 GENERAL PRINCIPLES OF WIRE
BENDING
 IMPORTANCE OF BASIC WIRE BENDING
EXERCISES
 PLIERS USED FOR WIRE BENDING
 WIRE BENDING METHOD
 ADAM’S UNIVERSAL PLIERS


GENERAL PRINCIPLES OF
WIRE BENDING
 AII BENDS IN ORTHODONTIC WIRES ARE
PLACED BY THE FINGERS, PLIERS ARE
MEANT TO HOLD THE WIRE FIRMLY AND
ASSIST IN WIRE BENDING.
 ALWAYS HOLD THE PLIER USING A PALM
GRIP.
 BEFORE STARTING TO BEND THE WIRE,
ESTABLISH A FIRM GRIP OVER THE WIRE.
 IN GENERAL,SHARP BENDS SHOULD BE
AVOIDED TO PREVENT INCORPORATION OF
STRESSES WHICH CAN LEAD TO THE
FRACTURE OF THE WIRE LATER.

 IT IS EASIER TO MAKE A BEND BY
PUSHING THE WIRE, RATHER THAN
PULLING THE WIRE.
 USE PROPER BEAK OF THE PLIER TO
HOLD THE WIRE BEFORE PLACING
THE BENDS.
 PRECISE MARKING IS NECESSARY
BEFORE MAKING ANY BENDS.


 TO MAKE A RIGHT ANGLED BENT;
MARK THE POSITION WHERE
THE BENT SHOULD BE MADE, HOLD
THE WIRE FIRMLY WITH THE PLIER,
PUSH THE WIRE CLOSE TO THE PLIER
USING THE THUMB AND FOREFINGER.
 TO MAKE ACUTE BENDS;
MAKE A RIGHT ANGLED
BEND, THEN WITHDRAW THE PLIER
SLIGHTLY AWAY FROM THE MARK AND
CLOSE THE ANGLE.

 TO MAKE A SHORT CURVE BEND;
HOLD THE WIRE FIRMLY WITH
THE PLIER AND MAKE THE BEND WITH
THE FINGERS.
 TO MAKE CIRCLE OR ARC OF A
CIRCLE;
THEY ARE MADE WITH THE
FINGERS ONLY


IMPORTANCE OF BASIC WIRE
BENDING EXERCISES
1 STRAIGHTENING OF WIRE;
WIRES-SUPPLIED IN ROLLS, ALL
THE WIRE BENDING HAS TO BE
STARTED ON A STRAIGHT WIRE.
2 MAKING A SQUARE/ RECTANGLE;
RIGHT ANGLED BENDS.
3 MAKING A TRIANGLE;
ACUTE ANGLED BENDS


4 MAKING A CIRCLE;
SHORT CURVED BENDS, LABIAL BOW,
PALATAL BOW etc.
5 ‘ U’ LOOPS AND ‘V’ LOOPS;
MARK AND MAKE PRECISE BENDS AT
SHORT INTERVALS
6 MAKING COILS;
COILS OF SPRINGS, LABIAL BOW
MODIFICATION etc.

CHECK LIST FOR THE
SELECTION OF PLIERS
 STAINLESS STEEL PLIERS ARE PREFERRED OVER
THE STAINLESS STEEL PLATED PLIERS.
 CARBIDE TIPS/ TUNGSTEN CARBIDE TIPS ARE
PREFERRED FOR CUTTING INSTRUMENTS.
 THE BEAKS OF PLIER OR THAT OF A CUTTER
SHOULD BE CLOSE TO ONE ANOTHER
WITHOUT ANY SPACE IN BETWEEN WHEN
THEY ARE CLOSED.


WIRE BENDING METHOD
WIRE MAY BE FORMED IN TWO WAYS;
1.SPECIAL PLIERS
2.VERY SIMPLE BUT STRONG AND
ACCURATE PLIER.


ADAM’S UNIVERSAL PLIERS
ESSENTIAL FEATURES;
 MADE OF A STEEL THAT IS HARDER THAN THE
WIRES THAT THEY WILL BE USED YO FORM.
 THE DISTANCE BETWEEN THE HINGE PIN AND THE
TIPS OF THE BEAKS IS SHORT.-22mm IS THE OPTIMUM
LENGTH.
 THE HANDLES ARE WIDE AND COMFORTABLE TO
HOLD.
 THE SIDES OF THE BEAK MUST BE FLAT.
 THE SHAPES OF THE BEAK MUST BE AS SHOWN IN
FIGURE.


