Introduction
 Orthodontics is the study of the diagnosis, prevention and treatment
of irregularities of the teeth and jaws.
 Orthodontic instruments are used in conjunction with fixed and
removable appliances.
 For orthodontist, it is essential to know that the instruments that
have to use routinely. It is expected to increase the working
knowledge of the orthodontist and also prevent the misuse of more
delicate instruments.

Stainless steel and tungsten carbide are the two materials
routinely used for cutting edges of the instruments.
The advantages of tungsten carbide tips over stainless steel are
1. More durability.
2. Precise cutting performance.
3. Sharp cutting edge.
4.Three times more stiffer than stainless steel.
5. Resistant to scratches.
6.The cutting edge maintains sharpness and alignment.
7. Extra grip.
Disadvantage is brittle of the material (Tungsten carbide)

 Stainless steel : Extremely corrosion resistant.
 Cutting inserts and tips : Made of hard metal.
 Tungsten Carbide Tips : Stiffer and denser than steel.
 Shape and screw joint : Ergonomically designed to meet any orthodontic
requirement.
 Gold brazing : For longer instrument life.
 Rounded tips : For patient comfort and safety.
 Serrations on working ends : To improve grip.
 Bow out handles : Comfortable Handling.
Features of Orthodontic instruments

Classification of Orthodontic instruments
classification of orthodontic instruments was based on the sequential
procedures carried out during orthodontic treatment, right from
separation of teeth for banding till debonding and debanding
procedures up to completion of orthodontic treatment.

 Separating plier or the separator placing plier is made up of
stainless steel with spring back action.
 It is used for expanding elastic separators or separating rings
before positioning them interdentally.
 Barrel-shaped tip prevents slippage of the module, reduces the
risk of tissue damage.
 Angled beaks facilitate easier placement of elastic separators in
anterior and posterior areas.
SEPARATING PLIERS or SEPARATOR PLACING PLIER

It is available in either straight or curved pattern and long
and short cutting edge pattern.
• It is made from especially hardened stainless steel with
tungsten carbide inert cutting tip.
• It is used for cutting thin metal bands or band material.
Band cutting Scissors
Band forming instruments

 Handle is cylindrical and working end is serrated.
 It is used to push bands so as to seat them and / or adapt
them to the exact contour of the teeth.
 A hollow anatomically formed grip handle makes the band
pusher light and the serrated rectangular tip provides for a
good transfer of force when positioning bands.
Mershon band pusher

 Band seater is available in various shapes and are generally
made of high impact plastics or wood .
 The biting surface is generally tin inlay. Its shape is round,
square or triangular (allows easy access to interproximal
area) with a serrated surface finish .
 Square tip allows maximum grip and prevent slippage.
 It is used for patient to bite on the surface with the tin inlay
tip resting on the lug or the band edge.
Nylon band seater

 It is used to contour the gingival surface of preformed bands
to provide better tooth anatomy.
Band crimping plier

 The Johnson band contouring plier is ideal for contouring and
adapting bands.
 Beaks are tapered with a slight bow. One beak is concave while the
other is convex allowing re-contouring of bands.
 It can be used to re-contour band edges that sometimes get bent
during band placement.
Johnson band contouring plier

Band pinchable plier
 Beaks are in triangular passion with inner surfaces had serrated for
better control of band material.
 It is used for pinching of bands during band preparation.
 It has two types curved and straight.
 Curved (45˚) pinchable plier used for lower band preparation , and
straight is used for upper band preparation.

 It is used for preparation of band to tooth.
• Contour fitting to the side of a tooth is aided by the concave
surface or depression at the outer ends of each of the band
clamping portion.
 The purpose of the elevated edge is to provide a friction contact
with a portion of the material of the strip to prevent it from slipping
in the use of the plier in the operation of forming a band around a
tooth.

 It is made of stainless steel, the double beak pliers are used for
forming bands in the mouth.
 These are available separately for anterior and posterior band
fabrications.
 These were of immense importance when all teeth used to be
banded.
Double beak pliers

Anterior band remover plier
It have a narrow groove into which the incisal edge of the
anterior tooth is placed and the sharp end is inserted gingival to
the gingival extension of the anterior band.
Band removing pliers

Oliver Jones Posterior band removing plier
It is used to remove posterior metal bands with
maximum patient comfort.
The tip is postured in middle of the pad for easy
removal of bands.
A plastic padded tip and sharp removing beak
with a slight pressure allow easy band removal.
Plastic head rest on the occlusal surface of tooth
and the sharp tip below the gingival contour of
the band.The pressure at handles causes the band
to lift off the tooth.

seating the bracket on the teeth with exactly the right distance
between bracket slot and incisal edge with pencil lid or metal
tips.
Boons Gauge
Bracket positioning instruments

for bonding.
Bracket holder

 It is used to organise and hold orthodontic brackets to facilitate
quick bracket placement.
 Each circle on the card corresponds to a particular tooth in the
mouth.
 Brackets are placed corresponding to the tooth to be bonded.
 Tape on the back of the card helps to keep brackets in place.
Orthodontic bracket card

• Bracket removing pliers are used for removing bonded brackets.
• The wide tips wedge between both the edges of the base of the
bracket and the tooth surface(incisal-gingival direction), easily
lifting off the bracket.
• Available in two forms as straight (for anterior debonding) and
with a 60° angled tip (which allows better access to posterior
areas).
• Anterior debonding plier is also used for removal of adhesive
remanant on enamel surface after bracket debonding.

Tube converting plier

It is used for the conversion of convertible molar tube into bracket.
Procedure :
Step 1: Insert instrument into mouth with the slide mechanism parallel
to the arch plane and the handles pointing outward.
Step 2 :With handles wide open (slide bar tip fully retraced) align and
insert tip into arch wire slot of buccal tube. Close handles slowly until
anchor tip of pliers is firmly supported on distal end of the buccal tube.

Step 3 : Maintaining instrument alignment, close handles slowly and steadily,
driving the slide bar tip into the arch wire slot.The convertible cap will
peel away, converting the buccal tube to a molar bracket.
Step 4 : If the slide bar tip is adjusted for partial conversion, open the plier
handles fully and carefully remove the instrument from the patient’s mouth. If
the tip is bound up in the arch wire slot, slowly pivot the entire instrument
outward to free the tip.The partially converted cap can be securely grasped
with a utility pliers, rotated distally to break away the attachment and removed
from the patient’s mouth.

ReplacingThe Slide BarTip : Open pliers handles to retract slide
tip half way and hold this position. Remove the slide bar retaining
screw.
Grasp the tip with a utility pliers, rotate upward and remove the tip.
Insert a fresh tip, replace and tighten retaining screw securely.

Conclusion
Various orthodontic instruments and pliers that are specially designed
for Orthodontic purposes are used in orthodontic practice.A basic
thorough knowledge is required for proper use of instruments for
their purpose without damaging instruments and orthodontic
materials.
