Can an adult patient have difference ANB values at the same time? ANB = 1.4 and ANB = 1.9?

[@alhuwaizi]

Yes if he has forward mandibular drift like in postural class III

[@thequiettravellers]

@@alhuwaizi Thanks for the reply. But if you are preparing a patient for surgery, is it possible to measure two different ANB values, like the values quoted above, at around the same point in time?

[@anhchinhnha5532]

when using spring torque on rectangular wire, you choose Stainless steel wire or NiTi wire?

How do you get the values for sin and con at 4:54?

[@reemesam5996]

Sin (angle) in a triangle = the opposite side divided by the hypotenuse , thus in this case sin 20 = fv/150 , therefore fv = 150 x sin 20 = 51 gm

[@reemesam5996]

Cos angle = adj/hypotenuse

Thank you so much, Professor, that was Brillant very clear and simplified :D Can you please give me 03 must-read orthodontics books about fixed appliances for GP ?

Thank you Dr Q: HOW can we make small section "round in rectangular wire" To get perfect effect of torque spring,? ..and which wire you prefer with 22 slot + torque spring ..16×16 or 16 x22 or 18×25 ؟

[@alhuwaizi]

You can grind the wire by a bur. I prefer a smaller diameter wire, preferably 16x25 or 17x25 but the spring has to be made for this wire
