简介：治疗时间的长短是许多正畸患者的抱怨。本研究的目的是评估牙周膜牵张快速移动牙齿的安全性和可行性。方法：8只雄性比格犬，年龄13 ~ 16个月。实验侧行下颌第二前磨牙拔除术和降低拔牙窝近中侧骨阻力的牙槽骨手术。然后，在实验侧放置一个装置来牵引第一前磨牙远端;在对照侧，第一前磨牙用镍钛螺旋弹簧远端化。在施加正畸力后的第1、2、4、8周处死比格犬。结果：实验侧第一前磨牙移动速度明显快于对照侧（P
Introduction: Length of treatment is a complaint of many orthodontic patients. The purpose of this study was to evaluate the security and feasibility of rapid tooth movement with periodontal ligament distraction. Methods: Eight male beagles, aged 13 to 16 months, were used in this study. Extraction of the mandibular second premolar and alveolar surgery to reduce the osteal resistance on the mesial side of the extraction socket were performed on the experimental side. Then a device was placed to distract the first premolars distally on the experimental side; on the control side, the first premolars were distalized with nickel-titanium coil springs. The beagles were killed in the first, second, fourth, and eighth weeks after orthodontic force application. Results: The first premolar on the experimental side moved more rapidly than that on the control side (P
