Dentin is the hard connective tissue that forms the bulk of the tooth. It consists of tubules throughout its thickness and determines the shape of the tooth crown. Dentin is formed by odontoblasts that differentiate from dental papilla cells and produce an organic matrix that becomes mineralized. There are three types of dentin - primary, secondary, and tertiary. Primary dentin forms most of the tooth, secondary dentin is deposited after root formation, and tertiary dentin is reparative dentin deposited in response to stimuli. Dentin has a tubular structure and contains both collagen and hydroxyapatite crystals.

Friction is a force between two surfaces in contact that opposes their sliding or moving past each other. The amount of friction depends on the materials the surfaces are made of, with rougher surfaces producing more friction. Friction produces heat and can be useful to prevent slipping, but sometimes needs to be reduced, like with lubrication between engine parts or streamlining vehicles to reduce air resistance.

1. Orthodontic wires- SS, Co-Cr, Australian shrestha.pptxanweshagarg49
This document discusses orthodontic archwires, including their basic properties and types of stainless steel wires. It begins with definitions of archwires and wire dimensions. It then discusses the evolution of orthodontic wires from early noble metals to modern materials like stainless steel, nickel-titanium, and beta-titanium alloys. The document focuses on the basic properties of orthodontic wires, including strength, stiffness, resilience, formability, and others. It explains these properties with diagrams and definitions. Finally, it discusses how wire size and shape can affect elastic properties.
RECENT ADVANCES IN ORTHODONTIC ARCH WIRE.pptxPratik677380
This document discusses various types of arch wires used in orthodontic treatment. It begins by describing ideal properties of arch wires such as stiffness, strength, spring back, formability, and biocompatibility. Titanium niobium wire and timolium titanium wire are introduced as advances in arch wire materials. The document then discusses several other arch wire types including super cable, combined arch wires, multistranded wires, bioforce wires, optiflex wires, and teflon coated stainless steel wires. For each type of arch wire, its composition, properties, advantages, and clinical applications are described.
Dr. Zeba Siddiqui presented on various orthodontic archwire materials. Several archwire types were discussed including Optiflex, Bioforce, Super Cable, graded and formable nickel titanium wires. Optiflex is a clear aesthetic wire made of optical fibers. Bioforce applies varying force levels along the arch. Super Cable is a superelastic wire made of 7 strands. Graded and formable nickel titanium wires can be customized with different force levels and bends. Other wire types discussed include titanium niobium, timolium titanium, and coated or combined wires designed for aesthetics, force delivery or finishing.
The art of orthodontics involves correction of the position of teeth and the relation of craniofacial structures.
The Teeth are moved by the use of forces and moments, which are delivered through the use of various types of wires.
From the beginning of the profession, different types of wires have been introduced to provide forces to move teeth.
Light and Continuous Forces have always been sought, and operators have tried to achieve this in a variety of ways.
This document discusses different methods of ligation in orthodontics. It describes conventional elastic or metallic ligation as well as newer self-ligating methods built into brackets. The three most common ligation systems are discussed as active/passive self-ligation and conventional elastic ligation. Research has shown passive self-ligation decreases forces and moments compared to elastic ligation. Tiebacks and lacebacks are described as methods to retract canines into extraction spaces, with tiebacks using elastics and lacebacks using direct wires from molars to canines.
Self-ligating brackets incorporate a locking mechanism such as a ring, spring, or door that holds the archwire in the bracket slot. The document discusses and compares active and passive self-ligating brackets. It notes that while active brackets may provide more complete initial tooth alignment with smaller archwires due to their clip design, they also generate more friction. Passive self-ligating brackets produce lower forces and friction, which may facilitate tooth movement. However, evidence suggests torque control is similar between active and passive designs. Overall, the evidence is mixed as to whether self-ligating brackets provide faster treatment times or better outcomes compared to conventional brackets.
This document provides an overview of orthodontic wires. It discusses the evolution of orthodontic wires through five phases, with newer phases introducing variations in force delivery methods and non-linear force-deflection characteristics.

