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.
