摘要:
[摘要]目的：探讨锥形束CT（CBCT）和3D打印技术运用于青少年正畸治疗的效果及其对外观的影响。方法：选取2016年3
月-2018年8月笔者医院就诊的46例接受正畸治疗的青少年患者为研究对象，根据随机数字表法分为观察组和对照组，每组
23例。观察组：行CBCT检查，通过Mimics软件将患者的CBCT数据转化成计算机辅助设计（CAD）模型，在软件上模拟牙齿移
动、设计个体化舌侧正畸托槽。将文件转化成STL文件后导入3D打印机，制成个体化舌侧托槽；对照组：正畸治疗给予常规
舌侧托槽与粘接。记录两组正畸治疗前和治疗后6个月的临床效果、舒适度、拥挤度、Bolton值、微笑相、正面相测量值和
并发症发生率。结果：观察组托槽脱落例数显著少于对照组（P ＜0.05）；治疗后，观察组鼻唇角、颏沟倾角、上唇长、上
唇厚均大于对照组（P＜0.05），而两组H角、面型角、下唇长、下唇厚比较均无明显差异（P＞0.05）；治疗后，观察组GI和SBI
均小于对照组（P＜0.05）；观察组舒适度高于对照组（P＜0.05）；治疗后，观察组上、下列牙拥挤度、前牙Bolton值和全牙
Bolton值均小于对照组（P＜0.05）；观察组W2/W1和W3/W2低于对照组（P＜0.05），且C2/L1和C3/L1高于对照组（P＜0.05）；观
察组并发症发生率显著小于对照组（P ＜0.05）。结论：在青少年正畸治疗中，应用CBCT和3D打印技术制作个体化的舌侧托槽可
取得良好的临床效果，托槽固定位置准确、不易脱落，对牙龈损伤程度较轻，患者侧貌美观可得到明显的改善。

Abstract:
Abstract: Objective To explore the effect of cone beam CT（CBCT）combined with 3D printing technology on teenagers’
orthodontic treatment and its infl uence on appearance. Methods 46 adolescent patients treated with orthodontic treatment from
March 2016 to August 2018 in our hospital were divided into experimental group and control group by random number table
method，23 patients in each group. Experimental group underwent CBCT，transforming patients’ CBCT date into computer
aided design（CAD）model，simulating teeth movement and designing individuation lingual orthodontic brackets on the software.
Making individuation lingual orthodontic brackets by sending to 3D printer after transforming document to STL format. Using routine
lingual orthodontic brackets and its sticking on patients in the control group. Clinical effect、degree of comfort、the degree of dental
crowding、the Bolton ratios、smile analysis、frontal photographs and the incidence of complication. Results The number of bond
failure in the experimental group was lower than that in the control group（P＜0.05）.After treatment,improvement of CU and
WU4 in the experimental group were higher than those in the control group（P ＜0.05）.There were no statistical difference
between the control group and the experimental group in the WU3、WU5、WL3、etc（P ＞0.05）.After treatment，GI and
SBI in the experimental group were lower than those in the control group（P ＜0.05）. Degree of comfortin the experimental
group was higher than that in the control group（P ＜0.05）.After treatment，the degree of dental crowding of the maxillary
and mandibular teeth、the Bolton ratios of front teeth and overall teeth in the experimental group were lower than those in the
control group（P ＜0.05）.After treatment，nasolabial angle、Pog′B′-FH、the length of upper lip、the thickness of lower lip
in the experimental group were higher than those in the control group（P ＜0.05）,there were no statistical difference between
the control group and the experimental group in the H angle、G-Sn-Pos、the length and thickness of lower lip（P ＞0.05）.
The incidence of complication in the experimental group was lower than that in the control group（P ＞0.05）.Conclusion
Using CBCT and 3D printing to make individuation lingual orthodontic brackets in teenagers’ orthodontic treatment can obtain
obvious clinical effect.The adhesive position of brackets were accurate and them abscission diffi cultly，the extent of gingival
injury is relatively minor，and patients’ profi le can be improved.
