【摘要】：目的分析正畸正頜聯(lián)合治療的顏面不對稱患者頭顱定位后前位片測量指標的非對稱性。方法選取不同程度顏面不對稱患者45例,對所有患者治療前后頭顱定位后前位片進行測量,采用單樣本t檢驗將治療前測量指標的非對稱率與個別正常人群的非對稱率進行比較,通過相關(guān)系數(shù)的分析,歸納出顏面不對稱患者傾向于采用正畸正頜聯(lián)合治療的測量指標,并得出其參考值。同時通過配對t檢驗比較治療前后測量指標非對稱率的差異。結(jié)果有14項指標治療前的非對稱率與個別正常人群的非對稱率相比差異有統(tǒng)計學(xué)意義(P0.05)。45例患者中與Me[X]具有較高直線相關(guān)關(guān)系的指標為Ag[X]。28例患者以下頜骨體部不對稱為主,15例患者以下頜升支不對稱為主,2例患者同時存在下頜體部和下頜升支的不對稱。Me[X]等15項測量指標治療前后差異均有統(tǒng)計學(xué)意義(P0.05)。結(jié)論顏面部的不對稱主要集中在面下1/3,以下頜體部不對稱為主要表現(xiàn)。當與Me[X]具有高度直線相關(guān)關(guān)系的指標Ag[X]的非對稱率大于參考值下限11.31%,Go[X]的非對稱率大于參考值下限9.79%,且Me[X]大于參考值下限5.2 mm時,該患者的治療方案更傾向于正畸正頜聯(lián)合治療。
[Abstract]:Objective to analyze the asymmetry of posterior anterior radiographic measurements of facial asymmetry in orthodontic orthognathic patients.Methods 45 patients with facial asymmetry were measured before and after treatment.A single sample t test was used to compare the asymmetrical rate of measurement indexes before treatment with that of individual normal population. Through the analysis of correlation coefficient, the authors concluded that the patients with facial asymmetry tend to adopt orthodontic orthognathic combined treatment.The reference value is obtained.At the same time, the difference of asymmetry rate of measurement index before and after treatment was compared by paired t test.Results there was a significant difference between the asymmetry rate of 14 indexes before treatment and that of individual normal population. Among the 45 patients with me [X], there was a higher linear correlation between me [X] and me [X]: AG [X] .28 patients with mandibular body mismatch.Fifteen patients with mandibular ramus asymmetry were found to have asymmetry. Me [X] of mandibular body and mandibular ramus. There were significant differences before and after treatment (P 0.05).Conclusion the facial asymmetry is mainly concentrated in 1 / 3 of the subfacial region, and the maxillary asymmetry is the main manifestation.When the asymmetry rate of Ag [X] with a high linear correlation with me [X] was greater than the lower reference value of 11.31% and the asymmetry rate of go [X] was greater than the lower reference value of 9.79 mm, and me [X] was larger than the lower reference value of 5.2 mm, the treatment regimen of this patient was more likely to be orthodontic orthodontic orthognathic combined therapy.
