Distributions trends were examined in 9159 malocclusion patients had been examined
and diagnosed at Department of Orthodontics, College of Dentistry, Yonsei University
over a 6 year-period from 1992 to 1997. The results were as follows:
1. The total number of orthodontic patients in 1997 increased in comparing with that of
1992(86£¥)and after 1995, the number of annual patients showed an increase.
2. Age distribution had shown over-19 year-old group being the largest(39.9£¥) but
percentages of pre-adolescent patients had been decreasing while that of adult patient
had gradually increased.
3. Distributions in the types of malocclusion, the Angle's Classification had shown : 33.
3£¥for Class ¥°, 28.6£¥ for Class¥± and the largest 38.1£¥for Class ¥².
4. Among Class ¥°patients, crowding showed the largest(32.6£¥) and protrusion group
had gradually increased to 33.9£¥ in 1996. Otherwise openbite and groups tend to
decrease, annually.
5. Geographic distribution showed a majority of patients from Seoul(above 70£¥). Among
the patients from Seoul, group within the distance 3-6§° from Yonsei dental hospital
was the largest(32.3£¥) and group within 9§° showed 69£¥ of total patients.
