0.022 inch of groove, wherein 0.022 inch groove system is even more absolute leading position.But the groove specification of both main flows
Suffer from respective shortcoming.The main arch wire rescued of routine smooth slip in bracket groove is to need clearance between the two not
Less than 0.002 inch, in 0.022 inch of groove system, the main arch wire rigidity of 0.020 inch of rustless steel is too strong, selection of can only compromising
0.019*0.025 inch stainless steel silk, but in fact 0.019*0.025 inch stainless steel silk rigidity is also bigger than normal, does not meet filament
Low force rescue theory.But if selecting 0.018*0.025 inch, 0.017*0.025 Rectangular SS archwires, more than main arch wire and bracket
Gap is excessive to cause torque give full expression to, though can make up by following several means, there is also shortcoming, such as can be
Preset excessive torque on bracket, but the versatility of bracket can be brought not good to some cases for not needing retract anterior teeth.Also
It is to correct torque by bending bent or auxiliary bow, but complex operation after all.Near complete with a 0.021*0.025 at the end of also
Size titanium-nickel wire is expressed, one be exactly arch wire size run counter to greatly very much filament low force rescue theory, another is just the increase in
Consumables cost.And the bracket system of 0.018 inch of groove meets the standard of filament low force, if but which closes gap with sliding scale,
On the premise of 0.002 inch of clearance is ensured, main arch wire low strength.If selecting to close gap Qu Guan gap, although can be perfect

Sufficiently expensive also govern of valency is promoted to popular.
The data of country's bracket are substantially to design according to westerner at present, during these bracket data are not entirely suitable to
Compatriots' tooth contour feature, the arrangement snap feature of Chinese's normal occlusion, and not fully meet Chinese aesthetical standard.
The labial teeth torque ratio Chinese of occidentals are little, and labial teeth shaft rake compares National People's Congress.The central incisor of occidentals and lateral incision are first
Sequence direction stereovision is obvious, and this is conducive to aesthetics on the basis of occidentals's property faced directly, face type profile are obvious, but to Chinese
More seem on the basis of prominent face type is more that front tooth is projected and be unfavorable for aesthetics.In terms of occlusion the canine tooth of occidentals and grind one's teeth in sleep first outside
Exhibition is all less compared with Chinese.This causes to correct using the existing bracket based on occidentals's dental features before terminating, and also wants volume
Excurvation yeast production carries out various regulations, not only wastes time and energy but also effect is bad.
