Objective: To investigate the effects of tooth extraction on dental arch width and alveolar bone width.
目的：研究拔牙矫治对牙弓宽度和基骨宽度的影响。
Conclusion: We use L as arch length and H as chord length to bend syringe needle that is used to posterior superior alveolar nerve block anesthesia by intraoral injection. The success rate is 98%.
结论：以牙槽孔至颧下嵴起始部的弧长和弦长为标准弯制注射针头，采用口内注射法进行上牙槽后神经阻滞麻醉，成功率为98％。
Results: After treatment, in maxilla the arch width and alveolar bone width between canines were in creased(P<0.01), those were decreased between second premolars(P<0.01 ).
结果：上颌矫治后尖牙间牙弓宽度和基骨宽度明显增加（P< 0 .0 1） ，前磨牙间牙弓宽度和基骨宽度明显减小（P< 0 .0 1）。