The document discusses the Combination Anchorage Technique (CAT), which combines the Begg technique and straight wire technique. It has undergone improvements in recent years through more effective bracket and wire designs. CAT involves four treatment phases using different wires and slots to achieve alignment, leveling, torqueing, and finishing. The gingival slot allows for maximum tooth movement while the edge-wise slot provides rigidity. CAT can be adapted for various treatment plans by increasing resistance in one arch or using both gingival slots.

4. INTRODUCTION
The materials used by orthodontists have changed
rapidly in recent years and will continue to do so in
the future.
As esthetic composite archwires are introduced,
metallic archwires will likely be replaced.
Because an ideal material has not yet been found,
archwires should be selected within the context of
their intended use during treatment.
www.indiandentalacademy.com
5. Ideally, archwire are designed to move teeth with
light, continuous forces. Such forces may reduce the
potential for patient discomfort, tissue hyalinization
and undermining resorption
When force is applied, the archwire should behave
elastically over a period of weeks to months.
several properties and characteristics should be
considered in the search for the ideal archwire.
www.indiandentalacademy.com
6. Among them are esthetics, biohostability,
friction, formability, weldability, resilience, and
springback.
Currently, orthodontists principally use wires of
four major base metal alloys types: Stainless steel
Cobalt-chromium-nickel, Nickel-titanium and
Beta-titanium www.indiandentalacademy.com
7. HISTORICAL PRESPECTIVE
Gold alloys were first used in orthodontic practice,
although these noble metal wires have minimal
use currently because of their greater cost.
Their compositions were similar to base metal
wires precisely to IV gold casting alloy
Gold alloy wires had elastic force
was much less than that of S.S.
www.indiandentalacademy.com
8. With the advent of Stainless steels in World War I
and the refinement of drawing processes to form wires
in the late 1930s, gold archwires gradually lost favor to
the smaller cross-sectional areas that stainless steel
archwires can produce.
By 1950s stainless steel alloy was used by most of
the orthodontist
It has low cost, excellent
formability and good
mechanical property.
www.indiandentalacademy.com
9. PHYSICAL AND MECHANICAL
PROPERTIES
STRESS: It is a internal distribution of the load
measured as force per unit area.
STRAIN: It is the internal distortion produced by the
load ,force defined as deflection per unit area.
PROPORTIONAL LIMIT OR ELASTIC LIMIT :The
point at which first elastic deformation occurs
LDR OR STIFFNESS: For a given force deflection
within the elastic limit is known as LDR
www.indiandentalacademy.com
10. SPRING BACK: spring back is a measure of how far
a wire can deflect without permanent deformation.
STIFFNESS: It is a measure of amount of force
Required to produce a specific deformation.
STRENGTH: STIFFNESS X RANGE
RESILIENCE: Represents energy stored capacity of
wire which is a combination of strength and
springness
www.indiandentalacademy.com
11. FORMABILITY: The ability to bend a wire into desired
configuration into loop, coil and stops without
fracturing the wire.
FLEXIBILITY: The amount which a wire can be
strained under going plastic deformation
ZERO STRESS RELAXATION: This the ability of
the wire to deliver constant high elastic force when
subjected to external force or force of occlusion.
www.indiandentalacademy.com
12. SRESS RELAXATION: When a specimen has been
deformed and held in a fixed position the stress may
diminish, with time this is called as stress relaxation
COLD-WORKING: The process of plastically
deforming a metal at a temperature below that at which
it recrystallizes new grains, which is usually one-third
To one-half times its absolute melting point temperature
HEAT TREATMENT: General process of using
Thermal energy to change the characteristics of
metallicalloys as in tempering, precipitation hardening
, or annealing (a high-temperature, softening process).
www.indiandentalacademy.com
13. PHASE TRANSFORMATION: A change in the number
and/or character of the phases that constitute the
microstructure of an alloy by a change in crystalline
structure.
RANGE - The distance that an archwire can be
activated by a specific force, this distance is termed the
“working” range.
-With regard to elastic property ratios the distance
that an archwire can be activated elastically
i.e., its elastic range.
www.indiandentalacademy.com
14. EFFCT OF SIZE AND SHAPE ON
ELASTIC PROPERTIES
Major elastic properties namely-Strength, stiffness
and range is substantially effected by a change in
the geometry of beam.
