Abstract
|
|
|
In order to investigate the mechanical stability in interosseous wiring according to the shape of the wire ligature, the diameter of wire, the distance between the drilled holes and the kinds of external force.
Five different shapes of the wire ligature were tested on two PVC plates (70 x 30 x 10mm) with drilled holes using each diameters of 0. 32, 0.46 and. 0.56 mm stainless steel wire for tensile and bending test.
The results were as follows;
1. The wires were cut at the twisted joint.
2. Regarding the shape of the wire ligature and the kind of external force the double ligature showed the greatest strength and the figure-of-eight ligature was the poorest form. But with regard to the bending test, the combined simple and figure-of-eight ligature was the most stable, and the type of simple ligature showed the lowest resistance to bending.
3. Increasing the diameter of the wire improved the stability.
4. The stability increased with increasing vertical distance between the drilled holes.
