Indirect bonding uses a transfer tray to hold brackets in their exact planned positions on a model and then seats on the teeth to place all brackets at once. This method is chosen when a system relies on precise bracket placement to deliver its specific archwire prescription and torque control.

In the described system, the protocol is built around that tray-based transfer, so brackets must be placed indirectly to realize the planned positions and orientation. The tray stabilizes bracket locations, minimizes errors from moisture or patient movement, and aligns with the system’s prescribed geometry, making indirect bonding a required step rather than optional or unnecessary. While indirect bonding can reduce chair time in some cases, claiming it is always faster isn’t accurate; here, its use is mandated by the system’s workflow.
