自锁托槽与双翼托槽滑动法关闭间隙的临床比较
Clinical comparison of space closure with sliding mechanism between self ligating bracket and twin brackets
摘要
Abstract
Objective To compare the the rate of en⁃masse space closure with sliding mechanics between 3M Smart⁃Clip self⁃ligating brackets and 3M Gemini MBT twin brackets in the first premolar extraction patients. Methods 20 Class I malocclusion patients who need first premolar extraction treatment were selected. One arch side of the second pre⁃molar and first molar were bonded with 3M self⁃ligating brackets and the other side bonded with Gemini MBT twin brack⁃ets. After leveling and alignment, 0.48 mm × 0.64 mm (0.019 inch × 0.025 inch) stainless steel wire and nickel titanium coil springs were used to close the space. An average rate of space closure per month (mm/month) was calculated in each side. Results The median rates of tooth movement for the SmartClip bracket side (1.03 mm per month) and the Gemini MBT twin brackets side (1.00 mm per month) were not significantly different (t=0.70, P=0.48). Conclusion There was no significant difference in the rate of en⁃masse space closure between SmartClip brackets and Gemini MBT twin brackets.关键词
