목적: 본 연구의 목적은 한국인에서 스피만곡의 전형적인 형태와 성별, 연령, 좌우측에 따른 스피만곡을 분석하는 것이다. 연구 재료 및 방법: 콘빔형 단층촬영을 한 원광대학교 치과대학 산본치과병원 환자 중에서 본 연구의 기준에 합당한 500명(남자: 311, 여자: 189)의 이미지를 선정하였고, 스피만곡을 시상면 상에서 분석하였다. 결과: 한국에서 스피만곡 평균 반경은 91.4 mm였다. 스피만곡 반경의 성별에 의한 통계학적 유의성은 있었으나, 연령과 좌우간의 유의성은 보이지 않았다. 결론: 본 연구의 제한적 상황 내에서 몬슨에 의해서 주창되었던 101.6 mm보다 더 적은 한국인의 스피만곡의 반경은 특히 한국인에서 교합평면을 재건할 경우 모든 경우에서 스피만곡 수치를 그대로 적용하는 것을 재고해 볼 필요성을 제기한다.

Clinically, the curve of Spee is widely applied as a determined level of the occlusal curvature when the oral rehabilitation and the reconstruction of the prosthesis is needed at the malalignment dentition due to the missing, extrusion, and the inclination of the teeth. The purpose of this study was to analyze the curve of Spee of the occlusal curvature which influences to the occlusal form and the location three dimensionally, and then was to measure the radius and the degree of curvature of the curve of Spee and also was to investigate the influence to the cuspal inclination according to the change of the inclination of the curve of Spee which was analyzed by AutoCAD R.13 program at the gnathological cast and the cephalometric radiograph. The following results were obtained : 1. The radius of the curve of Spee was the mean of $11.74{\pm}3.64cm$ in the model, $12.75{\pm}4.63cm$ in the radiograph and there was no significant difference statistically between the model and the radiograph(P>0.001). 2. The radius and the degree of curvature of the curve of Spee showed negative correlation(r=-0.80), while the radius and the degree of curvature of the curve of Spee in relation to the length of the curve of Spee did not show correlation. 3. The case of the curve of Spee inclined to the posterior, that is. $Post.M{\theta}$ group showed the mean of $4.73{\pm}3.64$, positive correlation to the P2m, M1mm, M1dm, M2dm, and especially the greatest correlation coefficient to the mesial inclination angle of the mesio-buccal cusp tip of the first molar(r=0.70). 4. The case of the curve of Spee inclined to the anterior, that is, $Ant.M{\theta}$ group showed the mean of $3.28{\pm}3.59$, positive correlation to the P2m, M1mm, and also the greatest correlation coefficient to the mesial inclination angle of the mesio-buccal cusp tip of the first molar(r=0.78
