PHILOSOPHY: Preadjusted Straight Archwire By Diego F. Tatis, DDS THE ORTHOKINETIC Fig. 1a-c: A young man, 13 years old. Skeletal class II, with convex profile of soft and hard tissue. With dentoalveolar protrusión and dental proclination. With macrodontia concomitant with several crowding upper and lower. Treatment plan: Extraction of 14, 24, 34 and 44, Leveling, Retracction with máximum anchorage and Orthokinetics Mechanics and Retention. W ith the completion of the 1990s innovations in orthodontics involved, clearly defined goals oriented toward technological changes as a natural reflection of the technological development of biomaterials and metallurgy that was occurring. This lead to new materials for appliances, self-ligation, technological approaches to dental move-ment, etc. But little effort was made to find a solution to the historical shortcomings observed in the integral clinical practice of orthodontics. Namely in the prescription of brackets, simplified designs, biomechanics, and functional craniofacial inte-gration. In addition the development of protocols for diagnostics, therapy and the design of administrative and management platforms for the clinical practice, were important missed aspects. For these reasons, Dr. Tatis, after years of training and clinical testing of different techniques and treat-ment modalities, plus years of clinical practice, and basic clinical research applied with the highest stan-dards of scientific background, and laboratory experi-mental tests, arrived to the conclusions about the pros and cons of the historical antecedents of orthodontics evaluated with the rigor of scientific method. His conclusion demands an interdisciplinary approach to clinical practice to offer optimum outcomes in contemporary orthodontics by the so called ORTHOKINETIC PHILOSOPHY. ® This word derives from two etymologic components: Ortho from the Greek stem of orthos meaning “straight”, “true" and Kinesis also from the Greek meaning, “movement”, “motion”. In short, the basic idea consolidated in this new concept is the “dynamics of true movement in contemporary orthodontics”. The ORTHOKINETIC PHILOSOPHY ® and its approach is a new integrated view of orthodontic dynamics in the 4th dimension. Through a radical reduction of the level of force, time of treatment, biological cost and financial cost for the patient, we achieve the therapeutic goals of professional quality and excellence with “efficiency and efficacy through the principle of simplicity”. This is the first of three articles about the ORTHOKI-NETIC PHILOSOPHY ® . We talk about the fourth dimen-32 Spring 2016 JAOS
