Average age of whole patients was 20.5 years. With regard to Angle classification, each percentage of Class I, Class II division 1, Class II division 2 and Class III malocclusion was 38.9%, 34.8%, 2.3% and 24.0%. The percentage of extraction cases (60.9%) outnumbered nonextraction cases (39.1%) and 46% of extraction cases were upper and lower 1st premolar extraction cases.
