Accuracy of Computer-Aided Full Tray vs Computer-Aided Sectional Tray in Indirect Bonding of Orthodontic Brackets; A Randomized Clinical Trial

Abstract

Indirect bonding is considered to be a marvelous advancement in orthodontics over the last decade. It is of great use to the orthodontist through reducing chair time, providing patient comfort, and improving bracket placement accuracy. Precise bracket positioning is of great importance in efficient biomechanics application and in expressing the full potential of a preadjusted edgewise appliance, as well as providing less chair side time. Many researchers have tried their methods to accomplish indirect bonding by changing their ways during clinical or laboratory procedures. Also many studies have been conducted in order to test the indirect technique effectiveness. Actually, only few reports assessed the clinical reliability of the computer aided indirect bonding techniques either through complete trays compared with sectional trays, In this study we evaluated the accuracy of the transfer tray in both complete computer aided trays and sectional computer-aided trays, 20 participants were enrolled in this study from the out-patient clinic of the Orthodontic Department of the Faculty of Dentistry Ain-Shams University and were randomly allocated in two groups. Measurements in six positional discrepancies (Mesio-distal, Occlusogingival, Buccolingual, Rotation, Tip, and Torque) were calculated and pre-transfer vs post-transfer data were compared digitally.
