Popis: Introduction: The pre-adjusted brackets are available in various prescriptions and sizes; nevertheless there are still many controversies as to which pre-adjusted edgewise bracket offers the maximum clinical efficiency. Aim: This study was conducted to determine and compare the amount of lower incisor proclination during de-crowding if any of the Mini-Uni Twin Brackets with that of the standard double width brackets. Materials and Methods: A total of 20 patients i.e., 10 patients in each group both males and females were randomly selected for the study from subjects seeking treatment, the selected samples were grouped as follows. Group I – Double Width Brackets (3M Unitek Gemini Series) 0.018” slot with Roth prescription. Group II – Mini Uni-Twin Bracket (3M Unitek) 0.018” slot with Roth prescription. Results: The Mini-Uni Twin Brackets had statistically significant (p = 0.01) amount of proclination of the lower anteriors (0.8o± 0.3o) after de-crowding as compared to the standard Double Width Brackets and since the mean change in the Incisor Mandibular Plane Angle (IMPA) was lesser than 1o, its clinical significance could be questionable. Conclusion: The Mini Uni Twin brackets are comparatively efficient in the lower anterior decrowding but further comparative clinical studies need to be performed on these Mini Uni Twin brackets, with an increase in the sample size and also the number of parameters to prove its total clinical efficiency.
