초록
This study was designed to get the knowledge of the structural characteristics of the lingual dental arch shapes of Koreans. The subjects consisted of 107 normal occlusions. The lingual structure which was divided into two groups, anterior and posterior part, was measured and analyzed. 33 pairs of the 107 samples were used to test the derived results. The findings of this study were as follows: 1. The mathmatical functions of the 12 curves which showed good fitting to the upper and lower anterior lingual arch were derived and flawed to the same scale using the computer graphics. 2. The results of the test showed a reasonable degree of accuracy to all of the 33 random samples. 3. The average degrees of posterior flexions were obtained and could be used as a initial guide at the wire-bending.
