ALIGNERS: A Biomechanical Perspective provides a focused exploration of the principles that govern clear aligner therapy. Blending foundational biomechanics with clinical insights, this book explains how aligners move teeth through controlled forces, material behavior, and strategic staging. It discusses the design of aligners, their limitations, and ways to enhance treatment efficiency and predictability. Intended for dental students, orthodontic residents, and practicing clinicians, it simplifies complex concepts while maintaining academic fineness. With clear explanations and practical relevance, this book serves as both an educational resource and a clinical guide for those seeking to understand the mechanics behind successful aligner therapy.
