초록
두경부 자세 및 혀, 설골의 위치와 두개안면골격간의 연관성을 알아보기 위해, 원광대학교 치과대학 재학생 중 선천적 두경부 이상이나 결손치가 없고 과거 교정 치료나 보철치료의 경험이 없는 남자 50명과 여자 40명을 대상으로 natural head position(NHP)상태에서 두부방사선 사진을 채득하여 전통적인 두개내 참고선과 두개의 진성 참고선을 이용하여 계속한 결과 다음과 같은 결론을 얻었다. 1. 두경부 자세변수들에서는 남녀간 차이가 없었으나, 설골의 위치는 남자가 여자에 비해 더 전하방에 위치하였으며, 더 큰 전하방 경사도를 보였다. 2. 경추의 경사도가 클수록 NHP에서 안면돌출도는 작게 나타났으며, 경추의 전방만곡이 증가할수록 수직적인 안모형태를 보였다. 3. 두경부각이 작을수록 두개저에 대하여 설골이 전방에 위치하였으며, 두경부각과 설골의 수직적인 위치는 연관성을 보이지 않았다. 4. 하악골이 전돌될수록 설골은 전방에 위치하였으며, 두개안면형태와 설골의 수직적인 위치는 미약한 연관성을 나타냈다.
The purpose of this study was to examine the associations of head posture the position of the tongue or the hyoid bone to craniofacial structure. Cephalograms taken in Natural head position(NHP) of 90 dental students (50 in male, 40 in female, 20 to 30 years in age) were traced and measured using the extracranial true horizontal and vertical lines. The obtained results were as follows; 1. There was no sex difference in head posture, but the hyoid bone was placed anteroinferiorly in male more than in female and anteroinferior inclination of the hyoid bone showed greatly in male. 2. The more inclined was the cervical column, the less prognathic was the face in natural head posture, and the larger cervical curvature, the more vertical pattern of the face. 3. The less small showed craniocervical angulation, the more anteriorly placed was the hyoid bone to the cranial base, and there was no significantly association between craniocervical angulation and the vertical position of the hyoid bone. 4. The more prognathic was the mandible, the more anteriorly placed was the hyoid bone, and there was slightly association between the craniofacial morphology and the vertical position of the hyoid bone.
