The foregoing surely offer a range so broad that one may choose to address you from a number of viewpoints, such as that of an art, a profession, or a business. Since our colleagues in general dentistry credit the orthodontist with being a good business man, I might have selected the third definition as my topic, because I believe that the misunderstanding by the general practitioner of the orthodontic problem is due in large part to the failure of the orthodontist really to acquaint him with the science underlying the specialty as a basis for the art of its practice. Were he fully informed, he would not think orthodontics simple, its practice easy, and its earnings large. We could soon point out to him that, unhappily, some orthodontists have failed to meet their obligations, have had to discontinue special practice, and seek employment in other fields. I might also have chosen the second application and elaborated on those temptat.ions that lure orthodontists so that they “fail by losing flesh and waste away.” I fear, however, that were I to attempt this I should, as a personal exhibit, be laughed from the platform. I shall, therefore, direct you to the first definition, “that which is deficient, inadequate, or anything done imperfectly or attempted unsuccessfully.” Orthodontics, like any division of the health services, cannot always be wholly successful. There are too many variables to permit this. But it can, with increased knowledge and its dissemination especially among its own practitioners, reduce the number and extent of its failures. This the specialty has always striven to do and, may I say, not without success. When one contemplates that it is only forty years since so-called modern orthodontics had its inception, and this in a most modest beginning, there is no just cause for selfcriticism. In fact, I know of no branch of dentistry in which so much collateral fundamental science has been garnered and assimila.ted. This has resulted largely from the interest of scientists outside the field of our practice while most valuable and practical contributions have also been, and are now being, made from within our own ranks. The foremost cause for failures in practice, I feel, comes as a result of the inadequate facilities for orthodontic education which have prevailed until quite recently.
