What is the technique for fixing the aggregation elements of fixed orthodontic appliances to the enamel?

• A. Aggregation
• B. Co-optation
• C. Collage
• D. Decollage

Answer: (C)

Bonding brackets to enamel uses collage, the adhesive bonding of the brackets to the tooth surface. The enamel is conditioned first, typically by etching with phosphoric acid to create microscopically roughened areas that resin can lock into. After rinsing and drying, a bonding agent is applied, followed by the resin adhesive on the bracket base. The bracket is then placed on the tooth, excess adhesive is removed, and the resin is cured with a light source to secure the bracket. This method provides a strong, durable bond while preserving enamel and allows for debonding at the end of treatment. The other terms don’t describe attaching brackets to enamel: they refer to removal (decollage) or are not standard bonding terms.
