The purpose of this study was to assess temporomandibular joint subluxation by
means of cephalometry using two lateral cephalograms from each person with in centric
occlusion and wide-open mouth position, and to compare patient group with subluxation
to normal control group in the measurements and correlation coefficient.
The 200 cephalograms of 100 Korean adults, patient group consisted of 24 females and
26 males ranged from 17 to 63 years age and the normal control group consisted of 20
females and 30 males ranged from 18 to 56 years age, were studied and analyzed
statistically.
The results ware as follows :
1. In the comparison of patient group vs. normal control group in the measurements,
statistically significant differences were found in C-C', C'-PTM, K-FH, K-PTM,
Gn-Gn', C-S-C', Gn-S-Gn', Gn-K-Gn', GoGn-SN, and GoGn-Go'Gn'.
2. K-points of patient group was located antero-superiorly than of normal control
group, and the significance level was higher in K-PTM than in K-FH.
3. There was no statistically significant difference found in local relationship of
C-point between patient group and normal control group.
4. The values of correlation coefficient among all measurements were in 0.958 r
-0.760, and the highest value was in Gn-Gn' to GoGn-Go'Gn' and Gn-K-Gn' to
Gn-Gn', and the lowest value was in C'-PTM to Gn-K-Gn' of normal control group. K
was determined as a point of intersection by a perpendicular bisector of Gn-Gn' and a
perpendicular bisector of C-C'.
