Dr. Larson received his dental degree from the University of Minnesota in 1981, completed a general practice residency in the U.S Air Force in 1982 and practiced general dentistry until 1985. He received his Certificate and Master’s degree in Orthodontics from the University of North Carolina in 1987 under the mentorship of Dr. William Proffit. He spent 3 years as an orthodontist in the U.S. Air Force before joining the staff and faculty at the Mayo Clinic in 1990. At Mayo he served as Program Director in Orthodontics and received several “Teacher of the Year” awards. In 1996 Dr. Larson left Mayo for full-time private practice in Rochester, MN where he continues to practice 1 day a week. In 2004 he returned to full-time academics at the University of Minnesota where he currently serves as Professor and Director of the Division of Orthodontics. He has published many scientific articles, contributed book chapters, and given many lectures in the US and abroad. Most recently he has worked with Dr. Proffit on the 6^th edition of the Contemporary Orthodontics textbook.

Dr. Larson has received the Distinguished Dental Alumnus Award and Century Club Professor of the Year from the University of Minnesota. He is also the 2018 recipient of the Jarabak Memorial International Teachers and Research Award from the AAO Foundation given for significant contribution to orthodontic teaching and research.

Dr. Larson is active in organized orthodontic associations both locally and nationally. He is a Past-President of the Minnesota Association of Orthodontists, the Midwestern Society of Orthodontists (MSO) and currently serves as the 2018-2019 President of the American Association of Orthodontists (AAO). 

As 3D imaging has become readily available in dentistry, debate has taken place regarding its proper place in orthodontic diagnosis and treatment planning. This advanced imaging only has value if it provides additional information beyond what is obtained from traditional cephalometric and panoramic images. If the clinician intelligently uses the 3D volume rather than simply extracting conventional 2D images, there is significant additional diagnostic information from the advanced 3D imaging that can benefit the clinician’s diagnosis and ultimately the patient’s treatment. Demonstration of these concepts will be accomplished through case presentations.

Following this presentation, the participant should be able to:

1. Understand strategies for managing mixed dentition crowding using a non extraction approach and outline the limitations.
2. Describe Serial extraction with its advantages and disadvantages.
3. Recognize how to modify serial extraction for patients who have Class 2 malocclusions or missing teeth.

To recognize Dr. Moore’s commitment to research and education, graduate orthodontic students will present synopses of their research investigations on the following subjects:
