The aim of this study was to compare two intra-oral molar distalization procedures, involving 15 cases with Class II molar relationships. Magnetic devices were applied to the upper right first molars in each case, while nickel-titanium coil springs were used against the upper left first molars, for a period of 3 months. Measurements were made from lateral cephalograms and from photocopies of models taken before and after the distalization procedure. Although upper molar distalization was achieved with ease in both techniques, nickel-titanium coil springs were found to be the more effective in terms of movement achieved.
本研究旨在比较两种口腔内磨牙远移程序，涉及15例Ⅱ类磨牙关系的病例。在每种情况下，将磁性装置应用于右上第一磨牙，同时使用镍钛螺旋弹簧作用于左上第一磨牙，持续3个月。通过侧位头影测量片以及远移程序前后模型的影印件进行测量。尽管两种技术都能轻松实现上颌磨牙远移，但发现镍钛螺旋弹簧在实现的移动方面更有效。
