Which of the following is a disadvantage of direct bonding?

• A. Longer chair time
• B. Less accurate placement
• C. Higher bond strength
• D. No lab time needed

Answer: (B)

Direct bonding’s big drawback is less accurate bracket placement. When brackets are bonded directly at the chairside, placement relies on the clinician’s line of sight, angle, and feel, which can introduce small but meaningful errors in mesio-distal position, height, and angulation. These placement issues can compromise the intended tooth movement, torque control, and treatment efficiency, sometimes requiring repositioning or refinements later. Indirect bonding, by contrast, positions brackets on a model and uses a transfer tray, which tends to produce more consistent, precise bracket placement across the arch. So, the primary disadvantage of direct bonding is the potential for less accurate placement, even though it avoids lab steps and may involve longer chair time in some cases.
