EVALUATION OF THE EFFECTS OF SELF-LIGATING BRACKETS ON THE ORTHODONTIC TOOTH MOVEMENT

Objective: The aim of this study was to compare effect on tooth movement and rate of canine distalization accomplish with self-ligating brackets (Gemini SL) and conventional brackets (Gemini).
Methods: Self-ligating brackets group (SLB) (18 individuals) and control group (CONT) (15 individuals) were created with cases who need fixed orthodontic treatment with exraction of first premolar in this study. Canine distalization was performed on 0.019×0.025 inch stainless steel wire using nickel-titanium (NiTi) closed coils that applied approximate force of 150 gr after levelling and aligning. Plaster models and photographic recordings were taken at the 1st, 4th and 8th weeks of distalization. The resulting plaster models were scanned with three-dimensional scanning device. The amount of canine distalization, canine distopalatinal rotation, canine tipping, molar mesialization and extraction spaces were measured.
Results: While there was no statistically significant difference in terms of can
ine distalization, distopalatal rotation, tipping and extraction space in the maxilla, a significant difference was observed in molar mesialization. Different from the maxilla, there was a significant difference in canine tipping values in the mandibula.
Conclusion: There was no difference in rate of orthodontic tooth movement between self-ligating brackets and conventional brackets.
