[Effect of cervical headgear therapy on point B in class II, division 1 cases].
The aim of this study is to evaluate the effect of cervical headgear on point B. The study depends on 40 lateral cephalometric films of 20 cases. 10 Class II, 1 cases had undergone cervical headgear therapy (Treatment group) and 10 Class II, 1 cases had received no treatment (Control group). 4 angular and 5 linear measurements were made on the films. By comparing the treatment and control groups, the changes related to growth was eliminated and the following results were obtained; According to SNB angle there was a statistically significant (p less than 0.05) difference between the two groups. SNB angle increased more in the treatment group. But in a measurement which was made to see the linear difference on point B, there wasn't any statistically significant difference between the two groups.
