| 目的 探讨上颌快速扩弓结合前方牵引治疗上颌发育不足的骨性Ⅲ类错〖XC牙合5号.TIF;%85%85,JZ〗畸形患儿的临床疗效。方法 回顾性分析60例上颌发育不足的骨性Ⅲ类错〖XC牙合5号.TIF;%85%85,JZ〗畸形患儿的临床相关资料,其中30例以上颌快速扩弓结合前方牵引的方法进行治疗(观察组)；其余30例以单纯前方牵引的方法进行治疗(对照组)。比较前牙反〖XC牙合5号.TIF;%85%85,JZ〗解除时间,以及两组患儿软硬组织的变化。结果 两组患儿的前牙反〖XC牙合5号.TIF;%85%85,JZ〗的解除时间比较,观察组(2.4±1.1)个月显著低于对照组(7.7±2.5)个月(P<0.05)。在硬组织方面,观察组患儿在上下齿槽座角、腭平面与前颅底平面的交角、下颌平面与前颅底平面成的前下交角及上下齿槽座点向功能〖XC牙合5号.TIF;%85%85,JZ〗平面投影间的距离与对照组相比改善效果明显更好(P<0.05)。在软组织方面,观察组患儿在面凸角和上下唇审美平面距等指标上,改善效果显著优于对照组(P<0.05)。结论 上颌快速扩弓结合前方牵引,能够明显改善患儿的凹陷型侧貌和颌骨横向发育不调的情况,可用于上颌发育不足的骨性Ⅲ类错〖XC牙合5号.TIF;%85%85,JZ〗畸形患儿的治疗。 |

| Objective To explore the effect of rapid maxillary expansion combined with maxillary protraction on Class Ⅲ patients with maxillary dysplasia.Methods Retrospective analysis was made of clinical data about 60 cases of Class Ⅲ children,including 30 cases treated by rapid maxillary expansion combined with maxillary protraction in the research group and another 30 cases treated with simple maxillary protraction in the control group.Front teeth occlusal lift time and change in soft and hard tissue were compared between the two groups.Results Front teeth occlusal contact time in the research group was significantly lower than that in the control group(P<0.05).In terms of hard tissue,AB plane angle,cut angle between palatal plane and SN plane,anterior inferior cut angle between mandibular plane and SN plane,and the distance between the projections of functional occlusal planes from Asubspinale and Bsupramental in the research group(2.4±1.1 months) was more effectively improved than those in the control group(7.7±2.5 months)(P<0.05).In terms of soft tissue,the improving effect in the side lobe and aesthetic plane distance between upper and lower lips in the research group were significantly better than those in the control group(P<0.05).Conclusions Rapid maxillary expansion combined with maxillary protraction can obviously improve the children's umbilicate side face and the condition of transverse maxillary hypoplasia,which can be used in the treatment for Class Ⅲ children with maxillary dysplasia. |
