Which fixation method involves a direct bonding process to enamel?

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

Answer: (A)

Direct bonding to enamel involves attaching the bracket directly to the tooth surface after enamel is prepared with acid etching and a resin adhesive, which is cured in place. This chairside method creates a micromechanical bond directly to the enamel. Indirect bonding places brackets on a model first and then transfers them to the teeth, so there isn’t a direct bond formed on the enamel during placement. Cementation uses cement to attach bands or other appliances to teeth rather than bonding brackets directly to enamel, and the term presented isn’t a standard bonding method. So, the process that involves a direct bond to enamel is the direct bonding of the bracket to the enamel surface.
