Abstract: The conventional brackets, since the creation, have been modified in order to improve orthodontic mechanics and promote patient comfort. It is important to evaluate the anatomical and functional characteristics to understand what they represent as an advantage within treatment. There are hundreds of different types of conventional braces, but we don´t have the same market availability of lingual brackets. In Brazil there are seven brands of lingual braces available on the official market. All have very different characteristics, which doesn´t allow a similar way of working. The first brand sold in Brazil (ORMCO) was described, as well as the laboratory phase needed to validate the accuracy of brackets´ prescription due to the variability of lingual anatomy. Six other trademarks of same importance were reviewed. The seven lingual bracket brands were compared concerning to thickness, mesio-distal width of the bracket base and of the bracket body, interbracket distance, height and shape of the base, hooks, slot size and insertion, bracket prescription, need of laboratory phase, and if it has or not a bite plane on the anterior upper brackets. Clinical observations were performed in order to allow the professional to take advantage of what is best in each brand, indicating brackets according to the need of treatment mechanics.
