摘要:
[摘要]目的：探究自锁托槽非拔牙矫治对牙列拥挤患者牙列形态及面部软硬组织的影响。方法：选择2014年1月-2019年1月
于笔者医院口腔科就诊的270例牙列拥挤患者为研究对象，以随机数字表法分为观察组（135例）和对照组（135例），观
察组予以自锁托槽非拔牙矫治，对照组予以传统托槽矫治，两组均持续矫治10个月。观察并比较两组矫治10个月时的
矫治效果，矫治前后的牙弓宽度及面部软硬组织指标。结果：矫治10个月时，观察组成功率为96.30%，高于对照组的
80.74%（P ＜0.05）。矫治10个月时，两组上下颌第一、第二前磨牙，上下颌第一磨牙弓宽度均较矫治前增加，且观察组
高于对照组（P ＜0.05）；矫治10个月时，两组ULP、N＇-Sn-Pg＇均较矫治前降低，且观察组低于对照组（P ＜0.05）；两组
SnLs-SiL、Cm-Sn-Ls、Li-E、Ls-E、U1-FH、OP-FH、U1-L1均较矫治前升高，且观察组高于对照组（P ＜0.05）；两组SNA、
SNB、U1-NA、U1-NA距均较矫治前降低，且观察组U1-NA、U1-NA距低于对照组（P ＜0.05）。结论：自锁托槽非拔牙矫治可有
效改善牙列拥挤患者牙弓宽度、面部软硬组织指标水平，有助于促使患者面部软硬组织恢复，并提高矫治效果。

Abstract:
Abstract:Objective To investigate the effects of non-extraction orthodontic correction with self-ligating brackets correction
on dentition morphology and facial soft and hard tissues of patients with crowded dentition. Methods From January 2014 to
January 2019, 270 patients with dentition crowding were selected and randomly divided into observation group (135 cases)
and control group (135 cases). The observation group was treated with self-ligating brackets without tooth extraction, while the
control group was treated with traditional brackets. Both groups were treated continuously for 10 months. The correction effects
of the two groups 10 months after correction, and the arch width, facial soft and hard tissue indexes before and 10 months
after correction of the two groups were observed and compared. Results 10 months after correction, the success rate in the
observation group was 96.30%, which was higher than 80.74% of the control group (P ＜0.05). 10 months after correction, the
arch widths of the upper and lower first premolars and the upper and lower first molars in the two groups increased compared
with those before correction, and the observation group was higher than the control group (P ＜0.05). 10 months after
correction, ULP, N＇-Sn-Pg＇in both groups were lower than before correction, and the observation group was lower
than the control group (P ＜0.05). SnLs-SiL, Cm-Sn-Ls, Li-E, Ls-E, U1-FH, OP-FH, U1-L1 in the two groups were
higher than those before correction, and the observation group was higher than the control group (P ＜0.05). The distances
between SNA, SNB, U1-NA and U1-NA in the two groups were lower than those before correction, and U1-NA and U1-
NA in the observation group were lower than those in the control group (P ＜0.05). Conclusion Self-ligating brackets can
effectively improve the dental arch width, facial soft and hard tissue index level,promote the recovery of facial soft and hard
tissue, and improve the treatment effect.
