Biphasic theory: breakthrough understanding of tooth movement

摘要: Abstract Background Research on the biology of orthodontic tooth movement has led to prevailing compression-tension theory, which divides response force into two opposing reactions spatially separated: compression side, osteoclasts resorb bone create space for movement, whereas tension osteoblasts form restore alveolar structure. Methods Here we take a critical look at literature how force-induced inflammation, periodontal ligament, osteoclasts, and contribute biological reaction force. We introduce new evidence that supports novel theory explain movement—the Biphasic Theory. Results The Theory Orthodontic Tooth Movement initial Catabolic Phase, during both sites, Anabolic occurs subsequently its pretreatment levels. Conclusions successfully addresses shortfalls in Compression-Tension Movement, provides clinicians with better understanding forces move teeth, offers targets therapies aimed accelerating movement.
