改良上颌牙合垫式活动矫治器在前牙牙性反牙合矫治中的疗效观察(1)
【摘要】 目的：观察两种矫治器的临床应用效果，探讨矫治前牙牙性反的新方法。方法：选择52例前牙牙性反患者，对照组26例采用改良上颌垫式活动矫治器进行矫治，传统组26例采用传统的上颌垫式活动矫治器进行矫治，矫治期间定期观察两种矫治器的稳定性，双曲舌簧性能、矫治完成时间等。结果：改良组矫治器稳定性、双曲舌簧性能明显高；4周内解除反者20例(传统组8例、改良组12例)，7周内解除者14例(传统组6例、改良组8例)，13周内解除者15例(传统组9例、改良组6例)，17周内解除者2例(均为传统组)，失败1例(传统组)，改良组矫治完成时间明显少于传统组(P<0.05)。结论：改良上颌垫式矫治器矫治前牙牙性反临床效果明显优于传统型上颌垫式活动矫治器。

【Abstract】 Objective：To observe the clinical application effect of two types of appliance，and explore the new method for rectification.Method：52 cases with anterior crossbite were selected，26 cases in the improved group were using modified maxillary teeth pad activity malocclusion subjects and the traditional group of 26 patients using traditional maxillary teeth pad activity malocclusion subjects，two correctional treatments during regular observation of stability，hyperbolic reed performance，correct completion time，and so on were observed.Result：The correcting device stability and improved performance of hyperbolic reed in the improved group were higher.20 cases of 4 weeks to lift the splint(the traditional group was 8 cases，12 cases in the improved group)，in 7 weeks were 14 cases(the traditional group was 8 cases，6 cases in the improved group)，13 weeks to lift the 15 cases(the traditional group was 9 cases，6 patients in the improved group)，17 weeks to lift 2 cases(all the traditional group)，failure in 1 case(the traditional group).The correct finish time in the improved group was obviously less than that in the traditional group(P<0.05).Conclusion：The clinical treatments effect of the improved modified maxillary teeth or pad and correcting device is superior to traditional maxillary teeth pad activity and correcting device.

前牙反是一种临床上常见的错畸形，可发生于乳牙期、替牙期及恒牙期，早期仅表现为个别或多数上、下前牙的覆、覆盖关系异常，即出现反覆、反覆盖，这种异常的咬合关系不仅阻碍了上前牙的唇向开展，也间接地影响了上颌骨的向前生长发育，同时易引起咬合创伤，颞颌关节病变等，反形成后，多不能自行消退，而是随生长发育不断加重，部分患者可出现严重的颅颌面畸形，影响患者的口腔功能、面部形态及心理健康[1]，因此，前牙反多提倡早发现、早诊断、早治疗(部分唇腭裂患者除外)，及时解除反，消除影响上颌正常发育的障碍，阻断病情的进一步发展[2-3]。对于单纯的前牙牙性反，目前诊治的方法有活动矫治器、固定矫治器、简单的功能性矫治器等，大多数的病例可以应用上颌垫式活动矫治器进行治疗，传统的上颌垫式活动矫治器在临床应用中有许多缺点，影响矫治效果，笔者将其进行改良，大量应用于临床，效果良好。
