摘　　要：目的在上颌前方牵引的基础上给予骨性Ⅲ类错[牙合](替牙期)患儿螺旋扩弓器进行扩缩处理治疗,观察疗效以及对患儿牙颌面软硬组织的影响。方法按随机数表法将2021年1月至2022年12月信阳市中心医院诊治的60例替牙期骨性Ⅲ类错[牙合]患儿分两组。对照组30例采用上颌前方牵引治疗,联合组30例在上颌前方牵引的基础上给予螺旋扩弓器治疗,评估两组临床疗效,对比两组治疗前后颌面结构、上气道间隙及三维指标。结果联合组临床有效率(86.67%)较对照组(63.33%)更高,差异有统计学意义(P<0.05)。联合组治疗后颌面结构相关指标上下颌突差(ANB)、下颌平面角(FH-MP)、下面高(ANS-Me)、腭平面角(SN-PP)较对照组更高,上中切牙的突度(L1-MP)较对照组更低,差异有统计学意义(P<0.05)。联合组治疗后上气道间隙指标鼻咽直径(PNS-R)较对照组更高,差异有统计学意义(P<0.05)。联合组治疗后上气道三维指标鼻咽段最小截面积(NP area)、鼻咽段最小截面积处冠状径(NP cor.)、鼻咽段最小截面积位置矢状径(NP sag.)、鼻咽段容积(NP volume)较对照组更高,差异有统计学意义(P<0.05)。结论上颌前方牵引联合螺旋扩弓器疗效确切,可有效促进替牙期骨性Ⅲ类错[牙合]患儿颌面结构及上气道状态恢复,改善颌面软硬组织状态。Objective To treat skeletal class Ⅲ malocclusion(mixed dentition stage)in children with spiral expansion and contraction treatment based on maxillary anterior traction,and to observe the therapeutic effect and its impact on the soft and hard tissues of the patient's teeth and maxillofacial region.Methods A total of 60 children with skeletal class III malocclusion during the mixed dentition period treated at Xinyang Central Hospital from January 2021 to December 2022 were divided into two groups using a random number table method.30 cases in the control group were treated with maxillary anterior traction,while 30 cases in the combination group were treated with spiral expanders on the basis of maxillary anterior traction.The clinical efficacy of the two groups was evaluated,and the maxillofacial structure,upper airway gap,and three-dimensional indicators before and after treatment were compared.Results The clinical effective rate of the combination group(86.67%)was higher than that of the control group(63.33%),and the difference was statistically significant(P<0.05).After combined treatment,the indicators related to maxillofacial structure in the combination group were higher than those in the control group,including ANB,MP-FH,ANS-Me,and SN-PP.The protrusion of L1-MP was lower than that in the control group,and the differences were statistically significant(P<0.05).The PNS-R of the combined group after treatment was higher than that of the control group,and the difference was statistically significant(P<0.05).After combined treatment,the three-dimensional indicators of the upper airway including NP area,NP core,NP sag,and NP volume were higher in the combination group compared to the control group,and the differences were statistically significant(P<0.05).Conclusion The combination of maxillary anterior traction and spiral expander has a definite therapeutic effect,which can effectively promote the recovery of maxillofacial structure and upper airway status in children with skeletal Class Ⅲ malocclusion during
