【摘要】：目的分析正畸正颌联合治疗的颜面不对称患者头颅定位后前位片测量指标的非对称性。方法选取不同程度颜面不对称患者45例,对所有患者治疗前后头颅定位后前位片进行测量,采用单样本t检验将治疗前测量指标的非对称率与个别正常人群的非对称率进行比较,通过相关系数的分析,归纳出颜面不对称患者倾向于采用正畸正颌联合治疗的测量指标,并得出其参考值。同时通过配对t检验比较治疗前后测量指标非对称率的差异。结果有14项指标治疗前的非对称率与个别正常人群的非对称率相比差异有统计学意义(P0.05)。45例患者中与Me[X]具有较高直线相关关系的指标为Ag[X]。28例患者以下颌骨体部不对称为主,15例患者以下颌升支不对称为主,2例患者同时存在下颌体部和下颌升支的不对称。Me[X]等15项测量指标治疗前后差异均有统计学意义(P0.05)。结论颜面部的不对称主要集中在面下1/3,以下颌体部不对称为主要表现。当与Me[X]具有高度直线相关关系的指标Ag[X]的非对称率大于参考值下限11.31%,Go[X]的非对称率大于参考值下限9.79%,且Me[X]大于参考值下限5.2 mm时,该患者的治疗方案更倾向于正畸正颌联合治疗。
[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.
