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.
This document discusses the genetics of various oral and craniofacial conditions. It begins by covering basic genetics terminology and principles. It then discusses the molecular genetics underlying embryonic development of the face, dental development, malocclusions, external apical root resorption, and cleft lip and palate. Recent advances discussed include genetic testing, gene therapy, and pharmacogenomics in relation to orthodontics.

This document appears to be a literature review or reference list for a presentation on cephalometric analysis and landmarks. It lists over 50 references analyzing sources of error in cephalometric radiographs and landmarks, including magnification, projection errors, identification reproducibility, and how these errors can affect orthodontic measurements and analysis. The references examine specific angles and landmarks like ANB, Frankfort horizontal, and the beta angle in assessing sagittal discrepancies.
The document discusses Ronald Roth's modifications to the Andrews Straight Wire Appliance philosophy and treatment approach. Roth started using the Andrews appliance in 1970 and later modified the bracket prescription based on his clinical experience. Some key differences between Andrews and Roth include Roth allowing more tipping of teeth initially and building overcorrection into the brackets to account for relapse. Roth also placed more emphasis on achieving a gnathological occlusion goal versus Andrews' focus on anatomical tooth positions. The document outlines Roth's bracket placement, prescription, and rationale for his modifications to the straight wire appliance.
Indirect bonding involves placing orthodontic brackets onto dental models or casts in the lab, then transferring them to the patient's teeth using transfer trays. There are several methods for indirect bonding, including the Thomas method using double sealant technique, Knights method bonding brackets directly to casts, and Sondhi's method using Bioplast trays. Indirect bonding provides more accurate bracket placement compared to direct bonding but requires extra lab time and carries risks of adhesive flash or bracket loss during transfer.

This document describes a new soft tissue cephalometric analysis tool developed from Arnett and Bergman's facial analysis philosophy. Forty-six adult models were used to create a cephalometric database. Key midface structures are marked using metallic beads on lateral cephalograms. Measurements are made of soft tissue and hard tissue landmarks relative to the True Vertical Line (TVL) to diagnose dentoskeletal factors, soft tissue components, facial lengths, TVL projections, and harmony of facial parts. Cephalometric treatment planning uses the soft tissue analysis to optimize occlusal and facial results through positioning of the incisors, moving the mandible, defining the maxillary occlusal plane, and assessing chin projection.
The document provides a historical overview of orthodontics from ancient times to the late 19th century. Some key points summarized:
- Ancient civilizations like the Greeks and Romans practiced early forms of orthodontics by binding teeth with wires and catgut.
- Major figures like Hippocrates, Aristotle, and Galen contributed early dental anatomy knowledge and descriptions of malocclusions.
- During the Renaissance, da Vinci, Vesalius, and Paré advanced understanding of dental and facial anatomy.
- In the 18th-19th centuries, pioneers like Fauchard, Fox, Greenwood, and the Americans Harris and Angell developed new appliances and treatment techniques, establishing the

This document discusses the three orders of tooth movement that can be achieved through bending orthodontic archwires: first, second, and third order bends. First order bends move teeth inwards/outwards and can be used for derotation. Second order bends tip teeth vertically and are used for anchorage. Third order bends torque individual teeth by twisting the wire. Special pliers can help perform specific bends, like step pliers for first order bends and rose pliers for third order torque bends. Proper bending technique is important to avoid wire fractures.

Finally, it discusses the specialties of orthodontics like preventive, interceptive, and corrective treatments.
Dentistry has a long history dating back 7,000 years when the first evidence of dental practices were seen. Throughout ancient times and the middle ages, dental treatments were generally rudimentary consisting of tooth extractions. In the 18th century, dentistry began to emerge as a distinct medical profession led by pioneers like Pierre Fauchard who published the first scientific book on dentistry. Major advances were then seen in the 19th century with developments like anesthesia, dental chairs, x-rays, and the founding of the first dental schools and professional organizations. The 20th century saw further innovations including new materials like stainless steel, plastics and bonding agents which transformed modern dentistry.
Dentistry has a long history dating back 7,000 years when the first evidence of dental practices were seen. Throughout ancient times and the middle ages, dental treatments were rudimentary with "tooth worms" believed to cause decay and extractions the main procedure performed. The 1700s saw important developments like the first dental forceps and the recognition of dentistry as a distinct medical profession. The 19th century brought advances in anesthesia using nitrous oxide and ether as well as the commercial production of porcelain teeth. The modern era of dentistry began in the late 19th/early 20th century with the discovery of x-rays, innovations in dental materials like amalgam and the founding of major dental organizations worldwide.