Cross-section (circular, rectangular or square)
and length of the beam are of great significance in
determining its properties
www.indiandentalacademy.com
15. EFFECT OF DIAMETER OR CROSS-SECTION
Add fig 10-12 pg 335 proffit
www.indiandentalacademy.com
16. EFFECT OF LENGTH AND ATTACHMENT
If length of cantilever beam is doubled, its bending
strength becomes ½ , and springiness increases
by 8 times
Length effect on torsion quite differently
-springiness and range as length increases
-Torsional strength is not effected by length
Supported beam on both end has more strength
but less springiness
www.indiandentalacademy.com
20. This alloy consists of 18%chromium ,8%nickel
alloyed with austenitic type of stainless steel.
Cr and ni maintains the austenite at room
temp.And prevents the conversion fcc structure of
austenite to martenisitic cubic lattice structure.
By nature austenite is malleable and ductile
and martenisite is hard and brittle
www.indiandentalacademy.com
21. BRAIDED AND TWISTED WIRES
Very small diameter s.s wire can be braided or
twisted together by the manufacturer to form wires
for clinical orthodontics.
Separate strands may be as small as 0.005 or
0.010, comprised of five or seven wrapped around a
central wire of same diameter.
It affords extreme flexibility and delivers extremely
light forces, full engagement of the arch wire at an
early stage.
www.indiandentalacademy.com
22. Used at the beginning of the treatment to align
labiolingually displaced or rotated anterior teeth.
These wires are available with bright smooth finish
to give minimal friction.
They resist permanent deformation and not unravel
when cut.
They are cost efficient wires in comparison to
titanium wires.
www.indiandentalacademy.com
23. They are available in both round and rectangular
shape.
Different type of multi-stranded wires are available
1. Triple stranded – 3 wires twisted
2. Coaxial – 5 wires wrapped around a core wire
3. Braded – 8 strand rectangular wire.
www.indiandentalacademy.com
24. Stainless steel arch-wire with
soldered brass wire
Used for sliding mechanics
ADVANTAGES
Minimal chair side time.
More efficient sliding of
arch wire through posterior
slot
No running out of space
for activation
www.indiandentalacademy.com
25. DISADVANTAGES
Confusion concerning ideal force level.
Tendency to over activate elastic forces.
Insufficient force.
Damaged or crushed bracket inhibits sliding.
Cortical bone resistance due to thinning of
bone at extraction site.
www.indiandentalacademy.com
26. AUSTRALIAN ORTHODONTIC ARCH WIRE
Claude Arthur j wilcock produced this wire for
Dr.P.R.Begg
The unique charecteristics of this wire are it is
high Tensile austenitic stainless steel.
The wire is resistant to permanent deformation ,
maintaining its activation for max. control of
anchorage.
www.indiandentalacademy.com
27. All these properties make this wire very hard
and brittle.
MANUFACTURING PROCEDURE
pulse straightening the wire is pulsed in a special
machine which permits high tensile wires to be
straightened and drawn in as smaller diametres as
possible.
The material yeild strength is not altered and the
surface has smoother finish so less friction.
www.indiandentalacademy.com
28. PROPERTIES OF WIRE
1. The tensile strength of the P.S wire is 8-12% higher
than of S.S so greater resistance to fracture.
2. The LDR was high by 10%for 0.016 ps wire and by
235% to 0.020premium wires indicates that when
used for intrusion they deliver significant higher
loads
3. High working range and good recovery patterns.
4. Frictional resistence of ps wires were lesser by
50%than s.s wires.
www.indiandentalacademy.com
29. GRADING AND COLOUR CODING
- OLDER WIRES
1. REGULAR GRADE- WHITE LABEL
2. REGULAR PLUS- GREEN LABEL
3. SPECIAL GRADE- BLACK LABEL
4. SPECIAL PLUS- ORANGE LABEL
5. EXTRA SPECIAL PLUS- BLUE LABEL
www.indiandentalacademy.com
30. NEWER WILCOCK WIRES
Newer grade of wires came to market with superior
properties with advent in manufacturing process
they are1. PREMIUM - PURPLE
2. PREMIUM PLUS – GOLD
3. SUPREME - BEIGE
www.indiandentalacademy.com
31. PREMIUM GRADE
They are more difficult to bend, occasional breakage
to be expected.
They are efficient to open the bite.
