ABSTRACT

The aim of this study is to investigate the stability of the results obtained through functional orthodontic treatments after the retention period in skeletal class 2 cases. 14 subjects having skeletal class 2 structures with a skeletal age of approximately 11 years were examined. 7 out of 14 were separated as treatment group, where the other 7 were separated as the control group. Contantion treatment was performed to the treatment group, for a period of 2 years in average, which have been treated with activators for approximately 1 year. The cephalometric radiographs of all subjects were taken at the beginning and the end of treatment and retention. The measurements relating to cephalometric tracing were statistically evaluated.
