Which fixation method involves indirect bonding to enamel?

• A. Direct collage
• B. Indirect collage
• C. Cementation
• D. Co-optation

Answer: (B)

Indirect bonding to enamel is when brackets are first positioned on a model and a custom transfer tray is made, then seated on the teeth so the brackets are bonded in their final positions all at once. The enamel is prepared and adhesive is applied appropriately, and the tray transfers the brackets onto the teeth, where the bonding is completed. This method differs from direct bonding, where each bracket is placed and bonded individually directly onto enamel in the mouth. Indirect bonding offers greater control over bracket placement and can reduce chair time, making the process more efficient. Cementation is a broader term for luting materials used to seat appliances like bands, not the typical transfer-based bracket bonding, and co-optation isn’t a standard bonding method in this context.
