Abstract
|
|
|
The purpose of this study is to obtain the horizontal magnificatin rate of orthopantomography.
The subjects were consisted of 30 Kroean adults who had Angle´s classification I occlusion by using measuring wire set on the inclisal edges of anterior teeth and the occlusal surfaces of premolars and molars along the dental arch.
The results are as follows;
1. The average rate of total magnification was 115%.
2. The average rates of locl magnification were the anterior teeth region was 90%, the canine region was 96%, the premolar region was 104%, the 1st molar region was 117% and the 2nd molar region was 124%.
