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

Study Overview
=================
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Linear and angular Positioning of the brackets | 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. | Immediately after bonding | 

Secondary Outcome Measures

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