COMPONENT MEETING SUMMARY THE LATEST TRENDS IN ORTHODONTIC TREATMENT: PART I Presented by Dr. William Proffit, Arizona State Orthodontic Association, December 2014. Summarized by Dr. Jae Hyun Park, PCSO Bulletin Editor. Editor's Note: The Arizona State Orthodontic Association (ASOA) held its 2014 Annual Meeting at the Phoenix Country Club in December, with Dr. William Proffit as the guest speaker. His lecture was entitled "The Latest Trends in Orthodontic Treatment and the Science Behind Them." Because this was an all-day lecture that presented very valuable information, I have decided to summarize and share it with our members. The second part of this lecture summary will be included in the Fall 2015 issue of the PCSO Bulletin. gy, straight wire appliances, NiTi and TMA archwires, self-ligating brackets, and most recently, CAD/ CAM methods. SureSmile™ is an example that illustrates the concept that chair time for doctors and treatment duration may actually be inversely related. In a study from University of Indiana, the same doctor's outcomes with SureSmile versus conventional edgewise were compared. Treatment time with Drs. Park and Proffit SureSmile was faster, but root positioning was not as precise,1 which suggested that any time-saving may have been affected by the doctor's decision as to when treatment was satisfactorily completed. In a report on SureSmile use at University of Minnesota,2 Larson et al. emphasized effectiveness in the form of more precise finishing, not faster treatment. Although a preliminary report on Insignia treatment time emphasized that the cases were selected because they were not difficult,3 it has been cited in advertisements as evidence of faster treatment with these custom brackets. It seems the above tools are valuable for doctors from an efficiency standpoint, but they do not necessarily translate to shorter treatment times. Patient growth. Patient growth status has important implications here. Are we utilizing or attempting to direct the growth? If so, we need to treat our patients during adolescence, when they are still growing. For them, treatment time is determined largely by growth, and accelerated treatment methods are irrelevant. Faster treatment is largely a consideration in patients in late Biological responses. The hottest topic in terms of adolescence, and in adults, for whom shorter treatment accelerated tooth movement is the manipulation of the time may be more desirable from the patient's perspective. biological response to the orthodontic force system.

Dr. Proffit went on to explain Proffit reviewed each "new" advance in orthodontics, the piezo-electric signal generated during bone bending: illustrating that although these technologies have current flow through the alveolar bone causes a spike reduced chair time for doctors, they have not necesin bone bending, which physically distorts the electric sarily decreased treatment times overall.
