摘要:

目的：探讨骨性Ⅲ类错牙合畸形患者采用骨皮质切开术辅助正畸治疗的稳定性。方法：选取张家口市口腔医院2017年1 月-2018年1月收治的98例骨性Ⅲ类错牙合畸形患者为研究对象，采用随机数字法将其分为对照组(n=48)和观察组(n=50)，对照 组行常规正畸治疗，在此基础上，观察组加以骨皮质切开术治疗，比较两组患者正畸时间、矢状方向牙齿移动距离，以及两 组患者治疗前后角化龈宽度、牙位置、硬组织及软组织变化。结果：观察组的排齐时间、关闭间隙时间及总时间均明显短于 对照组(P＜0.05)；观察组的上颌中切牙矢状方向移动距离、上颌第一磨牙矢状方向移动距离均明显短于对照组(P＜0.05)； 两组治疗后角化龈宽度逐渐增加，治疗后1周最宽，随后逐渐降低，治疗后8周恢复至治疗前水平，不同时点间比较差异有统 计学意义(P＜0.05)，组间比较差异无统计学意义(P＞0.05)；治疗后1年，观察组的牙位置指标(U1I-CP、U1R-CP)均明显大 于对照组(P＜0.05)；治疗后，观察组的硬组织指标(SNA、UARA、Sd-CP)均明显大于对照组(P＜0.05)；治疗后1年，观察组 软组织指标(Ls-HP、Ls-CP、NLA)均明显大于对照组(P＜0.05)。结论：骨性Ⅲ类错牙合患者采用骨皮质切开术辅助正畸治疗稳 定性明显提升，疗效增强，治疗后恢复快，安全性较高，值得临床推广。

Abstract:

Objective To investigate the stability of skeletal Class Ⅲ malocclusion after cortical osteotomy assisted orthodontic treatment. Methods 98 patients with skeletal Class Ⅲ malocclusion in Zhangjiakou Stomatological Hospital from January 2017 to January 2018 were selected and randomly divided into control group (n=48) and observation group (n=50). The control group was treated with conventional orthodontic treatment, and the observation group was treated with cortical osteotomy. And the changes of the width of keratinized gingiva, tooth position, hard tissue and soft tissue before and after treatment in the two groups were compared. Results The alignment time, clearance time and total time of the observation group were signifi cantly shorter than those of the control group (P ＜0.05). The sagittal movement distance of maxillary central incisor and maxillary fi rst molar in the observation group were signifi cantly shorter than those in the control group (P ＜0.05). The width of keratinized gingiva increased gradually in the two groups, the widest one week after treatment, and then decreased gradually, and returned to the preoperative level 8 weeks after treatment. There was signifi cant diff erence between the two groups at diff erent time points (P ＜0.05), but there was no signifi cant diff erence between the two groups (P ＞0.05). After treatment, the tooth position indexes (U1I-CP, U1R-CP) of the observation group were signifi cantly higher than those of the control group (P ＜0.05). 1 year after treatment, the hard tissue indexes (SNA, UARA, Sd-CP) of the observation group were signifi cantly higher than those of the control group (P ＜0.05). 1 year after treatment, the soft tissue indexes (Ls-HP, Ls-CP, NLA) of the observation group were signifi cantly higher than those of the control group (P ＜0.05). Conclusion The stability of patients with skeletal Class Ⅲ malocclusion is signifi cantly improved, the curative eff ect is enhanced, the recovery is fast, and the safety is high, which is worthy of clinical promotion.
