【摘要】 目的分析Bite turbo配合早期Ⅲ类牵引治疗前牙反牙合的临床效果。方法 16例恒牙期前牙反牙合且反覆牙合深的病例,下前牙舌侧粘接Bite turbo,并同时进行早期Ⅲ类牵引,观察其疗程及疗效。结果 16例病例均快速打开咬合并解除前牙反牙合。咬合打开后SNB减小、ANB增大,下颌平面角、下面高、下面高/全面高增大,上下磨牙均伸长、下切牙被压低,反覆盖解除,覆牙合减小。结论 Bite turbo配合早期Ⅲ类牵引可以快速打开咬合,解除前牙反牙合。更多还原

【Abstract】 Objective To analyze the effect of Bite turbo combined with early class Ⅲ elastics on the treatment of anterior crossbite.Methods 16 patients with anterior crossbite and deep overbite participated in the experiment. Bite turbo combined with early class Ⅲelastics was used and the clinical effect was observed. Lateral cephalograms were taken before treatment and after bite opening. The related hard tissues were estimated through the cephalograms. Results After a short period of treatment,the anterior crossbite and deep overbite were corrected in all cases. SNB,ANB,MP-SN,ANS-Me,ANS-Me / N-Me,U1- SN,U6- PP,L6- MP,L1- MP,overjet and overbite were significantly changed. Conclusion Bite turbo combined with early class Ⅲ elastics can be used effectively for anterior crosssbite correction.更多还原
