Cast stainless steel brackets are characterized by which of the following?

Cast stainless steel brackets are characterized by which of the following?

• A. Less accurate
• B. Cheaper but weaker
• C. More accurate
• D. Not durable

Answer: (C)

The key point is the precision achieved by the casting method. Investment casting creates bracket components with very tight, uniform tolerances for the slot and base geometry, so the bracket seats consistently on the tooth and the wire engages the slot with minimal variation. That predictability translates into better control of tooth movement, especially torque, because the forces are applied through a reliably accurate interface. Stainless steel itself remains durable and corrosion-resistant, so casting isn’t about being weaker or less durable; it’s about achieving higher dimensional accuracy.
