Accuracy In Transfer Of Orthodontic Bracket Positions: A Comparison Of Four Techniques Of Indirect Bonding

More and more orthodontists seem to be realizing the advantages of making indirect bonding a part of their clinical practice. With a multitude of techniques out there, it is important to have comparative studies to help make intelligent decisions about a choice of technique. Four techniques of Indirect Bonding namely RMBondRTMSingle Tray Technique, Glue Gun Tray technique, RMBondRTMDouble Tray Technique and EssixRTMDouble Tray Technique are compared to see if there are any differences among them in accurately transferring bracket positions in a simulated clinical setting. The initial bracket positions are measured first and then after the trays are fabricated and the brackets are bonded back on, the final measurements are done. These are then compared with the initial to evaluate the errors in the vertical, horizontal and angular dimensions. The results indicate that while all four techniques show negligent error in transferring bracket positions, there is a statistically significant difference between the groups among some of the variables. This difference, however is not clinically significant.
