Which of the following is an advantage of indirect bonding?

• A. Precise positioning of the brackets
• B. Less chair time needed for bonding
• C. Requires no lab work
• D. Increased bracket failure rate

Answer: (A)

Indirect bonding focuses on placing brackets in ideal positions on a model and transferring them to the teeth with a custom tray, so the final in-mouth positions are highly controlled and reproducible. By planning and validating each bracket’s mesiodistal position, height, and angulation on a dry model, you eliminate much of the guesswork and moisture-related errors that happen with direct bonding. When the transfer tray is used, all brackets go to their designated orientations at once, improving overall accuracy and alignment of the teeth from the start. This precision translates into more predictable treatment outcomes and fewer adjustments later.

While indirect bonding can reduce chair time in some setups, the key advantage is the accurate, consistent bracket placement. It does involve lab work to prepare the transfer tray, and a higher bracket failure rate would be a drawback, not an advantage.
