to relative ratio and morphologic characteristic of mandibular body dimension against cranial base.

4. In class Ⅲ malocclusion, upper incisors were labially tilted and lower incisors were lingually tilted compared to normal occlusion.

5. In typing of class Ⅲ malocclusion, the most common type was found to be one which maxillas were in normal range, while mandibles were in protrusive tendency.
