Tooth movement in orthodontic treatment is achieved by a combination of mechanical and physiologic forces acting on the teeth and their supporting structures to effect the biologic changes that cause teeth to move through bone. Traditional orthodontic appliances using wires, springs, and elastic forces inevitably cause some degree of discomfort and pain. In the present study, a new magnetized edgewise bracket was designed. The magnet works to move teeth mesiodistally and is not merely a mechanical force. It is well adapted to the biophysical system of tooth and bone interrelationships. Therefore, it works effectively, gives less discomfort, and produces less stress for the patient. The new magnetic appliance provides a force system that approaches the ideal orthodontic requirements.
正畸治疗中的牙齿移动是通过作用于牙齿及其支持结构的机械力和生理力的组合来实现的，以引起导致牙齿在骨中移动的生物学变化。使用钢丝、弹簧和弹力的传统正畸矫治器不可避免地会引起一定程度的不适和疼痛。在本研究中，设计了一种新型磁化方丝弓托槽。磁体的作用是使牙齿近远中移动，而不仅仅是一种机械力。它很好地适应了牙齿与骨骼相互关系的生物物理系统。因此，它效果显著，给患者带来的不适更少，产生的压力也更小。这种新型磁性矫治器提供了一种接近理想正畸要求的力系统。
