This document provides information on various non-patient compliant fixed functional appliances used to treat Class II malocclusions, including the Herbst appliance, MARA, Advansync, and fixed twin block. It discusses the history, design, advantages, disadvantages, and effects of each appliance. In general, these fixed functional appliances can eliminate patient compliance issues compared to removable appliances, have continuous effects, and shorter treatment times, but may have higher breakage and mechanical dislodgement risks.
Orthodontic brackets are components bonded to teeth that transfer force from archwires to move teeth into proper alignment and function. There are various bracket designs that differ in material, size, shape, and prescription. The development of pre-adjusted edgewise brackets aimed to directly guide teeth into normal occlusion with fewer bends in the archwire. However, individual variations still require some adjustments to achieve ideal positioning. Modern bracket types include self-ligating, ceramic, and lingual systems that offer enhanced aesthetics, mechanics, or patient comfort.
This document provides an overview of orthodontic treatment mechanics using the McLaughlin, Bennett and Trevisi (MBT) bracket system. It discusses the history and development of the MBT system, variations in appliance specifications including bracket selection and torque specifications. It also covers important aspects of treatment including bracket positioning, arch forms, anchorage control, archwire sequences and finishing the case.
Dr. Percival Raymond Begg developed the Begg technique for orthodontic treatment over many years, beginning in the 1920s. He studied under Dr. Angle and was an early user of the Edgewise appliance. Through his own practice, Begg realized some limitations of Angle's methods and made modifications like removing teeth or stripping tooth width to improve outcomes. This evolved into the Begg technique using light wires and brackets to minimize forces and reduce relapse. The technique gained popularity after visits by American orthodontists to Begg's practice and demonstrations of its effectiveness.
This document provides an overview of self-ligating brackets in orthodontics. It discusses the history of self-ligating brackets dating back to 1935. It distinguishes between active and passive self-ligating brackets and describes their mechanisms. The advantages of self-ligating brackets include lower friction, reduced treatment time, and better infection control compared to conventional brackets. However, some argue they have less control of minor tooth movements in later stages of treatment. Overall, the document provides a comprehensive review of self-ligating bracket types, features, advantages, and limitations.
TMA is an archwire material that is intermediate in stiffness between stainless steel and nickel titanium. It has good flexibility and springback along with predictable moderate forces that provide consistent tooth movement. TMA can be used in all stages of treatment but is especially useful as a main working archwire due to its properties. It is formable, weldable, and delivers approximately half the force of stainless steel.

Recent advances in Orthodontic archwiresmohan prasath
1. Recent advances in orthodontic archwires include multistranded wires, titanium alloys like titanium niobium, and nickel titanium alloys with varying properties like bioforce wires.
2. Newer archwire materials aim to deliver gentle controlled forces for improved patient comfort while achieving effective tooth movement.
3. Combination archwires incorporate sections of different materials like titanium and steel to provide flexibility in some areas and rigidity in others for better control of tooth alignment and anchorage.
The document discusses the Opus loop, a new orthodontic closing loop design developed by Raymond Siatkowski. It aims to deliver a consistent moment-to-force ratio (M/F) of 8-9 mm without adding residual moments. Traditional loops require residual moments via bends to achieve desired M/F ratios. The document outlines the theoretical basis for the Opus loop's design using Castigliano's theorem. Finite element analysis confirmed it maintains a consistent high M/F when positioned off-center. Experimental testing of prototypes verified the Opus loop achieves its intended M/F range, representing an improvement over other loops.
The document discusses the history and evolution of lingual orthodontics, describing the development of various lingual bracket systems from the 1970s to present. It covers key topics like patient selection, diagnostic considerations, bonding techniques, biomechanics, and keys to success with lingual therapy. Lingual orthodontics offers aesthetic benefits over labial appliances but also presents certain challenges in terms of treatment complexity and costs.

Edward H. Angle was a pioneering orthodontist who developed concepts of occlusion and malocclusion classification in the late 1800s. He opposed extracting teeth for orthodontic treatment. Several orthodontists further developed his ideas, creating new appliances like the Edgewise and Begg appliances to improve control of tooth movement and occlusion. In the 1970s, Larry Andrews identified characteristics of ideal occlusion from studying untreated ideal bites. He developed the preadjusted edgewise appliance and "Six Keys of Occlusion" to achieve optimal occlusion without wire bending. Ronald Roth built on Andrews' work by incorporating the temporomandibular joint.