 THE EDGES OF THE GRASPING SURFACES OF
THE BEAKS MUST BE SHARP AND NOT
BEVELLED OR ROUNDED.
 THE GRASPING SURFACES OF THE BEAKS
SHOULD BE MAT FINISHED.
 WHEN THE BEAKS ARE CLOSED, THE TIPS
SHOULD BE IN CONTACT BUT THERE
SHOULD BE A SLIGHT GAP AT THE HINGE
END OF THE BEAKS TAPERING DOWN
EVENLY TO CONTACT AT THE TIPS.


THIS GAP AT THE HINGE SHOULD BE 0.6mm [AT THE
WIDEST PART] SO THAT WHEN THE TIPS OF THE
BEAKS ARE OPEN TO 1.0mm THE INNER SURFACES
OF THE BEAKS ARE PARALLEL. IT IS THUS POSSIBLE
TO GRASP A 1.0mm WIRE.
 THE SIDES OF THE BEAKS SHOULD BE PERFECTLY
FLAT.
 THE HINGE OF THE PLIERS SHOULD BE STRONG
WITHOUT BEING TOO BULKY & THE HANDLES
LARGE & COMFORTABLE WITHOUT MAKING THE
PLIERS HEAVY & CLUMSY TO HANDLE.
 AN OVERALL LENGTH OF 5 ¼ INCH IS ABOUT RIGHT.

FORMING WIRE WITH
ADAM’S UNIVERSAL PLIER
 WIRE IS BEND WITH THIS PLIER BY HOLDING
IT IN ONE HAND AND APPLYING PRESSURE
WITH THE THUMB OF THE OTHER HAND,
WRAPPING THE FINGERS ROUND THE FREE
END OF THE WIRE TO AID COMPLETE
CONTROL OF THE BEND.
 WIRE IS NEVER BEND AROUND THE ENDS OF
ADAM’S UNIVERSAL PLIERS. WIRE IS BEND
UPON ITSELF, USING THE PROPERTIES OF
THE WIRE TO OBTAIN THE REQUIRED FORM.

 SMOOTH CURVES
BY HOLDING THE END OF THE ARCH
WIRE IN THE PLIERS AND WIPING A BEND IN
TO THE WIRE USING THE THUMB OF THE
OTHER HAND .
 SMOOTH BENDS
BY MAKING A SERIES OF SMALL BENDS ,
ADDING THEM IN TO A GENTLE BEND UP TO
A FULL CIRCLE.


 RIGHT ANGLE BENDS
BY LAYING THE WIRE ACROSS THE
BEAKS OF THE PLIERS , HOLDING AND
BENDING THROUGH A RIGHT ANGLE .
LIGHT WIRES – BEND NEAR THE TIPS OF
THE BEAKS
HEAVIER WIRES – NEAR THE HINGE.


 ACUTE BENDS

HEAVY WIRES:-ARE FAST BEND TO A RIGHT
ANGLE , THE WIRE IS THEN LAID OBLIQUELY
ALONG THE LENGTH OF THE BEAKS IS USED
TO HOLD THE WIRE WHICH IS THEN BENT
OVER THE TIPS OF THE BEAK IN TO AN
ANGLE OF THE REQUIRED ACUTENESS.


 CLOSURE OF ANGLES
THE ANGLE IS CLOSED SO THAT THE LIMBS LIE
PARALLEL, - THE BEND IS COMPRESSED BETWEEN
THE BEAKS OF THE PLIERS.
 CORRECTION OF AN INCORRECT BEND
THE INCORRECT PORTION OF THE BEND IS
GRIPPED IN THE TIPS OF THE PLIERS & SQUEEZED.
THIS STRAIGHTENS THE SMALL SECTION OF THE
WIRE WITHOUT INTERFERING WITH THE
REMAINDER OF THE BEND. THE WIRE IS THEN BENT
AT THE CORRECT POINT.


 HOOK
BY MAKING A RIGHT ANGLE & AN ACUTE
ANGLE BEND. – NO SPECIALIZED PLIERS ARE
REQUIRED.
 ACUTE BENDS IN FINE WIRES
BY FIRST MAKING A RIGHT ANGLED
BEND . THE3 WIRE IS THEN HOLD IN THE
TIPS OF THE BEAKS OF THE PLIERS AND THE
WIRE IS BENT THROUGH A SECOND RIGHT
ANGLE.
