The Butterfly System™ brackets feature a very low profile; yet also include a vertical slot fabricated into the brace for the addition of a variety of auxiliaries to enhance biomechanical versatility. The 16% reduction in profile dimension compared to typical pre-adjusted brackets improves their comfort because there is less of the brace to protrude from the surface of each tooth. As a result, they are much less obtrusive and potentially irritating than the bulkier, so-called “self-ligation” braces. In contrast to those larger braces, the Butterfly System™ emphasizes the “personalization” of a patient’s brace experience with a choice of multiple “colors” to tie in the wires! KO offers patients the choice of over 20+ different colors that can be mixed and matched to reflect school colors, sports teams, holidays, etc. Research from Ohio State University in 2010 reported that patients from 9-17 years of age still prefer the aesthetics of this style of orthodontic bracket where patients select the “colors,” compared to other brace alternatives.* In addition, the majority of orthodontists in the U.S. also prefer to use this style of orthodontic bracket (miniature twin pre-adjusted edgewise).
