I use 0.022 slot and almost never use bigger than 16 22, 17 25 in some rare case. To the best of my knowledge most of the orthodontist in South Easia work the same. Pros and Cons of .022 Versus .018 Slot Braces for the same deflection (for example a 1mm step in 17x25 SS vs. 19x25 SS). This is clini-cally manifested by the ease of leveling using 19x25 SS in a .022 slot when compared to 17x25 SS in the .018 slot. The only advantage I see in .022 is more archwire selection in extremely complicated cases. Otherwise, I love an .018 slot. 18 - versus & 22 - slot - SlideShare
