Townies discuss. gekkeg Member Since: 10/21/08 Post: 1 of 6 I would like to see a discussion of this topic because I am working in an office that has an inventory of .022 braces due to the previous doctor’s preference. I was trained (Loma Linda) in Bioprogressive .018 and am used to lighter forces and archwires, higher torqued incisors and less torqued cuspids prescription versus Roth. I realize you can get used to either and vary the wire size to affect your outcome, but I worry about excessive force and discomfort using the larger wires necessary in .022 for torque as I like it. Opinion based on experience is appreciated. n Gary APR 29 2013 firm Member Since: 08/08/05 Post: 2 of 6 vraj Member Since: 02/25/09 Post: 3 of 6 t Looking for more? Find it on the Orthotown.com message boards. What Prescription/Slot Size Are You Using and Why? Search: Slot Extraction and Slot Size Search: Slot Size I have used both but prefer .018 slots. The .022 slot is more forgiving but I have fewer inventories with the .018 slot. My molar tubes are still .022. n APR 29 2013 .022 Pros: • Better leveling without resorting to curves • More convenient for sliding mechanics • Less wire deformation (19x25SS) during space closure Cons: I have not really had any issues with it .018 Pros: • Earlier (better?) torque expression • Less inventory of wire sizes • Potentially less discomfort due to relatively smaller wire size Cons: • Leveling can be challenging • Wires may deform easier • Sliding mechanics are more difficult (16x22 may get distorted, 17x25 may bind too much) n APR 29 2013 charlestonbraces Member Since: 06/05/09 Post: 4 of 6 I’m sure it has been measured before, but regarding forces, wouldn’t a 17/25SS in an 18 produce a similar force to an 18/25 or 19/25SS in a 22? I am assuming that the 17 in an 18 slot will have the smaller slop/angle than the 19 in a 22 slot, and thus have a similar force given the smaller thickness wire. n APR 29 2013 vraj Member Since: 02/25/09 Post: 5 of 6 It might be a function of how the wire is loaded i.e., bending vs. torsion. In torsion (third order), the wire-bracket slop/play, wire material, method of ligation, edge bevel, etc., would continued on page 20 18 JULY / AUGUST 2013 // orthotown.com http://www.orthotown.com http://www.Orthotown.com http://www.orthotown.com/MessageBoard/thread.aspx?a=11&s=6&f=710&t=194318&g=1 http://www.orthotown.com/MessageBoard/thread.aspx?a=11&s=6&f=693&t=186998&g=1 http://www.orthotown.com
