- Primary Outcome Measures
Name Time Method Mobility in miniscrews. Timepoint: every 4 weeks after miniscrew placement. Method of measurement: By placing a calibrated probe on the miniscrew and lateral movement, if mobility is greater than 0.5 millimeter, the miniscrew is designated mobile.;Pain. Timepoint: immediately after miniscrew placement and 6hours, 24hours, 48hours, and a week after. Method of measurement: registeration of the amount of pain from 0 (minimum pain) to 10 (maximum pain) according to Visual Analogue Scale in special times.
- Secondary Outcome Measures
Name Time Method Amount of insertion torque of the miniscrews. Timepoint: during insertion of miniscrews. Method of measurement: Torque measurement device (Orthonia, JEIL Company).
