How to Add a Wire of TopoDS_Shape

Hello Sir,
I have create a wire (mysgWire) of 6 edges and transformed/Rotated that wire(mysgWire) about origin. When I have rotated that wire it comes in TopoDS_Shape, my problem is that how to add a wire having TopoDS_Shape class.
My Code in short as:
{
BRepBuilderAPI_MakeWire sgWire;
sgWire.Add(Arc31);
sgWire.Add(TE8);
sgWire.Add(Arc11);
sgWire.Add(Arc21);
sgWire.Add(Arc41);
sgWire.Add(TE9);
sgWire.Add(Arc51);
TopoDS_Wire mysgWire = sgWire.Wire();

gp_Pnt P1(0,0,0);
gp_Dir xDir(0,0,1);
gp_Ax1 xAxis(P1, xDir);
double gtangle2 = sg.m_gt*PI/180;
gp_Trsf myTrsf2;
myTrsf2.SetRotation(xAxis,gtangle2);

TopoDS_Shape teeth2 = BRepBuilderAPI_Transform (mysgWire, myTrsf2);

}

Now if want to make a complete wire of mysgWire and teeth2, What I have to do.

Waiting for urgent rpl.

Thanks in advance.
