Insufficient evidence to determine if orthodontic treatment is more or less efficient with self-ligating brackets than conventional brackets

This critical summary of a systematic review published in 2010 was prepared under the auspices of the American Dental Association Center for Evidence-Based Dentistry.

The aim of this review was  see whether  the use of using self-ligating brackets (SLBs)  improved clinical outcomes in orthodontic treatment compared with conventional brackets (CBs).

The commentator  noted that despite an extensive search  there were some reporting and methodological problems with the review along with  heterogeneity as a result of the variations of SLBs in use.

A range of outcomes were assessed but most were not directly related to treatment outcome or patient satisfaction. Overall  there  was limited evidence to support the use of one bracket type over another.
