乳齒列期 兒童의 顎顔面軟組織의 頭部放射線 計測學的 硏究 = (A) roentgenocephalometric study of soft tissue profile for the children in the deciduous dentition

다국어 초록 (Multilingual Abstract)

This study was made on the facial profile of the normal Korean children using the roentgenographic cephalograms. The subjects consisted 51 males and 47 females children of primary dentition with the normal occlusion and acceptable profile. For this study 13 soft tissue profile landmarks were plotted and 14 liner length, 9 soft tissue thickness, 8 vertical height length, 12 angles of soft tissue profile, and 2 vertical proportion were measured. The mean and standard deviations in the subjects were calculated and compared between male and female.
The following results were obtained :
1. By the significant test, total facial convexity angle and soft tissue thickness were no significant difference between both sexes.
2. Lower facial height was greater than upper facial height in both sexes.
3. The vertical length of the upper and lower lips were 21.95㎜, 40.74㎜ in male and 21.62㎜, 39.63㎜ in female.
4. In the relationship of the upper lip and lower lip to the Ricketts esthetic line, the male was 1.3㎜, 1.18㎜ and the female and the female was 1.16㎜, 1.27㎜ front of the esthetic line.
5. Compared with the angulation of flush terminal plane group and mesial step group, the mesial step group was greater than the flush terminal plane group except the chin angle.
