  12. 12. 1903 - Dr. Anna Hopkins was elected the Society’s first secretary. She completed one of the early Angle courses, but was never to practice orthodontia. In 1906 she became Mrs. Edward Hartley Angle. www.indiandentalacademy.com
  13. 13. www.indiandentalacademy.com
  14. 14.  Angle’s influence on his students was profound  his teaching methods were most unorthodox  he made men learn through a rigid system of discipline. This covered every phase of their lives while they were under him, from the preparation of their assignments in theoretical subjects and the meticulous execution of their technical procedures to the menial housekeeping tasks of dusting and polishing their working quarters and even to sweeping the floors. www.indiandentalacademy.com
  15. 15.  His object was “to light the fire of ambition” in order that the student would develop to his highest potential.  His lectures often lasted 3 or more hours and were gems that were never to be forgotten.  Philosophy, literature and science- became as familiar to his students as the study of biology and force control in orthodontia. www.indiandentalacademy.com
  16. 16.  Angle felt that his students must have available the best sources of information possible.  restricted his own private practice to the treatment of malocclusion, thus becoming the first dental specialist.  He built up a faculty; among them were Milo Hellman, Raymond Osborn, Frederick Noyes and Albin Oppenheim. From them, they learned of tissue tolerance, the effect of mechanical forces on bone and tooth structure, and the physiologic and anatomic development of the dentofacial complex. www.indiandentalacademy.com
  17. 17.  1907 - moved his school to New York City.  1908 - found the school in New London, Connecticut.  1909 - the graduates of the New York and New London schools organized the Eastern Association of Graduates of the Angle School of Orthodontia  1913 - the students of Angle practicing on the Pacific coast formed the Pacific Coast Society of Graduates of the Angle School. www.indiandentalacademy.com
  18. 18.  ill health forced Angle to leave the East Coast  1916 - Dr. and Mrs. Angle settled in Pasadena  Angle determined to devote his time to study, invention, and experimentation and relaxation.  One room in the home was set up as a workshop, and it was here that Angle was his happiest – tinkering, improving, and creating some of the instruments for which he held 32 patents. www.indiandentalacademy.com
  19. 19. New school  In 1917, a young dentist James Angle who had once studied under the master appeared at the door of the Angle home.  He spread the news of Angle’s experience, and soon others applied for training  Thus did the 62-year-old Angle once again, and for the last time, take up teaching. www.indiandentalacademy.com

  23. 23.  Prior to admission, student was thoroughly grilled in the basic sciences, either by Dr. Angle or one of his staff.  The applicant was expected to know the anatomy, embryology and histology of the head and neck (exclusive of the brain), the growth, development, and functioning of the denture  He also expected the applicant to be reasonably familiar with history, general science, and English literature www.indiandentalacademy.com
  24. 24. Filing, soldering, and wire bending had to be mastered before the student was permitted to do any appliance manipulation. Only after surviving the rigors of discipline, theory, technique, and case analysis, the student was allowed admission to the clinic. www.indiandentalacademy.com
  25. 25.  They had no acrylics, no alginates, no light wires, no model trimmers and no preformed bands.  Impressions were taken in plaster and, because undercuts prevented removing the stony mass in one piece, the operator was obliged to score the material and pry it off, piece by piece.  The poured impression was later trimmed by hand with a plane, a saw, or a huge file. www.indiandentalacademy.com
  26. 26.  Angle tried to introduce licensure bill (license orthodontists separately from dentists)  but was unsuccessful in getting his licensure bill to pass the California legislature.  He did, however, live to see a similar bill, introduced by Charles Tweed, become law in Arizona. (The law was repealed six years later.) www.indiandentalacademy.com

  44. 44.  1926 - streamlined edgewise bracket soldered eyelets on mesial and distal to control rotations, paving the way to the twin brackets (Siamese brackets) of today www.indiandentalacademy.com
  45. 45. Angle’s last patent  belatedly filed almost 3 years after his death by his wife  The highly popular Broussard bracket of the 60s and 70s was based on this patent. www.indiandentalacademy.com
