Hellman 치령ⅣA정상교합자의 두부방사선 규격사진에 의한 Template의 응용

The application of template constructed by cephalometric roentgenograms in Hellman dental age ⅣA with normal occlusion

The templates for male and female were constructed respectively by use of 36 male and 52 cephalometric roentgenograms in Hellman Dental Age IV A with normal occlusion. The grids were drawn to show 1 standard deviation and 2 standard deviation on every reference point. 1. When the template is used for cephalometric analysis, we con obtain comparatively accurate diagnosis even one or two refernces are distorted, decause several references are used for analysis. 2. The method of using the template is simple enough to perform cephalometric analysis easily. 3. If the templates are constructed for every age and sex, we can predict the growth patterns of the patients in the period of growth.
