[摘要]目的：用腭皱测量法与传统测量法比较正畸患者拔牙与非拔牙矫治前后上颌牙弓宽度的改变量，检测并比较两种测
量方法在临床工作中的应用效果。方法：依据纳入与排除标准选取正畸患者40例，按照拔牙方式分为两组，拔牙组与非拔
牙组，分别使用传统尖牙间（C-C）、前磨牙间(P-P)及磨牙颊尖间(M-M)宽度测量方法和以腭皱前(A)后(B)为参照测量牙齿
颊面宽度的方法测量正畸矫治前后上颌石膏模型牙弓宽度。得到的数据进行拔牙组与非拔牙组组间及矫治前后组内的配对t
检验，P ＜0.05为差异有统计学意义。结果：①拔牙组中，腭皱法测得的牙弓宽变化量（A1）明显小于传统法测得的C-C1间
牙弓宽变化量，治疗前后与组间差异均具有统计学意义；腭皱法B1牙弓宽度变化量明显大于M-M1间牙弓宽度变化量，治疗
前后与组间差异均具有统计学意义（P ＜0.05）；②非拔牙组中腭皱法测得的B2上颌牙弓宽度变化量与传统法测得的M-M2间
牙弓宽度变化量差异不大，治疗前后与组间差异均具有统计学意义（P ＜0.05）；非拔牙组中腭皱法测得的A2牙弓宽度变化
量与传统法测得的上颌C-C2部牙弓宽度变化量差异不大，治疗前后与组间差异均具有统计学意义（P ＜0.05）；③正畸治疗
结束后，采用拔牙、非拔牙矫治，除传统方法得到的拔牙组上颌磨牙间宽度轻微减少外，上颌牙弓宽度均增加。结论：两
种方法均可以测量牙弓宽度的变化，拔牙矫治时以腭皱为标志点的测量方法更能真实反映牙弓宽度变化的改变量，非拔牙
矫治时两种测量方法均可使用；拔牙、非拔牙都影响矫治前后上颌牙弓宽度的改变，且不会造成上颌前部牙弓缩窄，影响
微笑美观。

Abstract:
Abstract: Objective To compare the changes of maxillary arch width before and after treatment of tooth extraction and nontooth
extraction in orthodontic patients by palatal wrinkle measurement and traditional measurement, and to detect and compare
the clinical effects of the two measurement methods. Methods According to the standard selection of orthodontic patients into
and out of 40, divided into two groups according to the tooth extraction way, tooth extraction group and the tooth extraction
group ,respectively, using traditional between teeth (C-C),(P-P) between premolar and molar buccal tip (M-M) between the
width of the measurement method and in palatal wrinkle before (A) and (B) as the reference measurement method of buccal
teeth width measurement before and after orthodontic treatment for maxillary dental arch width gypsum model. The obtained
data were analyzed by SPSS 22.0 software, and paired t-test was performed between the tooth extraction group (group 1)
and the non-tooth extraction group , before and after correction, and P ＜0.05 was used to determine that the difference was
statistically significant. Results ①In the tooth extraction group, the change of arch width measured by palatal wrinkling
method (A1) was signifi cantly smaller than that measured by traditional method between c-c1, and the difference between the
two groups before and after treatment was statistically signifi cant. The change of the arch width of B1 with palatal wrinkle
method was signifi cantly greater than that between m-m1, and the difference before and after treatment and between groups was
statistically signifi cant (P ＜0.05). ②In the non-tooth extraction group, there was no signifi cant difference between the changes
in the maxillary arch width of B2 measured by the palatal wrinkle method and the changes in the arch width of m-m2 measured
by the traditional method, and the differences before and after treatment and between the groups were statistically signifi cant
(P ＜0.05). The changes in arch width of A2 measured by palatal wrinkle in non-tooth extraction group were not signifi cantly
different from the changes in arch width of c-c2 in the upper jaw measured by traditional method, and the differences between
the two groups before and after treatment were statistically signifi cant (P ＜0.05). ③After the end of orthodontic treatment, tooth
extraction and non-tooth extraction were used for orthodontic treatment. In addition to the slight decrease in the intermaxillary
molar width of the tooth extraction group obtained by traditional methods, the arch width of the maxillary teeth was increased.
Conclusion The two methods can be used to measure the change of arch width. The measurement method with palatal crease
as the mark point in the treatment of tooth extraction is more able to refl ect the change of arch width. The two methods can be
used in the treatment of non-tooth extraction. Both tooth extraction and non-tooth extraction affect the change of maxillary arch
width before and after correction, and will not cause the anterior maxillary arch narrowing, affecting the aesthetic smile.
