خرید و دانلود نسخه کامل کتاب Passive Self-Ligation from A to Z

The specialty of orthodontics is full of techniques and camps, each offering specific protocols to achieve the best results. The Damon System is different; it’s a philosophy that focuses on the why to get to the how, challenging orthodontists to think and reason their way to a successful finish. The philosophy is predicated on the notion that teeth treated with passive self-ligation (PSL) move faster than teeth treated with traditionally ligated brackets; the increased play between the slot and bracket reduces friction and enables greater movement, even with low forces. This low-force, low-friction system is also more biologically sound for the periodontal apparatus, which is good news for the patient and for treatment stability. This book is the how-to guide for PSL in orthodontics, from diagnosis to bracket placement to finishing—and everything in between.
