Our workshop covers all the information needed for attendees to successfully implement A1 TAD system procedures into their orthodontic practice. By the end of the workshop, attendees will be able to identify anatomical structures and the appropriate treatment options best fit for their patients and their case. Mini screws offer the opportunity for difficult biomechanical movements to be achieved in a simple, efficient, quick manner while still being safe.
