The current evidence suggests no difference between the types of material s after 12 months but favours composite resin adhesives after a > 14-month period .
The clinical relevance of this study is that RM-GIC may have the same clinical debonding ( failure ) rate as composite resin adhesives after 1 year when used for bonding of orthodontic brackets
The aim of this systematic review was to establish whether the clinical debonding ( failure ) rates of orthodontic brackets bonded either with resin-modified glass ionomer ( RM-GIC ) or with composite resin adhesive  are the same .
A 12-month clinical evaluation of a light-activated glass polyalkenoate (ionomer) cement for the direct bonding of orthodontic brackets.
Glass polyalkenoate cements have the unique properties of physicochemically bonding to enamel and base metals and to leach fluoride over prolonged periods . These cements have been modified to provide a dual setting with both light activation and chemical cure to produce a more rapid set . This article reports a 12-month clinical trial of a light-activated glass polyalkenoate cement for the direct bonding of orthodontic brackets , compared with a st and ard composite bonding adhesive . There was no significant difference in failure rates of direct bonded orthodontic brackets cemented with Fuji II LC light-activated glass polyalkenoate cement ( GC Industrial Co. , Tokyo , Japan ) ( 3.3 % ) compared with System I+ composite bonding resin ( Ormco Corp. , Glendora , Calif. ) ( 1.6 % )
The current evidence suggests no difference between the types of material s after 12 months but favours composite resin adhesives after a > 14-month period .
