这是dr. M alan bagden在3rd Asian Damon Forum(2009.3.24)里所提出的,摘录于下

1) vary torques in initial prescription to achieve clinical final results

 

              damon system: variable torque  (central incisor)

    有Low torque(矫正器上以绿点标示)   + 7度 (Lingual crown torque=labial root torque)

    有standard  (+12度)

    和high(Super) torque(矫正器上以红点标示)   +17度(Buccal crown torque=lingual root torque)

以上三种矫正器若是都以反过来黏(upside down=inverted),则各为-7,-12,-17度的more lingual crown torque

2)always bond 2nd molar to fascitate alignment,bite opening, and root control

3)take a pano,after rectangular Cu NiTi phase and reposition any improper bracket placements   (some dr. don't think so)

4)follow the newest ideal archwire progressioning

5)develop the lateral dimension through  archwire and balancing to orthodontic forces with facial musculature rather than inserting high forced RPE

6)deep bite can be opened using different options based on lower arches requirements

7)place chain for consolidation under the archwire to minimize binding and friction

8)move  teeth in group rather than individually. maintain constant blood supply to all teeth

9)close spaces on pre-posted SSW in the final phase. finishing cases(arch form and detailing) in rectangular TMA or SSW.

finish in SSW/TMA    ●19x25,16x25 SSW

                                              ●19X25, 17x25 TMA

NiTi coil spring (Medium)  ●4~~6oz , 9mm

                                                          ●Activation to 18 mm

archwire Not extend to 2nd molar ●  Friction↓ / irritation↓

anchorage control  ●Figure 8 tie-together

                                         ● OBS(ortho bone screw)

10)CL II ,III elastics extend from the posts of final archwire to 1st molars.use 5/16" 6 oz elastics at night in difficult adult case

Quail~~Fox~~Bear~~Moose (ormco elastics的型号包装) ~~be progressive!

11)modify the final archwire for each individual p't based on the arch form developed by the balance of forces. this form is established by the end  of Hi-tech wire phase and based on the lower arch form.

wax bite(Lower) after 16 x 25 Cu NiTi

Lower arch form/ width  EQUAL            3-3 the same !!

Upper > Lower  1~2 mm 

EXT. case : add more 2 mm for prevent narrowing during space closure

12)be patient!! things can go slow and then happen all of a sudden
