Abstract
With the development of orthodontics and increasing concerns on physical appearance, the number of patients has been steadily increasing. It is quite important not only to make effective cure plans and accurate diagnoses but also to have a thorough grasp of patients’ malocclusion types and their occurrence frequency, in addition to patients’ personality in order to cure the patients appropriately.
This study is based on 946 malocclusion patients who had visited Chong-A Dental Hospital from 1999 to 2004 and investigated their aspects of malocclusion and characteristics of their gender, age and residence. The results are as follows.
1. The number of patients per year had been decreased until 2001, after which year the number had fluctuated. The number was the largest in 1999, 169 and the smallest in 2001, 140. Female occupied 68.0% of the total, twice as many as male, 32.0%)
2. Based on the Angle’s classification, 19 or over year - old group was the largest of the total, 59.3% and 6 or younger year - old group, the smallest, 0.5%. The 19 or over year old group was less than a half of the total (47.4%) in 2003 and there were no patients who belonged to the 6 or younger year - old group in 2003 and 2004.
3. Distributions on the types of malocclusion have shown that 39.9 % of the total are in the Class
I, the largest, 31.0% in the Class and 29.2 in the Class , the smallest.
1) The number of the ClassI was 73, the largest, that of the Class being 35, the smallest in
1999. On the whole, the number of the Class accounted for the largest part of the total.
2) The number of male patients in the Class was the smallest, generally being the largest in the
Class . In case of female, that of the Class was the smallest.
3) Based on the age, the Class was the highest in between 7 and 13 age group, the Class the
lowest. The Class occupied the largest around 40%.
4) In the shape of physiognomy, the meso occupied the largest part among all the Class, of which the Class was the highest, 64.2%. The bracy was the largest in the Class , and the dolicho
in the Class.
5) In the profile, the convex shape was the largest in the Class and , and especially in the
Class , over 3/4 of the total, 75.4%. In contrast, the direct shape was the largest in the Class
and the sunken shape occupied 33.3%, which was nearly ten times more than the case of
the Class and.
6) In the asymmetry of physiognomy, the number of patients of the Class was the largest,
34.1% and that of the Class , the smallest, 19.5%. It was found that about one fourth of the
malocclusion patients were under the asymmetry of physiognomy.
4. In the distribution of patients’ residence, 81.4% were from the Seoul Metropolis and 48.2%
from Gangnam-Gu where Chong-A Dental Hospital is located and Seocho-Gu and Songpa-Gu
