The purpose of this study was giving some helpful datas in analysing the degree
of anteroposterior jaw disharmony with the "Wits" appraisal.
The cephalograms of 105 Korean adults with normal occlusion ranging from 17 to 20
years of age and 76 Koreans with various malocclusion ranging from 12 to 24 years
of age were studied and analyzed statistically
The results were as follows :
1. The mean value of "Wits" appraisal in normal occlusion group was -0.82 mm in
males and -0.17 mm in females.
2. There was no significant difference between the males and females in normal
occlusion group.
3. The mean value of "Wits" appraisal in Angle class Ⅱ malocclusion group was
2.67 mm and higher than normal group.
4. The mean value of "Wits" appraisal in Angle class Ⅲ malocclusion group was
-8.11 mm and lower than normal group.
