In block bypass

This is another way to extrude teeth and to close bites. It is very similar to the individual bypass; the difference

is that this technique is done to a group of teeth. We can use sectional round or rectangular wires in the zone to be extruded (placed in the slot of the braces) and the bypass of NiTi or TMA with a diameter of 0.016" to 0.020" is placed above the braces.
