Which step follows the 3D scan in creating individualized brackets?

• A. Take a new impression
• B. CAD-CAM cut brackets to contour bases
• C. Direct bonding of brackets
• D. Purchasing standard brackets

Answer: (B)

In a digital workflow for individualized brackets, the scan provides a precise digital model of the patient's teeth, and the next move is to use that data to customize the brackets. CAD is used to design each bracket and, importantly, to contour the bracket bases to fit the exact surfaces of the scanned teeth. Then CAM fabricates the brackets from the chosen material, cutting or milling the bases so they seat correctly on every tooth. This sequence—designing with CAD and manufacturing with CAM based on the 3D scan—is what enables individualized brackets. Bonding and use of standard brackets would come later, and taking a new impression isn’t needed since the digital model already exists.
