مع ازدياد عدد المرضى البالغين الذين يبحثون عن المعالجة التقويمية أصبحت الحاجة لتامين قوة ارتباط كافية لعناصر الجهاز التقويمي الثابت على الترميمات الخزفية أمراً ملحاً وبما أن السطوح الخزفية هي سطوح خاملة كيمياً كان من الصعب تحقيق ارتباط كيميائي بينها وبين مادة الإلصاق الأمر الذي جعل تهيئة السطح الخزفي قبل إصاق الحاصرة التقويمية خطوة أساسية لا غنى عنها .
With the increase in the number of adult patients seeking orthodontic treatment, the need to ensure sufficient bonding strength for the fixed orthodontic components on the ceramic restorations has become an urgent matter. Adhesion of the orthodontic bracket is an essential and indispensable step.

Since the solution of direct bonding of orthodontic brackets as an alternative to full encircling of the dental arch, researchers have begun conducting studies to evaluate the adhesion materials and different methods of enamel preparation to reach the most appropriate method for the requirements of ideal adhesion.
The laser has been used as an alternative effective method of etching enamel surface for direct bonding of orthodontic brackets instead of phosphoric acid. The aim of this study was to compare shear bond strength of orthodontic brackets following Er-
Background
Resin bonded fixed partial dentures appeared to prevent the excessive preparation of dental
tissue
Investigation of surface treatments to improve the bond of resin cements to metals may contribute
to the longevity of these restoration
The aim of this study To compare in vitro shear bond strength (SBS) of different
orthodontic adhesives in and rebonding metal brackets after preparing their bases
mechanically.
Material and methods:Sample consisted of 40 extracted first premolars,
This study aimed to compare the effects of different enamel
etching techniques for bracket bonding strength. The sample
consisted of eighty human premolars were randomly divided into
four equal groups. The enamel surfaces of the teeth were etched
