The meeting of the Southern Society of Orthodontia
“It. is preferable that applicants in Class 3 show they have had a yea:* of clinical experience in a general hospital following four years in a medical ~ch001 preliminary to special study of otolaryngology and service as ax{ ear, tiose and throat interne. “So examination will be given to applicants who have been in actual practice of otolaryngology for less than one year. ” FOPHL of Examination.--In determining the question of certification, the ttxaminers rely on the following criteria : The applicant’s professional record. Pwond: Written reports of the prescribed number of cases that he has observed and treated. Third : A practical, clinical, and la,boratory examination w\\-hen reqtljxd. Foudh : A written examination when required. Pit-d:
By unanimous approval the board had decided to certify those appliwhose professional records are such as to give them a national reputation, or preeminence in their communities, without a specific examination. The American Society of Orthodontists could also agree to such provision, as there are a number of men in the Society who because of work done in orthodontia in years of practice and clinical skill would be entitled to such certificate of proficiency. The American Board of Otolaryngology selects those men from a group who have pra.cticed fifteen years or more. The American Boa.rd of Orthodontists wo~dld render a valuable service to the public by examining and granting certificates to succrssful candidates. We believe that such a. board would have a much better influence upon improvement of orthodontia as a special branch of dentistry than al?y legislation that could be passed by a state or any pet plan of education that is advocated by certain schools, universities, deans and professors. ca.nts,
The Meeting
of the Southern
Society of Orthodontia
HE regular annual meeting of the Southern Society of Orthodontia was held at the Dempsey Hotel, Macon, Ga., January 30 and February 1 and 2. The meeting was presided over by the President, Dr. W. B. Chills. The program as provided by the Executive Committee was very interesting. Dr. Oren A. Oliver presented a paper on “Lingual Arch Technic.” DisOther members took cussion was opened by Dr. Harry Kelsey of Baltimore. part in the discussion. One of’ the most outstanding papers was presented by Doctor Mile Hellman of New Pork. The paper was the result of a large amount of research work that has been done by Dr. Hellman to establish the position of the Orbital Plane in the development and growth of the face, and as related to certain types of malocclusions. The essayist refuted the theories of Dr. Simon in reference to the Orbital Canine Law. He quoted from Dr. Simon’s works to show that Dr. Simon states that the posilion of the canine to the orbit was constant at all apes. Dr, He]]-
man showed that there was a difference in the rapidity of growth in the region of the canine and orbit whieh produced a variation at different ages. Dr. Hellman stated that in young patients the denture occupies a more posterior position to the orbit than it does in older patients. During the process of growth the denture travels downward and forward much more rapidly and the orbit changes position. Dr. Hellman also showed that the position of the canine as related to the orbital point, as mentioned by Dr. Simon in his Orbital Canine Law, varies with different races. This being the case, we would also expect the canine to vary with different types of faces. Dr. Hellman measured a number of skulls of different races in which the canine showed a range of variability as related to the orbital point in all of the skulls. In certain cases the canine and the entire denture occupies a more anterior position to the orbital point than it does in others. He measured a number of normal skulls, and skulls of posterior occlusion (Class II) of the same race, and it was found that skulls of posterior occlusion show that the maxillary denture occupies a position more posterior to the orbital pl.ane, than the position of the denture in skulls of normal occlusion. In fact, the posterior occlusion cases showed that the canine were as far posterior as the In other words, Dr. most extreme posterior position in normal occlusion. Hellman’s investigations failed to substantiate the opinion that in posteriol occlusion conditions or Class II cases, the maxilla is further forward tha,n it is in normal conditions. In fact, he stated that skulls showing posterior or Class II conditions indicate that the entire denture occupies a position further behind the orbital point than that, position found in normal ocelusiou. Not only is the mandibular arch posterior as related to the face and cranium, but the maxillary arch is posterior in many of the cases. During the process of dentition both the mandibular and maxillary arch travel downward and forward as related to the face and cranium. Dr. Hellman presented measurements made on his patients, extending over a period of years during treatment and retention, which proved that the dentures mere continually growing forward more rapidly than the orbital point moved forHe showed that the maxillary arch developed forward in poiterior ward. occlusion even when intermaxillary rubbers were used to stimulate forward growth in the mandibular arch. Dr. W. F. Quillian, President of the Wesleyan Female College, Macon, Ga., delivered an interesting address on the “History of Education. ” ‘“The Evolution and Anatomy of the Temporo-Mandibular Articulation as Related to the Different Types of Malocclusion” was the subject of an illustra.ted lantern talk by Dr. Martin Dewey. The discussion of the paper was opened by Dr. C. C. Howard who showed a number of slides and discussed the work done by Dr. A. LeRoy Johnson several years ago in the study of the Temporo-Mandibular Articulation. Dr. Dewey called attention to the fact that the Temporo-Mandibular Articulation and the parts associated therewith made it extremely improbable that t,he condyle was in an anterior or posterior position in either anterior or posterior occlusion, The misapprehension in relation to this fact arises from the lack of recognition of anatomic conditions.
The greater part of the deformit,y is located in t,he body of the ma,ndible, anterior to the attachments of the muscles of mastication. On Thursday evening a. dinner was held at the Hotel Dempsey. Dr. H. H. Johnson gave a talk on “The Influence of Specialization in Dentistry. ” Dr. A. H. Ketcham spoke of the accomplishments of the Committee on Arrangements regarding the meetin g of the American Societ,y of Orthodontists to be held at E$es Park in July. On Friday Dr. Lloyd S. Lourie of Chicago gave a paper entitled “Trimming Deciduous Teeth to Favor Normal Eruption of Permanent Teeth or Assist in Correcti&~~alocclusion. ” As is usual, Dr. Lourie’s paper was extremely practical, valugble and well proved by clinical facts. This paper was well received. Dr. A. H. Ketcham of Denver opened the discussion. Dr. Benjamin Bashinski, M.D., of Macon, gave a paper on ‘(Some Factors which Accelerate and Inhibit Growth in Children.” This paper was discussed bq- Dr. C. C. Harrold, also of Macon. A paper by Dr. T. Wingate Todd, Director of the Anatomical. Department of the Western Reserve University, showed that the face and cranium of lower It is animals developed along the same lines as was shown by Dr. Hellman. a8 remarkable’ fact that, two men working on different material regarding the growth and’development of the face should arrive at identical conclusions. Dr. Todd m&de measurements of different parts of human skulls of different races to show t,he rapidity of development in certain localities. He fou!ld t,hat the m.axillary arch swung downward and foqvard, which allowed for Ihe increase in size of the nasal pharynx. On Friday evening a dinner was given in honor of Dr. Hellman and Dr. Todd. Dr. R. Holmes Mason, of Macon, acted as toastmaster. Saturday morning was devoted to a business session and to case reports. Clinics were given by Dr. Lloyd S. Laurie, Chicago, Dr. Oren A. Oliver, Nashville, and Dr. Lowrie J. Porter, New York City. The next meeting will be held at Washington in 1930.
