Abstract

The advantages and disadvantages of Activa self-ligating brackets ("A" Company, San Diego, Calif.) are discussed in the light of extensive clinical experience and the currently available data concerning frictional forces between arch wires and these brackets. Detailed practical recommendations are made concerning the problems that are encountered. The principal clinical advantages arise from the unusual combination of very low friction and excellent control of arch wire engagement. The potential benefits are the rapid alignment of very irregular teeth, lower anchorage requirements, and facilitation of sliding mechanics. Several problems arise from the unfamiliarity of a bracket without tie-wings, but the most significant drawback is the bond failure rate which is currently higher than with conventional brackets from the same manufacturer.
