Conditions

Orthodontic Indirect Bonding

Brief summary

The study evaluates the accuracy of indirect bonding using 3D printed transfer tray versus thermoformed transfer tray. Half of the brackets will be bonded indirectly using the 3D printed transfer tray and the other half will be bonded indirectly using the thermoformed transfer tray.

Interventions

Design outcomes

Primary

MeasureTime frameDescription
Linear and angular Positioning of the bracketsImmediately after bondingTo evaluate the transfer accuracy of the brackets by the two transfer trays by measuring the linear and angular differences in the brackets' positions before and after bonding.

Secondary

MeasureTime frameDescription
Bonding failure of the brackets.three monthsEvaluation of the bond failure by counting the number of detached brackets immediately and over a three months follow up period.
Chair side timeduring the bonding procedureTo evaluate the chair side time of indirect bonding in each technique
