After space closure what is the best way to keep arch consolidated ?

· Place omega loop anterior to terminal tubes.
· Tie back with ligature tying plier.


Advantage of tying back with omega loop:
· Active force holds contact points together.
· Small spaces can be closed by tightly tying back.
· Unnecessary to change power chain every month. open.
· Space do not inadvertently open.


How Do You Tie Back
1. Use steiner ligature plier.
2. Use .014 S.S. ligature wire.


Is it necessary to tie back every arch?
Ans: NO.

When placing curve of spee in the maxillary arch
(Round or rectangular wire)
TIE BACK OR FLARE ANTERIORS

When placing reverse curve of spee in mandibular arch using rectangular wire, -5 degrees torque prevents flaring.
When placing reverse curve of spee in mandibular arch using round wire
Tie back or fare anteriors
