Review finds that orthodontic treatment using self-ligated bracket systems take longer than conventional approaches


This review aims to assess the role of the various characteristics of orthodontic brackets (material, slot size, ligation type, etc) and their combination with specific wires on their clinical effectiveness and associated side-effects during fixed-appliance orthodontic treatment. Searches were conducted in Medline, Cochrane Library, Biomed Central, BBO including LILACS, Ind Med, Sceilo, Clinical trials.gov, Conference [read the full story…]

To produce alignment without extraction. It has been suggested that passive self-ligating brackets can introduce specific, uniquely stable arch dimensional changes. The aim of this trial was to quantify maxillary arch dimensional changes and maxillary incisor and molar inclination changes during orthodontic alignment by directly comparing a passive self-ligating bracket, an active self-ligating system and [read the full story…]
