-Abstract-
The purpose of this study was to obtain the data on the maxillofacial growth changes
of the Korean six-year-old children in a year to establish the maxillofacial growth
prediction model. Dental arch stone models of the 682 students in 1995 and of the same
students in 1996 were analysed. The maxillofacial growth changes of the students
during one year were found by the analysing the dental arch stone models.
The dental arch growth changes in a year were analysed by student t-test and the
qunantigty of growth per a year of dental arch lengths and widths by paired-test. The
obtained result were as follows:
1. It was found that all dental arch lengths and widths had grown during one year.
2. There is no difference between male and female students in maxillofacial growth
changes.
3. Maxilla had grown a little more than Mandible during one year
4. Dental arch lengths had grown a little more than dental arch widths during one year