Ni ion release of ti o2 and tio2 hydroxylapatite composite coatings formedIAEME Publication
This document summarizes a study that investigated the effect of TiO2 and TiO2/HA composite coatings on nickel ion release from porous NiTi shape memory alloy implants. Porous NiTi samples were produced by powder metallurgy and coated using H2O2 oxidation to form TiO2 and a combined H2O2/KOH treatment followed by immersion in simulated body fluid to form a TiO2/HA composite coating. Nickel ion release testing in saline solution found that TiO2 coating alone was insufficient to reduce nickel ion levels below safety thresholds, but the TiO2/HA composite coating was able to maintain lower nickel ion levels over time. The coatings were characterized using XRD to analyze phase composition.

Naval Ordinance Laboratory , MaryLand .
Nitinol- Ni for Nickel, Ti for Titanium, Nol for Naval
Ordinance lab.
Andresen introduced NiTi containing equal % Nickel &
Titanium.
www.indiandentalacademy.com
19. In 1986 two superelastic alloys (Japanese & Chinese)
which has active austenitic phase that forms stress
induced martensite.
In 1990 ’s a neo Sentalloy which is a true active
martensitic alloy having SME was introduced.

Strain resistant.
28. These wires provide light forces & are used during
initial aligning phase.
To prevent permanent deformation sharp bends should
be avoided.
www.indiandentalacademy.com
29. Stainless steel wires in orthodontics
Introduction:
Steel is an iron based alloy which contains less than
1.2% of carbon.
Chromium (12-30%) - added to steel, the alloy is
called stainless steel.
www.indiandentalacademy.com
32. Passivating effect of chromium:
When exposed to air , a thin transparent oxide layer
formed on the surface protects it against tarnish &
corrosion.
Nickel:
It helps to stabilize at low temperature.
Manganese, Nitrogen:
Stabilizes the structure.
www.indiandentalacademy.com
33. Molybdenum:
Increases corrosion resistance.
Pitting resistance equivalent (PRE), evaluate the
resistance of the alloy to pitting corrosion based on the
content of Cr, Mo, N
The higher the PRE value ,the less susceptible the alloy
is to pitting corrosion.
www.indiandentalacademy.com
34. Carbon content:
Low carbon content corrosion resistance.
Silicon:
Silicon at low concentration improves resistance to
oxidation.
www.indiandentalacademy.com
36. Disadvantages:
Soldering is demanding.
Lower spring back than Nickel titanium alloys.
High modulus of elasticity.
More frequent activations are required to maintain the
same force levels.
www.indiandentalacademy.com
37. Classification of stainless steel:
1.
2.
3.
4.
5.
6.
Classified according to American iron & steel institute
system(AISI).
Parallels the unified number system (UNS) & the German
standards. (DIN).
Austenitic steels.
Martensitic steels.
Ferritic steels.
Duplex steels.
Precipitation hardenable steels.
Manganese containing steels.
www.indiandentalacademy.com
38. Austenitic stainless steel:
At temperatures between 9120C & 13940C, a stable
form of iron is a face centered cubic structure ((FCC)
called Austenite.
18-8 stainless steel
Composition:
Chromium
18%
Nickel
8%
Carbon
0.08-0.15%
www.indiandentalacademy.com
39. Most corrosion resistant of all stainless steels.
Austenite has FCC structure which is unstable at
room temperature & turns to BCC structure.
If austenizing elements(Ni ,Mn &N) are added, then
stability can be maintained.
They are not attached by magnet.
www.indiandentalacademy.com
40. Advantages of Austenite
1. Greater ductility & ability to undergo more cold work
with out breaking.
2. Substantial strengthening during cold working.
3. Greater ease of welding.
4. Increased formability.
5. Ability to readily overcome sensitization.
www.indiandentalacademy.com
41. Applications of Austenite:
1. In orthodontics --- wires, bands, ribbons, hooks
bows & springs.
1. In prosthodontics --- partial denture clasps, bars.
2. Generally
--- instruments, burs, pliers
sterilizers , trays.
space maintainers
www.indiandentalacademy.com
42. Sensitization:
Loss of corrosion resistance of 18-8 stainless steel,
when heated b/n 4000C-9000C(temperature used during
soldering & welding ) is called sensitization.
This due to precipitation of chromium carbide at grain
boundaries.
www.indiandentalacademy.com
43. Stabilization:
Introduction of one or two elements that form carbide
precipitates in preference to chromium such as niobium.
Stainless steels stabilized in this manner are said to be
stabilized steels.
www.indiandentalacademy.com
44. Martensitic stainles steel:
When austenite (FCC) is cooled very rapidly
(quenched) , it will undergo transformation to a body
centered tetragonal structure called Martensite.
www.indiandentalacademy.com
45. Corrosion resistance of martensitic stainless steels is
less than other types.
High strength & hardness.
These are used as surgical & cutting instruments
because of its high strength & hardness.
www.indiandentalacademy.com
46. Ferritic stainless steel:
Pure iron at room temperature has body centered cubic
(BCC) structure called ferrite, stable at 9120C.
Super ferrites contain 19-30% chromium.
www.indiandentalacademy.com
47. Duplex steels:
Consist of combination of austenite & ferrite .
Not attracted by magnets.
When improperly heat treated, they have a tendency to
form a brittle phase (sigma) that diminishes their
corrosion resistance.
www.indiandentalacademy.com
48. Precipitation-Hardenable steels:
Hardened by heat treatment unlike other stainless steels.
Because of its high tensile strength ,used for mini
brackets.
www.indiandentalacademy.com
49. Manganese containing steels:
Manganese – used as replacement for nickel.
Manganese acts by dissolving the really austenizing
element , nitrogen.
www.indiandentalacademy.com
50. Multistranded wires
These are small diameter stainless steel wires twisted or
braided to form large diameter wires.
They may be
Round
based on cross section
Rectangular
}
3 strands
based on no.of strands
6 strands
}
Braided
based on mode of joining strands
Twisted
}
www.indiandentalacademy.com
52. Large elastic deflections & apply low forces compared
to stainless steel wires
Spring back similar to NiTi, but larger compared to
stainless steel & beta titanium.
www.indiandentalacademy.com
53. Australian wires
These are round high tensile stainless steel wires &
were introduced by A.J.Wilcock.
These are used during initial aligning phase.
www.indiandentalacademy.com
54. Grades of australian wires:

