Comparison Between Digital 3D Printed Transfer Tray Versus Thermoformed Transfer Tray for Indirect Bonding

Not Applicable

• Conditions: Orthodontic Indirect Bonding
• Interventions: Procedure: Digital indirect bonding; Procedure: Conventional indirect bonding; Procedure: Intraoral scanning; Procedure: Superimposition and evaluation

• Registration Number: NCT03363607
• Lead Sponsor: Cairo University

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.

Primary Outcome Measures

Name	Time	Method
Linear and angular Positioning of the brackets	Immediately after bonding	To 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 Outcome Measures

Name	Time	Method
Chair side time	during the bonding procedure	To evaluate the chair side time of indirect bonding in each technique
Bonding failure of the brackets.	three months	Evaluation of the bond failure by counting the number of detached brackets immediately and over a three months follow up period.
