A new treatment system called ‘Biocreative Orthodontic Strategy (BOS)’ developed by Dr Kyu-Rhim Chung at 1979 to implement independent target teeth/bone/soft tissue movement while avoiding extending unnecessary orthodontic appliances to non-target segments during the orthodontic treatment period. In BOS, clinicians approaches patients with the following ten key principles:

- Tripod principle;

- Airway, a big deal;

- Keep an eye on growth;

- E=MC2;

- Alveolar bone boundaries;

- Condylar therapeutic position;

- Target tooth and bone movement;

- Importance of fewer TADs;

- Observe tongue posture;

- No tooth-borne expander for rapid palatal expansion.

These principles are called as `TAKE ACTION,` which is an acronym of each principle. In the patients who have anatomic limitation such as root resorption, bone loss, extremely thin alveolar bone around the teeth, various cortical activation methods guarantee the more effective treatment outcomes than conventional methods. In this three hours presentation, I will introduce this `BOS` treatment concept, treatment effects and simple and innovative way for correcting border line orthodontic cases without orthognathic surgery such as severe anterior openbite, occlusal canting, posterior occlusal collapse, and serious anatomic complexity through update scientific researches and excellent case reports. Audience members will learn specific clinical tactics and overall treatment protocols that will broaden their scope of treatment options.