55. Higher yield strength of the newer grade wires
influence the following properties:
Working range, also called as maximum flexibility,
spring back of elastic strain:
Range ~
www.indiandentalacademy.com
YS
--------EM
57. Zero stress relaxation:
Ability of the wire to deliver a constant force over long
periods when subjected to an external load.
Formability:
For the same material, greater the resiliency lesser is
the formability.
www.indiandentalacademy.com
58. Banding
Banding involves the use of thin stainless steel strips
called bands that are pinched tightly around the teeth and
then cemented to the teeth.
It is preferable to band a tooth that
requires buccal as well as lingual
attachments.
Bands are better likely to resist heavy
forces as in the case of extraoral
devices such as head gears.
Steps in banding:
Separation of teeth.
www.indiandentalacademy.com
59. Selection of band material.
Pinching of the band.
Fixing the attachments.
Cementation of the band.
www.indiandentalacademy.com
60. Bonding
The method of fixing attachments directly over the enamel
using adhesive resins is called bonding.
The most accepted method is the pretreatment by
acid etching technique.
This technique was introduced in 1955 by
Buonocore.
The pretreatment of enamel by acid etch technique
helps in the following ways:
Enhances the surface energy .
Enhances the surface area and porosity.
www.indiandentalacademy.com
61. Advantages of bonding:
It is esthetically superior.
It is faster to bond than to pinch bands
around the teeth.
It enables maintenance of better oral
hygiene.
It is possible to bond on teeth that have
aberrant shapes or forms. It might be
impossible to band such teeth.
Disadvantages of bonding:
•Bonded attachments are weaker than banded attachments
and hence are more prone to bond failure.
• Bonding involves etching of the enamel with an acid which
may lead to enamel loss and an increased risk of
demineralization.
• Enamel fracture can occur during debonding.
www.indiandentalacademy.com
64. Brackets
Brackets act as handles to transmit the
force from the active components to the
teeth.
Edgewise type of bracket.
Ribbon arch brackets.
Weldable and bondable
brackets.
