Title Advantages Of Self-Ligating Bracket Systems
Clinical Question Are self-ligating bracket systems truly an improvement in orthodontic treatment when compared to conventional edgewise bracket systems?
Clinical Bottom Line Orthodontic treatment objectives can be successfully attained regardless of bracket system used. Diagnosis and treatment planning with competent execution of treatment is more important than any specific bracket system used in treating the orthodontic patient. (See Comments on the CAT below)

(level of evidence)
#1) 20685517Chen/2010Sixteen studies were reviewed, including 2 randomized controlled trials with low risk of bias, 10 cohort studies with moderate risk of bias, and 4 cross-sectional studies with moderate to high risk of biasSystematic review with meta-analysis
Key resultsThere are many claims stating the superiority of self-ligating bracket systems over conventional bracket systems. Although supporting evidence is generally lacking to support these claims, several recent studies have found a small but statistically significant difference in mandibular incisor position. These studies have found 1.5 degrees less mandibular incisor proclination with self ligating brackets compared with conventional bracket systems. No other supporting evidence regarding treatment time or occlusal characteristics after treatment has been found.

Comments on
The Evidence
The exclusion of certain studies from this systematic review due to a high risk of bias appears to be subjective in approach. This subjective exclusion of certain studies will result in a conclusion where not one bracket system favors another, thus allowing this study to be non-committal in its results.
Applicability A competent orthodontist is a greater predictor in achieving optimal results in treatment rather than using a specific bracket system over another.
