In the past fifty years orthodontics has gone through three phases of development; first, the mechanical concept; secondly, the bio- logic concept; and today, a new phase — preventive orthodontics. This concerns the general dental practitioner more than the or- thodontist, as it is he who sees the patients at an early age. The general dental practitioner should be trained to recognize factors of growth and development, either accelerated or retarded; developing malocclusions; form and function; etiology of malocclusion; the function of the deciduous and permanent dentition; and in- dividual normal occlusion. He should realize his responsibility starts and not ends when a deciduous tooth is extracted prematurely or when a permanent tooth is extracted. He should have at his command the ability to cor- rect cross bites, interlocked incisors, to open up or close spaces, and to place space main- tainers where indicated. The intelligent application of known prin- ciples of diagnostic procedures by the general dental practitioner could prevent a third of all cases of malocclusions. orthodontia Arthur C. Totten. D.D.?
