BackgroundAlthough a number of studies have been undertaken to evaluate the friction characteristics of self-ligating brackets, there have been only few studies which have actually evaluated the clinical efficiency of these self-ligating brackets. This study was done to evaluate the clinical efficiency of Passive SLB (Smart Clip) in terms of anchorage loss and total treatment duration by comparing it with a Conventional pre-adjusted edgewise (M.B.T.) bracket system.MethodsThis was a retrospective study in which the study sample comprised of ten patients treated with Passive SLB (Smart Clip, 0.022″) and ten patients treated with Conventional pre-adjusted edgewise (M.B.T.) bracket system (0.022″) who required therapeutic extraction of U/L first premolars as a part of their orthodontic treatment plan. Pretreatment and post treatment lateral cephalograms were taken to evaluate the amount of anchorage loss. The total time required to complete the treatment was also recorded.ResultsAnchorage loss observed with Passive SLB (Smart Clip) sagittally was 1.90 ± 0.68 mm in the maxilla and 1.90 ± 0.43 mm in the mandible and vertically was 0.52 ± 0.53 mm in the maxilla and 0.70 ± 0.69 mm in the mandible. Anchorage loss observed with Conventional pre-adjusted edgewise (M.B.T.) bracket system sagittally was 2.08 ± 0.43 mm in the maxilla and 1.95 ± 0.44 mm in the mandible and vertically was 0.50 ± 0.49 mm in the maxilla and 0.68 ± 0.53 mm in the mandible. The average time taken for the completion of treatment in Passive SLB (Smart Clip) and Conventional pre-adjusted edgewise (M.B.T.) bracket system was 14.0 ± 2.4 and 17.2 ± 2.6 months respectively.ConclusionThere was no statistically significant difference in the quantum of anchor loss between Smart Clip self-ligating bracket system and Conventional pre-adjusted edgewise (M.B.T.) bracket system although Smart Clip self-ligating bracket system is efficient in reducing the overall treatment time.
