  • 9. Mark with a pencil to show second bend point 05-Mar-12 9
  • 10. Make a second bend slightly more than a right angle 05-Mar-12 10
  • 11. Hold the wire to the model to see that the dimensions are correct 05-Mar-12 11
  • 12. Hold in the pliers just below one of the bends 05-Mar-12 12
  • 13. Proceed with a further right angled bend 05-Mar-12 13

  • 16. Tilt the wire down 05-Mar-12 16
  • 17. The wire is locked against the beak before starting to bend the arrowhead 05-Mar-12 17
  • 18. Bend the arm upwards so it follows the line of the opening of the beaks of the pliers 05-Mar-12 18
  • 19. Turn the pliers round, then the wire is pulled back on itself forming the 'U' type of loop at the bottom of the arrowhead 05-Mar-12 19
  • 20. The second arrowhead held in the pliers beak prior to bend 05-Mar-12 20
  • 21. The pliers turned to show that the first arrowhead is locked against the beak of the pliers 05-Mar-12 21

  • 34. Bend the long end of wire up so it doesn't interfere with fit 05-Mar-12 34
  • 35. The wire being adapted from over contact point into the palate allowing a space of 1mm for acrylic to flow underneath the wire 05-Mar-12 35
  • 36. Holding the leg of the clasp, bend a right angle towards the palate, This is designed to keep the leg of the clasp off the palate 05-Mar-12 36
