The age differed between 10 to 13 No sex diffirence was made. Tracings were made on 96 before and after treatment cephalometric radiographs and linear dimensions were measured by using Coben Coordinate Analysis. The findings were evaluated by statistical methods. As a result, it was found that there was no difference between two techniques in treatment.
