In straight wire appliances, which statement best describes bracket design?

• A. They require indirect bonding
• B. Brackets are designed for specific teeth
• C. Brackets are identical on all teeth
• D. They are not prescription-based

Answer: (B)

In straight wire appliances, the brackets are built with tooth-specific prescriptions. Each bracket is shaped and angled differently for each tooth, with a defined torque, angulation, and height tailored to that tooth’s position in the arch. This design lets a single straight wire connect all brackets and, through the wire’s path, produce the intended tooth movements with minimal bending. That’s why the best description is that brackets are designed for specific teeth—they’re not the same on every tooth and they carry a preset prescription to guide alignment. Other statements don’t fit because straight wire systems don’t require indirect bonding as a defining feature, and brackets are not identical across all teeth; they’re customized to each tooth. They are indeed prescription-based, not non-prescription.