Use of modified tooth forms in complete denture occlusion / dental implant...Indian dental academy
This document discusses dental occlusion concepts and philosophies for complete dentures. It introduces key terms like physiologic occlusion and defines different occlusion schemes like balanced articulation and monoplane articulation. The document discusses advantages and disadvantages of using anatomic versus non-anatomic teeth for complete dentures. It also outlines requirements for maintaining denture stability, such as balanced occlusal contacts and control of horizontal forces. The goal of occlusion for complete dentures is to re-establish the homeostasis of the masticatory system disrupted by edentulism.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
Temple of Asclepius in Thrace. Excavation resultsKrassimira Luka
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).

comprehensive data on root
resorption.
Became one of Angle’s “enemies”
when he modified Angle’s
appliances
www.indiandentalacademy.com
50. Isaac B. Davenport in 1881 developed a theory that
the masticatory apparatus was subject to the laws of
nature, that imperfect occlusion was deleterious to the
dentition ,that extraction of teeth in the treatment
could affect the efficiency of the masticatory
apparatus.
Henry A. Baker is remembered because in 1893 he
introduced the so-called Baker anchorage , or the use
of intermaxillary elastics with rubber bands .
www.indiandentalacademy.com
51. Eugene S. Talbot was equally proficient in
periodontics & orthodontics. He stressed the
study of the causes of malocclusion to be the key
to the treatment .
He stated that “without the etiology of
irregularities no one can successfully correct
deformities”.
www.indiandentalacademy.com
52. The principles of resorption & deposition of
alveolar bone during tooth movement were
discussed by L.E.Custer in March,1881, at a
meeting of the Mississippi Valley Dental
Association in a paper entitled “Intermittent
Pressure :Its Relation to Orthodontia.”
In 1899 the ‘Items of Interest’ was the first dental
journal to devote a section of each issue to

www.indiandentalacademy.com
56. Introduced multiloop light force wire or
Begg’s technique in 1965
Wrote ‘Begg Orthodontic Theory And
Technique’ in 1965
Used titanium wires
www.indiandentalacademy.com
58. One of Angle’s last students graduated in 1928
Was more concerned with dental protrusions and
unsatisfactory facial esthetics.
Led him to begin extracting 4 premolars in certain
patients after initially following Angle’s
nonextraction dogma.
At the 1940 annual meeting of the AAO, Tweed
displayed 100 consecutive case records
representing patients initially treated
nonextraction and then retreated with removal of
the 4 first premolars.
Tweed’s criterion for facial balance was the
position of the mandibular central incisors, from
which developed the Tweed triangle (1936).
www.indiandentalacademy.com
59. His mechanics involved a rigid, time-
consuming orthodoxy, and terms such as
anchorage preparation, tip-back bends, and
en masse movements
In 1947 formal courses of instruction, initially
called the Tweed Course, and from these
developed the Charles H. Tweed Foundation for
Orthodontic Research
Tweed Technique
He was the first person to use edgewise appliance
in conjunction with extraction & this treatment
method has been the Classic Edgewise Technique
for many years.
www.indiandentalacademy.com
60. History Of Brackets
Brackets were first used by Angle in ribbon arch
appliance (used self made stamped brackets of
soft gold)
Alloys of gold
Stainless steel in 1920 by Harry Brearly &
Sheffield F.M . Becket of US
Universal bracket by Spencer R Atkinson in 1929
www.indiandentalacademy.com
61. The gingival wire was
designed for mesiodistal
movements and extrusion-
intrusion, occlusal wire
could be used for rotations
and buccolingual
movement.
Atkinson donated all profits
from its sale to the
California Institute of
Technology and refused to
allow his name to be
attached to it.
The machine shop that
milled the first brackets for
the universal appliance
gave rise to the West
Coast’s first orthodontic
supply house, Unitek
Corporation (UNIversal
TEChnique). www.indiandentalacademy.com
62. Joseph E. Johnson (1888-1969)
Twin wire
Both wires were inserted
into the same channel,
which was fastened with
either a ligature wire or a
special cap .
Technique was effective at
leveling and rotating &
more comfortable, it lacked
control of the canines and
the premolars (they were
seldom banded) and was
unsuitable for extraction
cases

Appliances
Fredriech Christoph Kniesel first to give
removable plate in 1836
Coffin Plate – plate with spring in 1881
Victor H. Jackson (1850-1929) wire crib in
1887 to which were soldered a number of
finger springs for tooth movement. Most
appliances were made of steel piano wire or
“nickel silver,” an alloy of copper, nickel, and
zinc. His technique became known as the
“Jackson System”
www.indiandentalacademy.com
70. C. R. Coffin embedded spring-action piano wire,
bent into shape of “W,” into vulcanite plate,

