축추골 치아돌기의 형태 계측

Abstract

The odontold process of the ninety axis were measured to observe the morphological features m Koreans The results are as follows 1 Height of the odontiod process of axis was 14.1±1.3mm and the degree of the height of the odontold process to the height of axis was frequency of 38.2±2.6 % 2 Transverse diameter of odontold process of the most axis(87.8%) was thinner at the lower part than at the upper part And the difference of the thickness of upper part and lower part was 1.2±0.7mm In anteroposterior diameter lower part was thinner than upper part m frequency of 55.6% and the difference of upper part and lower part was 1.0±0.5mm in the transverse diameter 0.6±0.5mm in the anteroposterior diameter therefore the thickness of the anteroposterior diameter 3 The articular surface of the odontold process of the axis articulating with the antenor arch of atlas was 8.9±1.7mm m the maximal length and 7.1±1.6mm m the maximal breadth