  46. 46. Other contributions  concern about the biological response to foreign bodies used in oral environment.  reflected in many of his patents in which he has constantly tried to cover all possibilities for adverse use or unfavorable reaction. www.indiandentalacademy.com
  47. 47.  Angle made an inventory of the available materials - gold, silver, platinum, platinous silver, iridio-platinum, platinoid, aluminum, brass, copper, aluminum bronze, steel, iron and vulcanized rubber.  he found that “the material most fitting was nickel silver,” a brass (copper-zinc alloy) that did not have any silver in it at all! www.indiandentalacademy.com
  48. 48.  He was largely self-taught, and yet he mastered complex metallurgy.  in one of his publications, he explains that pinching the arch “not only spreads the particles of metal, so as to increase the length of the rod, but tempers the part subjected to the pinching action, thereby largely compensating for the reduction in the area of the rod section at that point, and consequently maintaining the strength and rigidity of the rod under the longitudinal strain thereon.” www.indiandentalacademy.com
  49. 49.  His knowledge of noble metals is witnessed also by his use of gold and of platinum-iridium arches in orthodontics.  He was the first to use coil springs. But he connected them only to nobler metal arches www.indiandentalacademy.com
  50. 50.  1887 - introduction in orthodontics of both soldering and a “baser” alloy which contained 60% to 70% copper 10% to 20% zinc 10% to 15% nickel www.indiandentalacademy.com
  51. 51. Publications & Presentations  First scientific paper- "Irregularities of the Teeth" -at the ninth International Medical Congress.  Considered as the first edition of his textbook which was to go through seven editions  The seven editions of Angle’s book were published under the following titles  Irregularities of the Teeth, 1887 A System of Appliances for Correcting Irregularities of the Teeth, 1890  www.indiandentalacademy.com
  52. 52.  The Angle system of Regulating and Retention of the Teeth, 1892  The Angle system of Regulation and Retention of the Teeth- With an Addition of Treatment of Fractures of the Maxillae, 1895  Angle system of Regulation and Retention of the Teeth and Treatment of Fractures of the Maxillae, 1899  Malocclusion of the Teeth and Fractures of the Maxillae, 1900  Treatment of Malocclusion of the Teeth, 1907 www.indiandentalacademy.com
  53. 53.  1899 - “The Classification of Malocclusion” in the Dental Cosmos  His classification provided an intelligent and easily understood means of communication among members of the dental profession. www.indiandentalacademy.com
  54. 54.  Angle believed the maxillary first molars were the key to occlusion  The anterior-posterior position of the maxillary permanent first molars is relatively immutable  considered the upper first molar as the most reliable point of reference from which to compare other teeth  the eruption pattern of the maxillary permanent first molars causes them to assume a normal position. www.indiandentalacademy.com
  55. 55.  Subsequent investigations have shown that the A-P position of the permanent first molar is not constant in relation to the base of the skull.  Though Angle postulated tooth movements in three planes, the main focus of his classification was in one plane (sagittal) krogman www.indiandentalacademy.com
  56. 56. Angle - the environmentalist  Individual variation from structurofunctional harmony was due to faulty environment A Class II Div. 1 malocclusion – can be viewed as basically due to an underdeveloped mandible - in turn due to an environmental failure  So treatment must also be environmental, aiming at restoring normal function, to make up for an unachieved normal mandibular growth. www.indiandentalacademy.com
  57. 57.  Angle was aware of the fact that the orthodontic tooth movement involved a feedback situation in which tooth and bone reacted reciprocally.  Angle influenced by Julius Wolff - “Wolff’s law of bone” – bone trabeculae arranged in response to stress lines on the bone. www.indiandentalacademy.com
  58. 58.  Angle had an uncompromising position against extraction.  It was his credo that "the best balance, the best harmony, the best proportions of the mouth in its relation to the other features require that there shall be a full complement of teeth, and that each tooth shall be made to occupy its normal position— i.e., normal occlusion." www.indiandentalacademy.com