PREMIUM PLUS
The 0.014 premium plus wire is used
in high angle cases to prevent
undue molar extrusion and due to
less dia.donot produce much force
and and ant intrusion(not effective)
which is favourable in such cases.
www.indiandentalacademy.com
32. SUPREME
Supreme grade wires are used to unravel crowding
of ant. teeth,maa,mini uprightining springs
They have resistance and yeild diameter near to
NI-TI wires and cost wise they are more economic.
when used as MAA the lighter forces produced do
not tax the anchorage.
www.indiandentalacademy.com
33. Triangular Wire
The new stainless steel Tri-Angle wire is an
equilateral triangle in cross-section, .030" to a side,
with rounded edges.
One of the best uses for Tri-Ang
wire is in retainers and other
removable orthodontic appliances.
Various types of clasps made of round wire usually
cross the occlusion, creating interferences that can
cause patient discomfort.
www.indiandentalacademy.com
JCO,2001 BY - BROUSSARD
34. The round wire can act as a wedge to cause
inter-proximal spacing, which can disrupt the
occlusion, with a potentially adverse effect on longterm stability.
Comfort , periodontal health, and appliance stability.
www.indiandentalacademy.com
36. NICKEL TITANIUM WIRES
Andersen G.F and co workers introduced the
use of NITI alloys for orthodontic use in 1970s
It consists of conventional NITI (55% nickel
45%titanium) ,resulting in 1 : 1 ratio of these
elements,cobalt is added to achieve desirable
properties.
www.indiandentalacademy.com
37. UNIQUE PROPERTIES
Shape memory effect - The combination of
thermoelasticity and pseudoelasticity in which,
following a force-induced phase transformation, the
reverse transformation occurs, when the archwire
temperature is increased to oral temperature
Pseudoelasticity - The mechanical analog of
thermoelasticity in which, at constant temperature,
the austenitic-to-martensitic phase transformation
occurs with increasing applied force. As the force is
subsequently removed, the reverse phase
transformation occurs.
www.indiandentalacademy.com
38. Thermoelasticity - The thermal analog of
pseudoelasticity in which the martensitic phase
transformation occurs from austenite as the
temperature is decreased. This phasetransformation
can be reversed by increasing the temperature to its
original value.
Phase transformation temperature –
1. Martensitic- on cooling ,Ms and Mf temperature are
the temp. at which the transformation to martensite
begins and is completed.
www.indiandentalacademy.com
39. 2.Austenitic- On heating As and Af are temp. at
which the transformation to austenite begins and
Compeleted.
3.Rhombohedral- It is a intermediate R-phase which
is formed during Martensite-Austenite phase, it also
has Rs and Rf phase.
www.indiandentalacademy.com
40. SUPER ELASTIC WIRES
Nitinol wire is work hardened during the
manufacturing process which induces the martenistic
phase into the alloy hence super elasticity is not
exhibited by the nitinol wire.
The super elastic property of some niti wires has
been attributed to phase transformation from
Austenitic form to Martenistic form of niti when stress
reaches certain level during activation.
www.indiandentalacademy.com
41. Upon deactivation the reverse phase
transformation from martenistic to austenitic
structure takes place.
It is thus necessary for the manufacturer to
leave ni-ti in austenitic structure for super elastic
behaviour.
The new super elastic ni ti (a-ni-ti) wires are
significantly different from earlier work hardened ni
ti(m-ni-ti)and from s.s
The combination of super elasticity and shape
memory makes these archwires comfortable for
the patients even as rect. intial arch wires.
www.indiandentalacademy.com
42. Since the stiffnes increases and the wire
becomes more efficient towards the end of the
movement the clinician should not change the
wire too often,a two month appoint. interval is
sufficient or remove and place the same arch
wires at monthly interval which will return them
to their intial activation level.
Intial rect super elastic wires fully engaged for
rotation correction, alignment,levelling.
www.indiandentalacademy.com
43. The original super elastic arch wires ,the round
sentalloy wires are available in light,medium,and
heavy force levels.
Neo-sentalloy wires at levels of 100,200,300
grams of forces.
