Comparative Evaluation Of Shear Bond Strength Of Monocrystalline And Polycrystalline Ceramic Brackets Using Two Different Bonding Systems On Two Different Cad/Cam Materials : An In-Vitro Study

Abstract

Introduction: Adult patients seeking orthodontic treatment have increased significantly in the last decade. Inspite of the emergence of Invisalign, a large group of adult patients still favor ceramic brackets as choice for esthetic orthodontic treatment. With the increase in age, patients may require certain crowns and dental restorations in addition to orthodontic therapy. With the emergence of CAD/CAM in dentistry, single tooth crown restorations may now be made both chairside and in the lab. So, it has become very important for orthodontist to find a proper bonding protocol which gives optimal bond strength to bond metal and ceramic brackets to the newer CAD/CAM materials. The aim of the study was to to evaluate the SBS of monocrystalline and polycrystalline ceramic brackets on different CAD/CAM materials using two different bonding agents.
