Orthodontic adhesives for fixed appliances: A review of available systems

Abstract

Achieving high bond strength of orthodontic brackets to enamel, and hence a low failure rate, are the basic demands for orthodontic bracket-bonding systems. Given that continuous replacements of loose brackets are clinically inefficient, time-consuming, and costly, the search for an ‘ideal orthodontic adhesive’ has been a hot topic for many years. Since a substantive number of studies have been focusing on brackets, adhesive systems, and enamel surface conditioning methods in recent years, the authors feel that a review article of this kind can be helpful for the busy clinician to update his/her knowledge about the various adhesive systems available on the market, supported by relevant evidence. CPD/Clinical Relevance: As there are no clinical guidelines currently in the literature for the selection of the ‘ideal orthodontic adhesive’ and the availability of a substantial number of materials, this review article might help clinicians in the selection process by presenting the available bonding materials, along with supporting evidence from the literature.