The second generation ,squre or rectangular bio
force wires provides 80 gm of force in central
incisor region for tooth alignment and as much as
320gm of force in molar region for initial leveling.
www.indiandentalacademy.com
44. The new bio force ion guard has 3micron
nitrogen coating that is produced by ion
bombardment of wire surface which reduces
friction, breakage and nickel release.
The most versatile wire of simultaneous
alignment and leveling.
www.indiandentalacademy.com
45. CHINESE NITI
In1985 dr. burstone c.j. reportedof an alloy the
chinese ni-ti developed by dr.tien hua chang.
This alloy has unique charecteristics and offers
significant potential in the design of orthodontic
appliances.
It has low TTR than nitinol its history of little work
hardening in a parent phase which is austenitic
yield mechanical properties that differ significantly
from nitinol.
www.indiandentalacademy.com
47. Because of this high range of action and spring
back chinese ni-ti is applied when large deflections
are required.
It has sprinback that is 4.4 times more compared
to stainless steel and 1.6 times that of nitinol.
Stiffness of this wire is 73%that of s.s and 36% that
of nitinol.
These wires are highly suitable if low stiffness is
required and large deflections are needed.
www.indiandentalacademy.com
48. JAPANESE NITI
In 1986 miura f.etal reported Japanese NITI
,developed by furukowa electric comp.ltd. japan.in
1978
It posses excellent spring back ,shape memory
,super elasticity.
The delivered a constant force over an extended
portion of deactivation range and less likely to under
go permanent deformation.
www.indiandentalacademy.com
49. It generates a physiological tooth movement bcoz of
relatively constant force delivered for a long period of
time during the deactivation of the wire
This super elasticity can be produced by stress and
not by temp.difference
Heat treatment at 500deg centigrade for 5 minutes
produced optimum super elasticity,this method is
inconvenient for clinical use
So, anew type of heat treatment reported by fujio
miura which is known as derht(direct electric
resistence heat treatment)
www.indiandentalacademy.com
50. The chinese ni-ti and japanese ni-ti have a basic
austenitic grain structure and have a advantage of
transition in the internal structure with out
requiring a significant temp. change to accomplish
this.
www.indiandentalacademy.com
54. In 1993, Hanson combined the mechanical
advantages of multistranded cables with the
material properties of superelastic wires to create a
superelastic nickel titanium coaxial wire.
This wire, called Supercable, comprises seven
individual strands that are woven together in a long,
gentle spiral to maximize flexibility and minimize
force delivery.
JCO 1998 ,BY- JEFF BERGER
www.indiandentalacademy.com
55. FORCE DELIVERY TEST
A three-point bending test was carried out to
compare the force delivery of .016", .018", and .020“
Supercable with that of common nickel titanium
initial archwires.
Instron universal testing machine was used for
load deflection test.
All arch wires were loaded with a maximum
deflection of 4 mm, and then unloaded slowly
www.indiandentalacademy.com
56. STUDY RESULTS
.016" and .018" Supercable wires exerted only
36-70% of the force of .014" solid nickel titanium
wires.
Comparing wires of the same diameter, .016"
Supercable demonstrated 65% less force than .
016" solid superelastic wires
while .018" Supercable exerted 78% less force
than .018“ solid superelastic archwires.
www.indiandentalacademy.com
57. CLINICAL USES OF SUPER CABLE
.016" and .018" Supercable wires were the only
ones that tested at less than 100g of unloading
force over a deflection range of 1-3mm.
Supercable thus demonstrates optimum orthodontic
forces for the periodontium, as described by Reitan
and Rygh.
www.indiandentalacademy.com
58. Relatively large archwire like 0.18” can be placed
at the starting of treatment.
When cutting Supercable, always use a sharp
distal end cutter (No. 619). A dull cutter tends to tear
the component wires and thus unravel the wire
ends.
END STOP
www.indiandentalacademy.com
59. ADVANTAGES
• Improved treatment efficiency.
• Simplified mechanotherapy.
• Elimination of archwire bending.]
• Flexibility and ease of engagement regardless of
crowding.
• No evidence of anchorage loss.
www.indiandentalacademy.com
60. • A light, continuous level of force, preventing any
adverse response of the supporting periodontium.
• Minimal patient discomfort after initial archwire
placement.