• Kingsley’s anterior inclined plate in 1880
• Hotz devised a ‘Vorbissplatte’ a modified
form of Kingsley’s plate
• Pierre Robin introduced monobloc in 1902-
forerunner of all functional appliances
• It was designed mainly for patients with
glossoptosis syndrome (ectomorphic
constitution, adenoid facies, mouth
breathing, high palate) called the Pierre
Robin Syndrome
www.indiandentalacademy.com
75. Alfred .P.Rogers known as the father of
myofunctinal therapy
Advocated muscular exercises to improve
neck, head, tongue posture & encouraged
nose breathing

76. Viggo Andreson(1870-1950)
In 1908 in his daughters fixed appliance
placed a Hawley-Type of maxillary retainer &
a lingual horseshoe flange in mandibular
teeth
Called it biomechanic working retainer
On nighttime wearing it had eliminated class
II malocclusion & was stable
Andresen teamed up with Haupl in Norway to
write about their appliance & called it
Activator because of its ability to activate
muscle force
www.indiandentalacademy.com
78. In this only one wire element-labial arch for
upper anterior teeth
Coffin spring was added for expansion
In 1957 Eschler modified labial bow that
improved intermaxillary effectiveness (one
part was active other passive)
Two types of modifications-
Reduced in anterior palatal region called open
activator by Klammt in 1955
Reduced alveolar regions & with cross palatal
wires
www.indiandentalacademy.com
79. Some consist of two parts (upper & lower)
joined with wire bows
Muscle impulses are reinforced by wire
elements in the design eg Schwarz
modification
Stockfisch developed modern version with
an elastic activator & a semidouble plate
appliance

80. Vestibular screen by Newell in 1912
The Bimler Appliance
By Hans Peter Bimler (1916-2003)
Devised maxillary splint for patient who lost
his left gonial angle which guided the
remainder of his mandible.
Bimlers appliance after modification in 1949-
reduced size, elastic, upper & lower parts
connected with wire
www.indiandentalacademy.com
81. Double plate by A. Martin Schwarz(1887-1963)
Combined the advantages of the activator &
the active plate by constructing separate
mandibular & maxillary acrylic plates
Resembled monobloc or activator in two
pieces
Propulsor by Hans Muhlemann in 1952 based
on Activator
www.indiandentalacademy.com
82. A. Martin Schwarz was one of first to separate
activator horizontally, proginator of today’s Twin-
block.
www.indiandentalacademy.com
83. Harold .D. Kesling(1901-1979)
Developed tooth positioner in 1944
Made out of rubber
Could also be used as retainer
Later other materials were also used eg clear
plastics
Because of these innovations TP (Tooth
Positioner) orthodontics exists

84. Harold D. Kesling, inventor of tooth positioner.
www.indiandentalacademy.com
85. Bionator by Wilhelm
Balters(1893-1973)
Modified Andresen’s activator in 1950 to
treat class II malocclusions characterized by
deficient mandible
Consists of two halves connected with coffins
spring
Highly depends on patient compliance
www.indiandentalacademy.com
86. Rolf Frankel(1908-2001)
Recognized as inventor of an appliance that
corrects malocclusions with little or no
contact with dentition
Recognized that stability of treatment can
occur only if the structural & functional
deviations of the muscular system are
corrected
Designed the functional regulator in 1957

88. History of Head Gear
1802-Joseph Fox uses chin cap to skull cap
185o- Norman Kingsley first used occipital
head gear for retracting teeth
1947-Silas Kloehn introduced facebow with
cervical straps removing the ‘stigma’ of
victorian caps
www.indiandentalacademy.com
89. Amos Westcott used chincup in 1840s to treat
Class III patients.
www.indiandentalacademy.com
91. Cephalometrics
In 16th
century Durer & DaVinci sketched
series of human faces with straight lines
joining homologous structures
Anthropologists invented craniostat
facilitated standardized measurements-did
not allow study of living humans
Boon after discovery of X-rays by sirWilliam
Conrad Roentgen in 1895
www.indiandentalacademy.com
92. First paper by Pancini in 1922 which is now
called cephalometrics
Produced the concepts of standardized
graphic head images
In 1931 Hofrath in Germany & Broadbent in
US refined the technique given by Pancini
applied it to orthodontics
www.indiandentalacademy.com
93. cephalometric analysis introduced by William
B. Downs in 1948.
Its significance of that it presented an
objective method of many factor underlying
malocclusion & their could be a variety of
causes of malocclusion exclusive of teeth.
Other analysis were presented by C.C. Steiner
(1896-1989)in 1953 ,C .H Tweed 1953, S.E.Coben 1955,
R.M. Rickets 1966, V.Sassouni 1969, H.D. Enlow 1969,
