摘要
目的比较MRC和FRⅢ功能器矫治替牙早期前牙反的临床效果。方法选取2015年1月—2017年1月于东风口腔医院正畸科门诊收治的替牙早期前牙反患儿35例,按照就诊顺序分为MRC组18例与FRⅢ组17例。MRC组采用MRC矫治器矫治,FRⅢ组采用FRⅢ矫治器矫治。比较两组患儿治疗前后SNA、SNB、ANB、U1-SN、L1-NB、U1-L1、MP-FH指标,并记录其疗程。结果两组患儿治疗前后SNA、SNB、ANB、U1-SN、L1-NB、U1-L1、MP-FH比较,差异有统计学意义(P<0.05);治疗前及治疗后,两组患儿SNA、SNB、ANB、U1-SN、L1-NB、U1-L1、MP-FH比较,差异无统计学意义(P<0.05)。FRⅢ组平均疗程为(7.5±0.4)个月,MRC组平均疗程为(6.0±0.2)个月。结论两种矫治器矫治替牙早期前牙反均取得良好效果,但MRC矫治器治疗用时更短,患儿反馈舒适度更高。
Objective To investigate the effect of MRC and FRIII functional appliance in the treatment of early mixed dentition anterior crossbite.Methods A total of 35 children with early mixed dentition anterior crossbite were selected from January 2015 to January 2017 in Dongfeng Stomatological Hospital,which were divided into MRC group（n=18） and FR Ⅲ group（n=17） according to visiting sequence.MRC group was treated with MRC appliance,FR Ⅲ group was treated with FR Ⅲ appliance.The SNA,SNB,ANB,U1-SN,L1-NB,U1-L1,MP-FH before and after treatment were compared between the two groups,and the treatment courses were recorded.Results Before and after treatment,there were significant differences of SNA,SNB,ANB,U1-SN,L1-NB,U1-L1,MP-FH between the two groups（P〈0.05）;before and after treatment,there was no significant differences of SNA,SNB,ANB,U1-SN,L1-NB,U1-L1,MP-FH between the two groups（P〈0.05）.The treatment course of FR Ⅲ group was（7.5±0.4） months,and MRC group was（6.0±0.2） months.Conclusion Both methods can achieve satisfactory results in the treatment of early mixed dentition anterior crossbite,but the treatment time of MRC appliance is shorter,and with more convenient for patients.
