What are the sizes of the two modern edgewise appliances?

Explanation:
In modern edgewise systems, bracket slot size determines which archwires can engage the bracket and how much control you have over tooth movement. The two standard sizes commonly used are 0.018 inch and 0.022 inch. The smaller slot is used early in treatment with lighter wires to achieve initial alignment, while the larger slot accommodates larger rectangular wires later for better torque control and finishing. This pair of sizes is the typical setup clinicians rely on today, which is why 0.018 and 0.022 inches are the correct answer.