  59. 59. CASE/ANGLE CONTROVERSY  Originally, Case was a genuine admirer of Angle.  Angle attributed the origin of the use of intermaxillary elastics to Baker, while Case thought that he should have received that credit.  This led to charges and countercharges between them in 1903. www.indiandentalacademy.com
  60. 60.  The second point of contention—the question of the extraction of certain teeth as a means of treatment.  Case defended the discreet use of extraction as a practical procedure, while Angle believed in nonextraction. www.indiandentalacademy.com
  61. 61.  The climax of this conflict was a debate in 1911 at the annual meeting of the National Dental Association  the problem became a matter of calm and objective evaluation and respectful appreciation of various points of view, each of which has made its contribution to orthodontics. www.indiandentalacademy.com
  62. 62. August 11, 1930 Angle died at his summer home in Santa Monica  On  On November 17, 1930, 22 members of Angle Society of Orthodontia met in Chicago, with the purpose of carrying forward Dr. Angle’s ideals of orthodontia.  They decided to reorganize the society, and decided to begin the publication of the Angle Orthodontist. www.indiandentalacademy.com
  63. 63. Criticisms by Bernstein  Angle 1900. favored / did extraction treatment before  In Angle's sixth edition textbook, extraction treatments are shown and discussed  Angle changed his position to non-extraction due to the controversy with Calvin Case who did advocate extractions www.indiandentalacademy.com
  64. 64. Theodore Adler  Angle changed to non- extraction after 1900 because of : - introduction of intermaxillary elastics - and his invention of e-arch appliance www.indiandentalacademy.com
  65. 65. criticisms  Dr. Angle did great harm to many persons, and to orthodontics, at the same time he was making his many contributions. Bernstein  By all accounts Angle was a difficult man. He is reputed to have harbored much of the bigotry and some of the xenophobia of his time. Theodore Adler www.indiandentalacademy.com
  66. 66.  "He did not like the Germans. He was broadminded but he had prejudices.”  "He lost many friends, or at least he alienated them.“  "If people had heard the terms he used in regard to them he would have had still more enemies." Wuerpel www.indiandentalacademy.com
  67. 67.  Angle "could never take criticism or argument".  When his ideas were verbally attacked, he would call his attackers "fools.“ Frederick Noyes www.indiandentalacademy.com
  68. 68.  "E.H.A. was obviously a disturbed man, and his image has been built up, far beyond what he deserved"  "approach became a classic example of cultism and dogma."  "Case was more successful as a contemporary leader than Angle. Case was on the inside leading while Angle was the maverick. He resented Calvin Case.” Tom Graber www.indiandentalacademy.com
  69. 69. "So I turned to the first special course then being offered. Unfortunately, being a resident of St. Louis, where the course was then given, I was asked to sign a contract to locate elsewhere on completion of the instruction. Angle added: 'You know, Lischer, I can pick the flowers in my garden myself.‘ Lischer www.indiandentalacademy.com
  70. 70. “Angle possessed many of the personality qualities seen in geniuses. They can be difficult, demanding, and unforgiving. They tend to be so devoted to their field that they fail to develop other aspects of their lives. Angle seems to fit that category.” Robert Rubin www.indiandentalacademy.com
  71. 71. Angle's dedication to orthodontics  “it (orthodontics) was his religion and his god. He would sacrifice everything for its sake. He could only see his life and his work and his devotion in terms of orthodontia.” Wuerpel www.indiandentalacademy.com
  72. 72. Conclusion  Though Angle died 1930, his influence is still felt strongly in orthodontics.  Even his enemies recognized the many contributions made by Edward Hartley Angle. www.indiandentalacademy.com
  73. 73.  His pioneer efforts in orthodontic education, his contribution to orthodontic literature, and his developments of innumerable instruments and appliances are not the accomplishments for which he will be remembered.  Long after these have faded into history, Angle’s name will be associated with the onward march of biologic science and it will be realized how perceptive was the mind that could penetrate the empiricism of his day and proclaim the significance of normal occlusion. www.indiandentalacademy.com
  74. 74.  This established orthodontia as a science and it will remain Angle’s greatest monument.  Characteristic of the man was a remark made shortly before he died: “I have finished my work. It is as perfect as I can make it.” www.indiandentalacademy.com
