Abstract

Purpose to review the clinical bond failure rate of adhesive precoated brackets (APC). Five online databases: PubMed, Scopus, Cochrane, EBSCO, and Web of Science were searched for potential eligible clinical trials. The correlated orthodontic articles and reference records were confirmed for all eligible studies. Two journal reviewers individually retrieved the data and evaluated the quality of the primary studies. A total of 146 articles were extracted in the initial search. However, only 13 articles met the inclusion criteria. Thirteen studies reported the failure rates using metal brackets for both APC and conventional systems. Three studies compared APC ceramic to conventional ceramic brackets. The result was inconclusive, there is no superiority of APC brackets over conventional bracket systems regarding the failure rate of the brackets.
