Update 2019: Asymmetry in Orthodontics

Mastering the Most Underdiagnosed Aspect of Orthodontics

As orthodontic providers, we often focus on improving patients’ antero-posterior (A/P) situation, but often overlook the asymmetrical aspect of the case. Because we’ve gotten so good at treating the A/P, our most common mistakes in orthodontics occur now because of asymmetry. Even the best orthodontists, practitioners, and instructors find that asymmetry is an area that they’ve misdiagnosed or overlooked. This Update Seminar will give you new tools to help you avoid making some of the most common orthodontic mistakes.

David Dana Asymmetry Protocol Looking at Frontal Ceph

When Dr. David Dana and Dr. Donald McGann looked over their finished cases, they realized that the work they were least happy with often had some sort of undiagnosed asymmetry. Always seeking to improve his and his community’s work, Dr. Dana dedicated himself to research. In the past decade, he looked at the newest developments in symmetry and occlusion, studied cases around the world, and worked closely with the top POS instructors to put together this Update Seminar. He has designed a more complete and refined asymmetry protocol, and looks forward to sharing it with you.

POS’ New Asymmetry Protocol will give you step by step detail on how to diagnose, plan and treat all orthodontic patient types better. This seminar will help you get a clear cut diagnosis plan on every case with asymmetry. By thoroughly understanding and diagnosing asymmetry, you will reduce mistakes, inefficiencies and headaches, and get better results.
