目的：通过对错牙合畸形患者的尖牙、前磨牙与其他牙（组）牙冠宽度的相关性分析，为错牙合畸形人群的尖牙、前磨牙的牙冠宽度的预测提供科学依据。方法选择南京医科大学附属口腔医院正畸科就诊的江苏籍错牙合畸形患者模型382副，按照安氏Ⅰ、Ⅱ1、Ⅱ2、Ⅲ类分组，测量牙冠宽度，进行尖牙、前磨牙与其他牙（组）的相关性分析，并建立预测方程。结果建立错牙合畸形人群的尖牙、前磨牙牙冠宽度之和的预测方程：男性U3U4U5＝0．270X ＋3．504（r2＝0．5821），L3L4L5＝0．272X ＋2．390（r2＝0．5977）；女性U3U4U5＝0．221X ＋6．884（r2＝0．4951），L3L4L5＝0．230X ＋5．173（r2＝0．5000）。X 为上、下颌中切牙和上、下颌第一磨牙牙冠宽度之和。结论本研究所建立的回归预测方程要优于Moyers 预测法，回归预测方程不因错牙合畸形安氏分类的不同而有差别。
目的：通過對錯牙閤畸形患者的尖牙、前磨牙與其他牙（組）牙冠寬度的相關性分析，為錯牙閤畸形人群的尖牙、前磨牙的牙冠寬度的預測提供科學依據。方法選擇南京醫科大學附屬口腔醫院正畸科就診的江囌籍錯牙閤畸形患者模型382副，按照安氏Ⅰ、Ⅱ1、Ⅱ2、Ⅲ類分組，測量牙冠寬度，進行尖牙、前磨牙與其他牙（組）的相關性分析，併建立預測方程。結果建立錯牙閤畸形人群的尖牙、前磨牙牙冠寬度之和的預測方程：男性U3U4U5＝0．270X ＋3．504（r2＝0．5821），L3L4L5＝0．272X ＋2．390（r2＝0．5977）；女性U3U4U5＝0．221X ＋6．884（r2＝0．4951），L3L4L5＝0．230X ＋5．173（r2＝0．5000）。X 為上、下頜中切牙和上、下頜第一磨牙牙冠寬度之和。結論本研究所建立的迴歸預測方程要優于Moyers 預測法，迴歸預測方程不因錯牙閤畸形安氏分類的不同而有差彆。

Objective To make a correlation analysis of crown widths between premolar,cuspid,and other teeth groups in malocclu-sion population. Methods Pre-treatment models of 382 patients (187 males,195 females,aged from 14 to 25 years)were selected from the records of the Orthodontic Department,Stomatology Hospital of Jiangsu Province. According to the Angle′s classification,the subjects were divided into 4 groups:Class I,Class Ⅱ division 1,Class Ⅱ division 2,and Class Ⅲ. The mesiodistal dimensions of teeth were measured using callipers (accurate to 0. 02 mm). Then crown width correlation was analyzed and the prediction equation was set up. Results The correlation coefficients had significantly statistical difference. Equations predicting summation of mesiodistal crown-widths of upper and lower unerupted canine and premolars in male and female were established respectively. The male:U3U4U5 =0. 270X + 3. 504(r2 = 0. 5821),L3L4L5 = 0. 272X + 2. 390(r2 = 0. 5977). The female:U3U4U5 = 0. 221X + 6. 884(r2 = 0. 4951), L3L4L5 = 0. 230X + 5. 173(r2 = 0. 5000)(X represents the summation of the mesiodistal crown widths of upper and lower central inci-sors and first molars). Conclusions The equations predicting summation established by this research were more precise than Moyers regression scheme,and were not influenced by the Angle′s classification.
