    • Orthodontic systems and related methods are disclosed for designing and providing improved or more effective tooth moving systems for eliciting a desired tooth movement and/or repositioning teeth into a desired arrangement. Methods and orthodontic systems include the generation of an overcorrection in the tooth-receiving cavities of an appliance worn in the dentition. The overcorrection may provide an improved and more accurately applied force or moment applied to a tooth. The overcorrected force or moment can move a tooth closer to a desired position than if not overcorrected as sufficient force can still applied to the tooth as it gets closer to the desired position. The overcorrected force or moment may also better target the root of the tooth where the biological response to tooth movement occurs. The overcorrection may be calculated in various ways as described herein.
    • 公开了用于设计和提供改进的或更有效的牙齿移动系统的正畸系统和相关方法,用于引发期望的牙齿移动和/或将牙齿重新定位成期望的布置。 方法和正畸系统包括在牙列中佩戴的器具的牙齿接收腔中产生过矫正。 过度矫正可以提供改进的并且更精确地施加到牙齿上的力或力矩。 过度矫正的力或力矩可使牙齿移动到比未矫正的位置更接近期望的位置,因为当牙齿接近期望的位置时仍然可以对牙齿施加足够的力。 矫正过度的力或力矩也可能更好地针对牙齿根部发生牙齿移动的生物反应。 过度纠正可以按照本文所述的各种方式进行计算。
