摘要:
[摘要]目的：探究掩饰性正畸矫治对骨性Ⅲ类错牙合患者软、硬组织的影响。方法：对骨性Ⅲ类错牙合共61例患者行掩饰性正畸
矫治。比较治疗前后患者牙弓长度、牙弓宽度、软组织投影值及硬组织投影值等指标。结果：牙弓长度比较，治疗后患者上
颌的中段长度增加、下颌的前段长度减少，且均具有统计学意义（P ＜0.05）；其余指标则无统计学差异（P ＞0.05）。牙弓
宽度比较，治疗后患者下颌的前段宽度减少，且具有统计学意义（P ＜0.05）；其余指标则无统计学差异（P ＞0.05）。治疗
后患者软组织投影Z-plane、NLA、UL-E线均增加、LL-E线减少，差异具有统计学意义（P＜0.05）。治疗前后患者硬组织投
影ANB、A0-B0负值减少，NP-FH、UI-SN、UI-NA增加，UI-LI减少，差异均具有统计学意义（P ＜0.05）；其余指标则无统计
学改变（P ＞0.05）。结论：掩饰性正畸矫治骨性Ⅲ类错牙合效果显著，能有效扩展牙弓，调整上下牙弓相对位置，改善错牙合
和覆盖，提高患者面部协调美观程度，值得临床推广使用。

Abstract:
Abstract: Objective To explore the effects on soft and hard tissues in patients with class Ⅲ malocclusion by disguised
orthodontic treatment. Methods 61 patients with class Ⅲ skeletal malocclusion were treated with disguised orthodontic
treatment. The dental arch length, arch width, soft tissue projection and hard tissue projection were compared before and
after treatment. Results After treatment, the maxillary middle length increased and the mandibular anterior length decreased
(P ＜0.05), but there was no significant difference in other indexes (P ＞0.05). After treatment, the width of anterior segment of
mandible decreased significantly (P ＜0.05), but there was no significant difference in other indexes (P ＞0.05). After treatment,
the projection of Z-plane, NLA, UL-E line increased and the LL-E line decreased (P ＜0.05). After treatment, the negative value
of projection ANB, AO-BO in hard tissue decreased, NP-FH, UI-SN, UI-NA increased and UI-LI decreased, with significant
difference (P ＜0.05), but the other indexes had no statistical change (P ＞0.05). Conclusion The effect of disguised orthodontic
treatment on class Ⅲ malocclusion is remarkable. It can effectively expand the arch, adjust the relative position of the upper
and lower arch, improve the overbite and cover, and improve the aesthetic degree of facial coordination of the patients, which is
worthy of clinical application.