• Fewer patient visits, due to longer archwire
activation.
www.indiandentalacademy.com
61. DISADVANTAGES
• Tendency of wire ends to fray if not cut with sharp
instruments.
• Tendency of archwires to break and unravel in
extraction spaces
• Inability to accommodate bends, steps, or helices.
• Tendency of wire ends to migrate distally and
occasionally irritate soft tissues as severely crowded
or displaced teeth begin to align.
www.indiandentalacademy.com
62. It is a new orthodontic wire designed by M.F.TALASS
It has high esthetic apperance with unique mechanical
properties. (manufactured by ORMCO)
It is made of clear optical fiber, it comprises 3 layers
1. A silicon dioxide core that provides the force for
moving teeth.
JCO,1992 BY- M.F.TALASS
www.indiandentalacademy.com
63. 2. A silicon resin middle layer that protects the core
from moisture and adds strength.
3. A stain-resistant nylon outer layer that prevents
damage to the wire and further increases its strength.
The wire can be either round or rectangular and is
manufactured in various sizes.
www.indiandentalacademy.com
64. Mechanical properties
It has wide range of action and the ability to apply
light, continuous force.
Sharp bends must be avoided, since they could
fracture the core.
Optiflex has practically no deformation.
www.indiandentalacademy.com
65. It is a highly resilient archwire that is especially
effective in the alignment of crowded teeth.
Optiflex possess 5 advantages, in terms of
esthetics
Optiflex is the most esthetic orthodontic arch wire.
Optiflex is completely stain resistant. The arch
wire will not stain or loose its clean look even after
several weeks in the mouth.
www.indiandentalacademy.com
66. optiflex is very effective in moving the teeth using
light continuous force. It exerts about ½ the
force in comparison with other wire.
Optiflex is very flexible and can be used in severely
crowded teeth.
Due to its superior mechanical properties, optiflex
can be used with any bracket system.
www.indiandentalacademy.com
67. When using optiflex, certain precautions
should be undertaken
Optiflex arch wires must be tied into the bracket
with elastomeric ligatures. Metal ligatures should
never be used since they fracture the glass core.
Sharp bend similar to those placed in metal
arch wire should never be attempt with optiflex.
These bends will immediately fracture the core.
www.indiandentalacademy.com
68. It is recommended to use the (501) mini distal end
cutter. (AEZ) This cutter is especially designed to cut
all 3 layers of optiflex in the proper manner.
Inform your patient about the nature of optiflex and
its structure.Make sure they understand that rough
diet can harm the arch wire and delay treatment
progress.
Do not “cinch back” optiflex. You really don’t need
an cinch back since friction between elastomeric
ligatures and the outer surface of the arch wire will
eliminate unwanted sliding of the arch wire.

69. Clinical applications
It is used in adult patient who wishes that their
braces not be really visible for reason related to
personal concern or professional consideration.
It should be used in non-extraction cases as, it is
not the ideal wire for cuspid retraction in extraction
cases
optiflex has been disappointed in retracting
canine due to its limited ability to control the distal
tipping and labio lingual rotation of the retracted

cuspids.
70. Optiflex can be used in pre-surgical stage in cases,
which require orthodontic intervention.
Optiflex arch wire combined with translucent
brackets to create ultimate esthetics appliance.
Optiflex is available in 6 to 10 inch straight lengths of
0.017”and 0.021”
Optiflex arch wire showed low load deflection rates
reaching the proportional limit much earlier when
compared to other wires (braided stainless steel, niti,
cooper niti), It exerts 0.4698 grams for a defection of
4.46 mm.

74. organic polymer retainer wire made from 1.6mm
diameter round polytheline terephthalate.
This material can be bent with a plier, but will
return to its original shape if it is not heat–treated
for a few seconds at temperature less than 230°C
(melting point).

75. In prefabricating the QCM retainer wires, the anterior
portion of the wire and the “wave” portion are
heat-treated at about 150°C immediately after bending.
Patients who have worn esthetic ceramic or plastic
brackets during orthodontic treatment are likely to
want esthetic retainers after treatment, so these wires
are used for esthetic maxillary retainers
Various parts of QMC retainer

76. Wire after heat-treated it displayed little deformation.
More shrinkage during heating was observed in the
posterior segment of the arch wire.
