Introduction:
I Learned this trick from others on Dental Town. Passing it on.
Matrix within a matrix
Step 1
Struggled to get Greater Curve band to go beyond the distal margin. Placed a rounded cut band fragment within the matrix past the margin. Look closely and you can see the piece of stainless within the confines of the GC matrix.

Band Fragment
Step 2
The band fragment was cut from the middle portion of the GC band.

Restoration
Step 3
Tooth restored with Activa. The band fragment also kept the Activa from extending too far distally. This made shaping the distal simpler. There was less bulk to cut back.
